Problems solved by technology

However, because it reserves a smooth surface near the top of the tooth that is higher than the tooth height of the blade-shaped tooth, the tool cannot avoid the smooth surface structure of the tooth top during machining, and cannot directly penetrate into the bottom to process The blade-shaped teeth and blade-shaped grooves with low smooth surface, even if the blade-shaped teeth and blade-shaped grooves can be processed with special-shaped tools, it will greatly increase the cost of machining

Embodiment 1

[0109] Such as figure 1 and figure 2 As shown in , the pump body of the scroll air compressor includes a movable scroll 10 and a fixed scroll 20 . The moving scroll 10 includes: the moving scroll plate 11, the moving disk sealing strip 12, the moving disk substrate 13 and the moving disk cooling fins 14; , the static disk substrate 23 , the static disk cooling fins 24 and the static disk shock-absorbing sealing strip 25 .

[0110] Further, the movable scroll 10 and the fixed scroll 20 are engaged with each other to form a plurality of crescent-shaped compression chambers.

[0111] Further, the design of intermittent fit is adopted between the movable scroll plate 11 on the movable scroll 10 and the fixed scroll plate 21 on the fixed scroll 20 to avoid the internal friction of the movable scroll 11 Abrasion occurs between the side surface and the outer surface of the stationary scroll 21 or the outer surface of the movable scroll plate 11 and the inner surface of the stati...

Embodiment 2

[0120] Such as Figure 4 As shown, labyrinth grooves 211 / 212 / 213 / 214 are opened on the scroll plate 21 of the fixed scroll 20 .

[0121] Further, the labyrinth grooves 211 / 212 / 213 / 214 are formed by drilling and / or reaming and / or boring and / or a combination of one or more processing techniques.

[0122] Further, the automatic processing machine tool sets the processing positioning program according to the spiral line of the movable scroll 10 or the fixed scroll 20 .

[0123] Further, the machining tool starts to process various shapes of labyrinth grooves 211 / 212 / 213 / 214.

[0124] Further, the machining tool gradually processes a plurality of labyrinth grooves 211 / 212 / 213 / 214 along the spiral line according to the set program.

[0125] Further, the labyrinth groove 211 / 212 / 213 / 214 can only be opened on the scroll plate of one of the movable scroll 10 or the fixed scroll 20, so as to avoid the friction between the movable scroll 10 and the fixed scroll 20. Scratching an...

Embodiment 3

[0140] Such as Figure 9-14 As shown, the labyrinth groove 211a inside the high pressure zone, the labyrinth groove 211b outside the high pressure zone, the labyrinth groove 212a inside the medium pressure zone, the labyrinth groove 212b outside the medium pressure zone, the labyrinth groove 213a inside the low pressure zone, the labyrinth groove 213b outside the low pressure zone, and the labyrinth groove 213b outside the low pressure zone. The depth H of the labyrinth groove 214a inside the low pressure area and the labyrinth groove 214b on the outer side of the ULV area 1 all the same.

[0141] Further, the depth H of the labyrinth groove 211 / 212 / 213 / 214 1 Both are 1 / 2 to 1 times the height H of the scroll plate, that is, H / 2≤H 1 ≤H.

[0142] Further, the depth of the labyrinth grooves 211 / 212 / 213 / 214 can be selected according to the sealing performance of the dynamic and static discs and the time-consuming machining.

[0143] Further, if the sealing performance require...

Abstract

The invention relates to a compressor. The compressor comprises a dynamic vortex disk and a static vortex disk; a dynamic disk scroll plate is formed on the dynamic vortex disk; a static disk scroll plate is formed on the static vortex disk; a plurality of labyrinth grooves are formed in the side surface of the dynamic disk scroll plate or the side surface of the static disk scroll plate; and thestarting end of each labyrinth groove is the top end part of the static disk scroll plate or the dynamic disk scroll plate. A sealing structure is formed through the plurality of labyrinth grooves andthe sealing structure has throttling and depressurizing effects on compressed air among various crescent compression cavities, so that the fact that the compressed air in a high-pressure cavity is leaked into a low-pressure cavity is avoided and the radial sealing property between the dynamic vortex disk and the static vortex disk is improved.

Description

technical field [0001] The invention relates to a compressor with a radial sealing structure, in particular to an air compressor with a radial sealing structure. Background technique [0002] Air compressors, also known as air compressors, are the basic products of industrial modernization and the core equipment of pneumatic systems. Since the scroll air compressor has no reciprocating mechanism, it is widely used because of its simple structure, small size, light weight, and easy automation. [0003] The scroll air compressor is mainly composed of two double-function equation scrolls, the movable and static scrolls meshing with each other. During the compression operation, the static scroll is fixed on the frame, and the movable scroll assembly is directly driven by the crankshaft or Driven by a small crank, and the movable scroll assembly is restricted by the anti-rotation mechanism, it rotates in a plane with a small radius around the center of the base circle of the fix...
