Vacuum Helium Leak Test System for Power Relays With 3 Vacuum Chambers
Basic Functions:
Operator inserts copper tube of the product into the fixture hole and presses the start button, the functions of closing the chamber, vacuuming the chamber, vacuuming the product, filling the product, vacuum leak detection, and venting the chamber can be automatically finished.
Special Sealing Fixture:
Adopts a special sealing structure design, which can solve the connection and sealing problem between the workpiece and the system. The sealing performance can reach leakage ≤1×10-9Pa.M3/s, which ensures that the helium gas detected during the leak detection process is possible from the workpiece. Leak Testing Equipment
Background Cleaning Technology:
HJ AUTO's patented helium background noise cleaning technology can effectively remove the helium background noise of the vacuum chamber system, provide a clean and stable reference background environment for the system, and avoid the system's radon background noise level to excessively affect the stability of the system operation, and improve the operating efficiency of the system.
