Master these helium mass spectrometer leak detection techniques and easily detect leaks in vacuum coating equipment!

The correct use of a helium mass spectrometer leak detector is of great importance for detecting leaks in coating machine equipment and for daily maintenance. Vacuum coating equipment may have the problem of poor airtightness. If an airtightness test is carried out after maintenance, the production of many unqualified products can be avoided, thus saving costs.

Regarding the usage method of the helium mass spectrometer leak detector for vacuum coating machines, the following are some common questions and answers:

How does a helium mass spectrometer leak detector conduct an airtightness test for a vacuum coating machine?

The helium mass spectrometer leak detector uses the vacuum method for leak detection. Set the leak rate value in the vacuum mode, connect the helium mass spectrometer leak detector to the bypass of the coating machine through a bellows, and then spray helium at the places where leaks are suspected (such as pipelines, joints, etc.) to complete the leak detection.

What is the helium spraying method?

The helium spraying method is a commonly used helium mass spectrometry leak detection method in vacuum coating. It detects the presence of gas leaks by introducing helium into the component or system to be tested in the form of spraying, taking advantage of the high diffusivity and low solubility of helium.

What are the steps of using the helium spraying method for helium mass spectrometry leak detection?

Prepare a helium gas source and a helium spraying gun, set the detection parameters, spray helium, and analyze the detection results.

What are the applications of the helium spraying method in vacuum coating?

The helium spraying method can be used to detect leaks in the vacuum chamber and pipelines, detect leaks in coating components, as well as for quality control and quality assurance.

The helium mass spectrometer leak detectors produced by Anhui Nuoyi Technology have excellent quality and stable performance, and have been widely used in various industries. They can meet the needs of single-machine leak detection, and can also be integrated into leak detection systems or PLCs. The company has also established a complete after-sales service system, which provides a strong guarantee for the stable operation of the products.
