Problems solved by technology

Since the axial contact force will cause sliding friction between the non-orbiting scroll and the orbiting scroll on the end plate surface, then, when the axial contact force is too large, the friction power consumption will increase a lot, resulting in a decrease in performance

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0025] See attached image 3 , the shell of the scroll compressor 1 includes a generally cylindrical main shell 2, the upper part of the main shell is welded with an upper shell 3, and the middle of the upper shell protrudes outward to form a cup-shaped The concave part 4. A base 5 is welded to the lower part of the main housing, and a plurality of mounting feet are installed on the base, which are not shown in the figure. An upper gas guide joint 6 for refrigerant is installed on the recess 4 of the upper housing, and a lower air guide joint 8 is also installed on the main housing. One end of the exhaust pipe 7 is installed in the upper air guide joint 6, and the other end is installed in the lower guide Gas connector 8. Other main components fixed on the main housing include: frame 10, which is suitably fixed on the main housing; The leg...

Abstract

The invention relates to a scroll compressor which includes a non-revolution vortex part and a revolution vortex part. An elastic deadening cavity for discharging air consists of a driving shaft which is supported by the bearing of a frame, the back lateral of the non-revolution vortex part and an upper casing commonly. The back lateral of the non-revolution vortex part is pressed to be in contact with the inner wall of the deadening cavity through a sealing component in a way of sliding. The deadening cavity is communicated with an air discharging cavity which is arranged on a motor side on the lower part of the compressor and is formed by a frame, a main casing and a sealing part in a way of sealing. The design optimizes the contact force between the non-revolution vortex part and the revolution vortex part and between the revolution vortex part and the frame in the maximal degree. The non-revolution vortex part under the pressure function of high-pressure gas in the deadening cavity on the back lateral of the non-revolution vortex part and the revolution vortex part under the pressure function of high-pressure fluid on the back lateral of the revolution vortex part are in closely contact with each other and are sealed axially. The non-revolution vortex part is arranged on an installation mechanism in a way of sliding upwards and downwards and can move axially within a certain range.

Description

technical field [0001] The invention relates to a scroll compressor, in particular to a scroll compressor that allows a certain axial displacement of a non-revolving scroll. Background technique [0002] Existing scroll compressors include a non-revolving scroll with a scroll crimp on the bottom plate and an orbiting scroll with a scroll curl on the end plate, and the two scrolls face each other Meshing configurations compress fluid entering a scroll compressor by sequentially constricting a plurality of compression chambers formed between mutual curls. During the compression process, the fluid generates an axial force that separates the orbiting scroll and the non-orbiting scroll from each other, resulting in the axial separation of the orbiting scroll and the non-orbiting scroll. Leaks will occur after large gaps appear between them. [0003] For scroll compressors with high-pressure exhaust pressure on the motor side, the current technology generally adopted by manufact...
