Helium Leak Detection Equipment: Technology, Application and Market Trends
 

I. Introduction
In modern industrial production, leak detection is a key link to ensure product quality, safety and operational efficiency. As an efficient and sensitive detection tool, helium leak detection equipment has been widely used in many fields due to its unique advantages. This article will introduce the technical principles, application scenarios and market trends of helium leak detection equipment in detail.

II. Technical Principles of Helium Leak Detection Equipment
(I) Characteristics of Helium Helium is an inert gas with the following unique characteristics:
• Stable chemical properties: Helium hardly reacts chemically with other substances and will not affect the detected object.
• Small molecular weight and strong permeability: Helium has a small molecular weight (4.0026) and can easily penetrate tiny pores to form a significant concentration gradient, which is easy to capture by the detection instrument.
• Easy to detect: The content of helium in the air is extremely low (the volume content in the atmosphere is about 1/52000). Once leaked, helium can be quickly detected by the helium mass spectrometer leak detector, and its mass spectrum peak is very sharp and easy to identify.
• Non-toxic and non-flammable: Helium is colorless, odorless, non-toxic, and non-flammable, making it safe to use in all kinds of environments.
(II) Working principle of helium mass spectrometer leak detector Helium mass spectrometer leak detector is the core equipment for helium leak detection. Its working principle is based on mass spectrometry technology and the characteristics of helium. The specific steps are as follows:
1. Gas sampling: The object to be detected is filled with helium, and the gas that may contain helium leakage is sucked into the instrument through a special sampling pipeline and pump system.
2. Ionization process: The gas entering the instrument is ionized in the ion source, usually by electron bombardment of the ion source, so that the gas molecules lose electrons and become positively charged ions.
3. Mass spectrometry analysis: The ionized ion beam enters the mass spectrometer, and the combined effect of the electric field and magnetic field is used to separate ions of different masses according to the mass-to-charge ratio of the ions.
4. Detection and signal processing: When helium ions reach the detector, they will generate a weak current signal, which is converted into data information related to the amount of helium leakage after amplification and processing.
(III) Detection methods There are mainly the following detection methods for helium mass spectrometer leak detectors:
1. Helium spray method: spray helium on the surface of the object to be detected, and determine whether there is a leak by detecting the helium signal outside the leak port.
2. Sniffer method: inject helium into the object to be detected, and detect the leaked helium on the surface of the object by using a sniffer.
3. Vacuum leak detection method: the sensitive components of the device to be detected and the leak detector are both in a vacuum, and the leak-indicating substance is applied to the outside of the device to be detected. The presence of a leak is determined by detecting the leak-indicating substance.
 

III. Application scenarios of helium leak detection equipment
(I) Aerospace field In aerospace equipment, helium leak detection equipment is used to detect leaks in rocket engines, satellite components, and aircraft sealing systems. Since these devices have extremely high requirements for sealing, helium leak detection equipment can quickly and accurately locate tiny leaks to ensure flight safety.
(II) Semiconductor manufacturing field In the semiconductor manufacturing process, the sealing of vacuum systems and clean rooms is crucial. Helium leak detection equipment can detect extremely small leaks, ensuring the stability of the production environment and product quality.
(III) Nuclear energy industry The sealing of nuclear energy equipment is directly related to nuclear safety. Helium leak detection equipment is widely used in leak detection of nuclear reactors, nuclear fuel assemblies, nuclear waste treatment facilities, etc., and can detect potential leakage risks in a timely manner.
(IV) Refrigeration equipment In refrigeration equipment, helium leak detection equipment is used to detect refrigerant leaks to ensure the efficient operation of the refrigeration system and avoid refrigerant pollution to the environment.
(V) Medical equipment Helium leak detection equipment is also widely used in the detection of medical equipment, such as medical gas pipelines, medical equipment sealing detection, etc., to ensure the safety and reliability of medical equipment.

Especially in high-tech fields such as aerospace, semiconductor manufacturing, and nuclear energy industry, the requirements for detection accuracy and efficiency are getting higher and higher, which has promoted the continuous growth of the helium leak detection equipment market. In addition, the strengthening of environmental protection policies and the acceleration of energy transformation have also provided a broad market space for the development of helium leak detection technology.
