As water-ring vacuum pumps have come to be widely used in various large-scale engineering projects, their operational advantages have been widely recognised. To ensure their optimal use, let us take a look at the operational requirements for running a water-ring vacuum pump.

When operating a water-ring vacuum pump, the power supply cables and other electrical equipment must be connected in accordance with the motor’s specifications, and the motor must be reliably earthed. Preparatory work before starting the water-ring vacuum pump includes filling the pump with water, briefly energising the motor, and stopping the motor once the rotation direction has been correctly adjusted. When starting the water-ring vacuum pump, close the inlet valve and open the bypass valve. Supply water to the pump and start the motor. Slowly close the bypass valve whilst simultaneously opening the inlet valve. Adjust the water supply valve to ensure the vacuum pump operates at the appropriate water flow rate.

To shut down the liquid ring vacuum pump, close the water supply valve to stop the water flow. Close the inlet valve, open the bypass valve, and then switch off the power to stop the pump.

The above outlines the operational requirements for liquid ring vacuum pumps. As these pumps are characterised by stable and reliable performance and a long service life when used over extended periods, it is essential to follow the correct procedures during operation to avoid unnecessary complications.
