Abstract

The invention discloses data acquisition equipment for compressor vibration testing and an acquisition method thereof.The data acquisition equipment comprises a testing box, a compressor body, a first sensor signal line, a first shielding signal line, a second sensor signal line, a second shielding signal line and a connecting line, and sliding grooves are formed in the side walls of the two ends in the testing box; and a sliding block is arranged in the sliding groove, a supporting plate is installed at the end, away from the sliding groove, of the sliding block, a fixing plate is arranged at the top end of the supporting plate, a compressor body is installed at the top end of the fixing plate, and fixing frames are installed at the four corners of the top end of the supporting plate correspondingly. According to the invention, through mutual clamping of the clamping block and the clamping groove, one end of the mounting plate is enabled to rotate, and the clamping block is not clamped with the clamping groove, so that an operator can conveniently mount and dismount the fixing plate and the compressor main body by pressing the mounting plate, and the compressor is prevented from toppling over during a vibration test, which influences the vibration test effect of the compressor.

Description

technical field [0001] The invention relates to the technical field of compressor vibration testing, in particular to a data acquisition device for compressor vibration testing and a collection method thereof. Background technique [0002] A compressor is a driven fluid machine that lifts low-pressure gas into high-pressure gas, and is the heart of a refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. The compressor is regarded as a refrigeration system. The special term that can best express the characteristics of the compressor is called "vapor pump". The actual responsibility of the compressor is to increase the pressure and increase the suction pressure state to the exhaust pressure state; [0003] The compressor wil...
