The engine of self loading concrete mixer can run normally, and the machine can work with high energy, mainly relying on the fuel system to provide power. Most of the time, the engine can't start or can't start because of the fault of the fuel system. Therefore, the daily maintenance of the fuel system should be done well. How to do it well?

1、及时加注燃油

1. Fill the fuel in time

小型自动上料搅拌车作业的过程中，操作人员要随时关注燃油量。当燃油表显示的燃油量接近“0”位时，一定要及时加注燃油。切忌等燃油用尽之后才添加，这样做的后果不仅仅是造成柴油机无油后熄火，重要的是会导致空气进入燃油系统。一旦燃油系统中进入了空气，不仅浪费了燃油，而且排出去比较麻烦。

During the operation of small automatic feeding mixer, the operator should pay attention to the fuel quantity at any time. When the fuel quantity shown on the fuel gauge is close to "0", be sure to fill the fuel in time. Do not add the fuel until it is used up. The consequence of this is not only to cause the diesel engine to stop when there is no fuel, but also to cause air to enter the fuel system. Once the air enters the fuel system, it not only wastes the fuel, but also causes trouble in discharging it.

2、注意避免燃油系统堵塞

2. Pay attention to avoid fuel system blockage

我们都知道，有时候自动上料搅拌车的工作环境比较特殊，这样就很容易导致燃油系统堵塞，一旦燃油系统堵塞，就会影响机器的正常运转。所以要及时检查确保燃油管道的通畅。

We all know that sometimes the working environment of the automatic feeding mixer is special, which can easily lead to the blockage of the fuel system. Once the fuel system is blocked, the normal operation of the machine will be affected. Therefore, it is necessary to check in time to ensure that the fuel pipe is unobstructed.

3、注意检查燃油系统密封性

3. Pay attention to check the tightness of the fuel system

小型自动上料搅拌车作业的时候，如果发现排气管冒黑烟，或是发动机出现启动困难的状况，有可能是因为漏气，所以要注意检查燃油系统的密封性。

During the operation of small automatic feeding mixer, if it is found that the exhaust pipe is emitting black smoke, or the engine is difficult to start, it may be due to air leakage, so pay attention to check the tightness of the fuel system.
            

4、保持燃油的清洁

4. Keep the fuel clean

燃油系统的故障有大约50%是因为燃油不洁所造成，对于汽油机而言，绝大多数是因为燃油中混入水分，汽油中的水分还会腐蚀和破坏燃油供油系统元件。

About 50% of the faults in the fuel system are caused by unclean fuel. For gasoline engines, most of them are caused by water in the fuel, which will corrode and damage the components of the fuel supply system.

5、燃油选择很关键

5. Fuel selection is key

建议选择适合自动上料搅拌车的高品质燃油，质量较差的燃油过滤不良，油泥、杂质、水分，长期积累，沉淀下来，容易堵塞油泵滤网，油管及喷油嘴。

It is suggested that high quality fuel suitable for automatic feeding mixer should be selected. The fuel with poor quality has poor filtration, sludge, impurities and moisture can accumulate and precipitate for a long time, which is easy to block the filter screen, oil pipe and nozzle of oil pump.

自上料混凝土搅拌车这类卡车上都装置圆筒型的搅拌筒以运载混合后的混凝土。在运输过程中会始终保持搅拌筒转动，以保证所运载的混凝土不会凝固。运送完混凝土后，通常都会用水冲洗搅拌筒内部， 防止硬化的混凝土占用空间。

Since the loading concrete mixer truck, such trucks are equipped with cylindrical mixing drum to carry the mixed concrete. During transportation, the mixing drum will always keep rotating to ensure that the concrete will not solidify. After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from occupying space.
