1. Vacuum pump in the process of operation, the bearing temperature can not exceed the ambient temperature of 35C, the maximum temperature shall not exceed 80C.
2. Vacuum pump in the first month of work, replacement of oil by 100 hours, after every 500 hours, oil change time.
3. Regularly adjusting packing gland, packing room of the drip to ensure the normal situation (to drop out as appropriate).
4. Regularly check the wear sleeve, wear in time after a larger replacement.
5. Vacuum pump long-term disabled, need to pump all apart, dry water. The moving parts and combine apply grease to the installed, for safekeeping.
6. Vacuum pump used in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net. To prevent cracking
7. Vacuum pump to stop the use of the first to close the gate valve, pressure gauge, and then stop the motor.
8. Check the oil quality, found that the deterioration of the oil should be timely replacement of oil, to ensure the normal work of the vacuum pump.
9. Under normal circumstances, after vacuum pump working 2000 hours should be maintenance and check Jue rubber seal aging degree, check the exhaust valve is cracking, clean up the dirt on the valve plate and valve seat in precipitation. Clean the parts of the whole vacuum pump cavity, such as rotor, rotary vane, spring, etc.. General gasoline cleaning, and drying. After cleaning the rubber parts with dry cloth to dry. The cleaning assembly should be gently accidentally bumps.
10. Bearing the body to join the bearing lubricating oil, to observe the oil level should be in the standard oil of the center line, the lubricating oil should be replaced or supplemented.
11. Check the vacuum pump pipe and the combination of the loosening of the phenomenon. Rotate the vacuum pump, vacuum pump is flexible look.
12. And anew assembly should conduct a trial run, are generally required to empty operation 2 hours and change the oil twice, for cleaning in vacuum pump will leave a certain amount of volatile matter, to be in normal operation, then put to work.
13. Start the motor, when the normal operation of the vacuum pump, open the export pressure gauge and imported vacuum pumps, as it shows the appropriate pressure, gradually open the valve, and check the motor load.
14. As far as possible to control the vacuum pump flow and head in the sign on the range, to ensure that the vacuum pump at the highest efficiency point of operation, in order to obtain the maximum energy saving effect.
