DIY water pump from a vacuum cleaner

Many of those who want to get rid of erectile dysfunction or increase the size of their penis choose to use a vacuum pump for these purposes. Exercises with this device are a simple and yet effective method of solving such problems. Of course, on today’s market you can find a large selection of such products, however, if you wish, you can make a vacuum pump yourself. In this article we will tell you in more detail about how to make a pump for penis enlargement with your own hands.

Vacuum cleaner pump

To do this, it must be equipped with an electric motor with a shaft speed of 1400 rpm (1). The motor shaft needs to be lengthened, for which a nozzle (4) is turned on a lathe, which is screwed into the motor shaft. The nozzle provides space for a bearing mounted in the suction chamber. In addition, on a lathe it is necessary to make a cup with holes (3) for the outlet hose and for the motor shaft. The glass is attached to the suction chamber with two M8 bolts (2), passed through a hole drilled in the cover.

The corresponding holes on the glass are blind, and they also have an M8 thread cut into them. A pipe is screwed into a threaded hole in the wall of the glass, onto which a rubber outlet tube is placed. The diameter of the nozzle opening must be no less than the diameter of the outlet pipe opening. The gasket between the glass and the suction chamber can be made from a plastic lid for glass jars.

To attach the cup to the motor, remove the motor cover and drill holes for the bolts. From the inside of the cover, insert M8 bolts into these holes and screw three nuts onto them. Then screw the bolts into the glass until they stop and install the engine cover in place. By turning the nuts that are locked on the bolts with a wrench, ensure that the cup is centered relative to the motor shaft. Now lock the bolts with nuts in both the lid and the glass. If the bearing in the electric motor cover is large, which does not allow making holes for the fastening bolts to match the size of the glass, you can fix the glass on the motor in another way. Take a metal disc and drill a hole in the center for the motor shaft. Weld the plate to the glass and drill holes in it for the bolts.

After installing the cup, secure the suction chamber parts. For reliability, lock the extension attachment onto the motor shaft. Attach the inlet tube flared from the side of the lid (5) to the chamber cover. To start the pump, lower the inlet tube into the water. Close it at the bottom and pour water into the chamber through the outlet pipe. Turn on the engine and after 1-2 seconds open the tap.

Pump assembly highlights:

A lathe is used to create some items, usually small round parts that, once created, need to be cleaned and finished to the desired size.
The body is made of sheet iron.
When choosing a drive, you need to take into account the features of different designs: it must be economical and simple.
Starting a concrete pump requires the presence of the following basic parts: a gearbox that reduces the gear ratio, an asynchronous electric motor with a 3-phase feed, and a reciprocating piston converter. There are special requirements for the quality of these parts, since the correctness and efficiency of the concrete pump will directly depend on them.
Everything is assembled easily: a frame is welded from metal profiles, all elements are attached to it according to the diagram, and the electric motor is connected to the switch. The gearbox is bolted to the engine, the converter is mounted, and the cable is connected to the engine.
After checking, the concrete pump must be disassembled and cleaned - the same as after each time the building mixture is prepared.
If you need to make a mobile concrete pump with your own hands, you can install it on a single-axle trailer.

How to make a water pump with your own hands: we look at the 13 best homemade options

Water at their summer cottage is required not only by the owners to comply with sanitary and hygienic standards. It is necessary for watering plants, caring for the territory and pets, refreshing and swimming in the hot summer. Agree that it is difficult to lift the entire required volume from the source manually with buckets.

However, there is a way to alleviate the difficult fate of summer residents - this is a homemade water pump. Even if you don’t have the funds to buy pumping equipment, you can become the happy owner of a useful technical device. To build it, sometimes literally just the power of thought is enough.

We have collected and systematized for you valuable information about making almost free homemade products. The models presented for consideration were tested in practice and deservedly received recognition from the owners. A thorough description of the manufacturing technology is supplemented with diagrams, photographs and video materials.

Creation of an airlift

Pumping water from reservoirs and underground sources can be organized without the help of standard pumping equipment. To do this you will need an original device called an airlift. To make such a simple but quite effective water pump with your own hands, you will need two pipes of different diameters, one of which will supply compressed air, and the second will pump out water, and a regular air compressor.

Operating principle of an airlift pump

The operating principle of the airlift, which was invented 200 years ago, is as follows. If you place two tubes in the water column, one of which will supply compressed air, this will lead to the formation of a mixture of liquid and bubbles. Such a mixture, having a lower density than water, will begin to rise up the second tube.

