如何保养混凝土自上料搅拌车的燃油系统？
我们都知道，混凝土自上料搅拌车的发动机能够正常运转，机械稳定的作业，这些都离不开燃油系统为其提供动力。我们在使用混凝土搅拌车的时候也会遇到发动机无法启动或启动无力的现象，这一般都是因为混凝土搅拌车的燃油系统出现了故障，所以，我们在平时使用的时候就要做好燃油系统的日常保养，具体内容请看下文。
As we all know, the engine of concrete self loading mixer can operate normally and operate mechanically stably, which cannot be separated from the power provided by the fuel system. When we use the concrete mixer, we will also encounter the phenomenon that the engine can not start or the start is weak. This is generally due to the failure of the fuel system of the concrete mixer. Therefore, we need to do a good job in the daily maintenance of the fuel system when we use it. Please see the following for the specific content.
1、及时加注燃油
1. Fill the fuel in time
混凝土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，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 concrete mixer operation, the operator should pay attention to the fuel quantity at any time. When the fuel quantity shown on the fuel meter is close to the "0" position, the fuel should be filled in time. Do not add fuel until it is exhausted. This will not only cause the diesel engine to stop when there is no fuel, but also cause air to enter the fuel system. Once air enters the fuel system, it will not only waste fuel, but also cause trouble in discharging.
2、注意避免燃油系统堵塞
2. Pay attention to avoid fuel system blockage
我们都知道，有时候混凝土搅拌车的工作环境比较特殊，这样就很容易导致混凝土搅拌车燃油系统堵塞，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。
As we all know, sometimes the working environment of the concrete mixer is special, which can easily lead to the blockage of the fuel system of the concrete mixer. Once the fuel system is blocked, it will affect the normal operation of the machine, so it is necessary to check in time to ensure the smoothness of the fuel pipe.
3、注意检查燃油系统密封性
3. Pay attention to check the tightness of the fuel system
混凝土搅拌车作业的时候，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。
When the concrete mixer truck is working, 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
混凝土搅拌车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 of the fuel system of the concrete mixer truck are caused by the unclean fuel. For the gasoline engine, most of them are caused by the water in the fuel. The water in the gasoline will also corrode and damage the components of the fuel supply system.
5、燃油选择很关键
5. Fuel selection is key
建议选择适合混凝土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 concrete mixer should be selected. The poor quality fuel has poor filtration, sludge, impurities, moisture, long-term accumulation and precipitation, which is easy to block the filter screen, oil pipe and nozzle of oil pump.
混凝土搅拌车是用来运送建筑用混凝土的专用卡车；由于它的外形，也常被称为田螺车，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，以保障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。
Concrete mixer truck is a special truck used to transport construction concrete; Because of its shape, it is often called Tianluo truck. This kind of truck is equipped with cylindrical mixing drum to carry the mixed concrete. During transportation, the mixing drum will always rotate 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.
