nowAir tightness testing equipmentThere are various methods and methods, and everyone is interested inAir tightness testing methodThe choice was also at a loss. Hai Ruisi acted asAir tightness testingThe industry leader tells everyone: ChooseAir tightness testing equipmentThe following factors should be considered when choosing methods:

1. Consistency

For some leak detection methods, the test results obtained are basically the same regardless of whether the inspector is skilled or not; some methods are used by experts and laymen, and the results are completely different.Where possible, methods should be used that do not require skilled expertise for correct detection.Each method has different technical keys, and different leak detection personnel may not be able to obtain consistent leak detection results.

2. Stability

Air tightness testingIt is a comprehensive technology of measurement and testing.If the data obtained by the test is unstable, it is meaningless.correctAir tightness testingNot only does the detection instrument need to be stable, but the detection method itself also needs to have good stability.

3. Reliability

No leakage detected does not mean there is no leakage, and this should be judged.When using a certain method to detect leaks, you should know whether the method is reliable.The reliability of leak detection results is related to the consistency, stability and other factors of the method introduced above.

4. Leak detection principle

No matter whichAir tightness testing method, its basic principles must be understood.Air tightness testing methodThe content involved is wide and reflects various measurement and testing technologies.It is not easy to understand the principles of many detection methods in detail.This book will briefly introduce the basic principles of commonly used leak detection methods.

5. Response time

No matter what method is used, it will always take a certain amount of time to detect the leakage rate.The length of the response time may affect the accuracy and sensitivity of leak detection.Generally, extending the detection time will improve the sensitivity. However, if the detection time is too long, the detection accuracy may be reduced due to changes in environmental conditions.Response time includesAir tightness testingThe response time of the instrument itself, the lag time of gas flow and the time required for various preparations.This must be taken into consideration when choosing a leak detection method.

6. Judgment of leakage point

someAir tightness testing methodIt can only determine whether there is a leak in the system, but cannot determine where the leak point is. Some leak detection methods can not only determine the leak point, but also determine the size of the leak rate.If it is just to find out whether the device is qualified, the former method can be used.When performing maintenance or finding out the cause of leakage, the latter method must be used, and sometimes missed detection may occur when using the latter method.
