Water-ring vacuum pumps are now widely used, and their operational characteristics and advantages are widely recognised. To ensure their effective use in the future, let us now take a look at the operational requirements for water-ring vacuum pumps.

During the operation of a water-ring vacuum pump, when starting the pump, the power cable and other electrical equipment must be connected in accordance with the motor’s specifications, and the motor must be reliably earthed. Pre-startup preparations for a liquid-ring vacuum pump involve filling the pump with water, starting the motor, adjusting the motor’s rotation direction, and then shutting down the pump.

When starting a liquid-ring vacuum pump, close the inlet valve, open the bypass valve, and introduce water into the pump to start the motor. Gradually close the bypass valve whilst simultaneously opening the inlet valve; adjust the water supply valve to ensure the vacuum pump operates with an appropriate water flow rate.

When stopping the water-ring vacuum pump, close the water supply valve to stop the water supply, close the inlet valve, open the bypass valve, switch off the power supply, and carry out the necessary checks before proceeding.

The above outlines the operational requirements for water-ring vacuum pumps. Given their distinctive features and advantages, their use is becoming increasingly widespread. We would like to remind you once again that, during operation, you must select the correct method based on the actual circumstances in order to achieve the best results. We hope the information provided here proves helpful.
