Helium Sniffer Testing Equipment for Air Conditioning Condenser Evaporator Piping
According to the basic principles of helium leak detection, helium as a tracer gas, the workpiece will be filled with helium, and then through a helium leak detector leak can quickly and accurately determine the accuracy of the workpiece’s leakage.
Technical Parameters:
| Workpiece | Air conditioning piping / coils |
| Tracer Gas | Mixture helium & nitrogen (30% helium + 70% nitrogen) or pure helium |
| Leak Detection Rate | 2g/y, equal to 1x10-6Pa.m3/s |
| Leak detector setting accuracy | 1x10-8Pa.m3/s |
| Pressure for Gross Leak Detection | 4.0 Mpa (Downward adjustable) |
| Pressure for Fine Leak Detection | 4.0 Mpa (Downward adjustable) |
| Detection Method | Manually held sniffer |
| Evacuation/ filling/ recovery joint | 2 stations (independent), 2 connectors per station (only 1/4 thread, customer-supplied connector) |
| Test Cycle | 30s/pc (Excluding loading / unloading workpiece and hand-held sniffer detection time) |
| Test Bench | 1500mm*600mm |
| high-pressure hose | 1.5m (4 pcs) |
| Platform height | 850MM |
| Equipment Composition | Operation platform + Helium filling & recovery system (pipes for connecting the two parties are responsible for the customer) |
| Power Supply | Three-phase |
| Alarm | The system will alarm when the sniffer detects leakage signal |
System will sum all the leakage rate of all the leakage points automatically, if the total helium weight detected exceeds the preset range, that indicates the workpiece has a fine leak. In that case, the fine leak detection process is stopped; and the fine leakage and “NG” instructions are shown on the operation interface; operator should click “Confirm” on the operation board to acknowledge the test results; next process is continued.
If the total helium weight detected does not exceed the preset range, that indicates the workpiece is qualified, and the OK signal is given on the operation interface; next process is continued.
Workpiece is unloaded by operator manually
