Auto Vacuum Chamber Helium Leak Test System for Cast-aluminum Shell of Switch Gears

Equipment Overview
Casting aluminum shell to be filled with SF6 gas, can not leak, but there may be casting defects, filling gas before the gas tightness test. Aluminum switch leak detection usually adopts helium leak detection system of automatic vacuum box.
Detection principle
Vacuum chamber vacuum
The nitrogen in the setting pressure of the L workpiece is bigger and bigger, and the intensity is detected.
Workpiece nitrogen
Workpiece vacuum
Workpiece filled with helium;
Detector from the vacuum box detection signal to determine a small leak of helium
Recovery of helium
Vacuum tank filling atmosphere
