Vacuum Chamber Helium Leak Testing Equipment for automotive Evaporator Condenser
Operating principle
According to the basic principle of helium leak detection, with helium as the tracer gas, helium is filled into the workpiece in the vacuum chamber, and then the helium leak detector can accurately and quickly judge the leakage of the workpiece.
Application
This system is suitable for air-tightness detection of evaporators and condensers of automotive air-conditioner. It can also be used for evaporator, condenser of household refrigerator and air-conditioner to ensure the airtightness of the product and avoid the leakage of harmful substances (refrigerant).
Technical Parameters
| Workpiece | Evaporator, Condenser |
| Size of Vacuum Chamber | (L)1200mm×(W)200mm×(H) 600mm |
| Vacuum chamber | 2, each chamber can detect 2 workpieces at the same time |
| Tracer gas | Helium |
| Helium Pressure for Indicating Leakage | 2.0Mpa(Downward adjustable) |
| Gas pressure for gross leak | 3.0MPa (Downward adjustable) |
| Reject point | 2g/Year(R134a) |
| Cycle time | 2chambers work linkage, average 20s/pc |
| Helium Recover Rate | ≥98% |
Work procedure
The system has 2 vacuum chambers, each chamber with 6sets of quick connectors. The operator puts the workpiece in the vacuum chamber, then connects the workpiece interface with the quick connector. After the door of vacuum chamber is closed, the system can automatically complete the whole process like gross leakage and strength detection, air exhaust, helium filling, fine leak test, Helium recovery and so on.
Equipment Features
1 . High precision, easy to operate.
2 . Fast test cycle, average 20s/pc includingload and unload time.
3. With helium recovery deivce, save the using cost of helium.
4 . Nice appearance, Automatic operation.