To see how such a water pump works, you can conduct a simple experiment by placing two tubes in a bottle of water, one of which is connected to an aquarium compressor powered by a low-power motor. When the compressor is turned on, water will begin to pour out of the second tube. The efficiency of such a water pump, usually not exceeding 70%, directly depends on several parameters - air flow, immersion depth and the total height to which the pumped water must be raised.

Design #1 – pump for liquid overflow

This pump will most likely turn out to be the simplest and cheapest, because the starting materials are literally waste, i.e. don't cost anything at all.

To implement the idea of assembling it, the following materials are needed:

plastic bottle with stopper;
plastic bottle without cork;
a piece of plastic pipe of suitable diameter;
spout hose

First, you need to make a reed valve.

Remove the gasket from the cap of the plastic bottle. We cut it in a circle so that the diameter of the gasket becomes smaller than the neck of the bottle. At the same time, you need to leave a narrow sector untouched, about 15-20 degrees.

Drill a hole in the center of the plastic bottle cap, approximately 8 mm. Insert the gasket and screw on the cut neck.

We insert a plastic pipe into the finished valve. Cut off the top of the second plastic bottle. You should end up with something similar to a funnel. We fix it on top of the plastic pipe.

We put a spout hose on the other end of the plastic pipe. The simplest homemade water pump is ready.

By moving your hand sharply up and down, we force the liquid to rise through the plastic pipe to the spout. Then the liquid will flow by gravity.

To use a surface or submersible piston pump, you need a tube well - a well, which you can also drill yourself like an Abyssinian well or drill.

What is suitable as materials

Before assembling the vacuum pump with your own hands, prepare all the necessary structural parts in advance. All of them must be safe and made of materials that are suitable for each other. Make sure that each part does not have any sharp parts.

You can use a plastic bottle as a flask - for example, one left over from water, juice, or shampoo or liquid soap; A bottle for feeding children with formula, from an aquarium soil cleaner, as well as a large syringe, which can be purchased in pharmacies and confectionery stores, are perfect.

This cylinder should be comfortable for the genital organ and contain it completely, leaving some reserve. If the cylinder size is incorrectly selected, discomfort and pain will occur. Make sure that the flask is intact and has no sharp parts.

More details

To create a vacuum effect, you need to select a seal. For this purpose, you can use a rubber gasket for pipes, especially a pipe for a dropper or a clamp. The main rule is that the size of the sealing ring must correspond to the size of the flask, otherwise the effectiveness of the application will be low, and the use of such a device will cause pain.

Next, you need to select a pump. This could be a pump used to inflate bicycle tires, balls and balls, and other devices. This pump must allow air to be pumped out of the cylinder. For this purpose, you can also choose a syringe plunger.

As a tube for pumping out air, you can try using a hose from a tonometer, or some flexible hose from a technical store; the main thing is to choose the correct diameter.

Design #2 – manual pump with direct spout

A very simple device for pumping water from a barrel or a shaft well. The advantages of this design: speed of assembly, low cost.

PVC pipe d.50mm – 1 pc.;
PVC coupling d.50mm – 1 piece;
PPR pipe d.24mm – 1 pc.;
PPR branch no. 24 – 1 piece;
PVC plug d.50mm – 2 pcs.;
piece of rubber, diameter 50mm, thickness 3-4mm – 1 piece;
check valve 15mm – 1 piece;
empty silicone bottle 330ml – 1 piece;
tightening screw clamp – 1 piece;
screw-nut or rivet – 1 piece;
union nut no. 15 – 1 pc.

We begin the assembly of the entire structure with the manufacture of a check valve.

Construction of a check valve. We prepare a check valve from a Ø 50mm plug. We drill several holes around the perimeter of the plug Ø 5-6mm. In the center we drill a hole of suitable diameter for a screw-nut pair or rivet.

Homemade electric pump pump for pumping water

Still, pumping water using electricity is noticeably more pleasant than doing it manually. This decision is prompted by the presence of electricity on the site, as well as a suitable electric motor.

You might like to use a small electric pump to draw water from a nearby body of water. Such a device is also suitable for constructing a waterfall or small fountain on the site.

In this case, to demonstrate the operation of the structure, a drill is used, which should be replaced with a 100-1000 W motor, since the electric drill will overheat and fail during prolonged operation.

