    water. (2) Method of testing water test: 1 Place the inner tube in the water tank, put the rubber hose on the valve, and fill the inner tube with compressed air until it is free from wrinkles and reach its normal specifications.
    (1) Place the inner tube on the fitter, check it carefully, and mark the wound on the found day. For the inner tube of the wound that cannot be found by the naked eye, test the water.
    (2) Method of testing water test:
    1 Place the inner tube in the water tank, put the rubber hose on the valve, and fill the inner tube with compressed air until it is free from wrinkles and reach its normal specifications.
    2 Partially fill the air-filled inner tube into the water tank (water tank diameter 1200-1300mm, height 600-700mm, the device is in a fixed place, a snake-shaped steam pipe can be set at the bottom of the water tank, and the water temperature can be raised to 25 by steam when needed. -30 ° C, and a water drain switch), press it with a hand or a special pneumatic clamp to check if air bubbles emerge from the inner tube wound.
    3 Then remove the inner tube, use a color pen to circle the wound at the leak, and then sink the inner tube into the water to find the remaining 'hidden wounds.
    4 After inspection, the inner tube should be hung on the rack for drying.
    (3) Determine the repairability of the inner tube
    When the inner tube has one of the following conditions, it may not be repaired.
    1The rubber has aged, and when there is crack when bending,
    2 is the rust of the wheel phase,
    If the length of the crack is more than 500mm and the width is greater than 50mm (the inner tube can be repaired by the inlay method, the damaged part is replaced with a good one).
    4 has been attacked by oil, acid, alkali and other materials that damage rubber.
