Hydraulic equipment may be used for a long time or in some incorrect ways, which will affect some faults in the later period. How to discharge them in case of faults?
First of all, we should observe the cause of the failure. The source of the problem can be observed in the state after the failure. We can use experience to calculate the cause after the failure.
2. It is very important to analyze the working principle of hydraulic equipment. In normal times, you can learn more about some theoretical knowledge related to hydraulic equipment and be familiar with the use of each part.
3. You can use the method of elimination to diagnose the machine and check whether the parts of the machine have any faults. You can try to use the method of elimination.
