First, the use of oil pump and jack required oil No. 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.
Second, the tubing under working pressure to avoid bending. Oil pump and jack connected to the fuel tank should be kept clean, do not use the plug when blocked with screws, Park Taibang to prevent sediment into the pump and jack exposed nozzle sealed with nuts to prevent dust, debris into the machine. Daily exhausted, the residue pump should wipe the oil pump, remove the oily copper foil cloth on the grease.
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.
Fifth, before the operation of high-pressured residue pump, the oil control valve should be released, 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 Gauge 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 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.
