众所周知，小型混凝土搅拌机发动机能够正常运转，机器能够进行作业，主要是依靠燃油系统提供动力。很多时候，机器发动机无法启动或启动无力，都是因为燃油系统出现了故障，所以，要做好燃油系统的日常保养。
As we all know, the small concrete mixer engine can run normally, the machine can work efficiently, mainly relying on the fuel system to provide power. Most of the time, the machine engine can not start or start powerless, all because of the fuel system failure, so, to do a good job in the fuel system routine maintenance.
1、及时加注燃油
1. Add fuel in time
小型混凝土搅拌机作业的过程中，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。
In the process of small concrete mixer operation, the operator should pay attention to the amount of fuel at any time. When the fuel quantity shown on the fuel gauge is close to the "0" position, it is necessary to add fuel in time. Do not wait until the fuel is exhausted before adding. This will not only cause the diesel engine flameout after no fuel, but also cause air to enter the fuel system. Once air enters the fuel system, it not only wastes fuel, but also is troublesome to discharge.
2、注意避免燃油系统堵塞
2. Pay attention to avoid fuel system blockage
我们都知道，有时候混凝土搅拌机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 concrete mixer is special, which can easily lead to fuel system blockage. Once the fuel system is blocked, it will affect the normal operation of the machine. 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
小型混凝土搅拌机作业的时候，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 concrete 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 dirty fuel. For gasoline engines, most of them are caused by water mixed in the fuel, which will corrode and destroy the fuel supply system components.
5.燃油选择很关键
5. Fuel selection is critical
建议选择适合混凝土搅拌机的高品质燃油，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 to select high-quality fuel oil suitable for concrete mixer. The poor quality fuel oil has poor filtration, sludge, impurities and moisture, which will accumulate and precipitate for a long time, which will easily block the oil pump filter screen, oil pipe and nozzle.
小型混凝土搅拌机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。
Small concrete mixers, such as trucks, are equipped with cylindrical mixing cylinders to carry the mixed concrete. In the process of transportation, the mixing drum will always rotate to ensure that the concrete transported will not set. After delivery of concrete, the inside of the mixing drum is usually washed with water to prevent hardened concrete from occupying space.
