Air pump is a pump that empties into the void. He has enormous strength and suction created by the suction of air or other substances from closed-circuit to the tank. Why do we need such a device, what are the principles of its work, the species and characteristics, how to build the device out of his hands, — all these questions need to be explored.
What instruments are used
In the modern world, people are very common with the emptiness in the life of households. These devices are used in the braking of cars and air-conditioning systems. There is a device to suck the air parcels with food or large objects.
The edits are applied in the various sectors of the industry:
- The medicine;
- Electrical engineering;
- Of agriculture;
- Of the construction.
There are even pumps for men and women that increase the blood flow in different organs. Suction pumps are used almost everywhere, that is why their design is different. The main types of such devices are varied. Liquid ring designed before all others, and is used at the present time.
For such a device need a constant supply of liquid and electricity.
The vacuum in the cell is formed by the rotation mechanism, immersed in this liquid. Pallet — the most popular in the production. Are used for small, closed systems. Vane pump is mainly composed of 2 cameras. When using the rotor of the air from one module is moved to another. These pumps are of 2 types, oil and oil.
Creation of a device of the syringe
This manual mini-pump is very affordable, and no problem will bring together all of the world.
To make the device of the syringe, it is necessary to prepare:
- The hospital, the syringe, preferably more;
- A tube of the same diameter as the tee and the syringe;
- 2 check valves.
First of all, flexible plastic tube cut in 3 pieces and joined with a piece by t. A tube to secure the syringe, and the other two – aquarium of vannes.
You can use valves of the same diameter as the tube itself.
A valve is inserted on absorption from the air, the other on the issue. When the movement of the piston in the syringe of the capacity of the pumped air. In the same way, you can pour water from one container into the other.
Mounting of the pump
Only domestic, from the pump to the house is usually in a car or on a bike pump. The work consists of 4 successive steps. It is:
- Disassembled the device, and is extracted from cuff.
- The cuff is returned to the other side and is screwed to the back.
- At the pump, the tube is installed non-return valve.
- On the free end of the valve, put the tube or the hose of durable material.
The essence of the amendment lies in the fact that the change in the direction of the race: pressing the lever decreases the volume of the chamber, and the air escapes through the reverse of the cuff.
When you lift the arm of the camera creates a vacuum.
This home is a device that can be useful at home, for example, at the closing of the air holdalls for storage of pillows and loose things without the help of a vacuum cleaner.
Of the various compressors
For pumping large quantities, you can make an electric pump. You can't, for the pumped out of the tank contained a liquid, otherwise the water vapor quickly displays a device failure. For the compressor is not broken down in the system in addition to the equipment for the dehumidification of the air.
The manufacture of the pump with the compressor is divided into 3 steps:
- Removed the filter from the compressor.
- At the entrance to the compressor is attached to a tube to suck in air.
- Turns on the camera itself.
The pump of his own hands, you can create them using the broken refrigerator or the air conditioner. The manufacturing procedure is simple and takes place in several stages. The jigsaw is cut off the upper part. Remove the engine from the chassis. On the copper pipes which are worn special hose and is attached to the small capacity.
The upper part of the compressor is replaced by a new, smaller diameter. The cover is made using a soldering iron and solder aluminum. Top with the linoleum to the soundproofing.
The pump is equipped with a tubular level sensor to control the oil level (can be done in the case of the ordinary of the handle). The nozzle in the fitting gasket air filter, you can use the auto. Between the tubing and the filter is mounted the system of pressure relief superfluous. Included in the network.
How to make a vacuum pump
Liquid ring vacuum pump creates a powerful vacuum, and widely used for agricultural machinery. The work is due to the immersion of the mechanism of rotation in the liquid.
You change a compressor is not hard, the design enough to modify a bit:
- Use a screwdriver to loose the fixing of the chassis.
- Shed the node, and remove the non-return valves.
- The valves are reversed, and the device will return.
- The tube is attached to a vacuum region. To eliminate the humidity in the enclosure is a small hole.
- Sets the system gas outlet tube of the right size.
The assembly of such a pump occurs in several steps. The inside of the round of the drum is placed the blades of the mechanism. It is placed so as not to touch the same housing. The drum is partially filled with water.
Wheel using the motor begins to rotate, and the liquid under the action of the centrifugal force fills the pump.
The influx of water to the nozzle or tank. Remover wins rolling. For head covering in the plate to insert fasteners. When tightening the nut housing is manufactured by pressing the plate on the shaft.
The nuances of the manufacture of the pump of his hands
The main advantages of the membrane-pump piston in its universality and the absence of noise. The vacuum is under the influence of the piston. In the cam device, a vacuum is created for the account of 2 main parts of a mechanism, "cams", turning to the other.
These pumps is not necessary to lubricate, because of this they have a low productivity and require the replacement of spare parts.
The vacuum pumps, you can do it yourself with the help of a medical syringe, auto - or an electric pump of the compressor, the compressor of the refrigerator, the compressor of the aquarium. To select an option to begin with, you must decide where and why it will be used.
The pump consists of several parts:
- Plastic bulb with lip seal, in which is inserted a rod.
- The mechanism to create a vacuum by pumping air.
- Rubber Tube connecting the pump with the bulb.
The rod is inserted to the inside of the bulb, it sucks air and the vacuum. This leads to strengthening care of the air. For its launch, you press the special air valve or released from a hole closed by the finger.
In the stores there are options of the pump of different sizes. But such a pump, you can easily make the most of recycled materials. Selected from the bulb to the right size (you can make the pastry a syringe or a plastic bottle), is that of the 2 holes. A hole using a putty or adhesive joint pipe (silicone, rubber or dropper). On the second mounting hole of the sealing collar, sealing, and won't get hurt again. With the help of a putty of transition tube communicates with the pump.
If necessary, the use of a vacuum pump you can save a lot of money, the collection of an assembly independent. However, its creation will take a lot of time and effort. For the manufacture of the device, its hands, sometimes it is enough to use already the starting material. In addition, this type is selected, directly will depend on the complexity of the work and the modes of use of the device.
