The main structure of the piston compressor:
For piston compressors without crosshead, the main components include the body, crankshaft, connecting rod, piston, cylinder, intake and exhaust valves, etc.; for piston compressors with crosshead, in addition to the above parts, there are cross Head and slide, piston rod and stuffing box, etc.
The piston compressor uses a crank connecting rod mechanism to convert the rotary motion of the driving machine into the reciprocating motion of the piston.
The compression volume is composed of the piston and the cylinder; the piston reciprocates in the cylinder, so that the gas completes the process of air intake, compression, and exhaust in the cylinder. The intake and exhaust valves control the gas entering and exiting the cylinder; on the crankshaft side The packing seal of the cylinder end device mainly prevents gas leakage. The piston ring on the piston prevents the gas in the cylinder volume on both sides of the piston from leaking each other.
