The small commercial concrete automatic mixer includes truck chassis, mixing drum, transmission system, water supply, full power output, front and rear bracket of mixing bucket, reducer, hydraulic transmission system, air supply / exhaust system and operating mechanism. Unlike large self-propelled vehicles, most of the four components required for this technology are imported.

该车有两种类型的底盘：传动系，液压系统，框架，混合罐，给水和卸载装置，供水系统和操作系统。混合罐的前端连接到减速器并连接到机架的前部。后端由两个滚轮支撑，滚轮通过滚道连接到机架的后部。

There are two types of chassis: drive train, hydraulic system, frame, mixing tank, water supply and unloading device, water supply system and operation system. The front end of the mixing tank is connected to the reducer and to the front of the frame. The rear end is supported by two rollers, which are connected to the rear of the frame through the raceway.

高温下小型商砼自动搅拌车的维护

Automatic maintenance of small concrete mixer under high temperature

1，防止发动机机体过热：由于环境温度较高，发动机容易过热。有必要加强发动机冷却系统的检查和维护。这包括检查水箱，恒温器，水泵，风机等，并注意及时添加。注意冷却水。当水温超过100°C时，停在阴凉处冷却，让发动机怠速，并打开引擎盖以帮助散热。

1. Prevent engine body from overheating: due to high ambient temperature, the engine is easy to overheat. It is necessary to strengthen the inspection and maintenance of engine cooling system. This includes checking the water tank, thermostat, water pump, fan, etc., and paying attention to timely adding. Pay attention to the cooling water. When the water temperature exceeds 100 ° C, stop in the shade to cool, let the engine idle, and open the hood to help heat dissipation.

2，防止发动机爆燃：夏季气温高，有时超过35°C，而在这样的季节，对于部分老化部件的汽车，所以要做好预防准备。

2. Prevent engine deflagration: the temperature is high in summer, sometimes exceeding 35 ° C. in such a season, for vehicles with some aging parts, it is necessary to prepare for prevention.

3，防止汽车油漆损坏：汽车油漆经过强烈阳光照射后，会老化，起皱，而普通美容打蜡可以起到一定的防晒效果，但因为任何车蜡都含有铋成分，长时间紫外线照射会使油漆生锈留下一点黑点。汽车蜡本身不能提高硬度和抗紫外线效果，但它会因高温而迅速失去。停车时，请注意将车停在阴凉处。

3. Prevent the damage of automobile paint: the automobile paint will be aged and wrinkled after being exposed to strong sunlight, while the ordinary beauty waxing can have a certain sun protection effect, but because any car wax contains bismuth, long-term ultraviolet radiation will make the paint rust and leave a little black spots. Car wax itself cannot improve the hardness and UV resistance, but it will lose rapidly due to high temperature. When parking, please park in the shade.

4，防止汽车轮胎爆裂：高温时，更容易穿刺，当温度过高时，轮胎容易变形，抗拉强度降低。作为轮胎本身，气压不是标准的，轮胎老化，性能减弱，或者轮胎在行驶过程中被卷成硬质金属或其他硬物，这将导致汽车突然爆裂。

4. Prevent automobile tire burst: it is easier to puncture at high temperature. When the temperature is too high, the tire is easy to deform and the tensile strength is reduced. As the tire itself, the air pressure is not standard, the tire aging, performance degradation, or the tire is rolled into hard metal or other hard objects during driving, which will cause the car to burst suddenly.

5，防止发动机润滑不良：当温度高时，油的粘度降低，抗氧化性变差，导致润滑不良。因此，请务必检查油品质量并及时添加或更换。注意及时清洁机油滤清器和散热器，确保油流畅通，散热好，尽量避免发动机过载。

5. Prevent the engine from poor lubrication: when the temperature is high, the viscosity of the oil will be reduced, and the oxidation resistance will be poor, resulting in poor lubrication. Therefore, please check the quality of the oil and add or replace it in time. Pay attention to clean the oil filter and radiator in time to ensure smooth oil flow and good heat dissipation, and try to avoid engine overload.
