Mine safety is always the top priority. As the essential life-saving equipment for underground workers, self-rescuers rely entirely on sound air tightness to deliver reliable protection in emergencies, serving as a critical line of defense for mine safety.
Traditional air tightness testing equipment for self-rescuers suffers from prominent drawbacks: heavy manual operation, low testing efficiency, poor pressure control accuracy and test results easily affected by human factors. Most conventional units are bulky and heavy, making transportation and on-site deployment difficult, which can no longer meet the demands of modern mines for high-frequency, high-precision and standard-compliant detection.
With years of expertise and profound technical accumulation in mine safety equipment, Henan Huining Electronic Technology is proud to launch its new intelligent self-rescuer air tightness tester. Featuring intelligent control, superior precision and lightweight structure, this new product sets a new benchmark for self-rescuer air tightness testing and reinforces safety protection for mining operations.
Intelligent Upgrade: Eliminate Human Errors for Accurate & Efficient Testing
This new tester abandons the traditional manual testing mode, equipped with high-precision pressure sensors and a PLC intelligent control system to realize fully automatic operation. The pressure can be digitally adjusted within the range of 0-20 kPa. The device automatically stops pressurization and starts timing once the preset pressure is reached, requiring no manual intervention throughout the process. It effectively avoids pressure deviation and timing errors caused by manual operation.
The pressure detection accuracy reaches ±1 Pa, and the time accuracy is up to 0.01 seconds, enabling it to accurately detect tiny air leakage and fully comply with industry standards. A 7-inch high-definition touch screen delivers a user-friendly interface, displaying real-time pressure, time and other core data clearly.
Dual reminder functions including voice broadcast and buzzer alarm will notify operators of pass/fail results upon test completion, so even novice users can operate it effortlessly. Built-in data storage module automatically records test time, pressure data and inspection results. Supported data export and report printing help enterprises establish complete inspection archives and satisfy regulatory requirements.
Lightweight & Durable Design for Versatile Application
To solve the problem of poor portability of old models, this tester adopts high-strength lightweight materials and a compact structure. The total weight is only 16 kg with dimensions of 450×400×200mm, which is easy to carry and quick to set up. It is well suited for underground routine inspection, batch testing in warehouses and factory quality inspection for self-rescuer manufacturers, greatly reducing labor intensity.
The whole machine adopts anti-corrosion and anti-aging craftsmanship. Pipes and sealing components are made of wear-resistant materials, adapting to the harsh working environment with high humidity and dense dust in mines. The equipment runs stably with long service life and low maintenance frequency, cutting down long-term operating costs. It is compatible with filter-type, chemical oxygen and compressed oxygen self-rescuers. One unit fits multiple models, widely applicable to mines, chemical plants, fire departments and self-rescuer manufacturers.
Exquisite Quality Guards Safety & Boosts Industrial Development
As a leading supplier in the mine safety equipment industry, Henan Huining adheres to the philosophy of Empowering Safety with Technology, Forging Excellence with Quality. The launch of the new intelligent tester demonstrates our strong R&D capability and sense of responsibility for mine safety.
Combining automatic operation, high precision, easy operation and wide adaptability, this product solves the pain points of traditional testing equipment. It prevents unqualified self-rescuers from being put into service from the source and fully safeguards the personal safety of frontline workers.
