Product characteristics

The compressor is directly driven by the motor, which makes the crankshaft rotate, drives the connecting rod to make the piston reciprocate, and causes the cylinder volume to change. Due to the change of the pressure in the cylinder, the air enters the cylinder through the air filter (muffler) through the intake valve. In the compression stroke, due to the reduction of the cylinder volume, the compressed air enters the storage tank through the exhaust valve, the exhaust pipe, the check valve (check valve), and the pressure switch controls the automatic stop when the exhaust pressure reaches the rated pressure of 0.7MPa. When the pressure of the gas storage tank drops to 0.5-0.6mpa, the pressure switch will be automatically connected and started [2].
The air compressor is to provide air source power, is the core equipment of the pneumatic system, the main body of the electromechanical air source device, it is a device that converts the mechanical energy of the primary motor (usually a motor or a diesel engine) into gas pressure energy, is a compressed air pressure generating device [2]
