Pressure requirements for airtightness testing of self-cleaning seal type water ring vacuum pumps
Thread Content
Hello everyone. Before the New Year, our factory carried out maintenance on two self-cleaning sealed water ring vacuum pumps. During the airtightness testing after the equipment was installed, the maintenance staff said that the airtightness pressure should not exceed 1.5 kilograms. Depending on the operating conditions of the pump. I couldn’t find any information on this topic online, so I would like to ask everyone for help.
The airtightness test is conducted at 25 psi, which is equivalent to 1.7 bar; the pressure is held for 5 minutes, with a pressure drop of less than 2 psi, or 0.14 bar
Thank you very much. Is the airtight pressure for all self-sealing vacuum vane pumps 1.7 Bbar? If the pressure drop remains below 0.14 Bar after 5 minutes, is that considered acceptable?
The answer above is correct; one can refer to the test procedure specifications in 10.3.4.2 of API682
The reply is given below; take a look at API682
Do you have this information on API682?
