    Tips: How Does Water Ring Vacuum Pump Work?

    A water ring vacuum pump is a type of positive displacement pump that is used to create a vacuum in various industrial applications. It operates based on the principle of creating a rotating liquid ring to compress and evacuate gases from a closed system. This cyclic process of creating a rotating liquid ring, trapping and compressing gases, and discharging them is repeated continuously to maintain the desired level of vacuum in the system.
