Description

Technical Field

[0001] The utility model belongs to the technical field of piston compressor accessories, and in particular relates to an inertial force balancing device for a piston compressor. Background Art

[0002] A piston compressor is a compressor that relies on the reciprocating motion of a piston to pressurize and transport gas. It is a positive displacement compressor, also known as a "reciprocating piston compressor" or a "reciprocating compressor. The inertial forces in a piston compressor are rotational inertial forces and reciprocating inertial forces. The rotational inertial forces generated by a piston compressor during operation can be balanced by a balance iron. Among the common balance iron parts currently used, the rotating parts used to reduce inertia are mostly installed in embedded contact with the mounting groove. However, since the piston compressor frequently generates rotational inertial forces during operation, and causes the balance iron to rotate frequently, the frequent rotation during operation will cause frequent friction between the rotating parts and the mounting grooves, which will cause wear on the contact surface between the rotating parts and the mounting grooves, and the heat generated during the friction process will also accelerate the aging of the parts.
