混凝土搅拌机出现以下五种情况，就需要保养了！

Concrete mixer in the following five cases, it needs maintenance!

1.异常噪音

1. Abnormal noise

如果混凝土搅拌机在行驶过程中发出奇怪的噪音，应立即下车检查，或前往维修点进行故障排除。千万不要让搅拌机“带病工作”。万一路上发生事故，对施工和自身都有很大影响。

If the concrete mixer makes strange noise during driving, you should get off the car immediately for inspection or go to the professional maintenance point for troubleshooting. Don't let blenders work with diseases. In case of an accident on the road, it has a great impact on the construction and itself.

2.高温过热

2. High temperature and overheating

高温过热主要发生在搅拌机的发动机、变速器、制动器等设备上。如果发动机过热，大多是冷却系统有问题，冷却液不足或者泵不工作；如果变速器和驱动桥过热，很可能是润滑油不足；制动器过热大多是由于制动蹄无法返回造成的。这些现象可以直接反映在仪表盘的警示灯上，而不会分散太多的注意力，只要司机开车时注意观察就可以了。

High temperature overheating mainly occurs in the mixer engine, transmission, brake and other equipment. If the engine overheats, most of the problems are the cooling system, insufficient coolant or the pump does not work; If the transmission and drive axle overheat, it is likely that the lubricating oil is insufficient; Brake overheating is mostly caused by the brake shoes can not return. These phenomena can be directly reflected in the warning light of the instrument panel, and will not distract too much attention, as long as the driver pays attention to observe when driving.

3.工作不正常

3. Abnormal work

工作状况指的是搅拌机在行驶或搅拌混凝土时出现不正常现象。这些现象包括发动机突然熄火后很难启动或不能启动；发动机在工作中动力突然降低，或者制动失灵或跑偏等。这类故障比较明显，比较容易察觉。

Working condition refers to the abnormal phenomenon when the mixer is running or mixing concrete. These phenomena include that it is difficult to start or unable to start the engine after sudden flameout; When the engine is working, the power suddenly decreases, or the brake fails or deviates. This kind of fault is obvious and easy to detect.
                    

4.液体泄漏

4. Liquid leakage

泄漏的液体主要包括发动机燃油、制动液(压缩空气)、动力转向液等泄漏现象。这种毛病，仔细观察就能发现。漏气时，可以听到明显的漏气声。

The leaking liquid mainly includes engine fuel, brake fluid (compressed air) and power steering fluid. This kind of defect can be found by careful observation. In case of air leakage, obvious air leakage can be heard.

5.搅拌机排气颜色异常

5. The exhaust color of mixer is abnormal

一般情况下，搅拌机发动机排放的烟雾是二氧化碳和水蒸气。如果废气中含有碳氢化合物、一氧化碳和碳颗粒，废气会变成蓝色、黑色或白色，这意味着废气异常。。但润滑油上窜气缸时，尾气呈蓝色；燃烧不完全时，尾气呈黑色，油中掺水时，尾气呈白色。

In general, the smoke emitted by the mixer engine is carbon dioxide and water vapor. If the exhaust contains hydrocarbons, carbon monoxide and carbon particles, the exhaust will turn blue, black or white, which means that the exhaust is abnormal.. But when the lubricating oil goes up to the cylinder, the exhaust gas is blue; When the combustion is incomplete, the tail gas is black, and when the oil is mixed with water, the tail gas is white.

以上症状说明混凝土搅拌机处于故障状态。需要及时检查维护。如果不重视，搅拌机的行驶和工作都会受到很大影响。

The above symptoms indicate that the concrete mixer is in fault state. Timely inspection and maintenance are required. If we don't pay attention to it, the driving and working of the mixer will be greatly affected.
