Key points for maintaining the sealing performance of aerial vehicles

The operation of aerial vehicles is mainly due to the implementation of hydraulic systems. Therefore, drivers need to maintain and attach importance to aerial vehicles in addition to carrying out work. When carrying out maintenance work on the aerial work vehicles, it is necessary to put the sealing ring of the hole on the body through the harness and the body hole in place, because the role of the sealing ring not only plays a role in sealing, but also protects it. The role of the harness. Adding the seal ring is damaged or the wire harness is shaken in the seal ring. The sealable ring should be replaced in time, and the body holes, holes, and wiring harnesses should be firmly fixed.

After the window glass of the aerial work vehicle is damaged, it is necessary to replace it with a glass with the same curvature as the original window glass, and at the same time, check whether the guide groove of the glass and the sealing strip are damaged. Because the windows of the aerial vehicles are generally not restored to their original state after being repaired, so in addition to being able to ensure that the window glass can be lifted and lifted, it is also necessary to pay attention to the windows after they are closed. How tight is it?

When repairing a sealed-flanged door, it is important to pay attention to repairing the damaged sealing flange. It should be more accurate to restore the shape of the flange. After the repair of the door, attention should be paid to the inspection of the seal. We placed a piece of cardboard in a sealed position, closed the door, pulled the lower piece, and judged how effective the sealing was based on the magnitude and magnitude of our pulling force. If the force required to pull a piece of paper is relatively large, then it means that the seal is relatively tight. This will directly affect the closing of the door, and even cause the seal to be deformed too quickly. Loss of sealing performance. If you pull the paper, the force is relatively small. It also shows that the sealing effect is not good, the car door can not stop the wind and rain. When replacing the doors, it should be noted where the edges of the inner and outer plates of the new doors are to be removed, and some of the small holes left in the stamping process should be sealed with the base tape.

When changing the roof, it is necessary to first apply a layer of conductive sealant to the press-bonding area around the roof, and wait for the welding to be performed on the edge of the joint in the gutter and on the edge of the seam. It is to facilitate the sealing of the body and even prevent the early corrosion of the body of the aerial work vehicle due to the accumulation of water in the flanged seam. When carrying out the refitting door, it is necessary to paste a large sealing isolation film on the inner door panel below the parking lot. If it is a molded sealing film, it can be replaced by ordinary plastic paper. , and then press the seal across the mask, and finally use the inner trim plate to be assembled. (Text / Sun Ni)