Let's look at the master class for assembling the product step by step:

Plastic, galvanization, washers and screws are necessary elements.
We prepare a cardboard template based on a circle with a diameter of 100 mm. Place the template on the plastic and trace it with a marker.
The result is the contours of one side of the pump.
We turn the template over and mark the second side of the pump. We also need a disk with a diameter of 90 mm for the impeller.
We cut out plastic parts with a jigsaw. Remove burrs with a file.
We drill 7 holes with a diameter of 6 mm in each side panel.
We cut a ring 35 mm high from a plastic pipe with a diameter of 110 mm. We cut it in one place.
Warm up the workpiece with a hairdryer.
We bend the strip into a snail shape using pliers.
Lubricate the sidewall with glue for plastic at the place where it joins the snail.
We glue the snail to the side of the pump.
Drill a hole with a diameter of 12 mm in the center of the assembly.
We drill 4 holes with a diameter of 4 mm along the contour of the washer for mounting the bearing. We put the washer in place, that is, in the center of the hole in the sidewall and mark 4 holes.
We drill 4 holes with a diameter of 4 mm in the plastic.
We place the bearing on the sidewall, insert 4 screws from the inside of the volute, put on a washer and screw the nuts onto the screws. Thus, the bearing is sandwiched between the sidewall of the volute and the washer along the outer diameter, and its inner ring rotates freely.
We mark 6 diametric lines on the disk for the impeller at an angle of 60 degrees.
We mark 6 galvanized rectangles measuring 30x40 mm.
We cut out the blanks and then bend them at a distance of 10 mm from the edge of the long side at an angle of 90 degrees.
We drill two holes with a diameter of 4 mm at the base of all metal corners.
We attach the corners to the diametric lines and mark the holes for installation in the plastic disk.
We drill holes in the plastic to attach the impeller blades.
We mount the blade to the disk using screws and nuts. Then we mark the holes for the next blade and so on.
The impeller is assembled.
We insert a bolt into its central hole from the side of the blades and screw a nut onto it.
We tighten two nuts to ensure clearance between the impeller and the volute body.
We install the impeller with a bolt into the volute.
Screw the nut onto the bolt from the outside.
You will need two nuts for secure fixation.
The impeller must rotate freely in the pump housing.
We glue a plastic plate onto the snail outlet, which is necessary for the subsequent installation of the exhaust manifold.
Preparing the intake manifold parts. It is necessary to cut a square of plastic measuring 80x80 mm with a hole for the fitting and 4 holes for fastening. We mark and drill similar holes in the second side of the case.
Insert the fitting into the hole in the cover.
We secure the intake manifold to the sidewall with screws and nuts with washers.
We apply a sealant to the end of the snail.
To secure the pump in working position, we mount a wooden block to the base.
We insert screws into the holes of the housing to assemble the volute and fasten it to the support.
Reinstall the cover with the intake manifold on the screws.
We put the washers on and screw the nuts onto the screws.
The side panel outlet with the intake manifold should also have a plastic cover attached to the outside of the housing for mounting the exhaust manifold.
The exhaust manifold is similar in design to the intake manifold, but instead of a fitting, a plastic pipe is glued into the outlet hole. We glue the seal onto the exhaust manifold.
We mark and drill holes at the end of the volute, and then mount the exhaust manifold in place using screws.
We glue wooden pads to secure the drill.
Three pieces of wood should securely hold the drill in place.
We adjust the stands so that the drill chuck is in line with the pump screw.
Insert the screw into the cartridge and tighten the last one.
We fix the drill to the chuck using a galvanized strip and self-tapping screws.
We secure the handle of the electric drill in the same way.
We put the clamp on the start button and tighten it until the power tool is turned on.

Let's check the pump in action. If there are any questions or ambiguities, they can be resolved using the following video. The assembled device will prove indispensable in a critical situation, for example, if the basement of a house is flooded with water. There is no point in purchasing a factory pump for temporary use.

Design #3 – manual pump with side spout

The previous design has one, but significant drawback. The spout moves with the stem. This design is not much more complicated, but much more convenient.

The sleeve needs to be improved. Add a 50mm PVC tee to the design with a 35 degree bend. The tee must be inserted into the upper part of the sleeve. In the rod, near the piston, we drill several large-diameter holes, the main thing is not to overdo it and not to disturb the rigidity of the entire structure.

Now water will begin to pour into the space between the rod and the sleeve. When the piston moves upward, water will begin to flow into the spout.

Attraction for children

It can be difficult to surprise modern children, especially when it comes to toys. Currently, there are a variety of things and devices for the game on sale - the choice is incredibly wide. At the same time, children can have fun and enjoy themselves while playing with flying balloons. In order to make such an interesting attraction for children, you need to use not only an old vacuum cleaner along with a hose that will be located in the area of the outlet, but also some other items.

A couple of balls that are used when playing tennis.
Clean food jars designed for children.
Thin pins.
The beads are medium size and round in shape.

