How to make a vacuum pump do it yourself: master class

In industry, vacuum devices are needed to remove large volumes of air and gas. However, this method has been applied in everyday life, though not so long ago.

Such devices help to store food and things, pickle meat, pump out gas, as well as liquid. They can be easily purchased in stores, but they are expensive.

There is an alternative option – to make a vacuum pump with your own hands.

Household vacuuming is used to remove excess air from plastic packaging designed to store clothing or food. When air intake decreases the volume of the container, polyethylene is tight to the product.

Using this method helps to store food for a long time, it does not deteriorate even without freezing.

Things and household products (plaids, blankets, pillows) are significantly compacted in the package, as a result of which they take up much less space. It should be noted that the clothes during such storage is reliably protected from moths.

Thanks to vacuum aggregates, it is possible to process wooden products or building materials with a laminating film. Vacuum pumps are used to remove gas or steam in the home. This is necessary in order to restore the tightness of devices.

In addition, the devices have been used in split systems.

The main types of vacuum devices:

  • Water ring – their work is carried out by immersing a device in a liquid, which during rotation draws air from the center of the blade mechanism.
  • Rotor-lamellar units – often produced by two-chamber, act by the method of forcing gas from the first chamber into the second, ensuring the operation of the rotor.
  • Membrane-piston devices – a vacuum is created in them by a piston system. The compressed gas leaves the valve outside the chamber, providing a decrease in pressure and the flow of new portions. Such devices are considered one of the most versatile and silent.

If the device is needed urgently, you can quickly make a simple vacuum pump with your own hands. This will require two plastic bottles of different diameters that easily fit into each other.

One of them will play the role of a piston, so you should select tanks that are approximate in diameter, otherwise a smaller sealing layer will have to be made on the smaller one. In addition, you will need a hose from the cycle pump.

First you need to cut the neck at a higher capacity. Then, in the bottom of the smaller bottle, make a hole and insert the bottles into each other (it should be noted that seals may be needed on the inside, which can be made with scotch tape). Then screw the hose into a large container, necessarily in the opposite direction.

The device will deflate the air in the implementation of the movement of the piston from a smaller capacity.

You can make a vacuum pump for air exhausting yourself from any cuff fixture. For these purposes, even suitable devices for bicycles.

Of course, it is better to take a car pump, because with its improvement there will be much less trouble.

Step by step instructions for making:

  1. Unleash the car device.
  2. Remove the cuff and flip it the other way around.
  3. Assemble the instrument in reverse order. The difference is that the cuff is turned in the opposite direction.
  4. At the entrance to the pump, where the hose is located, by means of which the air is pumped out, screw the check valve. The latter should function by passing air from the vessel to the device. There should be no movement of air mass in the opposite direction. The check valve can be purchased separately or taken from an aquarium compressor. Immediately before installation, you need to blow into it. The one of the sides, which will not let the air through, is screwed to the pump, and the second to the tube. It should be noted that the device is quite enough to meet the needs of home, but to create a deep vacuum, it is not suitable because of low power.
