Basic principles to be followed when a fault occurs in a hydraulic system

(1) Master the types of faults and conduct comprehensive analysis. According to the final phenomenon of faults, gradually find out a variety of direct or indirect possible causes. In order to avoid blindness, comprehensive analysis and logical judgment must be carried out according to the basic principles of the system to reduce the approximation of suspected objects and finally find out the fault location.

(2) Fault diagnosis is based on operation records and some system parameters. Establish the system operation record, which is the scientific basis for the prevention, detection and treatment of faults; The establishment of equipment operating fault analysis table, which is the height of the use of experience summary, help to make a quick judgment on the fault phenomenon; With certain detection means, the fault can be made accurate quantitative analysis.

(3) To determine the working conditions of the hydraulic system and the surrounding environment is normal, we need to figure out whether the mechanical part of the equipment or the electrical control part of the fault, or the fault of the hydraulic system itself, and find out whether the various conditions of the hydraulic system meet the requirements of normal operation.

(4) When verifying the possible cause of a fault, it is generally necessary to start from the most likely cause of the fault or the place that is easiest to verify, so as to reduce the workload of assembly and disassembly and improve the speed of diagnosis.

(5) Regional judgment Determine the area related to the fault according to the fault phenomenon and characteristics, gradually reduce the scope of the fault, detect the components in the area, analyze the cause, and finally find out the specific location of the fault.

The above is the electromechanical hydraulic system manufacturer - Haopurui hydraulic to share on the hydraulic system failure should follow the basic principles!
