Problems solved by technology

The base is mainly made of ordinary hot-rolled steel plates. Due to the small internal friction of ordinary hot-rolled steel plates, when forced to vibrate, the vibration-absorbing capacity is low, and it is easy to generate large-scale resonance. It is difficult to effectively attenuate noise and vibration. The impact is relatively large, so we need to find a suitable material to improve this problem

Abstract

The invention discloses a base used for a rotary compressor, the rotary compressor and refrigerating equipment. The base used for the rotary compressor is made of magnesium alloy. The base used for the rotary compressor is low in manufacturing cost, vibration and resonance caused during working of compressor assemblies and a motor can be greatly reduced, accordingly the noise of the rotary compressor is lowered, the noise value is decreased by 2 dB(A), the tone quality of the compressor is effectively improved, and influences to the surrounding environment are reduced.

Description

technical field [0001] The invention belongs to the field of compressors, in particular, the invention relates to a base for a rotary compressor, a rotary compressor and refrigeration equipment. Background technique [0002] A common rotary compressor consisting of a compression pump body assembly, motor, housing, base, and liquid reservoir. When the compressor is running, the mechanical vibration and motor noise of the pump body assembly mainly rely on the shell and base to reduce vibration and noise. The base is mainly made of ordinary hot-rolled steel plates. Due to the small internal friction of ordinary hot-rolled steel plates, when forced to vibrate, the vibration-absorbing capacity is low, and it is easy to generate large-scale resonance. It is difficult to effectively attenuate noise and vibration. The impact is relatively large, so we need to find a suitable material to improve this problem. [0003] Therefore, the existing compressor needs to be further improved....
