Avoid hydraulic oil pollution caused hydraulic system overheating

Avoid hydraulic oil pollution. The impurity in the oil will aggravate the wear of the friction surface and cause the temperature rise. Too high oil temperature can easily cause hydraulic oil deterioration, resulting in lax sealing of safety valve, resulting in overflow loss. If hydraulic oil viscosity decline, oil failure, should be replaced in time. Combined with the working environment, the oil exchange cycle of the oil used to replace the hydraulic oil regularly. Replace the filter element at the same time. The selected oil should be tested before oil change, and oil pollution should be prevented during the replacement process. When changing oil, the hydraulic pump should be started after the oil is added to the marking line, so that the oil can be fully lubricated to the system.
