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 recognised. To ensure optimal performance, let us take a look at the water temperature requirements for water ring vacuum pumps.

When using water-ring vacuum pumps, we often find that the longer they are in operation, the more issues or faults arise, and the greater the number of factors affecting their performance. Water temperature is one such factor. If the water temperature is too high or too low, it will adversely affect the pump’s efficiency and may even shorten its service life. Excessively high water temperatures inevitably cause the water to vaporise, and the negative pressure operating conditions further exacerbate this process, resulting in an excessive build-up of water vapour within the pump housing. As the water ring vacuum pump draws in an excessive amount of water vapour during the intake phase whilst drawing in very little external gas, this leads to a very low system vacuum level. There are two primary factors contributing to excessively high water temperatures: firstly, the supply water temperature is too high; and secondly, the water heats up during operation.

As water temperature is related to the intake volume, a higher working fluid temperature results in a gradual decrease in gas volume. As the temperature rises, the evaporation rate of the working fluid increases, occupying the original discharge volume and reducing the intake volume, which prolongs the vacuum pumping time. Furthermore, under vacuum conditions, the evaporation rate of the sealing fluid also increases; combined with the rise in temperature, the percentage of discharge volume occupied by the sealant grows, potentially leading to an inability to achieve a vacuum. As the data involved is too complex—with the evaporation rates of the sealing fluid varying significantly across different vacuum levels and temperatures—it is impossible to provide specific figures. Only by considering a specific vacuum level can one observe how temperature changes affect evaporation rates. During operation, it is essential to overlay the performance curves for temperature and vacuum against the pump’s performance curve to identify these relationships. Water temperature has a significant impact on water-ring vacuum pumps; temperatures that are either too high or too low will result in adverse effects.

The above outlines the water temperature requirements for water ring vacuum pumps. Only through high-quality products and correct operating procedures can optimal performance be achieved.
