【 Professional Interpretation 】 Differences and Applications between Helium Leak Detection and Suction Gun Method and Helium Cover Method

The helium leak detection suction gun method and the helium hood method are two common helium leak detection methods, and there are some differences between them in terms of principle and application industries.

Helium Leak Detection Suction Gun Method: The helium leak detection suction gun method involves injecting helium into the object or system under test, and then using a suction gun to detect the leakage point. When helium escapes from the leakage point, the suction gun will absorb the surrounding helium, and analyze and locate the leakage point through a detector. This method is suitable for the detection of small or local leaks, such as those in pipelines, valves, joints, etc.

Typical Application Industries: Refrigeration and air conditioning, automotive manufacturing, aerospace, chemical engineering, etc.

Helium Hood Method: The helium hood method is to place the object or system under test in a sealed container, and then inject helium into the container. If there is a leak in the object or system under test, helium will enter the container from the leakage point, and then the leakage point will be analyzed and located through a detector. This method is suitable for the detection of large or overall leaks, such as vacuum equipment, sealing systems, etc.

Typical Application Industries: Semiconductor manufacturing, vacuum technology, aerospace, nuclear energy, etc.

In addition, there are common leak detection methods such as the back pressure method and the spray gun method for helium leak detection, and there are some differences between them in terms of principle and application scope. The helium mass spectrometer leak detectors produced by Anhui Nuoyi Technology have been widely used in many industries due to their excellent quality and stable performance. They can be used for single-machine leak detection, and can also be integrated into leak detection systems or PLCs.
