Refrigeration compressors are typically installed on domestic or commercial refrigerators or freezers. When the refrigeration compressor works, the refrigerant enters the refrigeration system through the air suction pipe, the air suction silencer, the air cylinder, the exhaust cavity, the inner exhaust pipe and the exhaust pipe. During this process, the piston reciprocates, thereby generating vibrations. This vibration is transmitted to the housing and the suction and exhaust pipes through the inner drain pipes and the springs. Usually, a foot plate is welded on the shell, rubber pads are installed in four installation holes of the foot plate, and then the rubber pads are fixed on the bottom plate of the ice box through combination of bolts, sleeves and nuts. Thus, vibration on the shell is transmitted to the refrigerator bottom plate through the rubber pad.
