Health Evaluation Method for Unit of Multi-sand Water Pumping Station

Abstract

The progress of science and technology has provided strong support for water conservancy modernization. The development of modern water conservancy has put forward new standards and new requirements for the intelligent management of pumping stations. The overhaul management is no longer satisfied with the traditional maintenance mode of the combination of planned maintenance and corrective maintenance. The multi-sand water pumping station unit health evaluation system can effectively evaluate the overall safety level of the pumping station system, and timely find and eliminate equipment hidden dangers. Maintenance provides significant decision support and provides a new type of predictive maintenance mode for the pumping station, which greatly improves the safety and reliability of the unit operation. The pump health status evaluation model is built from the top to the bottom according to the level. Through the analysis of the unit's vibration, swing, temperature, electrical quantity and other indicators, through the end evaluation price standard, the current status of the equipment is evaluated in real time, then push the real-time evaluation status of the current device to the upper layer according to the recursive logic. Combined with the unit fault diagnosis results, the health evaluation results of the pump station units are obtained through priority comparison.
