Basic Leak Detection Principle:

According to the basic leak detection principle of helium leak detection, helium gas is used as the tracer gas, and helium gas is filled into the test piece in the vacuum chamber. Then, the helium signal in the vacuum chamber is detected by the helium leak detector, so that the overall leakage of the test piece can be judged quickly and accurately with high precision.

 

Basic Function:

The operator pushes the test piece into the vacuum chamber, connects the quick-connect joint in the vacuum chamber with the test piece interface, and presses the chamber closing button to automatically close the vacuum chamber door. The system can automatically realize the whole procedure of evacuation, large leak detection, helium filling, micro leak detection, helium recovery and SF6 filling.

 

Work Process Description

Test piece installation

The operator pushes the test piece into the vacuum chamber, and connects the quick-connect joint in the vacuum chamber with the test piece interface

Manually press the chamber close button, the vacuum chamber door automatically closes, and the detection cycle starts immediately

Vacuum chamber and Test piece vacuuming

Automatically vacuum the vacuum chamber and test piece at the same time

When the vacuum degree reaches the set value, the evacuation process of the test piece stops, and the vacuum chamber continues to be pumped to the set pressure for leak detection.

During the evacuation of the vacuum chamber, the test piece is checked for large leaks

Ø  If the test piece has a large leak, the system will stop the inspection programLarge leakage indication signal is given on the operation interface

Ø  If the test piece has no major leakage, the system continues to perform the following inspection procedures

During the above detection process, if

·        The vacuum degree in the vacuum chamber cannot reach the set vacuum value within the set evacuation time

·        The vacuum degree in the test piece cannot reach the set vacuum value within the set evacuation time

The system will abort the leak detection procedure and issue an alarm signal

Background zero suppression,

Fill helium into test piece

and Vacuum helium detection

Automatically detect the background signal of helium in the vacuum box and suppress the background signal to zero

Automatic filling of the test piece with helium

Automatically judge the micro-leakage of the test piece

Ø  If the leak detector finds that there is a helium signal exceeding the set value in the vacuum chamber, it indicates that the test piece has a micro-leakage, and a micro-leakage indication signal is given on the operation interface.

Ø  If the leak detector does not find that there is a helium signal exceeding the set value in the vacuum chamber, it indicates that the micro-leak detection of the test piece is qualified, and a qualified signal is given on the operation interface.

Helium Recovery

Ø  Automatic recovery of helium in the test piece until it reach the set recovery vacuum degree

Vacuum chamber filled with air and Test piece SF6 filling

The vacuum chamber is filled with air

During the inflation of the vacuum chamber, the test piece is automatically filled with SF6 of the set pressure

When the SF6 filling procedure is completed and the vacuum chamber is filled with air, the system will give a completion signal

Test piece unloading

If the test is passes

Vacuum chamber door opens automatically

The operator disengages the in-box joint from the test piece interface

If the test fails

Manually press the confirmation button, the vacuum chamber door opens automatically

The operator disengages the in-box joint from the test piece interface

If the device alarms during the detection process

Press the confirm button manually

Vacuum chamber door opens automaticallyPress the touch screen fault information prompt, cancel the alarm state, and then re-detect the test piece.
