What Are The Vacuum Pump Maintenance Tips

- Nov 08, 2017-

1. Often check the oil level position, do not meet the requirements must be adjusted to meet the requirements. When the vacuum pump is running, the oil level is at the center of the oil mark.

2. The oil change period according to the actual use conditions and can meet the performance requirements and other circumstances, by the user discretion. General new vacuum pump, pumping clean and dry gas, it is recommended to change oil at about 100 hours. When the ferrous metal powder is not visible in the oil, the oil change period can be extended appropriately.

3. Often check the oil quality, found that the oil deterioration should be timely replacement of new oil, to ensure that the vacuum pump work properly.

4. the vacuum pump in the first month of work, after 100 hours to replace the lubricating oil, then every 500 hours, oil change once.

5. In general, the vacuum pump after 2000 hours of work should be carried out maintenance, inspection Jue rubber seal aging degree, check the exhaust valve is cracking, clean up the precipitate in the valve and exhaust valve seat on the dirt. Cleaning the parts in the whole vacuum pump, such as rotor, rotating disc, spring, etc.. Usually cleaned with gasoline and dried. After cleaning the rubber parts, dry it with dry cloth.  Cleaning and assembling should be handled with care and hurt easily.

6. Add lubricating oil into bearing body, observe the oil level at the centerline of the oil mark, and replace or supplement the lubricating oil in time.

7. Check the vacuum pump pipeline and joint loose or not.  Turn the vacuum pump by hand and see if the vacuum pump is flexible.

8. After re assembly, should be tested, usually empty operation 2 hours and change oil two times, because the cleaning in the vacuum pump will remain a certain amount of volatile matter, after normal operation, and then put into normal work.

9. Start the motor, when the vacuum pump after normal operation, open the outlet pressure gauge and import vacuum pump, as it shows the appropriate pressure, gradually open the gate valve, and check the motor load situation.

10. As far as possible to control the flow and head of the vacuum pump in the mark marked range, in order to ensure the vacuum pump in the highest efficiency point operation, to obtain the maximum energy saving effect.

11. To stop the use of vacuum pumps, first shut the gate valve, pressure gauge, and then stop the motor.

12. The vacuum pump in the operation process, bearing temperature can not exceed the ambient temperature 35C, the maximum temperature shall not exceed 80C.

13. The vacuum pump in the first month of work, after 100 hours to replace the lubricating oil, then every 500 hours, oil change once.

14. Often adjust the packing gland, to ensure that the filling room leakage is normal (in order to drop leakage is appropriate). Regular inspection of shaft sleeve wear, wear larger, should be replaced in time.

15. Vacuum pump long-term stop, need to pump all open, dry moisture, the rotating parts and the combination of grease coated, safekeeping. Vacuum pump used in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net to prevent cracking.
