Air tightness is one of the important technical indicators in modern industrial production. Whether it is automobiles, aircraft, medical equipment, or various containers and pipelines, they all need to maintain a certain level of air tightness and require a certain level of waterproof performance. Therefore, in various fields and industries, the use ofSealing Leak Detectorhas become an indispensable tool for quality control and monitoring.
1. Principles of air tightness testing technology.
The principle of air tightness testing technology is mainly based on the physical characteristics of gas flow and pressure changes. By applying a certain pressure to the product or system under test, and then observing the pressure changes or gas flow conditions, its air tightness performance can be determined. Commonly used methods arePressure decay method (pressure decay test)In the pressure decay method, a certain pressure is first applied to the product or system under test, and the initial pressure value is recorded. Then, the air or liquid supply source is shut off, and the pressure change over a period of time is observed. If the system pressure drops rapidly, there may be a leak or poor sealing performance. Conversely, if the system pressure changes very little, the product has good air tightness performance.
