Air Pump Head

The pump head of an air compressor usually adopts a piston design, and its working principle is as follows: When the crankshaft of the piston air compressor rotates, the piston reciprocates through the transmission of the connecting rod. The working volume formed by the inner wall of the cylinder, the cylinder head and the top surface of the piston will change periodically. Specifically, when the piston starts to move from the cylinder head, the working volume in the cylinder gradually increases, and the gas enters the cylinder along the intake pipe; when the working volume reaches the maximum, the intake valve closes; then the piston moves in the opposite direction, the working volume decreases, and the gas pressure increases; when the pressure in the cylinder reaches and is slightly higher than the exhaust pressure, the exhaust valve opens, and the gas is discharged from the cylinder until the piston moves to the limit position. This process is repeated to complete a working cycle.
