Vacuümdalingstesten

Vacuümdalingstesten, often translated as vacuum decay testing, is a diagnostic procedure used to assess the integrity of a vacuum system. This type of testing is crucial in various industries, including manufacturing, research and development, and aerospace, where maintaining a specific pressure level is critical for proper operation or experimental accuracy. The fundamental principle involves monitoring the rate at which a vacuum system loses its vacuum over a set period.

The process typically begins by evacuating the system to the desired low-pressure state. Once the target vacuum is achieved, the system is isolated from the vacuum pump, and a pressure gauge is used to continuously measure the internal pressure. If the vacuum is stable, the pressure reading should remain constant or change very minimally. However, if there are leaks within the system, such as faulty seals, cracked components, or permeable materials, the internal pressure will gradually increase as air or other gases from the surrounding environment enter the system.

The rate of pressure increase, or "leak rate," is then calculated. This rate provides an indication of the severity and location of any potential leaks. A higher leak rate suggests a more significant breach in the vacuum integrity. By comparing the measured leak rate against predefined acceptable limits, engineers and technicians can determine if the vacuum system is functioning as intended or if repairs are necessary. Vacuümdalingstesten is a non-destructive method that helps ensure the reliability and performance of sensitive vacuum-dependent equipment and processes.
