The working principle of silent oil-free air compressor

增压机英3.jpg


Quiet: It is a miniature piston compressor. When the crankshaft of the compressor is driven by a single shaft of the motor, the working volume formed by the inner wall of the cylinder, the cylinder head and the top surface of the piston will change periodically through the transmission of the connecting rod. Piston action process of piston compressor:


1. When starting to move from the cylinder head, the working volume in the cylinder gradually increases


2. The gas moves along the intake pipe, pushes the intake valve open and enters the cylinder until the working volume reaches the maximum, the intake valve closes


3. When the piston of the piston compressor moves in the reverse direction, the working volume in the cylinder decreases and the gas pressure increases


4. 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, and the exhaust valve closes.


When the piston of the piston compressor moves in the reverse direction again, the above process repeats. That is: the crankshaft of the piston compressor rotates once, the piston reciprocates once, and the process of air intake, compression, and exhaust is realized in the cylinder, which completes a working cycle. The structural design of single-shaft and double-cylinder makes the compressor gas flow rate twice that of single-cylinder when the rated speed is constant, and the vibration and noise control is well controlled.