To begin, very carefully pierce the walls of the balls on several sides. After this, cut out the propeller that will be attached to the top of the ball. For the propeller, you need to take jars and use special stationery scissors to cut a small transverse hole. Its length should not exceed 7 cm, and its width should not exceed 1 cm. Then pierce the propeller in the center and carefully place it on the prepared pin. In order for the propeller to rotate easily, beads must be installed in its upper and lower parts. To prevent them from flying off, bend the top part of the pin as well as possible.

Design #4 – piston well pump

This pump design is suitable for wells no more than 8 meters. The operating principle is based on the vacuum created by the piston inside the cylinder. A useful homemade product can be an excellent alternative to factory-made pumping equipment and will help solve the problems of water extraction for servicing a summer cottage.

metal pipe, diameter 100mm, length 1m;
rubber;
piston;
two valves.

The performance of the pump directly depends on the tightness of the entire structure.

You will find a detailed description of the manufacturing process of a piston pump for use in a summer cottage in one of the popular articles on our website.

Step #1: Assembly of the unit sleeve

To make a pump sleeve, you need to pay attention to the inner surface; it must be even and smooth. A good option would be a liner from a truck engine.

From below, a steel bottom needs to be welded to the sleeve along the diameter of the well head. Either a reed valve or a factory valve is installed in the center of the bottom.

A cover is made for the top of the sleeve, although this part is more aesthetic, you can do without it. It is necessary to pay attention to the fact that the hole for the piston rod is made slot-like.

Step #2: Construction of the Pump Piston

For the piston you need to take 2 metal disks. Between them lay not very thick rubber 1 cm, slightly larger in diameter than the disks. Next, we tighten the disks with bolts.

As a result, the rubber disk will be clamped and a sandwich of metal and rubber should be obtained. The idea is to create a rubber rim along the edge of the piston, which will form the necessary piston-liner seal.

All that remains is to install the valve and weld the eye for the stem.

Step #3. Making a petal valve from rubber

The reed valve consists of a rubber disc of not very thick thickness. The disc size should be larger than the inlet holes. A hole is drilled in the center of the rubber. Through this hole and a pressure washer, the rubber disk is secured over the inlet holes.

When sucked, the edges of the rubber rise and water begins to flow. During the reverse stroke, clamping pressure is created: the rubber reliably blocks the inlet holes.

Step #4: Final Assembly and Installation

It is advisable to cut a thread at the head of the well and at the bottom of the pump sleeve. The thread will allow the pump to be easily removed for maintenance and will make the installation sealed.

We install the top cover and attach the handle to the rod. For comfortable work, the end of the handle can be wrapped with electrical tape or rope, laying turn to turn.

The limitation on the depth of the well is due to the theoretical impossibility of creating a vacuum of more than 1 atmosphere. If the well is deeper, you will have to modify the pump to a deep pump.

Advantages of automatic pumps for pumping concrete:

A special electronic control unit ensures uninterrupted and correct operation of the concrete pump. It is possible to select the desired mode and carry out constant monitoring.
An autonomous system for washing the concrete pump and concrete pipeline is built in, which reduces the time spent on servicing the unit.
There is lighting for working in the dark (the concrete pump itself and the working area).
A sound alarm has been installed - the warning system is working.
The ability to regulate the concrete distribution unit has been implemented.
A typical concrete pump kit includes: a concrete pipeline (up to 80 meters long), software, and a flushing system.
It is possible to add a concrete distribution boom to facilitate delivery of the mixture to the site.
The engines comply with all international standards (EURO-4 inclusive).
In the creation of concrete pumps, components from the world's best manufacturers are used, guaranteeing high quality work, reduced repair and maintenance costs, and increased service life.

A concrete pump is a very important unit on a construction site, greatly facilitating and speeding up the execution of a lot of labor-intensive tasks. It can be purchased ready-made or assembled yourself from simple parts and mechanisms. Self-assembly of a mini-concrete pump will result in a simple and effective unit that will become an indispensable assistant in construction.

Design #6 – American or spiral type

The spiral pump uses the energy of the river flow. To operate, the minimum requirements must be met: depth - at least 30 cm, flow speed - at least 1.5 m/s.

flexible hose d.50mm;
several clamps according to the diameter of the hose;
intake – PVC pipe 150mm;
wheel;
pipe reducer.

The main difficulty in such a pump is the pipe reducer. This can be found in decommissioned sewer trucks or obtained from factory equipment.

The flexible hose is attached to the wheel in a spiral using clamps. An intake made of PVC pipe 150mm is connected to one end. The second end of the hose is put on the pipe reducer.

