I. Performance Features
● Fills the test workpiece with high-pressure nitrogen for pressure resistance and gross leak airtightness testing (this function is optional);
● Vacuum chamber helium mass spectrometry detection, automatically determines whether the workpiece leak rate is qualified or unqualified;
● Recovers and recycles helium gas;
● PLC control, touchscreen operation, fully automatic detection;
● Helium gas recovery and recycling;
● Test pressure up to 5.0 MPa, cycle time ≤30 seconds per piece;
● Equipment features automatic background monitoring and purging functions;
● Helium detection sensitivity: 5.0×10-7 Pa·m³/s.
II. Product Overview
Suitable for leak detection of high-pressure air conditioning pipelines and other products in the refrigeration industry. It adopts the method of filling helium inside the chamber and detecting inside the chamber, ensuring a reliable safety factor. The equipment uses a helium mass spectrometry leak detector, offering high detection accuracy and low false detection rates, meeting the customer's high-precision detection requirements at an annual leak rate of -7 level. It can test multiple pieces in one chamber and also implements blockage detection functionality.
