Leak Detection and Application of Vacuum Bellows

Helium Detection Equipment of Principle: Leak Detection and Application of Vacuum Bellows

Introduction

With the rapid development of modern industrial technology, the requirements for equipment sealing and reliability are also increasing. Especially in high-tech fields such as aerospace, aviation, ships, and nuclear power, any small leak can have a serious impact on the overall performance and safety of the equipment. In these fields, vacuum bellows, as an important elastic component, have particularly important sealing performance.

 

In order to meet the high requirements for sealing, helium detection equipment, as a high-precision and high-sensitivity leak detection device, is widely used in these fields. This article will provide a detailed introduction to the working principle of helium detection equipment and its application in vacuum bellows leak detection.

 

Leak detection of vacuum corrugated tube

As an elastic component widely used in high-tech fields, the sealing performance of vacuum bellows is crucial for the overall performance and safety of equipment. Traditional leak testing methods, such as dye penetration testing, refrigerant sniffing, or bubble testing, can no longer meet the demand for high-precision and high-sensitivity leak detection in these fields. Therefore, helium detection equipment has become a necessary means of vacuum bellows leakage detection.

In the leak detection process of vacuum bellows, negative pressure method (vacuum pumping method) is usually used to simulate the operating conditions. The specific steps are as follows:

Connect one end of the vacuum bellows to the leak detection port of the helium mass spectrometer leak detector, and seal the other end with a cover. Press the “Start” button on the leak detector, and the leak detector will start evacuating the bellows to a certain degree of vacuum. After reaching the testing conditions, use a spray gun to blow helium gas into the location that needs to be tested. If there is a leak in the product, helium gas will enter the interior of the product and be drawn into the leak detector. When the helium concentration exceeds the set alarm value, the leak detector will display the leakage rate and issue an audible and visual alarm, indicating that it is unqualified.

 

Helium detector for vacuum bellows of application and advantages

The application of helium detection equipment in vacuum bellows leak detection not only improves the accuracy and sensitivity of detection, but also has the following advantages:

1. Non destructive testing: Helium testing equipment will not cause any damage to the product during the testing process, ensuring the integrity and reliability of the product.

2. High precision detection: Helium detection equipment can detect extremely small leaks, meeting the demand for high-precision leak detection in high-tech fields.

3. Rapid detection: Helium detection equipment has a fast detection speed, which can greatly improve detection efficiency.

4. Wide applicability: Helium detection equipment is not only suitable for leak detection of vacuum corrugated tubes, but can also be applied to leak detection of various types of products and materials.

Conclusion

In summary, helium detection equipment, as a high-precision and high-sensitivity leak detection device, plays an important role in leak detection of vacuum corrugated tubes. The detection principle based on mass spectrometry technology ensures the accuracy and reliability of the detection. At the same time, helium detection equipment has the advantages of non destructiveness, high precision, speed, and wide applicability, making it widely used in leak detection in high-tech fields.