Water is taken in by the water intake and moves in a spiral, creating the necessary pressure in the system. The lifting height depends on the flow speed and the immersion depth of the intake.

flexible hose d.12mm (5);
plastic barrel d.50cm, length 90cm (7);
polystyrene foam (4);
impeller (3);
sleeve coupling (2);

We cut an intake hole in the bottom of the barrel. Inside the barrel, it is necessary to lay the hose tightly in a spiral and connect it to the sleeve coupling.

To impart buoyancy, foam floats must be glued inside the barrel. Finally, screw on the impeller.

For this design option, the drain hose must be 25 mm. in diameter.

Air blower

From outdated models of vacuum cleaners you can make modern devices that can be used to inflate children's pools or, for example, mattresses. Most of the more modern models have not only an inlet, but also an outlet. In order to make an air blower, you will need to connect an additional hose to the outlet of the vacuum cleaner. The end result is a strong air stream.

Of course, before using an old vacuum cleaner in this way, you should thoroughly clean the container in which the dust was collected. This can be explained by the fact that during the entire time you were cleaning the house, a huge amount of dust particles accumulated in the device’s container, which at first glance may not be noticeable. Also, cleaning the container will have a positive effect on the condition of the engine, because dust in small quantities constantly gets inside it.

On a note! An air blower will become an indispensable device for those people who like to relax in the country or in their country house.

A device such as an air blower can be used to clear paths of various types of debris. To do this, it is enough to install a special nozzle at the end of the hose, which will have a narrow hole.

Those with older home cleaning devices who have their own home workshop can use an air blower for a variety of purposes. With its help, you can easily blow away any remaining dust from the surface you are going to paint. Another application would be to collect dust from metals or wood. In such a situation, an air blower becomes indispensable for removing shavings, sawdust and other particles from the surfaces of furniture and other objects.

Design #7 – wave energy pump

As the name suggests, such pumps use wave energy. Of course, the waves on the lakes are not that big, but the pump works around the clock and is capable of pumping up to 20 cubic meters per day.

float;
corrugated pipe;
two valves;
mounting mast.

The float is a pipe, a log, selected depending on the rigidity of the corrugated pipe, experimentally.

Two valves operating in the same direction are mounted in a corrugated pipe.

As the float moves downwards, the corrugated pipe stretches, resulting in water intake. When the float moves up, the corrugation contracts and pushes the water up. Therefore, the float must be quite heavy and large.

The entire structure is rigidly attached to the mast.

This design differs from the first option in that the corrugated pipe is replaced by a brake chamber. This diaphragm-based scheme is very often used in simple DIY water pumps. Such a pump is quite versatile and can receive energy from wind, water, steam, and sun.

The brake chamber should be disassembled and only two holes left for the valves.

Manufacturing suitable valves is a separate task.

copper or brass tube;
balls of slightly larger diameter - 2 pcs.;
spring;
copper strip or rod;
rubber.

For the inlet valve, cut off the tube and drill it out so that the ball sits tightly on the tube. It is necessary to ensure that the ball does not allow water to pass through. To prevent the ball from falling out, solder a wire or strip on top.

The design of the exhaust valve differs from the intake valve in the presence of a spring. The spring must be installed between the ball and the copper strip.

We cut out a diaphragm from rubber to the size of the brake chamber. To drive the diaphragm, you need to drill a hole in the center and stretch the pin. We insert the valves from the bottom of the brake chamber. For sealing, you can use epoxy glue.

It is better to find non-metal balls for valves, so they will not be subject to corrosion.

Based on the design of the two previous options, you can think about building a more advanced model.

For this pump it is necessary to drive four stakes (1) into the bottom of the reservoir. Then make a float from a log. You need to make cuts in the log so that it does not rotate when swinging on the waves.

For durability, it is recommended to treat the log with a hot mixture of kerosene and drying oil. It must be done carefully, processed in a water bath: there should be no open flame.

The log travel limiters (3) and (4) are nailed in such a way that the log does not damage the pump rod (5) during maximum movement.

What types of concrete pump designs exist?

Depending on the type of drive, concrete pumps can be hydraulic or mechanical. According to the design, pistonless and piston ones are poured. Depending on the method of movement, concrete pumps are either stationary or mobile. Despite the apparent diversity, today two types of concrete pumps are used in construction: piston (with hydraulic drive) and rotary (with mechanical drive).

In a rotary unit, the mixture is supplied by rollers equipped with the rotor housing: during the process of rotation, they press on the supply hose and the concrete is thrown out from there. But it is very difficult to make such a concrete pump yourself, since the design of the rotary type is complex, so usually piston units are assembled with your own hands.

