In the high-end manufacturing fields such as semiconductor chip packaging, aerospace sealing components, and new energy batteries, airtightness detection has become a crucial link in ensuring product reliability and safety. As an important branch of helium mass spectrometry leak detection technology, the suction gun type helium leak detector, with its flexible and efficient detection method, holds a pivotal position in the market of leak detection equipment. With the global manufacturing industry's increasing demand for the detection accuracy of micro-leaks, which has been raised to the level of 10⁻⁹ Pa·m³/s, the helium leak detection technology is evolving towards higher sensitivity, intelligence, and portability.·
As a source manufacturer deeply engaged in the research and development of leak detection equipment, the HJ141 suction gun type helium leak detector we have launched is a profound response to the needs of the evolution of industry technology. The HJ141 is based on the principle of magnetic deflection mass spectrometry analysis. It innovatively combines a two-stage vacuum pumping system with a highly sensitive helium ion capture device, achieving a minimum detectable leak rate of 1×10⁻⁸ Pa·m³/s, which is 30% more sensitive than the previous generation products. In the mass spectrometry analysis module, the core of the technology, a miniaturized quadrupole mass analyzer developed independently is adopted. By optimizing the parameters of the electromagnetic field and the design of ion optics, the interference of background noise is effectively reduced, ensuring the accuracy of detection data in complex industrial environments.
The practicality of this device is also remarkable. The suction gun designed according to ergonomics is equipped with an intelligent flow regulating valve, which can flexibly control the intake of helium according to the detection scenarios. With a detachable probe nozzle, it can meet the detection requirements of narrow spaces and complex structural parts. The built-in intelligent algorithm supports functions such as automatic calibration, background compensation, and leakage source location, and the detection efficiency is 40% higher than that of traditional equipment. In the detection of new energy vehicle battery packs, the HJ141 can complete the scanning of the sealing surface within 30 seconds and accurately locate micron-level leakage points, providing a reliable guarantee for the safety of the batteries.
From the perspective of the development trend of the industry, the helium leak detection technology is accelerating its integration with the Internet of Things (IoT) and artificial intelligence (AI). Our R&D team has already started to connect the HJ141 to the industrial Internet platform, and realize the health management and predictive maintenance of the equipment through cloud data analysis. In the future, this product will further integrate AI image recognition technology, automatically generate leakage reports by scanning the detected parts, and promote the helium leak detection equipment towards the direction of intelligence and unmanned operation.
As a source manufacturer, we not only provide detection equipment with excellent performance but also, relying on a complete R&D and production system, offer customized detection solutions for customers. Whether it is the ultra-high vacuum leak detection in the aerospace field or the aseptic sealing detection of medical devices, the HJ141 suction gun type helium leak detector safeguards the quality of precision manufacturing with its reliable technical performance.
