High Efficiency 3 Stations Relay Automatic Helium Leak Detection
Equipment: Advanced and Precise Solution for Leak Testing with
Enhanced Productivity and Reliability
Operation Process
Testing Sequence: The equipment's operation starts with the vacuum chamber closing.
A major leak test is conducted first. If the vacuum level meets the
set standard, the process proceeds; otherwise, it stops with a
major leak indication. Then, the vacuum chamber is evacuated in
stages to the set vacuum level. After suppressing the background
signal, helium is filled into the workpiece. During the micro-leak
test, if the detected helium signal exceeds the limit, the
micro-leak indicator light turns on; otherwise, the pass indicator
light is on. After testing, helium is purged, the chamber is filled
with air, and the piping is purged. Finally, the chamber opens, and
the workpiece is removed.
Chamber Operation Modes: The system supports simultaneous or sequential testing of three
chambers (A, B, C), allowing for independent or synchronized
operation to boost efficiency.
Installation Requirements
Professional Installation: Must be installed by trained professionals only.
Power Supply: Requires a three-phase 5-wire 380VAC power supply with 5KW power.
The air switch should be at a height ≥1.5M from the ground and ≤2M
from the main unit, with electrical parameters specified.
Gas Sources: Needs bottled helium (40 liters 12MPa) ≥1 bottle with a 0.6MPa
pressure reducing valve, bottled high-purity nitrogen (≥99.999%)
with a 0.2MPa pressure reducing valve, and clean compressed air
≥0.55MPa with a 1/2″ ball valve. The distance between gas source
interfaces and the machine should be ≤1M.
Exhaust Pipe: An outdoor exhaust pipe with a diameter ≥3/4″ is required, and
its interface should be ≤1M from the machine.
