Automotive Air - conditioning Compressor Vacuum Helium Detection System Air Tightness Test Equipment
The system is suitable for automotive air-conditioning compressor air-tightness testing, but also suitable for testing the sealing performance of the refrigerators, air-conditioning's compressors, to avoid the leakage of hazardous materials. This test system is available for manufacturer's mass production detection applicated in production line.
Principle and structure:
According to the basic leak detection principle of helium, with helium as the tracer gas, the workpiece is placed in the vacuum chamber and filled helium into it, then through the helium leak detector can quickly and accurately determine the accuracy of the workpiece‘s leakage. The system uses four vacuum chambers, the operator will place the workpieces into the vacuum chambers, connect the workpiece's interface with the quick connector. After the vacuum chamber door is closed, the system can automatically complete the large leak and strength detection, vacuum, filling in helium, fine leak detection, helium recovery and other procedures. The whole test cycle is fast and high precision.
