Abstract

The invention relates to a centrifugal compressor torque monitoring device, and relates to the technical field of structural design of centrifugal compressor safety maintaining machines. The device isused for monitoring torque changes of a rotor of a centrifugal compressor, a torque indexing disc is arranged at the positions, close to the two ends of a spindle, of the spindle in a sleeving manner, grooves are formed in the circumferential direction of the torque indexing disc in an equal-angle spaced manner, a phase probe and the torque indexing disc are arranged on a machine shell in a matching manner, the phase probe is used for detecting torque changes of the torque indexing disc and generating first signals, a toque analysis device is electrically connected with the phase probe, usedfor receiving and calculating and analyzing a first signal, obtaining torque and the rotating sped of the rotor of the centrifugal compressor and obtaining power of the centrifugal compressor according to the torque and the rotating speed. Through power changes, responsibility equipment with the torque change is obtained, it can be distinguished that the power is changed due to the drive device failure or the failure of a certain compressor, and accurate data information is provided for maintaining of the responsibility equipment by a decision maker at the first time.

Description

technical field [0001] The invention relates to the technical field of structural design of a centrifugal compressor safety maintenance machine, in particular to a torque monitoring device for a centrifugal compressor. Background technique [0002] With the continuous and rapid development of industry, nuclear power, petrochemical, pharmaceutical, food and other industries at home and abroad are equipped with centrifugal compressors to realize their production process. In each of the above-mentioned processes, the medium of some centrifugal compressors is gas. Due to the unique flow characteristics of the above-mentioned gas medium, the flow rate of the gas will fluctuate during the process, resulting in fluctuations in the outlet pressure of the centrifugal compressor. As a result, the power of the entire centrifugal compressor fluctuates greatly, and the power of the unit increases, resulting in a decrease in the working efficiency of the centrifugal compressor. When the ...
