Air compressor use concept principle

The basic concept of air compressor:

the air compressor is a pressure generating device that converts mechanical energy into gas pressure energy.

use of air compressor:

air compressor is a kind of gas power source conversion equipment, which is used in all aspects of life. In the construction, iron and steel, mining and chemical industrial plants in many uses, especially the twin-screw air compressor is widely used in machinery, metallurgy, electronic power, medicine, packaging, chemical, food, mining, textile, transportation and many other industrial fields, and become the mainstream of compressed air products.

air compressor classification and working principle

there are many types of air compressor, common screw air compressor and piston air compressor

the piston air compressor uses an electric motor or diesel engine to drive the pulley to directly drive the crankshaft through the coupling, drive the connecting rod and the piston rod, and make the piston reciprocate in the cylinder to complete the suction, compression and discharge process.

When the reciprocating piston in the cylinder moves up and down, the pressure in the left cavity of the piston in the cylinder is lower than the normal atmospheric pressure, the suction valve opens, and the outside air flows into the cylinder. This process is called the compression process. When the pressure in the cylinder is higher than the air pressure in the gas pipeline, the exhaust valve opens and compressed air is delivered into the exhaust pipeline. This process is called the exhaust process.

Single-cylinder piston ▼ Double-cylinder piston ▼ Next, the pressure-free or low-pressure gas is boosted and delivered to the gas tank. When the pressure in the gas tank reaches a certain value, the piston air compressor does not stop running but opens the safety valve. No compression operation. Another way is that when the pressure in the gas tank reaches a certain value, the compressor will automatically stop working.

Screw air compressor

it is composed of a group of two parallel screws that bite each other. When the motor drives the two screws to rotate, because the gap between the two screws and the shell is only about 10 wires, the main screw drives the auxiliary screw to rotate together, and the outside air passes through the screw teeth. It is sucked in. As the volume between the teeth of the spiral rotor rotates, the volume between the teeth decreases continuously with the bite of the rotor teeth, and the compressed pressure of the gas increases, when the rotor turns to the same pressure between the teeth and the exhaust hole, the compressed air starts to be discharged.
