Auto Vacuum Chamber Helium Leak Test System for Refrigeration Parts
For heat exchanger, valve, accumulator and refrigeration parts product requirements can not leak, usually adopts box type vacuum leak detection system can quickly determine the overall product has no leakage.
Vacuum chamber vacuum
The nitrogen in the setting pressure of the L workpiece is bigger and bigger, and the intensity is detected.
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
Production beat: 30 seconds / piece
Detection leakage rate: 1 x 10-5mbar.l/s (equivalent to 2 g / year R134a)
Detection pressure: 8 to 42bar
