When employing a helium leak detector on a vacuum system equipped that consists of high quality vacuum equipment, it’s crucial to understand the distinct types of leaks: real leaks, virtual leaks, and permeation.
1. Real Leaks
These occur when a component being tested is compromised, resulting in a minuscule opening that permits gas infiltration. Detecting a real leak involves a multi-stage signal response. Initially, there is a sharp spike as helium is introduced, indicating the leak’s presence. This is followed by a sustained signal during the spraying process, affirming the leak’s persistence. Finally, as the spraying ceases, there is another sharp drop, signifying the end of the leak’s influence.
2. Virtual Leaks
The elusive nature of virtual leaks can present a significant challenge in the diagnostic process. When gas becomes entrapped within the vacuum chamber, it can give the impression of a genuine leak. This misdirection can lead to misidentification and, subsequently, delay in rectifying the actual issue. Understanding the nuances between virtual and real leaks is crucial for accurate diagnostics and effective troubleshooting.
3. Permeation
Permeation, though a gradual process, can have a cumulative impact on the performance of a vacuum system. Over time, helium diffusion through components like O-rings can alter pressure levels and potentially compromise the system’s effectiveness. Recognizing the subtle signs of permeation, including the delayed signal response and subsequent gradual decline, is vital for preemptive maintenance and ensuring the longevity of the system.
