Many users use the rules for hydraulic gear pumps. Because the correct operation of the hydraulic gear pump not only hydraulic gear pump efficiency, extend its service life and avoid accidents, so understand the relevant hydraulic gear pump safety rules of operation is particularly important. Interpretation of the rules of safe operation of hydraulic gear pump 1. Grounding power supply, the chassis must be grounded, check the line insulation, before commissioning. 2. High-pressure gear pump before operation, the oil control Valve should be loosen, and then start the gear pump until the normal operation of empty load, and then close the return valve, gradually screw into the valve stem, increase the load and Note pressure gauge pointer is normal. 3. Gear pump stop working, the oil return valve should be slowly loosen until the pressure gauge slowly back to zero before lifting the jack pipe nipple. It is forbidden to change the tubing or pressure gauge during load. 4. With dual-acting jack pump gear to use two simultaneous oil transmission double gear pump is appropriate. 5. Oil-resistant rubber tube must be high pressure, working pressure shall not exceed the rated oil pressure gear or the actual work of the maximum hydraulic pressure. The tubing length should not be less than 2.5m. When a gear pump driven two jacks, tubing specifications should be consistent. 6. Gear 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. 7. Tubing under working pressure to avoid bending. Connect the gear oil pump and jack of the fuel tank should be kept clean, do not plug it with screws, to prevent sediment into the gear pump and jack exposed nozzle to be sealed with nuts to prevent dust and debris into the machine. Daily run out, the gear pump should be wiped clean oil grease on the silk cloth on the grease. 8. gear pump should not work under overload, safety valve pressure to be adjusted according to equipment rated pressure, non-arbitrarily adjusted. The above is the basic rules of hydraulic gear pump safe operation, the user should be as far as possible in accordance with the rules of the specific operation of the process, so that hydraulic gear pump can play a greater role.
