The working principle of the refrigerator compressor is that the low-temperature low-pressure refrigerant gas is sucked from the air suction pipe, the piston is driven to compress by the operation of the rotary module, and then the high-temperature high-pressure refrigerant gas is discharged to the exhaust pipe to provide power for refrigeration cycle. Reciprocating inertial force and rotational inertial force during operation of the compressor may cause the compressor to vibrate. The vibration support plate of the compressor is transferred to the cabinet of the refrigerator, resulting in the problem of excessive vibration and noise of the refrigerator.
