Do you know what are the precautions for the use of vacuum pumps in winter? Let's follow the editor of China Rotary vane vacuum pump to have a simple understanding!
1. Do not use in a cold environment.
2. It can be preheated properly before use.
3. Add bearing lubricating oil to the bearing body, observe that the oil level should be at the center line of the oil mark, and the lubricant should be replaced or replenished in time.
4. Close the gate valve, outlet pressure gauge and inlet vacuum gauge of the water outlet pipeline.
5. Jog the motor to see if the rotation direction of the motor is correct.
6. If abnormal sound is found in the vacuum pump, stop and check the cause immediately.
7. Try to control the flow and head of the vacuum pump within the range indicated on the label to ensure that the vacuum pump runs at a higher efficiency point to achieve greater energy-saving effects.
8. Regularly adjust the packing gland to ensure that the leakage in the packing chamber is normal, and it is advisable to leak out as a drip.
9. If the vacuum pump is out of service for a long time, it is necessary to disassemble all the pumps, wipe off the water, coat the rotating parts and joints with grease and install them and keep them properly.
10. Regularly check the wear of the shaft sleeve, and replace it in time when the wear is large.
11. When using in the cold winter, after stopping, unscrew the water drain plug at the bottom of the pump body to drain the medium to prevent freezing and cracking.
12. To stop using the vacuum pump, first close the gate valve and pressure gauge, and then stop the motor.
13. In the first month of work, change the lubricating oil after 100 hours, and then change the oil once every 500 hours.
14. Turn on the motor. When the vacuum pump is running normally, open the outlet pressure gauge and the inlet vacuum pump, and gradually open the gate valve after the proper pressure is displayed. At the same time, check the motor load.
