Water ring pump operation

The performance of water ring pump is more stable, and it is more convenient for customers to test and maintain by themselves. Because the gas compression process is isothermal in the working process, it is not easy to explode when compressing and pumping flammable and explosive gas, so it is widely used in petroleum, chemical industry, pharmaceutical, food, sugar industry and other fields. Now let’s understand the correct operation process of the water ring pump, so that we can better use the water ring pump.

Water ring pump start

The water ring pump that has been stopped for a long time must rotate the coupling by hand for several revolutions before starting to verify that it is not stuck. The starting sequence is as follows.

1. Close the valve on the intake pipe.

2. Fill the stuffing box and gas water separator with water.

3. Start the motor when the air-water separator overflows.

4. Open the ball valve on the water supply pipeline.

5. Open the valve on the intake pipe.

6. Use the ball valve to adjust the water inflow to use the minimum water consumption to ensure the technical specifications required by the water ring pump.

Water ring pump stop (in the following order):

1. Close the valve on the intake pipe.

2. Turn off the motor.

3. Close the water valve.

4. When the water ring pump is stopped in winter, the pipe plug on the water ring pump shall be unscrewed to drain the water completely


Water ring pump maintenance:

1. The vacuum degree shall not be controlled by closing the valve.

2. Frequently check the fluctuation of vacuum degree and the vibration of water ring pump body.

3. Check whether the packing box is heated during operation and handle it in time.

4. Check whether there is noise in the operation of water ring pump, and handle in time in case of any abnormal condition.

5. Check whether the cooling water is blocked, and the water temperature shall not exceed 40 ℃.

6. Check whether all bolts and foundation anchor bolts are loose, and handle in time in case of looseness.

7. The installation position of water ring pump shall be clean, dry and well ventilated.

8. The packing shall be pressed regularly. If the packing fails to meet the sealing requirements, it shall be replaced in time.

9. The rolling bearing shall be well lubricated.

10. Check the rolling bearing temperature frequently during operation.

11. The bearings in normal operation shall be filled with oil 3-4 times a year, and the bearings shall be cleaned at least once a year and all lubricating oil shall be replaced.

12. Keep the pump body and accessories clean.

13. In winter, drain the water in the water ring pump and water tank after stopping.
