AI Technical Summary
Traditional testing methods cannot effectively detect defects such as tiny cracks and pores inside rubber O-rings, leading to inaccurate judgments of sealing performance.
The detection mechanism consists of a base, a fixed sealing detection cylinder, a movable sealing detection cylinder, and a pressure sensor. A fixed pressure is injected by an air compressor, and the pressure sensor monitors the pressure changes in the cavity in real time to determine the sealing performance of the rubber O-ring.
It enables precise testing of the sealing performance of rubber O-rings, effectively identifies internal defects, and improves the accuracy and reliability of testing.
