Embodiment 1

[0037] As the power mechanism in the air compression system, the compressor plays an important role in the entire air compression system. Oil-free scroll compressors are widely used in the field of clean air sources because of their oil-free compression, high efficiency, small size, light weight, and stable operation. The sealing technology of most of the existing oil-free scroll compressors is mainly to install a static disk type wire groove and a dustproof ring groove on the top of the fixed scroll disk, and install a static scroll groove in the static disk type wire groove. The sealing strip of the rotary disk and the dustproof ring are installed in the dustproof ring groove. The main function of the dustproof ring is to prevent dust, particles and other impurities outside the working area of ​​the scroll disk from entering the compression chamber, so as to avoid the reduction of compressor performance and the The damage of the rotating disk, and the sealing strip of the fi...

Embodiment 2

[0050] For ease of understanding, an example of a new type of fixed scroll is provided below for illustration. In practical applications, the dust-proof groove part will be composed of multiple arcs, which will gradually move closer to the molded wire groove part, and finally match the molded wire groove part. It forms a closed area to achieve the effect of dust prevention.

[0051] see figure 1 , figure 2 and image 3 , the second embodiment of the new fixed scroll shown in the embodiment of the present application includes:

[0052] The dustproof groove part 6 is composed of N segments of arc grooves, where N is an integer greater than zero. The outer circular arc of the i-th arc groove in the N-segment arc groove is tangent to the outer arc of the i-1th arc groove, and the inner arc of the i-th arc groove in the N-segment arc groove It is tangent to the inner arc of the i-1 arc groove, and i is an integer greater than zero and less than N+1. Such as image 3 As shown...

Embodiment 3

[0065] Corresponding to the aforementioned embodiment of the method for realizing the application function, the present application also provides an oil-free scroll compressor and corresponding embodiments.

[0066] The oil-free scroll compressor includes the above-mentioned new fixed scroll, which has been described in detail in various embodiments, and will not be described in detail here.

[0067] The oil-free scroll compressor including the novel fixed scroll can save the space for setting the dust-proof ring groove, is beneficial to the miniaturization of the compressor, and improves the installation efficiency of the compressor.

Abstract

The invention relates to a novel static scroll plate. The novel static scroll plate comprises a scroll body, a sealing groove, an air inlet and a sealing strip, wherein the sealing groove is formed in the top of the scroll body, and the width of the sealing groove is smaller than that of the top of the scroll body; the sealing groove comprises a profile groove part and a dustproof groove part, the initial end of the profile groove part is the top of the center position of the scroll body, and the tail end of the profile groove part communicates with the initial end of the dustproof groove part; the tail end of the dustproof groove part is tangent to a target peripheral arc of the profile groove part, the target peripheral arc is a peripheral arc corresponding to the profile groove part opposite to the dustproof groove part, and the dustproof groove part and the profile groove part form a closed area; the air inlet is formed in the closed area; and the sealing strip is arranged in the sealing groove. According to the novel static scroll plate, the space for arranging a dustproof ring groove can be saved, the miniaturization of a compressor is facilitated, and the mounting efficiency of the compressor is improved.
