Embodiment 1

[0049] Embodiment 1: as figure 1 with figure 2 As shown, a scroll air compressor sealing structure includes a movable scroll 1 and a fixed scroll 2, wherein the movable scroll 1 is provided with a movable scroll scroll tooth 1-1, and the movable scroll The scroll tooth 1-1 is provided with an orbiting scroll groove 1-2 with a certain width and depth, and an orbiting scroll sealing strip 1-3 is installed in the orbiting scroll groove 1-2.

[0050] As a preferred structure, a fixed scroll groove 2-2 is also arranged on the top of the fixed scroll turbine teeth 2-1, and a fixed scroll sealing strip 2-3 is provided in the groove.

[0051] Wherein the moving scroll groove 1-2 is in clearance fit with the moving scroll sealing strip 1-3.

[0052] When the scroll air compressor is running, when the gas passes through the gap at the top of the moving scroll seal 1-3 or the static scroll 2-3, the pressure is throttled by P i Coming to P i+1 ,

[0053] There is a side gap between ...

Embodiment 2

[0060] Embodiment 2: as image 3 As shown, a scroll type air compressor sealing structure includes a movable scroll 1 and a fixed scroll 2, and the movable scroll is provided with a movable scroll wrap 1-1, and in the The orbiting scroll scroll 1-1 is covered with a coating, the coating is rubber coating or nylon coating, the thickness of the rubber or nylon coating is 0.01-2mm, this structure is directly on the orbiting scroll The scroll tooth 1-1 is directly covered with a rubber layer or nylon layer, avoiding the installation of the orbiting scroll groove 1-2 and the orbiting scroll sealing strip 1-3 on the orbiting scroll tooth 1-1, reducing the The processing difficulty and product cost are reduced, and the orbiting scroll wrap 1-1 is covered with a coating, which reduces the vibration and axial collision noise during the movement of the orbiting and static scrolls. The working noise of the rotary air compressor is reduced by about 5-8dB, which meets the requirements of ...

Embodiment 3

[0061] Embodiment 3: as Figure 4 with Figure 5 As shown, the height of the orbiting scroll wrap 1-1 shows a downward trend with the increase of the radius of gyration, and the depth of the groove remains unchanged; further, the orbiting scroll wrap 1-1 The height tends to decrease linearly or stepwise with the increase of the radius of gyration; among them, the height of the orbiting scroll scroll at the center of the orbiting scroll 1 is h1, and along the direction of increasing radius of orbit, the scroll teeth The heights are h2 and h3 respectively, where h1>h2>h3, the height h1 is 5-10um higher than the height h2, and the height h2 is 15-20um higher than h3. When the scroll air compressor is working, the closer it is to the scroll air compressor The center position (air outlet position), the greater the gas pressure of the compressed air, the more serious the gas leakage and the more serious the wear of the sealing strip. Therefore, the smaller the radius of gyration, ...

Abstract

The invention relates to a vortex air compressor sealing structure, an air compressor and a vehicle. The vortex air compressor sealing structure mainly comprises a movable vortex plate and a fixed vortex plate. The movable vortex plate and the fixed vortex plate are provided with vortex teeth. The movable vortex plate is engaged with the fixed vortex plate. The movable vortex plate and / or the fixed vortex plate are / is provided with coatings / a coating. Each spiral tooth end portion of the movable vortex plate is provided with a groove, each spiral tooth end portion of the fixed vortex plate is provided with a groove, and the grooves are internally provided with sealing strips. The vortex air compressor sealing structure has a good sealing effect and is relatively low in noise.

Description

technical field [0001] The invention relates to the related technical fields of mechanical engineering and vehicle engineering, in particular to a scroll air compressor sealing structure, an air compressor and a vehicle. Background technique [0002] Scroll air compressors have the advantages of simple structure, low noise, high efficiency, and good reliability. At present, most scroll air compressors use oil lubrication in the working process, and lubricating oil is crucial for oil-lubricated scroll air compressors. Importantly, its function has three aspects of cooling, sealing and lubrication, but the oil-lubricated scroll air compressor cannot be used in some occasions that require the use of pure compressed gas without oil pollution, although auxiliary oil-gas separation is added at the outlet of the air compressor The system can reduce the concentration of lubricating oil in gas products, but the gas products still contain a small amount of lubricating oil components, ...
