Description

TECHNICAL FIELD

[0001] The present application relates to the field of gas tank detection, in particular to an immersion type air tightness testing equipment. BACKGROUND

[0002] In modern production and life, more and more clean energy is used as the energy source for production and daily use, and natural gas is the main clean energy used, which has many advantages such as clean emission, convenient storage and transportation, and large reserves. Current natural gas storage and transportation mainly rely on natural gas tanks, i.e. LNG tanks. However, the LNG tanks may be damaged due to bumping, production and assembly errors, etc. after long-term use or when leaving the factory, resulting in poor air tightness and causing certain safety hazards to the use of the gas tank. At present, the air tightness of the gas tank is mainly detected by two methods of gas pressure test and air tightness test by entering. The gas pressure test can only determine the air tightness performance of the gas tank, but cannot determine the damaged position, so it is not convenient for repair or determination of the damage reason. The current immersion type detection equipment cannot simultaneously detect a large number of gas tanks at one time, and the working personnel cannot conveniently observe the position of the bubbles in the liquid. When the gas tank enters the liquid, the disturbance of the liquid makes it very difficult to observe the bubbles.

[0003] Therefore, the present application designs an immersion type air tightness testing equipment which can fix and disassemble the barrel body, continuously stir by replacing the barrel body, and pre-place materials in the barrel body. CONTENT OF THE UTILITY MODEL
