Abstract

The invention provides a hydraulic pump fault prediction method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining the vibration characteristic data of a hydraulic pump according to the three-axis vibration data of the hydraulic pump; obtaining a fault prediction result of the hydraulic pump according to the vibration characteristic data of the hydraulic pump; wherein the vibration characteristic data comprises time domain characteristic data and frequency domain characteristic data. According to the hydraulic pump fault prediction method and device, the electronic equipment and the storage medium, the vibration characteristic data, obtained based on the three-axis vibration data of the hydraulic pump, of the hydraulic pump serves as the characteristic, the vibration characteristic data of the hydraulic pump is analyzed, the fault prediction result is obtained. According to the method, the possible faults in the future can be predicted before the faults occur, so that engineering technicians can know the use state of the hydraulic pump and the possible faults in advance and reasonably arrange the working period of the hydraulic pump, the hydraulic pump can be overhauled and maintained in time, and the service life of the hydraulic pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a hydraulic pump failure prediction method, device, electronic equipment and storage medium. Background technique [0002] The hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it, and sends it to the actuator. The health status of the hydraulic pump directly affects the installation efficiency of the entire working machine. [0003] In the prior art, temperature or pressure signals are usually used for fault detection of hydraulic pumps. The above signals reflect the state parameters after the hydraulic pump has failed, and can only be used for after-event maintenance, and cannot realize early warning, thus missing Favorable time for troubleshooting. Contents of the invention [0004] The invention provides a hydraulic pump f...
