Automatically Vacuum Chamber Helium Leak Test System for Refrigeration Parts
It is required to be leak free for the heat-exchangers, valves, reservoirs and others else refrigeration parts. As there might have welding defects, it is necessary to do leak test before product 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.
