Embodiment Construction

[0016] Such as Figure 1 ~ Figure 3 As shown, an oil-free scroll compressor sealing structure of the present invention includes a scroll body 1, a sealing groove 2 is provided on the top of the scroll body 1, and a sealing strip 3 and a sealing liner 4 are sequentially arranged in the sealing groove 2 from top to bottom. . The sealing lining is a soft material and needs to be fixed well to ensure that the sealing lining is partially deformed and detached after being stressed, such as using high-elastic silicone rubber. The sealing strip 3 is filled with polytetrafluoroethylene material with self-lubrication and high wear resistance. There is a groove 4-1 on one surface of the sealing liner 4, which is in a toothed structure. The flat surface of the sealing liner is connected with the scroll body downwards and glued together; the toothed surface is in contact with the sealing strip, and the toothed surface of the sealing liner The spacing between the teeth is evenly distribut...

Abstract

The invention discloses a seal structure of an oil-free vortex compressor. The seal structure comprises a vortex body, and is characterized in that the top of the vortex body is provided with a seal groove; the seal groove is internally and sequentially provided with a seal strip and a seal lining from top to bottom; high-elasticity silicon rubber is adopted for the seal lining; and a self-lubricating and high-abrasion-resisting filled polytetrafluoroethylene material is adopted for the seal strip. The seal structure provided by the invention does not requires oil for lubrication and seal, has the advantages of simple power consumption, reliable seal property and long service life, is convenient to maintain and replace, and has favorable popularization value.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a scroll compressor sealing structure. Background technique [0002] Whether the scroll compressor can achieve high performance depends to a large extent on the effectiveness of sealing and lubrication. Due to the influence of machining accuracy, assembly accuracy and force on the movable scroll, the compression chamber of the scroll compressor will have certain radial and axial clearances. Effective sealing measures must be taken for these gaps. The leakage in the scroll compressor mainly includes the radial leakage through the axial meshing gap of the scroll profile and the tangential leakage through the radial meshing gap of the scroll profile. The leakage line length of the axial gap is much larger than that of the radial gap. Therefore, the sealing effect of the axial gap is much more important than the sealing effect of the radial gap. When the moving scroll is subje...