The piston installation includes three main parts:

Piston – powers the cylinder
Cylinder - the part responsible for taking the mixture from the hopper and pumping it
Drive – usually choose hydraulic or electromechanical

Single-piston units are most often used, since double-piston units require a complex design. Operation of two-piston units is carried out thanks to an electric or diesel engine, which converts hydraulic energy into mechanical energy.

Design #8 – device from a washing machine

Often, parts or even entire units from old things remain on the farm. You can remove a centrifugal pump from a washing machine that is no longer needed. This pump is perfect for pumping water from a depth of up to 2 meters.

centrifugal pump from a washing machine;
petal valve from a washing machine or homemade one;
plug, bottle stopper;
hose;
preferably an isolation transformer.

If you use a ready-made valve from a washing machine, it needs to be modified. One hole needs to be plugged, for example using a bottle cap.

We connect the petal valve to the hose and lower it into a pit or well. Connect the second end of the hose to the pump. For the system to start working, it is necessary to fill the hose with the valve and the pump itself with water. All that remains is to connect the transformer, and the pump is ready for use.

Application in construction

A concrete pump is needed to supply the mixture to the place of its use, and also to perform work in hard-to-reach places. The unit significantly speeds up the work process, therefore it is used wherever concrete is used: the construction of residential and industrial buildings, private and multi-storey buildings, bridges, tunnels, etc.

The output of a concrete pump can be 20-150 m3/hour. Operation of the device is simple: concrete is delivered from the container to the site, automatically pumped in the required mode. The equipment can be used all year round - for this there is a diesel fuel heating system, and thermal insulation can be provided.

Maintenance of concrete pumps is simple: after each preparation of the mixture, it is enough to use a flushing pump with a water gun. The unit can operate around the clock.

Design #10 – gear water machine

The heart of this design is gear pumps for pumping oil from agricultural or truck equipment. The power steering power plant from KrAZ has similar characteristics.

pump working volume – 32 cm3;
maximum pressure – 2.1 Atm;
operating speed – 2400 rpm;
maximum permissible rotation speed – 3600 rpm;
nominal pumped volume – 72 l/min.

If possible, a motor from a washing machine is connected to such a pump. The motor of household appliances has a number of advantages: it runs on a single-phase 220V network and has a starting system (capacitor).

Pulleys and a belt may be required to obtain the required RPM. The advantage of a gear pump is that the gears are able to create the necessary suction force even without first filling it with water.

The only note: after operating the pump, to prevent corrosion of the steel gears, it is necessary to let the pump run idle for about 20 minutes.

What does the pump consist of?

As you probably know, a vacuum pump operates using differential pressure. The effect created for the genital organ by pumping is called hyperemia. It occurs due to the rarefaction of air around the penis using a vacuum. This process allows you to powerfully increase blood circulation, which leads to an increase in the size of the penis, as well as a strengthening of the erection.

Using a vacuum allows you to achieve the following effects:

I enlarged my penis by 5.5 cm

Without shame I share with everyone how I did it

Increase the impulse response between the tissues of the genital organ and the brain;
Normalize the blood circulation process;
Increase the size of the penis by several centimeters due to the enlargement of blood vessels;
Help make intimate contact longer;
Improve the body's endurance, including during sexual intercourse;
Increase the brightness of sensations during intimacy.

A properly made vacuum pump can handle all of the above tasks. Regular use of the device every day for 20 minutes will restore male strength and cope with the problem of premature ejaculation.

In order to make a pump with your own hands, you will need the following items:

A transparent cylindrical container in which the penis will be placed;
A rubber ring acts as a seal, which ensures fixation of the penis;
A pear or piston acts as a pump, allowing you to pump out air and reduce the pressure in the flask;
cabin or hose for removing pumped air.

Design #11 – pump from a bicycle wheel

Productive pump based on two wheels.

PVC sewer pipes and outlets;
bicycle wheel;
nylon rope;
small pulley;
several pistons;
mounting rod.

The operating principle of this pump is similar to that of a dragline.

First you need to build a sleeve from a sewer pipe that will be immersed in water. A drain is placed on the top of the sleeve through which water will flow. Next, install a small pulley on the bottom (a wheel rim from a wheelbarrow will do) and a bicycle wheel on top.

We attach a series of pistons along the entire length of the rope, first passing them through the sleeve. The rope should go around the pulley and the bicycle wheel.

By rotating the bicycle wheel, each piston on the rope captures water and, like an elevator, lifts it upward. The water column pours into the outlet.

