Water-ring vacuum pumps are now widely used, and their characteristics are widely recognised. To ensure optimal performance and extend their service life, let us now examine the material requirements for water-ring vacuum pumps.

Water-ring vacuum pumps are extensively used due to their compact size, high efficiency and ease of use. Firstly, the materials must possess sufficient mechanical strength and rigidity to ensure that the casing can withstand atmospheric pressure and does not deform during heating and curing. Good chemical stability. The materials used in the vacuum pump must possess strong resistance to oxidation and corrosion, and must not react chemically with the working medium inside the pump or the exhaust gases generated during the process. The saturated vapour pressure of the water-ring vacuum pump must be sufficiently low at both operating and baking temperatures.

Water-ring vacuum pumps must exhibit good thermal stability. Within the system’s operating temperature range, they must consistently maintain good vacuum performance and mechanical properties. At the operating vacuum level and temperature, the equipment inside the vacuum chamber must maintain good operational performance. The materials used for the vacuum pump should possess good ductility, machinability and weldability, and be easy to process into complex-shaped casings. Good airtightness is essential. As the pump must operate in a high-vacuum environment, the materials used for the vessel walls must be free from porous structures, cracks or other defects that could cause leakage, and must exhibit low permeation and outgassing rates.

The above outlines the material requirements for water-ring vacuum pumps. Given their characteristics and increasingly widespread application, we would like to remind readers once again to select the appropriate model based on actual conditions and to combine this with correct operating procedures to achieve optimal results. We hope the information provided here proves helpful.
