Embodiment Construction

[0022] As mentioned above, since the accumulator installed without clamps is directly fixed on the compressor, it is very easily affected by the vibration of the compressor, causing abnormal vibration of the accumulator and generating noise. After analysis, it is known that if the accumulator installed without clamps is used, the vibration generated during the operation of the compressor will be transmitted to the accumulator through the connected pipes and fixtures, and the natural mode of the accumulator will be excited, causing Abnormal vibration of the reservoir, resulting in noise. To solve this problem, the traditional method is to reduce the vibration amplitude and frequency of the liquid reservoir by reinforcing the outside of the liquid reservoir, but these methods are costly, complicated in structure, and the effect produced is not ideal. According to the analysis of the airflow characteristics in the liquid storage, the present invention proposes a method of setting...

Abstract

The invention relates to the technical field of compressors, in particular to a liquid accumulator for a compressor. The liquid accumulator is provided with a cylinder body, one or multiple vibrationattenuation parts are arranged in the cylinder, through holes allowing fluid to pass through are formed in the vibration attenuation parts, the vibration attenuation parts are arranged in the liquid accumulator, vibration of the liquid accumulator can be restrained, meanwhile, the natural mode of the liquid accumulator can be changed, and the phenomenon that vibration of the compressor is transmitted to the liquid accumulator, the natural mode of the liquid accumulator is motivated, and abnormal noise is caused can be avoided.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a liquid accumulator for a compressor. Background technique [0002] The accumulator (ACCUMULATOR) is an important part of the compressor, which plays the role of storage, gas-liquid separation, filtration, silencer and refrigerant buffer. [0003] The accumulator is also divided into a vertical accumulator and a horizontal accumulator. This type of accumulator is usually fixed on one side of the compressor with a fixing device. When the accumulator and the compressor are fixedly installed, it is often The liquid accumulator and the compressor are indirectly fixed and installed with clamps, but there are also installation methods in which the liquid accumulator is directly welded or bolted to the compressor without the use of clamps. The accumulator fixedly installed without clamps is very susceptible to the vibration of the compressor, causing abnormal vibration of the accu...