What to make from an old cleaning device: a lawn mower

If you have an old, working motor from a vacuum cleaner, it can be used to make a good lawn mower. For this device, 500 watts of power will be sufficient. No less important spare part than the motor necessary for the operation of the lawn mower will perform its functions - these are the blades. For this part you will need very hard steel that is of excellent quality.

Also, for such a device you need to make or select a suitable model for the handle. An excellent solution would be a handle from an old baby stroller you no longer need. You can also take wheels and even a frame from the stroller. If we talk about the power cord, then the one that has an old vacuum cleaner will work perfectly.

Lawnmower from an old vacuum cleaner

Then you need to attach the wheels and strong, sharp blades. First, special corners with several holes are welded onto the frame. Remember: the blades should be at a height of approximately 5-7 centimeters above the level of the lawn. The average length of the handle should be approximately 90 centimeters.

The final step will be to attach the power cord and secure the mesh, which will not allow the grass to fly in all directions. If a person has at least minor skills in working with equipment, then making a lawn mower from an old working vacuum cleaner will be very simple.

Design #12 – “homemade” for a small stream

This pump can operate on an ultra-low amount of energy. Of course it’s good if there is a river or lake. But what to do if the river becomes very shallow in the summer? A swing type pump will help.

The main part of the structure is two buckets rigidly connected to each other through blocks (4). It is necessary to make a drainage system from the stream from galvanized steel (3). In order to reduce wear, a piece of plastic is placed under it. The drainage system is rigidly connected by a leash to a rope (5).

The entire system must be adjusted so that when one bucket is filled, the drainage moves to the second bucket. The energy of the buckets is transmitted through the crank (8) to the pump (10).

Principle of operation

According to the principle of pumping the finished solution, all concrete pumps are divided into three types: piston, rotary, auger

Piston

The main components of a piston concrete pump are:

two concrete-feeding cylinders with pistons, the rods of which are connected to hydraulic cylinders,
bunker for concrete mixture;
a movable S-shaped gate (valve) driven by two plunger hydraulic cylinders.

Figure 2. Concrete pump structure
Supplying concrete mixture with a piston-type installation consists of the following steps

Oil is supplied alternately to each of the hydraulic cylinders through the pump station and distributor.
During one cycle, one of the pistons of the concrete feeding cylinder, moving from the bunker, sucks in the concrete mixture from it, while the second, on the contrary, pushes out the previously collected one.
A movable gate (valve) connects the cylinder, in which the piston pushes out the poured concrete, with a pipe to which a hose or pipe is connected for supplying the mixture.

The control panel synchronizes the operation of hydraulic cylinders and gate valves.

Rotary

Rotary concrete pumps are units consisting of:

concrete receiving bunker;
pressure chamber with a rotating rotor;
concrete supply line.

Figure 3. Rotary concrete pump
Such units, unlike piston pumps, deliver the concrete mixture more evenly, but at the same time they become very hot and require more careful maintenance.

Screw

Such units with an electromechanical drive supply the concrete mixture thanks to a screw rotating in the pressure chamber.

Due to the low power and limited resource of the working body, such devices are used for small-volume concrete work.

Design #13 – Shukhov wick pump

The Russian inventor Shukhov became famous for many buildings, including the radio tower in Moscow. Below we will discuss another of his inventions - a water pump.

The pump uses a special rope to operate. This rope consists of woven cotton threads with a total thickness of 5-6 mm, enclosed in a sheath. The thread is passed through the pulleys.

When movement occurs, the rope gets wet and wraps around the pulleys. The pulley (5) with the help of a spring (4) presses the rope against the pulley (3) with force. The squeezed water flows into the tray (7). Figure “c” shows sections of pulleys (3) and (5), respectively.

To operate the entire system, an electric motor of only 5-10 watts is required. Typically, such engines have 1500 rpm.

To reduce speed and increase force, you can use a worm gear, shown in figure “c”. It is quite possible to make it by hand. To do this, you need to find a suitable gear and make a worm from wire. Small forces on the shaft allow manufacturing inaccuracies.

With your own hands you can assemble not only a pump that pumps water for domestic needs, but also a device that can be successfully used in landscaping a site. The following article will present successful options for homemade fountain pumps.

Possible errors during assembly

Creating a vacuum pump yourself is a fairly easy and quick process, however, even one small mistake can cause discomfort and pain. In addition, due to improper assembly, such a device may simply not be effective.

