Car maintenance knowledge teaches you how to protect sealing performance

Automobile maintenance knowledge teaches you how to protect the sealing performance. When repairing the car circuit, you should install all the car body holes and holes through the sealing ring of the wiring harness in place, because these sealing ring mechanical seal factories not only play a sealing role, but also protect the wiring harness effect. If the sealing ring is damaged or the wiring harness can rotate or move in the sealing ring, replace the sealing ring and assemble it firmly with the holes and holes of the vehicle body to stabilize the wiring harness. After the window glass is damaged, it should be replaced with glass with the same curvature as the original window glass. At the same time, the seal factory should check the glass guide groove and the sealing strip for damage. Since car windows often fail to return to their original shape after being repaired, in addition to ensuring that the car window glass can be easily pulled or lifted, it is also necessary to pay attention to the airtightness around the car window glass after the car window is closed. When repairing a car door with a sealing flange, attention should be paid to repairing the damaged sealing flange and accurately restoring the shape of the original convex pump mechanical sealing flange. After repairing the door, check the seal. The inspection method is: put a piece of hard paper on the sealing position, close the door, and then pull the paper to judge whether the seal is good or not according to the magnitude of the pulling force. If the force required to pull the paper sheet is too large, it means that the seal is too tight, which will affect the normal closing of the door, and it will also cause the seal to lose its sealing performance quickly due to excessive deformation; if the force required to pull the paper sheet If it is too small, it means that the seal is not good, and the door will often block wind but not rain. When replacing the door, be sure to apply hemming glue at the flanging occlusion of the inner and outer panels of the new door, and block some small craft holes left during punching with the base tape. When changing the roof, apply a layer of conductive sealant on the periphery of the roof. After the welding is completed, apply hemming glue all over the water trough and at the joints. This will not only help seal the body, but also It can also prevent the car body from being rusted early due to the accumulation of water at the flanging weld. When assembling the car door, paste a whole sealing isolation film on the inner door panel below the window. If there is no formed sealing isolation film, it can be replaced by ordinary plastic paper, then the sealing isolation film is pasted and compacted, and finally Production and assembly of interior trim panels. When replacing the entire car body, in addition to completing the above items, a layer of sealant should be applied to the overlapped part and solder joints of the weld. The thickness of the adhesive layer should be about 1mm, and the adhesive layer must not have any virtual stickiness. Defects such as, air bubbles, etc.; special hemming glue should be applied at the fold; 3mm-4mm elastic coating and anti-corrosion coating should be applied to the entire lower surface of the floor and the lower surface of the front wheel cover; on the upper surface of the floor and the front stand The inner surface of the board should be pasted with sound insulation, heat insulation, vibration damping and damping film, and then covered with insulation felt, and finally covered with carpet or decorated floor. These measures can not only greatly enhance the airtightness of the vehicle and slow down the corrosion rate of the car body, but also greatly improve the ride comfort.
