1. Check whether the vacuum pipe and the junction loosening. Hand rotation vacuum pumps, vacuum pump If we look at whether the flexibility. 2. To join the bearing lubrication oil bearing the body to observe the oil level should be the subject of the centerline at the oil, lubricating oil should be promptly replaced or supplemented. 3. Screw vacuum pump under the water pump drain plug, filling water or arguments pulp. 4. Off the road a good outlet pipe valve and exports and imports vacuum gauge manometer. 5. Jog motor, If we look at motor turn is correct. 6. Activate the motor, when the normal operation of vacuum pump, open the export and import of vacuum pressure gauge, depending on its display, after the appropriate pressure, and gradually open the valve, and check the motor load conditions. 7. Try to control the flow of vacuum pump and the lift on the plate within the scope specified in order to ensure the efficiency of vacuum at the highest point of operation in order to get the most energy-saving effect. 8. Vacuum pump during operation, the bearing temperature must not exceed the ambient temperature 35 ℃, the maximum temperature not exceeding 80 ℃. 9. If found to have abnormal noise vacuum pump should be immediately stopped and check the reason. 10. Vacuum pump to stop when it is used to close the valve, pressure gauge, and then stop the motor. 11. Vacuum pump at work, within the first month, after 100 hours to replace oil, after every 500 hours, oil change time. 12. Regularly adjusting packing gland, packing the room to ensure drip drip out of the situation to normal in order to become suitable.. 13. Periodic inspection sleeve wear, the wear should be promptly replaced after larger. 14. Vacuum pump used in the winter season, parking, the need to turn on the water pump drain plug screw to open the lower part of the media put the net. Prevention of Frost Crack. 15. Vacuum pump long-term disabled, the need to pump all apart and wipe away moisture, and the combination of the rotating parts coated with grease installed at a good, safe custody.
