The invention provides a water pump remaining service life prediction method and device, equipment and a storage medium, and relates to the technical field of industrial equipment maintenance. The method comprises the steps of collecting vibration information, pressure value information and water pump flow value information of a water pump; performing time-frequency domain information extraction on the vibration information, and constructing a feature set of the water pump; and performing data dimension reduction on the feature set, predicting the feature set after dimension reduction, and determining the remaining service life of the water pump. The invention comprises that various information of the water pump during operation is obtained, and features of the water pump are extracted through a preset prediction model for prediction. Various operation data of the water pump are fully considered, and the prediction result is more accurate. And time-frequency domain information is extracted from vibration information, and input is constructed with water pump inlet and outlet pressure and a water pump fluid flow value, so that service life prediction is more accurate. The accuracy of predicting the residual life of the water pump is guaranteed, maintenance personnel can maintain or replace the water pump conveniently, and the production safety is improved.
Description
technical field [0001] The present application relates to the technical field of industrial equipment maintenance. Specifically, the present application relates to a method, device, equipment and storage medium for predicting the remaining service life of a water pump. Background technique [0002] With the rapid development of my country's economy, the consumption of residential water and industrial water is increasing year by year, and the stable operation of water pumps in water companies is particularly important. Predicting the remaining service life of the water pump has very important engineering value for subsequent maintenance work. [0003] In the existing technical solutions for predicting the remaining service life of water pumps, only individual types of data during pump operation are collected, and comprehensive information of the pump cannot be obtained, which will affect the accuracy of remaining service life prediction, resulting in inaccurate prediction of ...