The most common mistakes when assembling a pump yourself include:

• Covers made of rigid material. In this case, it is necessary to use a soft, rubber structure; • The seal is too weak; • Small size of the tube – this may cause discomfort in the scrotal area; • Large tube size – will not allow vacuum to form; • The cylinder as a flask is too large; • Pump not suitable for the cylinder; • The tube is too thin and may come off during the procedure.

Operating principle

The operating principle of the devices is displacement. The operating principle is divided into two main stages:

decrease in pressure in a closed space;
time limit within which the pressure reduction must be completed.

Application

The purpose of units of this type is to pump out air, that is, to create a vacuum inside a certain container.

Vacuum pumps are used in the following areas:

Packaging units. For packaging tapes, bag production.
Chemistry. For continuous distillation of chemicals, compression of gases and drying of chemicals.
Food. For cleaning fish and vegetables, processing milk, poultry, fruits.
Printing. Compressors are used in printing and processing devices.
Environment. In this area, devices are used for aeration of structures, treatment structures, and filtration.
Medicine. Breathing apparatus and dental equipment.

The devices are classified according to the type of impeller: they are divided into vane-rotor and vortex units. Vane-rotor ones, in turn, are divided into dry and oil types.

Recommendations for use

Not every man can use a homemade penis enlargement pump. If everything is fine with an erection, and the partner is satisfied with the size of the man’s reproductive organ, it is hardly worth risking your health and using this method. However, some couples use a vacuum pump to add excitement to sexual play. A woman can use the device to quickly bring her partner to the desired erection and increase his arousal.

Indications for use of a vacuum pump:

small length or thickness of the penis;
sluggish erection or its complete absence;
insufficiently elastic penis when excited;
inability to have sex due to decreased libido;
impotence.

Doctors recommend using the device only in case of the above problems.

A homemade device must be made of high quality from reliable and safe materials so that there is no risk of injuring the reproductive organ during the procedure. If you have the following diseases, you should not use a vacuum pump:

cardiovascular;
skin;
inflammatory;
infectious;
autoimmune
atherosclerosis;
thrombosis;
penile injuries;
varicose veins in the pelvic organs;
cancerous tumors;
hemophilia (blood clotting disorders);
psychical deviations.

Enlargement of the penis or strengthening of erection with the help of a pump is only possible for those who have reached the age of 18. If the procedure is painful or causes severe discomfort, the air pressure should be reduced.

Scope of application of the screw

At its core, a screw is a solid rod with a solid helical surface located along the longitudinal axis. The auger owes its origin to the great scientist Archimedes, who invented a water-lifting machine, which was called the Archimedes screw.

Before using the screw pump, you must carefully study the instructions.

Nowadays, screws are used everywhere and in a wide variety of industries:

A meat grinder is one of the simplest and most common devices using an auger;
Screw conveyors;
Screw pumps;
All-terrain vehicle - ShN-1 auger;
Drilling mechanisms;
Ice fishing enthusiasts use an auger to drill a hole in the river ice;
The auger principle is used in drills to remove chips during operation;
Used in small arms in auger magazines;
Widely used in presses;
Often used in combines for various purposes.

The operating principle of the auger is so simple that it can be used everywhere, and examples can be given endlessly. Needless to say, even in science fiction works there are machines that use screw mechanisms. For example, miracle machines that drill through the thickness of mountains or pierce almost right through the bowels of planets.

Design features

A piston pump is a simple design for manually pumping water. A motor pump is a pump connected to a motor. The function of a motor pump includes both pumping out liquid and supplying it under pressure. The fuel for the engine can be either gasoline mixture or diesel.

Design and principle of operation

The mechanism body is a cylindrical metal part. This module can be made from a sleeve from a diesel engine, as well as from a piece of pipeline fittings. You can also use a hydraulic cylinder body, if one is available.

The piston is made from any available material - wood, plastic or metal. Rubber rings are used to seal the piston. In appearance, this design resembles a regular pump for bicycle tires, only liquid is pumped into it.

Valves are an important part of a water pumping apparatus, since the efficiency of the unit depends on them. They are usually made of elastic and durable rubber.

What is a vacuum pump

This compact device is a device for improving the functions of the male reproductive organ. Typically the pump is used after prostate surgery. But men often use this device to enlarge the penis and enhance erection.

A vacuum pump consists of a transparent cylinder-shaped flask, a short hose and a bulb for pumping air. In other words, it's just a pump for the reproductive organ. The man inserts his penis into the flask and begins to work with the pear, as a result of which he achieves the desired effect. There are two types of this device: a regular pump and a water pump (hydropump). In the second case, the pressure on the penis is exerted not by air, but by water.
