Two Chamber Vacuum Helium Leak Detection Equipment
Product Introduction with Leak Testing Equipment:
According to the basic principle of helium leak detection, helium
is used as a tracer gas to fill the workpiece in a vacuum chamber.
Then, a helium leak detector is used to detect the helium signal in
the vacuum chamber, thereby quickly and accurately determining the
overall leakage situation of the workpiece with high precision.
The operator needs to push the workpiece into the vacuum chamber,
connect the quick-connect coupling inside the vacuum chamber to the
workpiece interface, press the close chamber button, and the system
can automatically complete the entire process of gross leak
detection, evacuation, micro-leak detection, helium recovery, and
so on.
Product Feature with Leak Testing Equipment:
1.Background Cleaning Technology
The system features a unique background cleaning technology. After
each inspection cycle, the vacuum chamber and associated piping
undergo thorough cleaning to ensure stability of the helium
background signal before commencing the next inspection.
2.Calibration Technology
Automatic calibration of the system: We have devised an automatic
calibration procedure that greatly facilitates regular and precise
calibration. This calibration system precisely determines the
overall leak rate of the workpiece.
Routine inspection of the system: A standard leak hole (designated
for daily inspections) simulates the workpiece being tested,
enabling online calibration of system accuracy, thus fully
guaranteeing the stability and reliability of the system's
precision.
3.User-Friendly Operation
This system integrates process automation technology with
electrical automatic control, enabling the entire workpiece
inspection process to be automatically controlled by PLC and a
touchscreen interface. Operators are only required to load and
unload workpieces, with no need for manual judgment. The PLC
program automatically evaluates the outcome of each step and
proceeds to the next based on preset conditions, thereby
eliminating the need for human intervention and freeing operators
from complex mental tasks.
4.Quality Assurance
As the entire inspection process is automated, eliminating the need
for human judgment and execution, it mitigates the influence of
human factors on inspection results, thus ensuring consistency,
objectivity, stability, and repeatability in operations.
The system is equipped with a 1.0×10^-6 mbar·l/s standard leak
hole. Relevant certificates are issued by the National Institute of
Metrology, China, making the accuracy and stability of the
equipment traceable to the national standard, thus ensuring
third-party recognition of the system's leak detection
capabilities.
