The water ring vacuum pump is internally provided with an eccentric rotor with fixed blades, and is a rotary variable-volume vacuum pump with variable volume formed by the liquid ring and the rotor blades, wherein the liquid ring is concentric with the stator and is formed by throwing the liquid towards the wall of the stator.
When the water ring vacuum pump works, the water ring is formed by the water of the pump body, however, when the vacuum pump works for a long time, the temperature of the water rises due to friction, and when the pressure at the inlet of the impeller is low to a certain degree, the water in the pump body is vaporized and bubbles are generated; when the pressure at the inlet of the impeller continuously drops to the saturated vapor pressure of water, the water ring is in a boiling state, and the pumping quantity of the pump is reduced to zero; the pump can reach lower limit vacuum degree, and the required higher vacuum degree is difficult to reach. The higher the water temperature, the higher the saturated vapor pressure, and the higher the absolute pressure in the corresponding pump cavity, so that the lower the vacuum degree which can be pumped by the water ring pump. That is why a high water temperature reduces the vacuum. The ultimate vacuum of the water ring pump is basically equal to the saturated vapor pressure of the corresponding water temperature. Therefore, it is particularly important to cool the water ring vacuum pump when it is used.
