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.
真空泄漏测试是用于测试密封零件的主要泄漏测试方法，这些零件可能会从外部来源泄漏到其外壳和壳体中。真空泄漏测试程序的主要候选人包括：
- 水下传感器或房屋
- 户外电气外壳
- Sealed components
- 与真空源相关的组件
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.真空泄漏检测功能以类似但基本相反的方式，例如压力衰减测试。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.
相比压力衰减测试, 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.
