Vacuum Chamber Helium Leak Detection System for Heat Exchanger
This helium leak test equipment is made according to the base working principle: helium as a tracer gas, the workpiece will be filled with helium in the vacuum chamber, and then through a helium leak detector leak can quickly and accurately determine the accuracy of the workpiece’s leakage.
Main Techincal Parameters:
| Test Workpiece | Heat Exchanger |
| Vacuum Chamber | 1 |
| Vacuum Chamber Dimension | According to the actual workpiece dimension, no more than 1300L |
| Number of Workpiece per Chamber | 1 |
| Workpiece Connection Method | Fixture positioning, joint sealing |
| Leakage Rate | 1g/a |
| Test Cycle | 6min/pc (Time from chamber door closed to opened) |
| Gas for Gross Leakage Detection | Nitrogen |
| Pressure for Gross Leakage Detection | 4.0Mpa (Downwards adjustable) |
| Gas for Fine Leakage Detection | Helium (>99.99%) |
| Pressure for Fine Leakage Detection | 4.0Mpa (Downwards adjustable) |
| Connection between Workpiece and Vacuum Chamber | The operator plugs one end of the workpiece with a special plug, and seals the other end of the workpiece with a special connector. After the workpiece is transferred into the vacuum chamber, the special sealed male connector of the workpiece is connected to the quick female connector in the vacuum chamber. |
| Helium Recovery | Automatic recycling system, helium recovery rate≥98% |
