Analysis of Common Faults in Hydraulic System of Cutting Machine

1, fever

Due to the difference in the flow velocity of the various parts of the transmission medium during the flow process, there are different degrees of internal friction inside! An increase in temperature may cause the occurrence of internal and external leakage, which may reduce the efficiency. However, a higher temperature may cause an increase in the internal pressure of the expansion of the hydraulic oil, so that the control action cannot be well transmitted.


(1) use high quality hydraulic oil

(2) Layout of hydraulic piping should avoid elbows

(3) Use better fittings and joint hydraulic valves! Fever is an inherent feature of the hydraulic system that cannot be eradicated.

2, leakage

The leakage of the hydraulic system is divided into two types: internal leakage and external leakage. Internal leakage refers to leakage inside the system, such as leaks on both sides of the piston and between the valve plug and the valve body. External leakage refers to a leak that occurs in the external environment.


(1) Check if the pipe joint is loose

(2) Use good quality seals.
