Help: Regarding jet vacuum pumps
Thread Content
This post was last edited by Zou Yang on 2010-9-26 at 14:06. The vacuum level of the jet vacuum pump in our factory is always not high enough. During the production process, it was found that the temperature of the circulating water kept rising. Will this affect the vacuum effect? What aspects should be considered when checking a jet vacuum pump? Since the employees in our factory are all newcomers, they don’t know much about this equipment. I would appreciate it if experts could offer their guidance. Medium: water. Temperature: it hasn’t been measured; everyone tested the water temperature with their hands and found it to be hot. The working environment is in the replacement workshop, serving the deoxidation tower. The water tank is outside. Now that circulating water is connected, it seems to work fine. The original water
High water temperature can affect the vacuum level. Please, the original poster, provide details such as the jet medium, pressure, temperature, and operating environment, so that everyone can analyze the situation.

Pumping air with water? Temperature has a significant impact.
Reply to 4# steincat: Could you explain in detail why it has an impact? I don’t quite understand
For example, the saturated vapor pressure of water at 30°C is approximately 4.25 kPa(A); therefore, a jet vacuum pump that uses water at 30°C as its working fluid cannot achieve a pressure lower than 4.25 kPa(A), since the water will vaporize at that pressure.
I’ve learned it.* . . . . . , can gasoline or diesel be used as the power medium? The media I need to extract are also gasoline+air, diesel+air.
