With the rapid development of urban planning and construction, water-ring vacuum pumps are now widely used in various projects, and their numerous advantages have been widely recognized. To ensure optimal performance and extend their service life, let’s take a look at how water temperature affects water-ring vacuum pumps.

Excessively high water temperature in a liquid-ring vacuum pump will inevitably cause the water to evaporate. Negative pressure conditions further accelerate this evaporation, resulting in an excessive amount of water vapor within the pump housing. Consequently, the liquid-ring vacuum pump draws in too much water vapor and very little external air, leading to a very low system vacuum level. There are two main factors contributing to excessively high water temperature: first, the supply water temperature is too high; second, the water temperature rises during operation.

Since water temperature is related to the intake volume, a higher working fluid temperature results in a decrease in air intake. As the temperature rises, the evaporation rate of the working fluid also increases, taking up the original discharge volume and reducing the intake volume, which in turn prolongs the vacuum pumping time. Furthermore, under vacuum conditions, the evaporation rate of the sealing fluid also increases. Combined with rising temperatures, the higher the percentage of displacement lost to evaporation, the more difficult it becomes to achieve a vacuum. As the data involved is extensive—the evaporation rate of the sealing fluid varies depending on both the specific vacuum level and temperature—specific figures cannot be provided. Only by observing changes in temperature at a given vacuum level can one understand how these changes affect evaporation rates. During operation, it is essential to consider temperature in conjunction with vacuum level to analyze the overlapping vacuum and pump performance curves.

Water temperature has a significant impact on water-ring vacuum pumps; temperatures that are too high or too low can cause adverse effects. Therefore, during operation, it is essential to strictly adhere to relevant standards and maintain the water temperature within a specified range. This places strict requirements on operators, who must be proficient in safe operating procedures to maximize the pump’s efficiency.

The above covers the impact of water temperature on water-ring vacuum pumps. Due to their various advantages, these pumps are widely used across many industries.
