This equipment is designed to detect the airtightness of the welded end of the bottom cover and the

peripheral welded parts of the automobile shock absorber liquid storage cylinder assembly. The leak test type is a horizontal full submersible type. After passing through the sealed port, the entire workpiece is submerged in water, and then compressed air is filled into the assembly. The welding workpiece's airtightness is judged by observing whether there are bubbles overflowing on the water surface. The time for sinking, airtightness

detection, and control can be adjusted using a hand pull switch.
