High-pressure pump safe operating procedures

Third, the pump should not work under overload, safety valve pressure to be adjusted according to equipment rated pressure, non-arbitrarily adjusted.

Fourth, ground power, the chassis must be grounded, check the line insulation, before commissioning.

Five, high-pressure pump operation, the oil control valve should be loosen, and then start the pump until the normal operation of empty load, and then close the return valve, gradually screw into the valve stem, increase the load and pay attention to the pressure Table pointer is normal.

Six, the pump stopped working, the valve should be slowly loosen the return valve until the pressure gauge slowly back to zero before the unloading of the pipe jack nut . It is forbidden to change the tubing or pressure gauge during load.

Seven, with the dual-acting jack pump, dual-use oil pump to both oil is appropriate.

Eight, oil-resistant rubber tube must be high pressure, the working pressure shall not exceed the rated oil pump or the actual work of the maximum hydraulic pressure. The tubing length should not be less than 2.5m. When an oil pump drives two jacks, the tubing specifications should be the same.
