How to change the oil of the vacuum pump equipment?
Jun 03, 2019| We all know that vacuum pumps need to be changed regularly during use. How do you change the oil for vacuum pump equipment? The small series is very stable and simple for you.
Because chemical or pharmaceutical related process gases contain varying degrees of flammable, explosive, and corrosive gases, it is precisely because of this that dry vacuum pumps require special handling for us. For the dry screw vacuum pump, the internal structure is simple, and the two rotors and pump chambers should be treated with anti-corrosion treatment. At this time, it is necessary to pay attention to the nickel-phosphorus coating and Teflon coating.
The claw type vacuum pump is more difficult to handle the anti-corrosion treatment. There is almost no way to do the surface treatment between the separators at all levels, and the anti-corrosion coating on the surface of the rotor is relatively easy to be damaged during assembly. The 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 the oil change of the vacuum pump equipment, after the vacuum pump equipment is in continuous operation for three to six months, it is necessary to pay attention to the oil change once, the area where the humidity is relatively large, the pump working in the wet season, or the pumped gas. If there is a lot of pollution, as far as this is concerned, it is to a large extent that it is necessary to pay attention to shortening the oil change time according to the specific situation.
Vacuum pump equipment should first pay attention to remove the vacuum system when the oil is changed. After that, the bottom of the chassis motor should be raised higher. Open the drain plug to drain the oil, turn the vacuum pump, and clamp the exhaust port to make the cavity. All the slop oil is discharged from the oil discharge port, and then 100-500ML of new oil is added from the air inlet to continuously rotate 5-10 rpm. For internal cleaning, follow this operation 3-5 times, after the special oil is cleared, reload Put the oil plug on, put the pump flat, add new oil from the air inlet and the fuel hole respectively, and change the oil.
Vacuum pump equipment should not be used to drive the motor for a long time when changing oil. At this time, the exhaust valve flap will be too vigorous and fatigued. For oil change of vacuum pump equipment, it is also forbidden to use kerosene, gasoline, alcohol, etc. for non-disassembly of the pump. Cleaning; if the pump stop time is relatively long, you should pay attention to remove the exhaust hood and put the exhaust plug, close the air inlet, and drain the water.
