It is suitable for leakage detection of devices, compressors, fuel tanks and other products in the automotive industry. It adopts the method of internal inspection in a helium-filled tank, which has a reliable safety factor. The equipment uses a helium mass spectrometer leak detector, which has high leak detection accuracy and low false detection rate, meeting the customer's high-precision detection requirements for annual leakage of 1g/year.
Helium leak detection system for vacuum boxes in the automotive industry
Vacuum box leak detection system
- Fill the inspected workpiece with high-pressure nitrogen to determine its pressure resistance and large leakage air tightness. Inspection (this feature is optional)
- Vacuum the inspected workpiece
- Fill the inspected workpiece with helium gas
- Vacuum box method helium mass spectrometry detection, automatically determine whether the leakage rate of the workpiece is qualified or unqualified
- Recover and recycle helium
- PLC control, touch screen operation, automatic detection
