1) Minimize the number of oil pipeline joints and flanges as much as possible, and widely use stacked valves, plug-in valves, and plate valves in the design. Adopt integrated block combinations to reduce pipeline leakage points, which is one of the effective measures to prevent leakage.

2) Installing the hydraulic valve station in the hydraulic system closer to the actuator can greatly shorten the total length of the hydraulic pipeline, thereby reducing the number of pipe joints.

3) Hydraulic impact and mechanical vibration directly or indirectly affect the system, causing loosening of pipeline joints and resulting in leakage. Hydraulic shock is often caused by rapid reversing. Therefore, if the working conditions permit, try to extend the reversing time as much as possible, that is, there is a buffer groove, buffer cone structure on the valve core, or a control valve that extends the reversing time is installed inside the valve. The hydraulic system should be kept away from external vibration sources, and pipe clamps should be reasonably set up in the pipeline. The pump source can use shock absorbers, high-pressure rubber hoses, compensation pipes, or install pulsation absorbers to eliminate pressure pulsation and reduce vibration.

4) Regular inspection, maintenance, and timely handling are the most basic guarantees to prevent leaks and reduce malfunctions.
