(1) hydraulic system manufacturers to minimize the number of oil pipe fittings and flanges, in the design of a wide selection of superposition valve, cartridge valve, plate valve, the use of integrated block in the form of a reduction of pipeline leakage point is leakproof One of the effective measures.

(2) the hydraulic system in the hydraulic valve installed in the vicinity of the actuator with the place, can greatly shorten the total length of the hydraulic pipe, thereby reducing the number of pipe joints.

(3) hydraulic shock and mechanical vibration directly or indirectly affect the system, resulting in loose pipe joints, resulting in leakage. Hydraulic shocks are often caused by quick commutation. Therefore, in case of conditions permit, as far as possible to extend the commutation time, that is, the spool with a buffer tank, buffer cone structure or in the valve with extended switching time control valve. Hydraulic system should be away from the external vibration source, the pipeline should be a reasonable set of pipe clamp, the pump source can be used shock absorber, high pressure hose, compensation to take over or install pulsation absorber to eliminate pressure pulsation, reduce vibration.

(4) regular inspection, regular maintenance, timely processing is to prevent leakage, reduce the basic guarantee of failure.
