1. Check whether there are large cracks or cracks in the seal of self feeding mixer. If the seal breaks, it can be repaired with adhesive. In particular, the use of special adhesives on seals can easily fill large crack areas. Of course, if the seal is seriously damaged or damaged, replace it with a new one.

2.在驾驶员用自上料混凝土搅拌罐车清洁门窗密封条之后，应涂一层渗透防护剂，以防止密封条老化，并显着提高密封条的密封性能。让我来。另外，密封条之间的间隙容易充满灰尘和锈蚀。为此，您需要使用刷子灰尘。

2. After the driver cleans the sealing strips of doors and windows with self feeding mixer, he should apply a layer of penetration protection agent to prevent the aging of the sealing strips and significantly improve the sealing performance of the sealing strips. Allow me. In addition, the gap between the sealing strips is easy to be filled with dust and rust. To do this, you need to use a brush to remove dust.

3.更换整个机身时，有必要在焊接部分的重叠部分涂一层密封剂。粘合剂层的厚度约为1毫米，不应有诸如粘合力差或气泡之类的缺陷。地板的整个底面和前轮盖的底面应涂3毫米4毫米的弹性涂层和防腐涂层。这些措施不仅显着提高了车身的密封性能，减缓了车身的腐蚀速度，而且大大提高了乘坐舒适性。

3. When replacing the whole fuselage, it is necessary to apply a layer of sealant on the overlap of the welding parts. The thickness of the adhesive layer is about 1 mm and there should be no defects such as poor adhesion or bubbles. The whole bottom surface of the floor and the bottom surface of the front wheel cover shall be coated with elastic coating and anti-corrosion coating of 3mm to 4mm. These measures not only significantly improve the sealing performance of the car body, slow down the corrosion rate of the car body, but also greatly improve the ride comfort.

4.密封门和门是一个相对困难的部分。密封要求相对严格。要密封的部分相对较长，每个密封部分的横截面形状都不相同，并且门经常被打开和关闭。在自上料混凝土搅拌罐车上安装3向和4向密封垫，并安装前立柱的4密封结构和顶梁的侧梁。这种多通道密封通常放置在前门之间的间隙中，除了具有密封功能外，还具有减少车辆噪音的作用。

4. Sealing the door and the door is a relatively difficult part. Sealing requirements are relatively strict. The parts to be sealed are relatively long, the cross-sectional shape of each sealing part is different, and the door is often opened and closed. Install 3-way and 4-way sealing gasket on concrete mixer truck, and install 4-way sealing structure of front column and side beam of top beam. This kind of multi-channel seal is usually placed in the gap between the front doors, which not only has the sealing function, but also has the function of reducing vehicle noise.

5.窗户玻璃损坏后，驾驶员应在更换玻璃时检查密封条是否损坏。维修后，窗户通常不会恢复其原始形状，因此，除了能够轻松地拉起和提起窗户玻璃外，还应注意窗户玻璃周围的密封性。如果玻璃和玻璃容器之间的间隙不均匀，则橡胶条在玻璃和玻璃容器之间的接触不良，并且驱动器很容易用手拉动密封环。

5. After the window glass is damaged, the driver should check whether the sealing strip is damaged when replacing the glass. After maintenance, the window usually does not return to its original shape. Therefore, in addition to being able to easily pull up and lift the window glass, attention should also be paid to the sealing around the window glass. If the gap between the glass and the glass container is not uniform, the rubber strip has poor contact between the glass and the glass container, and the driver can easily pull the sealing ring by hand.

6.更换车顶时，驾驶员必须先压装并在车顶周围涂上一层导电密封胶。焊接后，在流道和接头上涂抹折边胶。这不仅有助于身体。密封件可防止由于法兰焊缝中积水而导致的汽车过早腐蚀。

6. When replacing the roof, the driver must first press fit and apply a layer of conductive sealant around the roof. After welding, apply flanging glue on the runner and joint. It's not just good for the body. The seal can prevent the premature corrosion of the automobile caused by the water accumulated in the flange weld.

7.自上料混凝土搅拌罐车的天窗是大多数家庭用车的基本配置。当您打开汽车的天窗时，橡胶密封导轨会暴露在空气中，这不可避免地会积聚灰尘甚进入小砾石中。长期使用后，天窗可能会因磨损而变形，排水口可能会堵塞。因此，定期清洁叉车并润滑叉车非常重要。

7. The skylight of concrete mixer is the basic configuration of most family cars. When you open the car's skylight, the rubber sealing guide rail will be exposed to the air, which will inevitably accumulate dust and even enter the small gravel. After long-term use, the skylight may be deformed due to wear, and the drain may be blocked. Therefore, it is very important to clean and lubricate the forklift regularly.
