The hydraulic system leakage of the hydraulic cylinder manufacturer can be divided into internal leakage and external leakage according to the flow direction. External leakage mainly refers to the leakage of hydraulic oil from the system to the environment, which is generated outside the hydraulic pipeline, hydraulic valve, hydraulic cylinder and hydraulic pump (hydraulic motor) of the hydraulic system; Internal leakage refers to the existence of pressure difference between high and low pressure sides and the failure of sealing elements

How to select the hydraulic oil type of the cylinder manufacturer 1. Select according to the working pressure of the hydraulic system. Different working pressures have different requirements on the quality of hydraulic oil. With the increase of system working pressure, the anti-wear, anti-oxidation, anti foam, anti emulsification, hydrolysis stability and other properties of hydraulic oil should also be improved. At the same time, in order to prevent leakage caused by pressure increase, the hydraulic oil is sticky
