Background technique
Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to high pressure gas, is the heart of refrigeration system
It is dirty.It is operated after compressing with piston to it, to row from the refrigerant gas of air intake duct sucking low-temp low-pressure by motor
The refrigerant gas of high temperature and pressure is discharged in tracheae, provides power for refrigeration cycle.To realize compression → condensation (heat release) → swollen
The refrigeration cycle of swollen → evaporation (heat absorption).
Common piston type air-conditioner compressor, when reciprocating motion of the pistons, all fit closely with cylinder, and abrasion loss is larger, sternly
Ghost image rings the service life of compressor, and when pistons work, force unbalance, so that vibration of compressor is larger, generates larger
Noise.
Summary of the invention
In order to make up for the deficiencies of the prior art, a kind of compressor of air conditioner vibration damping maintenance process proposed by the present invention, passes through water
Two piston relative motions of flat setting, reduce the vibration of compressor；It is controlled by telescopic unit, so that piston is bonded when compressing
