Oil Change Processing of Vacuum PumpBecause chemical or pharmaceutical process gases will contain inflammable, explosive and corrosive gases to varying degrees, which is why dry vacuum pumps need special treatment for us. For the simple internal structure of dry screw vacuum pump, two rotors and pump chambers should also pay attention to anti-corrosion treatment. At this time, we should also pay attention to the choice of nickel-phosphorus coating and Teflon coating.Claw vacuum pump is more difficult to do anti-corrosion treatment, there is almost no way to do surface treatment between all levels of partitions, and the anti-corrosion coating on the rotor surface is relatively easy to assemble without damage. Oil-free scroll vacuum pump is only suitable for pumping clean gas, at this time it is not possible to extract flammable, explosive and corrosive gases.When it comes to oil exchange of vacuum pump equipment, we should pay attention to oil exchange once after three months to six months of continuous operation. In humid areas, pumps working in wet season or polluted by pumped gases are very polluted. To a large extent, that is to say. Attention should be paid to shortening the oil exchange time according to the specific situation.When the vacuum pump equipment is changing oil, first of all, we should pay attention to dismantling the vacuum system, and then we should pad one end of the chassis motor higher, open the oil plug to drain oil, turn the vacuum pump, cover the exhaust port, so that all the dirty oil in the cavity is discharged from the oil outlet, and then add new oil 100-500ML from the air inlet to continuously rotate 5-10. Turn to the above for internal cleaning, according to this operation 3-5 times, after the special dirty oil is cleared, then install the oil plug, put the pump flat, add new oil from the intake and the filling hole respectively, and the oil change will be completed.Vacuum pump equipment should not start motor for a long time when changing oil, which will make the exhaust valve piece jump too intensely and fatigue; the oil exchange of vacuum pump equipment should also be strictly prohibited using kerosene, gasoline, alcohol and other non-disassembly cleaning of the pump; if the shutdown time is longer, we should pay attention to taking off the exhaust gas. Put the exhaust plug on the cover, close the intake, and drain the accumulated water.
