Abstract

The embodiment of the invention discloses a method and device for detecting the hydraulic pump fault in a hydraulic system. The method includes the steps of detecting the first wheel oil return temperature in a first hydraulic pump and the second shell oil return temperature in a second hydraulic pump when the first hydraulic pump and the second hydraulic pump in the hydraulic system are in the rated work state, and judging whether the fault happens to the first hydraulic pump and / or the second hydraulic pump according to the detected first shell oil return temperature and the second shell oil return temperature. The device comprises a detection unit and a judgment unit. By means of the method, the manpower and maintenance cost of the controllable vibration source hydraulic system can be reduced.

Description

Technical field [0001] This application relates to the technical field of failure detection of geophysical equipment, and in particular to a method and device for detecting failure of a hydraulic pump in a hydraulic system. Background technique [0002] The controllable seismic source mainly uses gas or water to drive the steel plate on the soil or in the water medium to vibrate to generate a wave train with controllable frequency, which becomes the seismic source. As an important seismic wave excitation source, controllable seismic source has the advantages of environmental protection and high efficiency compared with explosive excitation source, so it is widely used in seismic exploration. [0003] As an important part of the controllable seismic source, the hydraulic system needs to provide driving force and seismic wave energy for the controllable seismic source, which makes the structure of the hydraulic system for the controllable seismic source relatively complicated. The h...
