AI Technical Summary
Existing general-purpose tank jacket pressure testing devices require frequent replacement of joints and seals due to the large differences in tank jacket dimensions. This results in long preparation times and a cumbersome process, making rapid testing impossible.
A universal tank jacket pressure testing device was designed, comprising a movable frame, a liquid pump, a liquid storage tank, a snap-fit mechanism, and a limiting mechanism. The snap-fit mechanism allows for quick connection of flanges of different diameters, and the limiting mechanism provides fixation, enabling rapid installation and sealing.
It enables rapid connection and fixation of flanges of different diameters, improves the installation efficiency and sealing performance of jacketed tests in tanks, and simplifies the test preparation process.
