Abstract

The invention relates to the field of engineering machinery, and provides a hydraulic pump fault detection method and device and an operation machine.The method comprises the steps that real-time electric energy data consumed by a to-be-detected hydraulic pump within a preset duration are obtained; and determining the damage degree of the to-be-tested hydraulic pump based on the comparison result of the real-time electric energy data and the electric energy standard value. According to the method, the real-time electric energy data consumed by the to-be-tested hydraulic pump within the preset duration are obtained, the real-time electric energy data are compared with the electric energy standard value, and the damage degree of the to-be-tested hydraulic pump can be accurately determined in real time according to the comparison result.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a hydraulic pump fault detection method, device and working machinery. Background technique [0002] With the popularization of charging and power exchange facilities and the maturity of battery, motor, electronic control, and charging / power exchange technology, the electrification of construction machinery is the general trend, and more and more hydraulic pumps will be driven by electricity. Because construction machinery usually works in harsh environments, hydraulic pump failures occur frequently, which greatly reduces construction efficiency. [0003] At present, the faults of hydraulic pumps during the operation of construction machinery are usually judged by human experience, or dealt with after failures occur. The detection efficiency is low, and the degree of damage to the hydraulic pumps cannot be accurately predicted, making it difficult to meet the const...
