Did you check the seal when you used the suction truck or suction truck?

When repairing the roof

When changing the roof of the suction truck and suction truck, firstly apply a layer of conductive sealant at the pressure joint of the roof, and then apply the folded edge glue in the flow tank and seams after welding. This is not only Contributes to the sealing of the body and prevents the body from causing early corrosion due to the accumulation of water at the flange weld. When assembling the door, it is necessary to affix a whole piece of sealing and isolating film on the inner panel of the door below the window. If there is no formed sealing isolation film, ordinary plastic paper can be used instead, and then the sealing and film is affixed and compacted. Interior panel production assembly.

When repairing windows

After the suction truck and suction draught vehicle window glass are damaged, the glass with the same curvature as the original window glass should be replaced, and at the same time, check whether the glass guide groove and the sealing strip are damaged. Since the windows do not always return to their original shape after repair, it is also necessary to ensure that the window glass can be sealed tightly after the window is closed, in addition to ensuring that the window glass can be easily pulled or lifted.

When repairing the door

When repairing a door with a sealing flange, care should be taken to repair the damaged sealing flange and accurately restore the original flange shape. Check the seal after repairing the door.

The inspection method is: Put a piece of hard paper in the sealed position, close the door, and then pull the paper, according to the size of the pull to determine whether the seal is good. If the force required to pull the paper piece is too large to indicate that the seal is too tight, this will affect the normal closing of the door, and will also cause the seal to change its sealing performance quickly due to deformation over large surfaces;

The force required to pull a piece of paper is too small, indicating that the seal is poor, and the door wind is often not protected from rain. When replacing the door, it is necessary to pay attention to the folding edge glue on the inner and outer flanges of the new door, and to plug some of the small holes left in the punching process with the base tape.

When repairing sewage suction vehicles and suction truck lines

When repairing sewage suction trucks and suction trucks, all the holes in the body holes and holes in the holes should be put in place because these sealing rings not only function as seals, but also serve as protective harnesses. If the sealing ring is damaged or the wire harness can rotate or shake in the sealing ring, replace the sealing ring, and assemble it firmly with the body holes and holes to stabilize the wire harness.

When replacing the body

When replacing the entire vehicle body, besides the above items, the seals should be applied to the overlapping parts of the welds and the solder joints. The thickness of the adhesive layer should be approximately 1mm, and the adhesive layer should not be viscous. Defects such as bubbles, etc.; special hemming adhesives should be applied on the folds; 3mm-4mm elastic coating and anti-corrosion coating should be applied on the underside of the entire floor and the front surface of the front wheel cover; The inner surface of the board is to be affixed with sound-insulating, heat-insulating, vibration-damping film, then covered with heat-insulating mats, and finally carpeted or decorated with a decorative floor. These measures can not only greatly enhance the vehicle's tightness and reduce the rust speed of the body, but also can greatly improve the ride comfort.
