Air pump is a pump, forming a vacuum. It has a huge suction force and is created by pumping air or other substances from a closed container. Why the need for such a device, what are the principles of operation, types and features, how to build a device with his own hands, — all these questions need to be explored.
What instruments are used and where
In the modern world people are very common with vacuum in everyday life. Such devices are used in braking of vehicles and air conditioning systems. There is an appliance in order to pump the air out of packages of food or bulky items.
Fixtures are used in different industries:
- Oil and gas;
There are even pumps for women and men, enhancing the blood flow in different organs. Vacuum devices are used almost everywhere, so their design is different. The main types of such devices are varied. Liquid ring developed before all the others and is used today.
For such a device need a constant supply of fluids and electricity.
The vacuum in the chamber formed by the rotation mechanism immersed in the liquid. Rotary vane — the most popular in production. Used for small, closed systems. Rotary vane pump mainly consists of 2 cameras. During operation of the rotor the air from one module is moved to the other. These pumps are of 2 types – oil and oil-free.
The creation of a manual device from a syringe
Such a manual mini-pump is very affordable, and it will easily collect any man.
To make the device from a syringe, you need to prepare:
- Hospital syringe, preferably more;
- A tube the same diameter as the tee and a syringe;
- 2 check valve.
First, flexible plastic tube is cut into 3 parts and attaches to the tee. To one tube, attach the syringe and to the other two – aquarium valves.
You can use aquarium valves of the same diameter as the tube.
One valve inserted into the air intake, the other on the issue. The motion of the piston in the syringe from the container air is pumped out. It's also possible to pour water from one vessel in the second.
The fixture of the motor pump
Own household pump at home made from ordinary automobile or Bicycle pump. The work consists of 4 consecutive steps. Namely:
- Disassembled the device and removed the cuff.
- The cuff is flipped upside down and screwed back in.
- To the pumping tube is mounted a check valve.
- On the free end of the valve wear a tube or hose of durable material.
The essence of the alteration is that it changes the direction of the stroke: when you press on the handle decreases the volume of the chamber, and the air escapes through the inverted cuff.
When lifting arm chamber to create a vacuum.
This homemade device can be useful at home, for example, when the air intake of cases for storage of pillows and bulky stuff without the help of a vacuum cleaner.
From different compressors
For pumping large volumes can produce pump with electric drive. It is impossible to pump out of the tank contained liquid, otherwise water vapor will quickly bring the device down. In order for the compressor is not broken, the system adds the equipment to dehumidify the air.
The manufacturer of the pump by the compressor is divided into 3 stages:
- Removed the filter on the compressor.
- At the entrance to the compressor attaches a tube to suck air.
- Turn on the device itself.
The pump with their hands can create with a broken refrigerator or air conditioner. The manufacturing procedure is simple and takes place in several stages. Hacksaw cropped top. Removed the motor from the housing. On the copper pipe to wear special hose and attached to a small container.
The upper part of the compressor is replaced by a new, smaller diameter. The cap can be made with the help of a soldering iron from brass foil. Linoleum is sheathed with insulation.
The pump is equipped with a tubular level gauge for monitoring the oil level (it can be made from the housing of a pen). To the suction fitting attached to the air filter, you can use the car. Between the fitting and the filter mounted system reset excess pressure. Included in the network.
How to make a vacuum pump
Liquid ring vacuum pump creates a powerful vacuum and is widely used for agricultural machinery. Work is due to the immersion of the rotating mechanism into a liquid.
Modifying aquarium compressor is not hard, the design is quite a bit modified:
- Using a screwdriver, unscrewed the mount from the body.
- Versed node, and disassembled non-return valves.
- The valves are interchanged, and the device going back.
- Pipe is connected to the vacuum region. To eliminate humidity in the housing is done with a small hole.
- Sets the system gas outlet from the tube is the right size.
The Assembly of the pump takes place in several stages. Inside of a round drum placed blade mechanism. It is set so as not to come into contact with by the body. The drum is partially filled with water.
Impeller with motor begins to rotate, and the liquid under the action of centrifugal force fills the pump.
The flow of water occurs from the pipe or tank. Puller removes the bearing. For wear in the plate inserted hairpin. When tightening the nut is, the pressing plate on the shaft.
The nuances of making the pump with their hands
The main advantages of membrane-piston pump is in its universality and absence of noise. The vacuum is forced under the influence of the piston. In Cam-driven devices, the vacuum is created by 2 main parts of the mechanism — "jaws", rotating relative to each other.
These pumps do not need to lubricate, causing them to have poor performance and require replacement parts.
Vacuum pumps can be done independently with the help of medical syringe, auto or pump, an electric compressor, the compressor from a refrigerator compressor from the aquarium. To select a specific option, to begin to determine where and why it will be used.
The pump consists of several separate parts:
- Plastic bulb with sealing cuff, which is inserted into the stock.
- Mechanism that will create vacuum by pumping air.
- The rubber tube connecting the pump with the bulb.
The stem is inserted inside the bulb, the air is evacuated and a vacuum is created. This leads to enhanced care of the air. To run pressed air valve is released or the hole covered with your finger.
The store has options of different pump configurations. But such a pump can easily make your own from scrap materials. Gets the bulb of the desired size (you can make pastry syringe or a plastic bottle), 2 bore holes. To one hole using a sealant or glue joins the pipe (silicone, rubber or from a dropper). On the second hole of the sealing cuff is attached that provides integrity and not allowing to hurt. With the help of a gasket transition tube connected to the pump.
If you want to use the vacuum pump can save a lot of money, collecting a unit of their own. However, its creation will take a lot of time and effort. For the manufacture of the device with your hands is sometimes enough to take advantage of already existing source material. What type will be selected, will directly depend on the complexity of the works and ways of use of the instrument.
