Application
Helium leak detection equipment for the automotive industry, mainly used in air conditioning systems, including condensers, evaporators, compressors, expansion valves and lines;
Fuel systems, including fuel tanks, fuel distributors, regulators and lines, etc;
Others, including oil cooler, water tank and aluminum wheel hub, etc.
Technical characteristics
- Mostly helium-filled boxes with in-box detection.
- High degree of automation, fast beat, can be configured with in-box rollers to realize 24-hour fully automatic unmanned production.
- With helium recovery system to realize helium recycling, which can greatly reduce the cost of use, optional remote monitoring function.
Main technical parameters
- Detection accuracy: refrigerant 1g/year～14g/year;
- Detection beat: two boxes linkage 30S ~ 60S / box, 1 box can put 2 pieces;
- Vacuum chamber size: customized according to the shape and size of the inspected workpiece;
- Evacuation and helium filling mode: evacuation and helium filling inside the vacuum box;
- Door opening method: slant lift type/duckbill type/flap type/bell type etc;
- Leakage detection features: large leakage detection, medium leakage detection, micro leakage detection three-level leakage detection technology, can check the overall leakage rate can also find the leakage point;
- Helium recovery rate: greater than 98%, using low-pressure helium filling and sealing upgrade, which greatly improves the helium recovery rate;
- Control mode: PLC control, touch screen operation;
- Degree of automation: after connecting the workpiece manually, start the equipment: opening and closing the door, inflating and checking the big leakage, evacuating, filling helium, detecting and recovering are fully automated;
- Safety protection: grating protection, electrical interlock protection, hierarchical password control, sound and light alarm;
- Main configuration: all key components are imported brands.
