Brief description of working principle of air compressor


The screw type single-stage compression air compressor is rotated by a pair of parallel male and female rotors (or screws) in the cylinder, so that the air between the rotor slots continuously generates periodic volume changes, and the air follows The rotor axis is transported from the suction side to the output side to achieve the entire process of suction, compression and exhaust of the screw air compressor. The air inlet and the air outlet of the air compressor are respectively located at two ends of the housing, and the slots of the female rotor and the teeth of the male rotor are driven to rotate by the main motor.


The compressor is directly driven by the electric motor to cause a rotational motion of the crankshaft, and the connecting rod is caused to cause the piston to reciprocate, causing the cylinder volume to change. Due to the change of the pressure inside the cylinder, the air enters the cylinder through the air cleaner (muffler) through the intake valve. During the compression stroke, the compressed air passes through the exhaust valve due to the reduction of the cylinder volume, and the exhaust pipe is single. The valve (check valve) enters the gas storage tank, and when the exhaust pressure reaches the rated pressure of 0.7 MPa, it is automatically stopped by the pressure switch control. When the pressure of the gas storage tank drops to 0.5--0.6MPa, the pressure switch automatically starts to start.
