AI Technical Summary

Technical Problem

The existing mud pump monitoring system cannot monitor the performance indicators of mud pumps in real time through multiple sensors, resulting in the inability to conduct risk assessment of mud pumps in a timely, fast and accurate manner, and it is difficult to fully grasp the operating status and risk characteristics of mud pumps from the system level.

Method used

A risk assessment method for the three-frequency fusion of mud pumps is proposed. By monitoring the vibration signal of the mud pump, variational modal decomposition is performed, the arrangement entropy of modal components is extracted, and the SVDD super-sphere model is constructed to realize the risk assessment of the positions of each measurement point of the mud pump to be tested.

Benefits of technology

Real-time comprehensive monitoring of the operating status of the mud pump and rapid and accurate identification of potential risks are achieved, avoiding the problems of incomplete single frequency and inaccurate risk identification in traditional monitoring, improving monitoring accuracy and risk identification capabilities, and ensuring the safe and stable operation of the mud pump.

Abstract

The invention provides a mud pump three-frequency fusion risk assessment method and system and electronic equipment. The method comprises the steps that vibration signals of all measuring point positions in the healthy operation state of a mud pump are monitored; variational mode decomposition is carried out on the vibration signals, mode components are obtained, and permutation entropies of the mode components are extracted to form an evaluation feature vector set; constructing an SVDD hypersphere model based on the evaluation feature vector set; and monitoring operation vibration signals of each measuring point position of the to-be-tested slurry pump in a working state, analyzing the operation vibration signals by adopting the SVDD hypersphere model, and performing risk assessment on each measuring point position of the to-be-tested slurry pump. According to the three-frequency fusion risk assessment method for the slurry pump, the SVDD hypersphere model is constructed on the basis of the vibration signals of all the measuring point positions, the operation vibration signals of all the measuring point positions of the to-be-measured slurry pump are monitored, and real-time comprehensive monitoring of the running state of the slurry pump and rapid and accurate identification of potential risks are achieved.
