在修理汽车线路时,应将所有车身孔、洞处穿线束的密封圈装到位,因为这些密封圈不仅起密封作用,而且还起保护线束的作用。济南自动变速箱维修讲解如果密封圈已经损坏或线束能在密封圈中转动或窜动,应更换密封圈,并将它与车身孔、洞装配牢固,将线束稳固好。

When repairing the automobile circuit, all the sealing rings through the harness at the body holes and holes should be installed in place, because these sealing rings not only play the role of sealing, but also play the role of protecting the harness. Jinan automatic gearbox maintenance explanation if the sealing ring has been damaged or the harness can rotate or move in the sealing ring, the sealing ring should be replaced, and it should be firmly assembled with the body hole and hole to stabilize the harness.

在车窗玻璃损坏后,要换用与原车窗玻璃曲率一样的玻璃,同时要检查玻璃导槽及密封条有无损伤。由于车窗经过修理后往往回复不到原来的形状,因此,这时除了要保证能轻松拉动或升降车窗玻璃外,还要注意在车窗关闭后车窗玻璃四周的密封性。

After the window glass is damaged, replace the glass with the same curvature as the original window glass, and check whether the glass guide groove and sealing strip are damaged. Since the window cannot return to its original shape after repair, it is necessary to ensure that the window can be easily pulled or lifted, and pay attention to the sealing around the closed window.

在修复有密封凸缘的车门时,应注意修复受损的密封凸缘,准确地恢复原凸缘的形状。在修复车门后要进行密封性检查,检查方法是:把一块硬纸片放在密封位置上,关上门,再拉动纸片,根据拉力的大小来判断密封是否良好。如果拉动纸片所需的力过大说明密封过紧,这会影响车门的正常关闭,并且还会使密封件因变形过大面较快地丧换密封性能;如果拉动纸片所需的力过小,说明密封不良,往往会出现车门挡风不挡雨的现象。在更换车门时一定要注意在新车门的内外板翻边咬合处涂折边胶,并把一些在冲压时留下的小工艺孔用本基胶带堵住。

When repairing the door with sealing flange, pay attention to repair the damaged sealing flange and accurately restore the shape of the original flange. After repairing the door, the sealing inspection shall be carried out. The inspection method is: put a piece of hard paper on the sealing position, close the door, pull the paper again, and judge whether the sealing is good according to the pulling force. If the force required to pull the paper is too large, it means that the seal is too tight, which will affect the normal closing of the door, and also cause the sealing performance of the seal to lose quickly due to the deformation of the large side; if the force required to pull the paper is too small, it means that the seal is poor, and the door will often be windproof and rainproof. When replacing the door, it is necessary to pay attention to the application of flanging glue at the joint of the inner and outer panels of the new door, and block some small process holes left during stamping with the basic tape.

济南奥迪专修提醒您在换车顶时,应先在车顶周边压合处涂一层导电密封胶,待焊好后再在流水槽内及接缝处遍涂折边胶,这不但有助于车身的密封,更可防止车身因翻边焊缝处积水而产生早期锈蚀。装配车门时要在车窗以下的车门内板上粘贴一整张密封隔离薄膜,如果没有成型的密封隔离薄膜,则可用普通塑料纸来替代,然后将密封隔薄膜贴上压实,更后再进行内饰板产装配。

Jinan Audi special repair reminds you that when changing the roof, you should first apply a layer of conductive sealant to the pressing joint around the roof, and then apply the folding adhesive to the water trough and the joint after welding, which not only helps the sealing of the body, but also prevents the body from early corrosion due to water accumulation at the flanging weld. When assembling the door, a whole piece of sealing and isolating film shall be pasted on the door inner panel below the window. If there is no formed sealing and isolating film, it can be replaced by ordinary plastic paper, then the sealing and isolating film shall be pasted and compacted, and the interior trim panel production and assembly shall be carried out later.
