1. Routine inspections before the operation of the hydraulic system carefully check whether the system leaks, whether the connection is loose, whether the piston rod and hydraulic hose are bruised, whether the low-pressure oil inlet pipe of the hydraulic pump is connected reliably, whether the oil level of the fuel tank is correct, and the main electromagnetic of all motion mechanisms Whether the valve is in the original state, etc., to ensure that the hydraulic system and equipment are in good technical condition. Atmospheric fuel tanks should also check and clean the fuel tank vents to keep them unobstructed to prevent the vents from clogging and causing the fuel tank to vacuum, which would make the hydraulic pump difficult to suck and damage.
2. The patrol inspection during the operation of the hydraulic system should regularly check the joints and sealing devices between the pipelines and components. The failed sealing devices should be replaced in time, and the pipe joints (and bolts on each joint surface should be tightened. By looking, smelling, listening, Check the operating conditions of the system and equipment from time to time. If there are abnormal phenomena such as noise, pressure fluctuation, leakage, vibration, etc., analyze the cause and deal with it in time to eliminate potential safety hazards. Pay attention to hydraulic pumps at all times. If the hydraulic pump has cavitation noise that cannot be eliminated after exhaust, it should be used after finding the cause and troubleshooting. If a certain actuator moves slowly when there is no load, and the overflow valve overflows If there is a sound flow, it should be shut down immediately for maintenance.
3. The daily maintenance of the hydraulic system is strictly in accordance with the requirements of the equipment maintenance manual. The oil-resistant rubber bands and filter elements that are easy to wear and age are replaced in time to reduce pipeline leakage and prevent pressure loss; frequently activate the moving parts of the actuator to prevent rust Reduce running resistance; regularly use the same brand of hydraulic oil to clean the pipelines, fuel tanks, filters, etc.
