There are two methods for concrete self mixing truck, oil brake and air brake. This is everyone's technical question: why use air brakes?

空气制动器反应迅速，制动器粗糙，力很大（气压高，可达到8个大气压）。

The air brake responds quickly, the brake is rough and the force is very large (the air pressure is high, up to 8 atmospheres).

除制动主缸，副泵和制动管路外，空气制动器还有一个气泵（通过皮带连接到发动机），一个储气缸，一个高压控制器（调节压力，车辆）这些部件需要大的安装空间和复杂的结构，并且为了确保性，后制动缸现在是气体制动器（成本增加且结构复杂）。

In addition to the brake master cylinder, auxiliary pump and brake pipeline, the air brake also has an air pump (connected to the engine by belt), an air reservoir and a high-pressure controller (regulating pressure, vehicle). These components require large installation space and complex structure. In order to ensure safety, the rear brake cylinder is now a gas brake (increased cost and complex structure).

因此，由于这些原因，一般的油刹大多是中小型车。它们体积小，结构简单，并且在自己的车辆中很轻。他们不需要太多力量。近年来，出现了中型车辆（载重量低于10吨，约为19辆）的趋势。座椅下方的中型客车都配备了油刹车。大多数空气制动器用于大型卡车，公共汽车和混凝土搅拌车。车辆空间大，所需制动力大，使用距离长，反应速度快，增加的成本不反映在整车的比例上。

Therefore, due to these reasons, most of the general oil brakes are small and medium-sized vehicles. They are small, simple in structure and light in their own vehicles. They don't need much strength. In recent years, there has been a trend of medium-sized vehicles (carrying capacity less than 10 tons, about 19 vehicles). The medium-sized buses under the seats are equipped with oil brakes. Most air brakes are used on large trucks, buses and concrete mixers. The vehicle has large space, large braking force, long service distance and fast response speed. The increased cost is not reflected in the proportion of the whole vehicle.

混凝土自拌车的保养注意事项

Precautions for maintenance of concrete self mixing truck

通常，当我们使用混凝土自拌车时，我们希望更好地操作设备并保持设备的良好性能。我们需要很好地维护混凝土自拌车。但是，在维护过程中有一定的预防措施。让我们简要了解一下：

Generally, when we use concrete self mixing truck, we want to better operate the equipment and maintain the good performance of the equipment. We need to maintain the concrete truck well. However, there are certain preventive measures in the maintenance process. Let's take a brief look:

1.清洁机器时，只能擦拭电箱，不能冲洗电箱。

1. When cleaning the machine, only wipe the electric box, not flush the electric box.

2.调整主轴密封圈，必须拆下泵芯和进给支架，然后拧紧三颗螺钉。拧紧螺钉后的标准：8英寸可动手可以轻松拉动主轴螺钉。

2. To adjust the main shaft sealing ring, the pump core and feed support must be removed, and then tighten three screws. Standard after tightening the screw: 8-inch hands-on, easy to pull the spindle screw.

3.在施工现场移动机器时，无论距离多远，都必须拔下电源线。

3. When moving the machine at the construction site, no matter how far away it is, the power cord must be unplugged.

4.机器工作时，必须关闭并锁上电箱门，以防止灰尘和湿气侵入并损坏机器组件。

4. When the machine is working, the electric box door must be closed and locked to prevent dust and moisture from invading and damaging the machine components.

5.在工作前后，必须给轴承箱加油，并应经常检查齿轮箱油。

5. Before and after work, the bearing box must be filled with oil, and the gearbox oil shall be checked frequently.

6.每次清洗泵芯时，都必须加一点硅油润滑和抗刺绣作用。目的是防止旋转铁芯生锈，并在下次使用后平稳启动。

6. Each time the pump core is cleaned, a little silicone oil must be added for lubrication and anti embroidery effect. The purpose is to prevent the rotating iron core from rusting and start smoothly after next use.

混凝土自拌车采用全液压技术，因此要考虑所有液压技术是否以及液压视觉质量。因为动力来自发动机，所以除了要考虑发动机的性能和质量外，还必须考虑底盘的性能，承载能力和质量。在维修车辆设备的过程中，必须严格按照正确的操作过程进行操作，以保持效果。

The concrete self mixing truck adopts full hydraulic technology, so whether all hydraulic technologies are advanced and hydraulic visual quality should be considered. Because the power comes from the engine, in addition to the performance and quality of the engine, the performance, bearing capacity and quality of the chassis must also be considered. During the maintenance of vehicle equipment, the correct operation process must be strictly followed to maintain the effect.

混凝土自拌车为什么要用气刹制动的介绍就是这样了，希望对你有帮助。

This is the introduction of why the concrete self mixing truck should use air brake. I hope it will be helpful to you.
