A swash plate compressor speed measuring device

Abstract

The invention discloses a swash plate type compressor speed measuring device, which is installed on a compressor provided with a pump body, a main shaft, and a swash plate fixed on the main shaft. 1. Magnetic sensor, the two symmetrical ends of the swash plate are provided with magnetized area 1 and magnetized area 2 with opposite polarities generated by the magnetization machine, and the magnetized area 1 and magnetized area 2 include the front side of the magnetized end on the swash plate , the back and the side connecting the front and the back, the cross-sections of the magnetized area 1 and the magnetized area 2 are both rectangular, the compressor is installed on the front of the mounting seat, and on the back of the mounting seat on the concentric circle with the center of the mounting seat as the center. There are multiple blind holes for installation, and the center of the concentric circles is on the same straight line as the center line of the main shaft. The solution provided by the invention can greatly improve the detection accuracy while not increasing the occupied space in the car body, and can be integrated into the market faster.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a speed measuring device for a swash plate compressor. Background technique [0002] In the automobile air-conditioning refrigeration system, two-way piston swash plate and variable displacement swash plate compressors are widely used. When the compressor is working, whether the compressor's speed is normal or not has a crucial impact on the refrigeration system. The traditional compressor does not have an effective speed measuring device, and cannot directly and effectively detect the speed of the main shaft swash plate system. Once the speed of the main shaft swash plate is inconsistent with the set speed, it will easily lead to equipment failure and equipment damage. The service life of the air conditioner is reduced, and the cost of use, replacement and maintenance is high, and the air conditioning and refrigeration system cannot operate normally, which seriously affects ...

Problems solved by technology

However, this technology is a destructive construction on the side of the swash plate. The induction element is fixedly installed in the swash plate, and the speed measuring element is installed in the shell. The installation process will damage the structure of the shell and the swash plate, which will inevitably cause The problem of reducing the strength of the shell and the strength of the swash plate will also cause the structural imbalance of the swash plate, which will affect the working efficiency of the compressor, and seriously cause the compressor to stop working
