Due to the various components and pipelines of the hydraulic station during processing and transportation, all kinds of debris such as iron scraps, abrasives, and dust will enter the system before use, so the hydraulic station must be used before it is used for the first time. Lei Mingxin hydraulic engineers suggested that all hydraulic valves, hydraulic oil pumps, and hydraulic equipment should be well-washed and the oil pipes should be cleaned by pickling.

Hydraulic lifting device:
1. Oil leakage and oil pressure instability: After a long period of use, there is a large amount of leakage between the oil collection passages in the safety brake device and between the valve and the oil collection passage, and the oil pressure drop causes the valve to open. Between the screw loosening, the screw can be tightened to eliminate the failure; oil instability is due to the air in the hydraulic system, air should be excluded, or the current of the electro-hydraulic regulator coil is not well filtered, the coil vibrates up and down, causing oil Pressure instability, add electrolytic capacitors to strengthen the filter.
2. The oil pressure value cannot be guaranteed: the reason is that there is air in the system, there is a lot of foam in the oil in the tank, or there is a large leakage in the overflow valve and electromagnetic valve. Processing method: check whether the oil pump inlet leaks; oil pump oil absorption Whether the pipe joint is tightened tightly; whether the screw of the suction filter is tightened; check whether the pipe of the suction filter to the suction port of the oil pump is leaky; check whether the screw of the oil pump cover is tightened; clean the valve core of the overflow valve if the valve core is on the valve. In vivo activities are not flexible, you can use your hand to hold the valve core in the body back and forth grinding; cleaning solenoid valve solenoid valve, requires the valve core in the valve body movement is flexible, to ensure that the valve core in place.
3. Zero oil pressure: The reason why the brake is not released is that there is no pressure in the system: the oil pump rotates in the reverse direction or the oil pump has no output fluid; the overflow valve spool on the electro-hydraulic proportional device is stuck and the orifice is blocked; the oil pump suction port is not open The suction filter is blocked; there is dirt in the pressure valve and the cone valve cannot be closed. Treatment method: Correct the direction of rotation of the pump and eliminate the failure of the oil pump. Open the overflow valve and clean it. It is required to make the valve core move flexibly in the valve body, blow the orifice with compressed air; clean the filter element and check the oil suction tube. If the road is blocked, disassemble the pressure valve and remove the poppet.
4. Excessive residual pressure: Residual residual pressure will cause the brake to lose its function. The main reasons are: the distance between the baffle on the control rod of the electro-hydraulic pressure regulating device and the nozzle is too small; the orifice of the overflow valve is too large. Treatment method: Adjust or replace the upper lever of the control rod; replace the throttle valve orifice of the relief valve with the orifice of smaller diameter.
5. Second-stage brake oil pressure value Pressure-maintaining performance failure: Causes of two-stage brake oil pressure value Pressure-maintaining failures are caused by the presence of dirt in the large relief valve on the oil passage block, which makes the valve core not tightly closed. One-way throttle cut-off valve opening is too large, a large number of oil leakage; electromagnetic valve inside the dirt, the internal leakage is too large. For this type of fault, the valve core can be removed and the dirt can be removed to remove the dirt, so that the valve core is in place, and then the one-way throttle stop valve is adjusted to make the opening as small as possible, which serves to throttle and supplement the oil.
