Automatically Vacuum Chamber Helium Leak Test System for Automobile Parts
It is requred to be leak free for the radiators, heat-exchangers, oil-exchangers, fuel tanks and others else automobile parts. As there might have welding defects, it is necessary to do leak test before vehicle assembly. The normal solution is auto vacuum chamber helium leak test system, the integral leak would be tested quickly and precisely.
Test Concept
Charge high pressure gas into the product for gross leak test and proof test；
Evacute the vacuum chamber.
Vent gas from the product.
Evacuate the product and charge helium into the product.
Test the helium signal from the vacuum chamber by the leak detector for fine leak judge.
Recover helium from the product.
Vent vacuum chamber.
