Description

Reciprocating piston type compressor

Technical Field

The invention belongs to the technical field of compressors, and particularly relates to a reciprocating piston type compressor.

Background

Reciprocating compressors are mainly composed of three major parts: a motion mechanism (comprising a crankshaft, a bearing, a connecting rod, a crosshead, a belt pulley or a coupling and the like), a working mechanism (comprising a cylinder, a piston, an air valve and the like) and a machine body. The compressor is furthermore provided with three auxiliary systems, a lubrication system, a cooling system and a regulation system. The working mechanism is the main component for realizing the working principle of the compressor. When the piston is operated to reciprocate periodically in the cylinder, the space (called working volume) formed by the piston and the cylinder is periodically enlarged and reduced. When the space is expanded, the gas in the cylinder expands, the pressure is reduced, and the gas is sucked; when the space shrinks, the gas is compressed, the pressure rises and the gas is discharged. The piston reciprocates once to complete the four processes of expansion, air suction, compression and exhaust in turn, which is called a work cycle. When higher pressures are required, multiple stages of compression may be employed.

Through retrieval, chinese patent CN215566434U discloses a reciprocating piston compressor, the main structure of which includes a compressor body and a motor, an air inlet is provided on the side surface of the compressor body, an isolation net is fixed at the end of the air inlet, a brushing mechanism is provided on the outer side of the isolation net, an installation frame fixed with the compressor body is provided on one side of the brushing mechanism, a first cam and a second cam are rotatably installed inside the installation frame, the first cam and the second cam are engaged with each other through a gear set, and the first cam is in transmission connection with the motor through a speed reduction transmission mechanism.
