Vacuum Leak Test Systems

Leaks, even when they are small, can have a significant impact on the performance of a part or component or cause equipment to fail. Cracks and faulty seals are often the cause of these leaks, but they can often be detected by conducting vacuum testing on components prior to manufacturing.

真空泄漏测试的主要泄漏测试hod for testing sealed parts that could have leakage from an external source into their housings and casings. Prime candidates for vacuum leak test procedures include:

  • Underwater sensors or housings
  • Outdoor electrical housings
  • Sealed components
  • Components associated with vacuum sources

Is There A Difference Between Vacuum Leak Testing and Pressure Decay Testing?

During a vacuum leak test procedure, the part or vessel being tested (the test piece) is connected to a pressure/vacuum line and placed in the test chamber. The chamber is closed and sealed, all supply valves are closed, and the test piece and the chamber are simultaneously evacuated via vacuum to a preset pressure level. Once the pressure has stabilized, any pressure change in the test piece is compared to pressure changes in the chamber’s reference volume. If the test piece does, in fact, leak, the pressure difference between the two will increase. This data is measured and recorded.

Vacuum leak detection functions in a similar, but essentially opposite, manner aspressure decay testing. For instance, during pressure decay testing the test chamber is pressurized and the test chamber is monitored for a decrease in pressure indicating a leak from the chamber into the part. However, in vacuum decay the part being tested is pressurized and the test chamber is monitored for an increase in pressure indicating a leak from the part into the chamber.

Compared topressure decay testing, vacuum leak testing can provide better repeatability because it is less sensitive to environmental variables created by temperature changes. A vacuum leak detector often requires less time to reach a stable test pressure, is less susceptible to potential instability of tested parts, and offers shorter cycle times than tests in many pressure decay applications.
