High pressure gear pump when using what matters

The correct use of high-pressure gear pump is related to the length of its life, so we understand some of the high pressure gear pump to use some of the considerations is necessary, then now how many people know that high-pressure gear pump in use When to pay attention to what? High pressure gear 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 gauge The pointer is normal. Pumps and jacks to use the provisions of the oil number working oil, generally No. 10 or No. 20 mechanical oil, hydraulic properties can also be similar to other similar oil, such as transformer oil. The oil poured into the tank must be filtered. Frequently used once a month filter, the tank should be cleaned regularly. The tank should generally maintain about 85% of the oil level, should be supplemented in time, the additional oil should be the same as the original pump oil. Oil temperature inside the tank should generally be 10 ~ 40 ℃ is appropriate, should not be used at negative temperature. Tubing under working pressure to avoid bending. The oil tank connected with oil pump and jack should be kept clean. When not in use, it should be blocked with screws to prevent silt from entering. The grease nipple exposed by oil pumps and jacks should be sealed with nuts to prevent dust and debris from entering the machine. After daily use, wipe the oil pump, remove oil grease on the copper wire cloth. Pump should not work under overload, safety valve pressure to be adjusted according to equipment rated pressure, non-arbitrarily adjusted. Ground power, the chassis must be grounded, check the line insulation, before commissioning. With the dual-acting jack pump, dual-use oil pump with two ways at the same time is appropriate. Oil-resistant rubber hose must be high pressure, the working pressure shall not exceed the rated oil pump or the actual maximum working oil 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. Oil pump stop working, the oil return valve should be slowly loosen 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. The above is the high pressure gear pump should pay attention to some of the precautions in the hope that through the understanding of these precautions, follow-up you can better and better use of high pressure gear pump.
