Vacuum system negative pressure test
Thread Content
Is it necessary to fill the water seal tank during the negative pressure test of the vacuum system? What are the requirements for creating negative pressure?
When performing a negative pressure test on the vacuum system, a water seal tank is usually included in the test to ensure the sealing integrity and proper functioning of the entire system. The requirements for negative pressure testing include establishing a specific negative pressure value and maintaining that value for a certain period of time to check whether there are any leaks or a decline in performance in the system. The specific negative pressure value and testing time need to be determined based on the system design and usage requirements. .
Will the water in the water seal tank (room-temperature water) evaporate during the test and affect the vacuum level?
