1. Check the vacuum pump pipeline and joint for looseness.
2. Add the bearing lubricating oil into the bearing body, observe that the oil level should be at the center line of the oil mark, and the lubricating oil should be replaced or supplemented in time.
3. Screw off the water diversion plug of the vacuum pump body to inject water or slurry.
4. Close the gate valve of water outlet pipeline, outlet pressure gauge and inlet vacuum gauge.
5. Start the motor. After the vacuum pump operates normally, open the outlet pressure gauge and the inlet vacuum pump. Gradually open the gate valve to check the load of the motor after it shows the appropriate pressure.
6. Control the flow and head of the vacuum pump as far as possible within the range indicated on the label to ensure that the vacuum pump operates at the highest efficiency point to obtain the maximum energy-saving effect. 7. During the operation of vacuum pump, the bearing temperature shall not exceed the ambient temperature by 35 ℃, and the maximum temperature shall not exceed 80 ℃.
8. When the vacuum pump stops using, close the gate valve and pressure gauge first, and then stop the motor.
9. In the first month of operation, the lubricating oil of vacuum pump should be changed within 100 hours, and then it can be changed every 500 hours.
10. Adjust the packing gland frequently to ensure that the leakage in the packing chamber is normal, and it is appropriate to let the drip leak out.
The wear of the shaft sleeve should be checked regularly.
12. When the vacuum pump is used in the cold winter season, it is necessary to screw off the drain plug at the lower part of the pump body to drain the medium completely.
