Application:
The hose helium leak detector is quite suitable for air tightness test for automotive air conditioning hose, fuel oil hose, brake hose, engine hose and etc.
Working principle and structure:
In accordance to the basic principle of helium leak detection, we adopt helium, rather than Freon, as the tracer gas. After charging helium into the testing object within vacuum pump, the helium leak detector will be adopted for leak testing. The testing method features high precision and fast detection.
The hose helium leak detector is equipped with two vacuum pumps. After placing the testing objects within vacuum pump, and sealing it with coupling, the door will be closed. After that, a comprehensive array of processes will be automatically delivered, including gross leak test, strength test, evacuating, helium charging, micro-leakage test, helium recovery and etc. The system features fast cycle and high testing precision.
