Principle of oil-free air compressor

Oil-free air compressor is a process in which the piston compresses and then starts to store air. When the air is released, the potential energy is converted into kinetic energy. It has a wide range of uses.

For example, bus brakes, train brakes, painting, pad printing, woodworking nail guns, sewage treatment and other places can be found everywhere in life. Oil-free air compressors mainly have the following functions:

1. Compressed air is then converted into power.

The compressed air will be partially used for refrigeration and gas separation enterprises.

The compressed air is used for synthesis and polymerization in many chemical industries.

4. Gas delivery

the above is the main function of the oil-free air compressor, so what is its working principle after we know its function?

In fact, it is very simple. When our oil-free air compressor motor is ready to start operation, air enters the compressor through the air filter inside the oil-free air compressor. At this time, the compressor will start to work and then compress the air. Then the compressed gas begins to enter the next link. It opens the one-way valve through the air flow pipe and then enters the air storage tank. After that, the pointer of the pressure gauge will change accordingly, the display table will then rise to 8 Bar.

When the display is greater than 8 Bar, the pressure switch will automatically close after sensing the channel pressure. At this time, the motor of the oil-free air compressor will stop working, and the internal solenoid valve will discharge the air pressure in the head of the oil-free air compressor to 0.

At this time, the air switch pressure will show that the gas pressure in the gas tank is still 8 Bar, and the gas will then work through the equipment connected to the ball valve exhaust drive. Of course, after this process, once the air pressure in the air storage tank drops to 5 Bar, the pressure switch will automatically open through induction. At this time, the oil-free air compressor will restart the cycle of this process. This is the oil-free air The working principle of the compressor.
