High-low pressure zone separation mechanism for vortex compressor

Abstract

The isolating support frame of isolating mechanism of high-pressure zone and low-pressure zone of vortex compressor is made into the form of float cylinder, its external circumferential surface is tightly contacted with internal circumferential surface of closed shell body, its upper surface is connected with undersurface of fixed vortex disk and tightly contacted with it by using screw the isolating support frame is equipped with an air-sucking hole whose lower portion is communicated with suction chamber and air-sucking pipe, and its upper portion is communicated with fixed vortex disk and compression cavity of movable vortex disk.

Description

Technical field: [0001] The invention belongs to scroll compressors, in particular to an isolation mechanism for high and low pressure areas of scroll compressors. Background technique: [0002] The scroll compressor has a fixed scroll and a moving scroll, and relies on the relative movement of the fixed scroll and the moving scroll to complete the compression. Because of its high efficiency, low noise, small size and light weight, it is widely used in indoor air conditioners. And automotive air conditioners are widely used, full of practicability. [0003] The structure and working conditions of the traditional scroll compressor are as follows: figure 1 An explanatory diagram of the brief structure of a traditional scroll compressor, in figure 1 Among them, the internal fluid does not flow out, and the airtight casing 15 that maintains a certain pressure inside; the suction pipe 1 and the suction chamber 4 for the fluid to flow in from the outside; the fixed scroll 8 and ...

AI Technical Summary

Problems solved by technology

[0013] In this connection method, the thermal deformation of the upper partition 12 itself generated during the welding process of the upper partition 12 and the airtight casing 15 is transmitted by the fixed scroll through the connecting bolt 12a, so that the position of the fixed sheet 8a is consistent with the original design. Differences in position cause installation errors in the installation positions of the rotating sheet 7a and the fixed sheet 8a

[0014] The disadvantage of the traditional scroll compressor is: the installation error of the rotating sheet 7a and the fixed sheet 8a causes fluid leakage during the process of fluid compression, which is the cause of poor performance of the compressor
