Noise reducing device for vortex type compressor

Abstract

The invention discloses a noise reducing device of scroll compressor, comprising a sealed casing, a static scroll disk fixed in the sealed casing, a dynamic scroll disk fixed on the driving shaft, an outlet cover fixed on the static scroll disk and forming an out let chamber, and a high-low pressure dividing plate which divides the sealed casing into suction area and outlet area. The invention is characterized in that: on the outlet cover, multiple small through holes are formed, the compressed gas from the compressing chamber can be outlet by the small through holes. In this way, the outlet path of the compressed gas is dispersed. The invention can reduce the pulsating pressure of the compressed gas, and consequently reduced the noise from the compressor.

Description

technical field

[0001] The invention belongs to a device for reducing the discharge noise of a scroll compressor, in particular to a device for reducing the discharge noise of a scroll compressor with double support along the axial direction. Background technique

[0002] Generally speaking, turbo compressors are widely used in the field of air conditioners. As high-efficiency and low-noise compressors, their operation method is to make two turbines rotate relative to each other, so that multiple pairs of turbines are formed. The compression chamber moves rapidly to the center, and at the same time, the volume becomes smaller, so that the refrigerant gas is continuously sucked in, compressed and discharged. Such as figure 1 , 2 Shown, the structure of existing scroll compressor is: the sealing shell (1) of turbo compressor, on the lower shell (1a) of sealing shell (1), be provided with gas suction pipe (SP), The upper casing (1b) of the sealed cas...
