Cross ring fault detection system and method

Abstract

The invention discloses a cross ring fault detection system which comprises magnet parts arranged on end points of a cross ring; sensing parts which are arranged at key slots of a main bracket corresponding to the cross ring, and used for detecting the magnetic field variation generated when the magnet parts slide along the key slots and generating sensing signals; and a controller which is connected with the sensing parts, receives the sensing signals sent by the sensing parts, calculates the rotating speed of a compressor according to the sensing signals, and judges whether the compressor has a fault or not by comparing the rotating speed of the compressor with the message rotating speed. The cross ring detection system has the beneficial effects that a detection device is additionally arranged in the cross ring structure, the problem that fault recognition is difficult to conduct on the cross ring in the prior art is solved, the fault detection and elimination efficiency of the cross ring is improved, the service life of the whole compressor is indirectly prolonged, the working performance of the whole compressor is indirectly improved, and accidents possibly caused by fault operation of the cross ring belt are avoided.

Description

technical field [0001] The invention relates to the technical field of scroll compressors, in particular to an Oldham ring fault detection system and method. Background technique [0002] In the scroll compressor, the Oldham ring is used to fix the movable scroll. When the movable scroll moves eccentrically, the Oldham ring reciprocates in the keyway with the rotation of the movable scroll. During operation, when the Oldham ring is jammed or broken, it is difficult to identify it in a timely and effective manner. If the compressor continues to run, it will further cause problems such as wear and high temperature, resulting in serious damage to the compressor; at the same time, it will also pollute the entire air conditioning system and make it difficult to clean. [0003] In the prior art, the structural strength of the Oldham ring is often improved by optimizing the structure of the Oldham ring or improving the production process, and the failure probability of the Oldham ...

Problems solved by technology

During operation, when the Oldham ring is jammed or broken, it is difficult to identify it in time and effectively

If the compressor continues to run, it will further cause problems such as wear and high temperature, resulting in serious damage to the compressor; at the same time, it will also pollute the entire air conditioning system, making it difficult to clean

[0003] In the existing technology, the structural strength of the cross ring is often improved by optimizing the structure of the cross ring or improving the production process, and the failure probability of the cross ring is reduced, but the technical problem of fault detection for the cross ring is not really solved
