1. hydraulic pipeline oil leakage 1. The quality of the hydraulic pipeline is not up to standard. The quality of the hydraulic pipeline is not up to standard, the pressure bearing capacity is low, and the use time is short, and oil leakage is prone to occur. For iron oil pipes, the thickness of the pipe wall is uneven, which makes the oil pipe The carrying capacity is reduced; for hoses...

1. The resistance hole is blocked. For the relief valve of hydraulic press, the pressure is often lost after the system is pressed, and the pressure cannot be adjusted by rotating the handwheel. Or the system overpressure, overflow valve does not play the role of overflow. for hydraulic pressure reducing valve is shown as the outlet pressure can not go, oil...

1. The hydraulic speed control valve cannot be used in reverse, otherwise the differential pressure reducing valve cannot be used as a pressure compensator. 2. In order to ensure the normal operation of the hydraulic speed control valve, it should be noted that the working pressure difference of the speed control valve should be greater than the smaller pressure difference of the valve. high pressure speed control valve of more...

(1) The valve plug of the 100-ton single-arm hydraulic press is stuck or the valve hole is blocked. When the flow valve or directional valve spool is stuck or the valve hole is blocked, the hydraulic cylinder is prone to failure or failure. In this case, check for oil contamination; check for dirt or colloidal deposits...
