Compressor Principle

The silent oil-free low-pressure Air Compressor belongs to the micro reciprocating piston Air Compressor, and the single-axis drive of the motor is a crank-rocker mechanism with a 180 ° distribution. The main motion pair is a leather bowl piston ring, and the paid motion pair is a cylindrical surface with a protective layer of aluminum alloy. There is no need to add any lubricant between the motion pairs due to the self-lubrication of the piston ring. The compressor makes the stroke volume of the cylinder change periodically through the swing of the crank-rocker and the reciprocating motion of the conjoined piston. Due to the single-axis double-cylinder structure, when the motor rotates once, each group of cylinders will have a change in the stroke volume of the cylinder in the opposite direction. When the piston travels to the shaft, the cylinder is under negative pressure. At this time, the atmospheric pressure is greater than the pressure in the cylinder. Air enters the cylinder through the intake valve. At this time, it is the suction process. When the piston travels to the cover, the gas entering the cylinder is compressed, and the pressure increases rapidly. When the pressure is greater than the pressure acting on the exhaust valve plate, the exhaust valve is opened. At this time, it is the exhaust process. The structure of the compressor's single-shaft double-cylinder makes the compressor's exhaust volume double that of the single cylinder. The crank-rocker mechanism with a wrong angle of 180 ° makes the first-order inertial force that affects the vibration of the compressor cancel each other, so that the vibration and noise are improved and the overall structure is more compact.

Principle of low pressure Air Compressor

Due to the reciprocating movement of the piston, the air enters the compressor through the filter, and then the air is compressed, so that the compressed gas enters the air storage tank from the exhaust port through the metal hose, and the pointer of the pressure gauge rises to 0.8 Mpa, when the pressure is greater than 0.8 Mpa, the pressure switch is automatically closed, the motor stops working, and at the same time, it is evacuated through the solenoid valve to reduce the pressure in the compressor cylinder to 0. At this time, the pressure of the gas in the air switch and the gas storage tank is still 0.8 Mpa. When the gas is exhausted through the ball valve, the pressure in the gas storage tank will drop. When it drops to 0.5 Mpa, the pressure switch will automatically open and the compressor will start again. Work.
