Problems solved by technology

[0005] At present, the scrolls in the entire circle of scrolls are of the same specification; but as mentioned above, due to the different pressures in different areas of the compression chamber, the degree of deformation of the scrolls is also different. If the entire circle of scrolls uses the same specifications, it is obviously impossible to seal the axial gaps in different pressure zones in a targeted manner

Embodiment Construction

[0048] Such as figure 1 , 2 As shown in . Scroll teeth 42. Both the ends of the first spiral teeth 41 and the second spiral teeth 42 are provided with tooth grooves, and the sealing strips 3 are fixed inside the tooth grooves. Because the first spiral teeth 41 and the second spiral teeth 42 are symmetrically distributed, and the structures and materials are exactly the same, so the following uses the first spiral teeth 41 as an example, but actually both refer to the first spiral teeth 41 and the first spiral teeth. Spiral tooth 42.

[0049] According to the magnitude of the pressure it is subjected to, the first scroll 41 is divided into three areas inwardly from its outermost end (that is, the suction end of the oil-free scroll compressor): a low-pressure area 51, a medium-pressure area, zone 52 and high pressure zone 53. The specific division method is: taking the length of the first spiral tooth 41 as the total length, extending inward from the outermost end / outermost...

Abstract

The invention belongs to the technical field of vortex compressors, and particularly relates to a vortex tooth structure of an oil-free vortex compressor. According to the technical scheme, the vortextooth structure comprises a moving vortex disc and a static vortex disc. The moving vortex disc and the static vortex disc are respectively provided with first vortex teeth and second vortex teeth. Tooth grooves are formed in the tooth faces of the first vortex teeth and the second vortex teeth, and are arranged from an outer ring to the inside in the rotating direction of the first vortex teethor the second vortex teeth. Each tooth groove is divided into a low pressure area, a medium pressure area and a high pressure area by a partitioning plate, wherein the low pressure areas are greater than the medium pressure areas, and the medium pressure areas are greater than the high pressure areas in length. Sealing strips are arranged in the tooth grooves. Different vortex teeth are creativelydesigned according to the characteristics of different zones. Sealing efficiency of the axial clearance of the vortex discs is effectively improved. Manufacturing raw materials of the vortex teeth are saved meanwhile. A brand-new idea for the development and design of the oil-free vortex compressor is provided.

Description

technical field [0001] The invention belongs to the technical field of scroll compressors, and in particular relates to a scroll tooth structure of an oil-free scroll compressor. Background technique [0002] Following reciprocating compressors, rotary compressors, and screw compressors, scroll compressors are known as new high-efficiency volumetric compressors. Compared with other types of compressors, scroll compressors have the characteristics of fewer parts, compact structure, low noise, low vibration, high efficiency and high reliability. The type and parameters of the scroll teeth of the scroll compressor directly affect important parameters such as geometry, mechanics, thermodynamics, power consumption, efficiency, etc., as well as important technical indicators such as processing performance, wear, life, and noise. key points and difficulties. [0003] During the movement of the scroll compressor, the movable scroll and the fixed scroll are constantly engaged to co...
