Liquid ring vacuum pump complete with motor

Liquid ring vacuum pump is a kind of crude vacuum pump, with the development of economy and technology, the application of liquid ring vacuum pump is more and more wide, in the vacuum filtration, vacuum water, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture and vacuum degassing and other industrial production process play an important role; In addition, it also has the characteristics of compact structure, reliable work balance, even flow, but in the efficiency, the liquid ring vacuum pump is relatively low, and this is mainly due to the impeller in the process of stirring liquid loss of a large amount of energy. The following for you to introduce the liquid ring vacuum pump with motor maintenance steps.

Liquid ring vacuum pump of maintenance

1. Regularly add bearing oil or butter into the bearing body of liquid ring vacuum pump

2. When using the liquid ring vacuum pump, first unscrew the water inlet plug of the pump body of the vacuum pump and pour the water inlet. In particular, the mechanical seal of the water ring vacuum pump (2BV,2BE) restart the motor

3. Close the gate valve of the outlet pipeline, the outlet pressure gauge and the inlet vacuum gauge

4. Start the motor and check whether the motor turns correctly

5. Start the motor. When the vacuum pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump

6, try to control the flow of the vacuum pump and the vacuum degree in the range indicated on the label, to ensure that the vacuum pump in a higher efficiency point of operation, to achieve greater energy saving effect

7. During the operation of the liquid ring vacuum pump, the bearing temperature shall not exceed the ambient temperature of 35C, and the higher temperature shall not exceed 80C

8. If abnormal sound is found in the liquid ring vacuum pump, stop and check the reason immediately

9, the vacuum pump to stop the use, first close the gate valve, pressure gauge, and then stop the motor

10, the liquid ring vacuum pump in a month of work, after 100 hours to replace the lubricating oil, after each 500 hours, oil change once

11. Adjust the packing gland frequently to ensure the normal dripping and leaking condition in the packing room (it is advisable to drip and leak out)

12, regularly check the wear of the shaft sleeve, wear should be replaced in time

13, the vacuum pump in the winter season to use, after stopping, the lower part of the vacuum pump body water screw screw will put the medium. To prevent the frost crack

14. When the liquid ring vacuum pump is out of service for a long time, it is necessary to disassemble the pump, dry the water, coat the rotating part and the joint with grease and put it in place for safekeeping
