Vaccum Helium Leak Testing Equipment for Automotive Air Conditioning Pipeline
This system is suitable for air-tightness detection of air conditioning pipeline, Fuel lines, brake oil pipeline and engine pipeline of automobile.
Technical parameters
| Workpiece | Automotive air conditioning pipeline |
| Vacuum chamber | 2 , customized according to product |
| Tracer gas | Helium |
| Gas pressure for leak detection | 2 - 42Bar (Downward adjustable) |
| Reject point | 2g/Year ( R134a ) |
| Cycle time | 30s / pc |
Test 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.
Operation Structure
The system has 2 vacuum chambers. The operator puts the workpiece and seals it with a fixture in the vacuum, chamber. 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. High precision, easy operation and fast test cycle make our helium leak test system is widely adopted by manufacturers.
