High Precision Direct-Cooling Plate Helium Leak Testing Machine
For Leak Testing Equipment
Product Introduction: It's a direct-cooled plate airtight helium leak detector with
processes like loading, scanning, evacuation, leak detection,
helium filling, and unloading. It detects helium signals to
determine workpiece leakage and can switch to suction gun mode for
leak point location.
Product Features:
Frame and Cover Plate Unit: Main frame is iron/aluminum profiles, cover plates are painted
iron in national standard light gray (RAL 7035).
Vacuum Pumping Unit: Comprises vacuum pumps, measurement systems, valves, and piping.
Helium Recovery Unit: Made of buffer tank, compressor, low-pressure vessel, valves, and
piping to recover helium.
Helium Filling Unit: Has high-pressure helium tank, valves, and piping. Filling
pressure adjustable from 0 to 4 MPa with auto shutdown.
Automatic Helium Replenishment Function Module: Adds fresh helium when system level is low.
Helium Concentration Monitoring Unit: Monitors and controls helium filling with online real-time
monitor.
Leak Detection Unit: Has vacuum chamber detection and suction gun location modes.
