Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0018] see Figure 1 to Figure 4 As shown, according to the embodiment of the present invention, a compressor stator is provided. The compressor stator includes a stator body 10 with a cut edge 11. The stator body 10 is formed by lamination of several iron core lamination stacks. The stator body 10 A cavity 12 and an introduction channel 13 are formed inside, the first end of the introduction channel 13 communicates with the cavity 12, and the second end of the introduction channel 13 forms an opening at the cutting edge 11 of the stator body 10, see figure 2 The opening of the introduction channel 13 is shown.

[0019] The cavity 12 of the stator body 10 and the introduction channel 13 form a sound-absorbing cavity, that is, a resonant sound-absorbing structure. Under the action of...

Abstract

The invention discloses a compressor stator and a compressor. The compressor stator comprises a stator body with the cut side. A cavity and a guide-in channel are formed in the stator body. The first end of the guide-in channel communicates with the cavity. An opening is formed in the portion, at the cut side of the stator body, of the second end of the guide-in channel. By the adoption of the compressor stator and the compressor, the problem that in the prior art, the noise of the whole compressor is large is solved effectively.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor stator and a compressor. Background technique [0002] The compressor noise sources in the prior art mainly include airflow pulsation noise, mechanical noise and electromagnetic noise. At present, 80% of the high-pressure gas in the compressor flows through the gap between the compressor stator and the shell. In the channel where the gap flows, the air pulsation noise is obvious. The current compressor stator structure cannot eliminate or alleviate this type of noise. As a result, the overall noise of the compressor in the prior art is large. Contents of the invention [0003] Embodiments of the present invention provide a compressor stator and a compressor to solve the problem of high overall noise of the compressor in the prior art. [0004] In order to solve the above-mentioned technical problems, the present invention provides a compressor stator, which i...
