liquid ring vacuum pumps material requirements

 liquid ring vacuum pump is a kind of equipment that puts the pump body into the water for pumping. Its use is very extensive in our life. However, due to the particularity of its working environment, there are certain requirements for its material. The following is a small series according to the relevant The information is summarized by everyone about the material requirements of the liquid ring vacuum pump:

1. Good chemical stability. The material of the water ring vacuum pump should have strong anti-oxidation and anti-corrosion ability, and does not react chemically with the working medium in the equipment and the gas discharge during the process.

2. The material of the other equipment must have good ductility, mechanical processing performance and welding performance, and it is easy to process into a complex shape shell.liquid-ring-vacuum-pump-in-petrochemical-industry

3. At the working temperature and baking temperature, the saturated vapor pressure should be low enough.

4, to have sufficient mechanical strength and rigidity, so as to ensure that the shell can withstand greater atmospheric pressure, can not be deformed during heating and baking.

5. Under the working vacuum and working temperature, the components inside the vacuum vessel should maintain good working performance.Roots_Vacuum_Pump


6, good thermal stability. Maintains good vacuum and mechanical properties throughout the system's operating temperature range.

7, good air tightness. In operation, it should be kept under a high vacuum environment, so the material of the wall should not have porous structure, cracks or other defects forming leakage, and the permeation rate and outgassing rate should be low.

The material requirements for the liquid ring vacuum pump are the above points, that is to say, the material has a certain strength and stability, and since it is a vacuum device, it requires a good air tightness, so that the device can be further protected.
