A flexible scroll compressor with over-high pressure and fluorine-deficiency protection

Abstract

The invention discloses a scroll compressor. The scroll compressor comprises an outer shell, a supporting frame, a compression mechanism, an Euclidean ring, an insulating and spacing plate as well as a flexible structure, wherein the supporting frame is fixed in the outer shell, and comprises a main supporting frame and an auxiliary supporting frame; the compression mechanism is supported in the supporting frame and comprises a second scroll plate constructional element and a first scroll plate constructional element which are connected in a meshed mode; the Euclidean ring is combined with the second scroll plate constructional element and the first scroll plate constructional element so as to prevent the relative rotation between the second scroll plate constructional element and the first scroll plate constructional element; the insulating and spacing plate comprises a pressure discharge element which is connected with a high-pressure cavity and a low-pressure cavity; the flexible structure is arranged between the supporting frame and the first scroll plate constructional element. The scroll compressor provided by the invention is applied to different types of scroll and rotary compressors, has favorable automatically-regulating and scroll protection functions, and can release gases from the high-pressure side to the low-pressure side under the ultra-pressure or fluorine-free running condition, so that moving plate mechanisms and static plate mechanisms are protected from being damaged.

Description

technical field [0001] The present invention relates to a scroll compressor, more specifically, the present invention relates to a scroll compressor that releases gas from the high pressure side to the low pressure side under the condition of overpressure or lack of fluorine, so as to protect the moving disk and the static disk mechanism from damage. machine. Background technique [0002] In the refrigeration system, when the pipeline is blocked and the refrigerator leaks, the scroll compressor will have ultra-high back pressure or fluorine-deficient operation, which will cause the mechanism such as the second scroll and the first scroll to fail. Abnormal high pressure or high temperature causes wear or rupture, which accounts for the majority of compressor failures. Measures generally adopted in the refrigeration industry: 1. One is to install a high-pressure pressure sensor and a low-pressure pressure sensor in the refrigeration pipeline on the suction and discharge sides...

AI Technical Summary

Problems solved by technology

Although this structure can achieve flexible adjustment in the axial direction, the method of fixing the hollow guide post and screws makes the assembly complex and requires high precision, and the large gap between the hollow guide post and the first scroll also causes greater vibration and vibration. noise
