Is it possible to make a vacuum pump by one's own hands?

Vacuum pump is used for pumping out environments that are not aggressive - vapors, gas, liquids. These days these units are widely used both in industry and in everyday life. However, in the factory version, they are quite expensive. Therefore, if you want you can make a household vacuum pump with your own hands.

If we talk about the principle of the device as a whole, then it should be said that it is based on the creation of an internal vacuum. There are two large groups of vacuum pumps: water ring and membrane pumps . Depending on the device, the principle of operation is somewhat different.

You can make a vacuum pump by yourself with a water ring. In this case, the unit will have a cylindrical body, inside which is a shaft with a working wheel equipped with small blades. The principle of its action is that water is poured into the body, why the blades begin to rotate, grabbing water. The liquid in the unit spreads to the walls due to the centrifugal force.

As a result, a space is formed in the center, which is the working area. It is here that a vacuum is created. This scheme of assembly of the unit makes it possible to pump out any non-aggressive medium. For example, gas or steam. Such devices are most often used in plant equipment and agricultural machinery.

The water-ring vacuum pump can be made very realistically. It is these devices that are often chosen for work, since their functions are not limited to any design features. If you set out to make a homemade vacuum pump, most importantly, do not spare money for the purchase of quality parts. Only then you will get a good device.

In membrane aggregates, the principle of operation is that the membrane moves, thereby creating a space devoid of air. With this device, you can also pump gas, vapors and so on. At the same time, it differs in that it does not require special maintenance, it is simple and environmentally friendly in circulation, which is especially important these days. Applied most often such devices in chemical laboratories, medical equipment.

Those who are interested in how to make a vacuum pump on their own will benefit from the following information. There are several options for manufacturing such a device. For example, if you want to make a vacuum pump by yourself for the aquarium, you can use the scheme that will be described below.

You will need a plastic tee, nozzle, choke, pump core

The tee can be purchased ready, and the nozzle made from a pipe, or rather, its spout. To make a vacuum pump with your own hands, the resulting nozzle must be inserted into one of the holes in the tee. Then screw the union on the tap with a thread and pull on it ten-centimetric cut off the hose. At the second end of the hose, you need to insert the pump core, and from its opposite side attach a short hose that will drain water into the sewer.

To the main branch of the tee, attach the hose, which is lowered into the aquarium. At its end, attach the aquarium siphon so that the soil is not drawn into the pump.

When the tap is open and water comes from the system described above, a vacuum is created in the hose. This in turn leads to the fact that the water is pumped out of the container.

When the pump performs the required work, the water in the tap needs to be closed. In this case, if you remove the siphon from the aquarium, the hose will empty. After that, it can be twisted and stored until the next time. So, it becomes clear that if necessary, you can make a vacuum pump with your own hands in the home. And if you apply not only diligence, but also your imagination, you can make such a device from improvised means.
