Sealed Multistation Helium Mass Spectrometry Leak Detector
Product Introduction with Leak Testing Equipment:
The multi-station helium mass spectrometer leak detector is a
specialized instrument used to detect minute leaks in sealed
bodies. It utilizes helium as a tracer gas and employs mass
spectrometry analysis to achieve highly sensitive, rapid, and
accurate leak detection. This instrument supports simultaneous or
sequential operation of multiple stations, improving detection
efficiency and widely used in power electronics, automotive
manufacturing, air-conditioning and refrigeration industries, to
ensure product quality and safety.
Installation Requirements with Leak Testing Equipment:
(1) Main Power Supply
Electrical Parameters: Three-phase 5-wire 380VAC, power rating of
15KW.
Switch: One air switch, with a clearance height of ≥1.5M and a
distance to the equipment's mainframe placement location of ≤2M.
(2) Gas Source
① Helium: At least 1 bottle of bottled helium (40 liters, 12MPa)
with a 0.6MPa pressure reducing valve.
② High-purity Nitrogen: Bottled high-purity nitrogen (≥99.999%)
with a 0.2MPa pressure reducing valve.
③ Compressed Air: Clean compressed air with a pressure of ≥0.55MPa,
equipped with a 1/2″ ball valve.
The distance between the gas source interfaces and the equipment's
placement location should be ≤1M.
(3) Others
① Prepare an outdoor exhaust pipe with a diameter of ≥3/4″, and the
distance between the interface and the equipment's placement
location should be ≤1M.
Detection Process:
Installation of Workpiece: The operator inserts the workpiece into
the fixture hole, initiates the process, and the vacuum chamber
closes, commencing the inspection.
Macro Leak Detection: The vacuum pump evacuates the workpiece. If
the vacuum level reaches the standard, the process continues;
otherwise, a macro leak is indicated and the process ends.
Vacuum Chamber Evacuation: Initial and fine vacuum evacuation are
performed to ensure the vacuum level inside the chamber reaches the
set value.
Background Suppression: The leak detector measures the background
signal inside the chamber and performs suppression processing.
Helium Charging of Workpiece: Helium is charged into the workpiece
until the set pressure is reached.
Micro Leak Detection: During the leak detection period, if the leak
detector detects helium signals exceeding the standard, it
indicates a micro leak; otherwise, the workpiece is deemed
qualified.
Recovery and Refill: The workpiece is purged of helium, the vacuum
chamber is filled with nitrogen, and the helium in the fine
evacuation pipeline is purged.
Removal of Workpiece: The vacuum chamber opens, and the operator
removes the workpiece.
