Rapid fault diagnosis method for pump equipment

Abstract

The invention relates to a rapid fault diagnosis method for pump equipment. The rapid fault diagnosis method comprises the following steps that n groups of continuous reference acceleration waveform and speed waveform data are selected when the pump equipment operates normally, and an average value AbAvg of effective values of the n groups of reference acceleration waveforms and an average value VbAvg of effective values of n groups of reference speed waveforms are correspondingly calculated; the current acceleration waveform and speed waveform of the pump equipment are collected, a speed effective value VRms and an acceleration effective value ARms are calculated, and the running state of the pump equipment is judged; and the speed effective value VRms and / or the acceleration effective value Arms are / is analyzed and processed, and the fault reason of the pump equipment is judged. According to the scheme provided by the invention, the fault reason of the pump equipment can be conveniently and timely positioned according to the collected current data and the historical data, so that the accuracy of fault detection is improved, a worker can timely find and solve problems, and the non-planned shutdown loss caused by sudden faults of the pump equipment is reduced.

Description

technical field [0001] The invention relates to the field of machine pump fault diagnosis, in particular to a fast fault diagnosis method for machine pump equipment. Background technique [0002] The state monitoring of machine and pump equipment collects vibration, temperature and other signals of machine and pump equipment, and uses fault diagnosis technology to evaluate the current state of mechanical rotating parts (such as shafts, bearings, gears, etc.), locate the root cause of the fault, and predict the remaining life of the parts , Realize the control of the status of the pump equipment, so that the repair and maintenance work can be arranged reasonably, and the purpose of optimizing spare parts inventory, reducing unplanned downtime, and reducing comprehensive operation and maintenance costs can be achieved. The core of condition monitoring of pump equipment is to extract the core characteristics of the vibration signal, and analyze the type of fault according to it...
