Two Detection Staons Helium Leak Testing Equipment for Automotive Expansion Valve

This equipment has 2 vacuum chambers. The operator puts the workpiece into the fixture in the vacuum chamber, then turn on the button and the fixture automatically seals the piecework. After the door of vacuum chamber is closed, the system can automatically complete the whole process like large leakage and strength detection, air exhaust, helium filling, Fine leak detection, helium removal and so on. High precision, easy operation and fast test cycle make our helium leak test system is widely adopted by pressure sensor core manufacturers.

Technical Specification

Equipment Application

According to the basic principle of helium leak detection, with helium as the tracer gas (instead of Freon), 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.

This system is suitable for air-tightness detection of automotive air-conditioning expansion valve. It ensures the airtightness of the product and avoid the leakage of harmful substances (refrigerant).
