Compressor vibration and noise reduction structure

Abstract

The invention provides a compressor vibration and noise reduction structure. The vibration and noise reduction structure comprises a noise reduction shell, flexible vibration reduction rings, a firstvibration reduction base, an air outlet pipe vibration reduction portion and an air inlet pipe vibration reduction portion, wherein a compressor is arranged inside the noise reduction shell, and the multiple flexible vibration reduction rings for vibration reduction are arranged between the noise reduction shell and the compressor. The air outlet pipe vibration reduction portion is arranged between an air outlet pipe and the compressor and arranged between an air outlet pipe and the noise reduction shell for performing sealing and vibration reduction. The air inlet pipe vibration reduction portion is arranged on a first air inlet pipe and a second air inlet pipe. The first air inlet pipe penetrates through the noise reduction shell to communicate with the compressor. The air inlet pipe vibration reduction portion is used for being connected with the first air inlet pipe and the second air inlet pipe, and performing sealing and vibration partitioning between the noise reduction shell and the first air inlet pipe. According to the vibration and noise reduction structure, by arranging vibration reduction components are multiple positions, vibration transfer is greatly lowered, one layer of noise reduction shell is arranged at the outer side of the compressor, and noise transmission is lowered to the minimum extent.

Description

technical field [0001] The present invention relates to the technical field of vibration reduction and noise reduction, in particular to the vibration reduction and noise reduction of compressors, in particular to the vibration and noise reduction structure of compressors. Background technique [0002] The compressor is an important part of the air conditioner, but for a long time, the air conditioner compressor has been operating with relatively high noise and produces severe vibrations during operation, which is harmful to the air conditioner, and the noise affects people's use environment. Therefore, the application market begins to demand quieter new compressors, usually by improving the machining accuracy and installation error of the compressor to avoid severe vibration, but such improvement is not obvious enough and the cost is high. Moreover, in order to improve the operating efficiency of the compressor, the compressor rotor will often be set with a large unbalance ...

[0002] The compressor is an important part of the air conditioner, but for a long time, the air conditioner compressor has been operating with a lot of noise and produces severe vibrations during operation, which is harmful to the air conditioner, and the noise affects people's use environment

Therefore, the application market begins to demand quieter new compressors, usually by improving the machining accuracy and installation error of the compressor to avoid severe vibration, but such improvement is not obvious enough, and the cost is high

Moreover, in order to improve the operating efficiency of the compressor, the compressor rotor will often be set with a large unbalance amount. The unbalance amount of the rotor will cause the rotor to generate a lot of vibration when it rotates at high speed, and then generate a large noise. This vibration is difficult to pass Improve processing and installation accuracy to solve
