AI Technical Summary
Existing methods for detecting leaks in heat exchange tubes are inefficient, cumbersome to operate, and prone to misjudgment. Furthermore, common devices are not properly sealed or easily damage the tube openings, failing to meet the requirements for efficient and accurate detection.
The heat exchanger tube rapid airtightness testing equipment adopts the multi-channel differential pressure method. It achieves flexible position adjustment through adjustment components, uses an expansion sealing head to adapt to the pipe diameter, and combines a differential pressure sensor and a self-test calibration block to achieve reliable sealing, rapid detection, and intuitive display of results.
It improves detection efficiency and accuracy, adapts to heat exchanger tube arrays of different sizes and spacings, requires no equipment replacement, is undamaged during the sealing process, and its self-testing function ensures that the system makes no misjudgments, significantly improving the versatility and reliability of the detection.
