Background
In the use process of the water ring type vacuum pump, the water temperature is too high or too low to adversely affect the efficiency of the pump, and the service life of the pump is even shortened. The water can be evaporated due to the fact that the water temperature is too high, and the water evaporation and evaporation are further aggravated under the negative pressure working condition, so that the water vapor in the pump body is too much. When the water ring vacuum pump pumps too much water vapor, it is rarely inhaled from the outside, resulting in a very low vacuum system. Since the water temperature is related to the intake amount, the air amount decreases when the working fluid temperature is high. As the temperature increases, the amount of evaporation increases, taking up the original space, and the decrease in suction will extend the vacuum time.

As the temperature increases, the greater the percentage of exhaust gas volume, the air cannot be extracted properly. In the prior art, the water ring vacuum pump has the defects of low efficiency, short service life and high electric energy consumption caused by overhigh inlet water temperature, high working temperature and large load. Accordingly, the prior art is subject to further development.
