Daily maintenance of sealant strip of automatic feeding concrete mixer

1、检查自动上料混凝土搅拌车密封条有无大的裂纹，有无断裂。如果密封条断裂了，可以使用粘结剂进行修补。特别是使用密封条专用粘结剂，很容易就能把大的裂纹条补好。当然，如果密封条损伤严重，或老化程度较大，还是更换新密封条省事。

1. Check whether the sealing strip of the automatic feeding concrete mixer has large cracks and fractures. If the sealing strip breaks, it can be repaired with adhesive. In particular, the use of special adhesive for sealing strip can easily repair the large crack strip. Of course, if the seal is seriously damaged or aging, it is easy to replace it with a new seal.

2、司机在使用自动上料混凝土搅拌车洗涤剂进行清洗门窗密封胶条之后，涂覆一层高渗透性的保护剂，这样既能防止密封条老化又能提高密封条的密封性。除此之外，密封条的缝隙之间很容易塞满沙尘，从而引发锈蚀。为此，应该用刷子把沙尘等清除干净。

2. The driver shall apply a layer of high permeability protective agent after cleaning the door and window sealant strip with the detergent of automatic feeding concrete mixer, which can not only prevent the aging of the sealing strip, but also improve the sealing performance of the sealing strip. In addition, the gaps between the sealing strips are easy to be filled with sand and dust, resulting in corrosion. Therefore, the sand and dust should be removed with a brush.

3、在更换整个车身时，应在焊缝的搭接部分涂一层密封胶，胶层厚度应约为1mm，并且胶层不得有虚粘、气泡等缺陷。在整个地板下表面和前轮罩下表面应涂3mm-4mm的弹性涂层及防腐涂层。

3. When replacing the whole vehicle body, a layer of sealant shall be applied to the overlapping part of the weld. The thickness of the adhesive layer shall be about 1mm, and the adhesive layer shall be free of defects such as virtual adhesion and bubbles. 3mm-4mm elastic coating and anti-corrosion coating shall be applied on the lower surface of the whole floor and the lower surface of the front wheel housing.

自动上料混凝土搅拌车密封胶条怎么维护？

How to maintain the automatic feeding of sealant on the concrete mixer?

4、车门与车身的密封是一个比较困难的部位，密封要求比较严，应密封的部分比较长，各密封部位的断面形状不尽相同，而且车门启闭频繁。在自动上料混凝土搅拌车上常设置3道,4道密封，安装前支柱及车顶侧横梁部位的四重密封的构造。这种多道密封一般都布置在前门缝里，除具有密封功能外，还有汽车隔音降噪的作用。

4. The sealing of door and vehicle body is a difficult part. The sealing requirements are relatively strict. The part to be sealed is relatively long. The section shapes of each sealing part are different, and the door is opened and closed frequently. Three and four seals are often set on the automatic feeding concrete mixer, and the structure of four seals at the front pillar and roof side beam is installed. This multi-channel seal is generally arranged in the seam of the front door. In addition to the sealing function, it also has the function of automobile sound insulation and noise reduction.

5、在车窗玻璃损坏后，司机在换用玻璃时，要检查密封条有无损伤。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，还要注意车窗玻璃四周的密封性。如果玻璃同玻璃槽口的缝隙不均，橡胶条与玻璃、玻璃槽接触不良，司机可以用手能轻易地将密封条拉脱。

5. After the window glass is damaged, the driver shall check whether the sealing strip is damaged when changing the glass. Because the window can not return to its original shape after repair, in addition to ensuring that the window can be easily pulled or lifted, pay attention to the sealing around the window. If the gap between the glass and the glass slot is uneven, and the rubber strip has poor contact with the glass and glass slot, the driver can easily pull off the sealing strip by hand.

6、司机在换车顶时，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。

6. When changing the roof, the driver should first apply a layer of conductive sealant at the compression joint around the roof, and then apply the folding adhesive in the water channel and the joint after welding, which not only helps to seal the body, but also prevents the body from early corrosion due to ponding at the flanging weld.

7、自动上料混凝土搅拌车天窗是大多数家用轿车的基本配置。当汽车天窗打开时，橡胶密封条轨道暴露在空气中，难免堆积粉尘，甚至跑进小沙砾。长时间使用可能导致天窗因磨损而变形，并堵塞排水孔。所以定期清理轨道，为轨道涂抹润滑油十分重要。

7. The skylight of automatic loading concrete mixer is the basic configuration of most family cars. When the car sunroof is opened, the rubber sealing strip track is exposed to the air, which will inevitably accumulate dust and even run into small gravel. Prolonged use may cause the sunroof to deform due to wear and block the drain hole. Therefore, it is very important to clean the track regularly and apply lubricating oil to the track.

自动上料混凝土搅拌车密封胶条虽是车身内的小部件，但是它能保证开关车门沉稳厚重，还能使车内避风雨、防尘、隔热、隔音，对门窗交接的边缘起到装饰的效果。当车身受到振动与扭曲时，密封条还起到缓冲、吸震、保护玻璃的作用。因此，自动上料混凝土搅拌车保养无小事，任何一个环节都不容忽视。

Although the sealant strip of automatic feeding concrete mixer truck is a small part in the car body, it can ensure the stability and massiness of opening and closing the door. It can also make the car weatherproof, dustproof, heat insulation and sound insulation, and play a decorative effect on the edges of door and window joints. When the vehicle body is vibrated and twisted, the sealing strip also plays the role of cushioning, shock absorption and glass protection. Therefore, there is no trivial matter in the maintenance of automatic feeding concrete mixer, and any link can not be ignored.
