Detection Precision

The minimum detectable leak rate is 2 grams/year, equivalent to  (a very low leak rate that can effectively detect even the slightest leaks in automotive air - conditioning pipes, ensuring product quality and system performance).

Vacuum Chamber

There are 2 vacuum chambers with dimensions of 1200mm (length) × 600mm (width) × 400mm (height). The inner surface of the vacuum chamber is made of stainless steel and is specially treated to reduce outgassing and helium adsorption. The duck - bill - type door opening and closing mechanism, along with safety devices like light - curtain protectors and mechanical protection devices, ensures operator safety during the detection process.

Detection Process

For large - leak detection, it uses positive pressure with nitrogen or high - pressure air at 45 bar. For micro - leak detection, 100% helium gas at 30 bar (within the range of 15 - 40 bar) is used. Each process is strictly time - controlled. For example, if the vacuum degree of the vacuum chamber cannot reach the set value within 30 seconds during evacuation, the system will stop the detection program and issue an alarm, ensuring the reliability of the detection results.

Production Efficiency

The production cycle is 10 seconds per piece when two chambers operate in tandem (each chamber can hold 4 pieces), excluding loading and unloading time. The single - chamber mechanical cycle is 80 seconds, which can meet the high - volume production needs of automotive air - conditioning pipe manufacturers, improving production efficiency and reducing costs.

Helium Recovery

The helium recovery rate is as high as 95%, which not only saves costs associated with helium consumption but also reduces environmental impact, making it an environmentally friendly and cost - effective choice.

Key Components

The system is equipped with top - brand components. The leak detector is from German INFICON, with a maximum detection accuracy of . The vacuum pumps are from LEYBOLD, ensuring stable and reliable operation. Other components such as vacuum valves, vacuum gauges, pressure sensors, etc., are sourced from well - known brands like SEIT, GE, BURKERT, and OMRON, guaranteeing the overall performance and durability of the system.

Safety and Convenience

The system has multiple safety protection measures. High - pressure containers have pressure vessel certificates, over - pressure safety valves, and sensor over - pressure alarms. Electrical components meet safety standards, with proper grounding and leakage protection, and motors are protected against short - circuit and overload. It also features a user - friendly PLC and touch - screen control system. Operators can easily adjust device settings, monitor the operation status of each part of the device in real - time, and choose between automatic and manual operation modes according to different scenarios, such as device testing, maintenance, and normal production.

After - sales Service

The supplier provides comprehensive after - sales support. It offers free training for operators, maintenance, and repair personnel for at least 24 hours, enabling users to quickly master the operation and maintenance skills of the equipment. The equipment comes with a 12 - month free warranty period starting 30 days after it reaches the user's factory (excluding consumable parts like seals, gaskets, vacuum pump oil, and filter cartridges). Additionally, the supplier provides at least one free maintenance visit per year after the warranty period and continues to supply spare parts, ensuring the long - term stable operation of the equipment.
