General classification of hydraulic system failures
source:Industry News release time:2022-03-19 Article author:Rosit Popular:Air band saw
The hydraulic system is mainly used for work, freeing hands and making work easier. Identifying the cause of the failure of the hydraulic system is the most important and difficult part of troubleshooting, especially for junior hydraulic technicians. As a hydraulic wrench manufacturer, you need to understand the working principle of the hydraulic system and understand the failure of the hydraulic system in order to effectively solve the problem.
Hydraulic system failures can be roughly divided into three categories:
Abnormal pressure: Generally, many pressure measuring points are reserved in the design of hydraulic system pipelines. The pressure gauge can be used to monitor and measure the readings of the detection points, and the hydraulic components that cause the abnormal pressure can be determined by comparing and analyzing with the normal value.
Abnormal speed: Adjust each throttle valve, speed control valve and variable pump variable mechanism one by one according to the drawings, and compare and analyze the speed range value of the actuator with the design value.
Abnormal action: switch each reversing valve, observe whether the action state of the relevant actuator is normal, you can find out the abnormal reversing valve, and then check the action sequence and stroke control to find out the abnormality.
