The leakage of the hydraulic system of the leakage hydraulic cutting machine is divided into internal leakage and external leakage. Internal leakage means that the leakage process occurs inside the system, such as leakage on both sides of the hydraulic cylinder piston, leakage between the control valve spool and the valve body.
Although internal leakage does not cause loss of hydraulic oil, due to leakage, the established control action may be affected until a system failure occurs. An external leak is a leak that occurs between the system and the external environment.
Direct leakage of hydraulic oil into the environment, in addition to affecting the working environment of the system, can also lead to insufficient system pressure to cause failure. There is also a risk of fire from hydraulic oil leaking into the environment.
Solution: Use better quality seals to improve the machining accuracy of the equipment.
