Abstract

The invention is suitable for the technical field of hydraulic pumps, and provides a method and a device for predicting the remaining service life of a hydraulic pump and terminal equipment. The method comprises the steps of acquiring vibration data and oil return flow data of the hydraulic pump; calculating a health state index of the hydraulic pump according to the vibration data and the oil return flow data; inputting the health state index into a pre-established hydraulic pump health state prediction model to obtain a health state prediction curve of the hydraulic pump; and determining the remaining service life of the hydraulic pump according to the health state prediction curve. According to the method and the device for predicting the remaining service life of the hydraulic pump and the terminal equipment provided by the invention, the remaining service life of the hydraulic pump can be accurately predicted.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pumps, and in particular relates to a hydraulic pump remaining service life prediction method, device and terminal equipment. Background technique [0002] Accurately and scientifically predicting the remaining service life of the hydraulic pump is conducive to maintenance according to the state of the hydraulic pump, and is of great significance to ensure the reliability and safety of the hydraulic pump. [0003] However, due to the harsh operating environment and complex degradation mechanism of the hydraulic pump, the sensor information from a single source is not enough to accurately reflect the degradation process of the hydraulic pump, which is not conducive to the accurate prediction of the remaining service life of the hydraulic pump. There is an urgent need in the art for a method to accurately predict the remaining service life of a hydraulic pump. Contents of the invention [0004]...
