Problems with vacuum pumps
Thread Content
The Nassim vacuum pump used for pressure reduction has had its blades fail several times; I’m not sure what the reason is
What material is it made of? Could you be more specific?
You must be using a water ring vacuum pump; there are many reasons for blade damage. First is the issue of product quality; however, since you’re using a joint-venture product, there should be no major problems. The second issue is related to usage – what is the temperature of the water used for cooling the pump? I hope you can provide this information. I suspect that poor cooling efficiency is causing cavitation inside the pump, which in turn leads to frequent damage of the impeller.
Is your gaseous medium corrosive when dissolved in water? What is the temperature of the water source for the water ring pump? If it is for reuse, is there a cooling device?
First is the issue of product quality; second is the problem with maintenance work; third is the incompatibility of the manufacturing process; fourth is improper operation and maintenance; fifth is simply bad luck: lol
