Automatic feeding mixer has a good market value, now the scope of use is more and more widely, of course, the use of a long time can not avoid all kinds of failure problems, but some failures are caused by symptoms before appearing. Let's take a look.

　　异响。如果自动上料搅拌机行驶过程中出现异响，应立即下车检查，或到维修点排除故障，切不可让搅拌车“带病工作”。万一在路上发生事故，对施工和本身都会造成不小的影响。

　　Sound. If there is abnormal sound in the driving process of the automatic feeding mixer, it should be checked immediately, or go to the professional maintenance point to troubleshoot, and must not let the mixer "work with illness". In case of accidents on the road, the construction and itself will cause no small impact.

　　工作状态异常。工况是指搅拌车在行驶或搅拌混凝土时出现的异常现象。这些现象包括发动机突然熄火后难以启动或无法启动；运转中发动机功率突然降低，或刹车失灵或跑偏等。此类故障比较明显，更容易发现。

　　The working status is abnormal. Working condition refers to the abnormal phenomenon that appears when the mixer is driving or mixing concrete. These phenomena include the difficulty or inability to start the engine after sudden flameout; Operation of the engine power suddenly reduced, or brake failure or deviation. This type of fault is obvious and easy to detect.

　　漏液。泄漏的液体主要包括发动机燃油、制动液（压缩空气）和动力转向液的泄漏。仔细观察这个故障也可以发现。当漏气时，可以听到明显的漏气声。

　　Leakage. The leaking fluids mainly include engine fuel, brake fluid (compressed air) and power steering fluid leakage. This failure can also be found by careful observation. When air leaks, a distinct sound of air leakage can be heard.

　　高温过热。高温过热主要发生在搅拌车发动机、变速器、制动器等设备上。如果发动机过热，多为冷却系统有问题，冷却液不足或泵不工作；如果变速箱和驱动桥过热，很可能是缺少润滑油；如果刹车过热，多半是刹车片不回位。以上现象无需过多分心，直接反映在仪表盘上的警示灯上即可，只要驾驶员在驾驶时注意即可。

　　Overheating. High temperature overheating mainly occurs in the engine, transmission, brakes and other equipment of the agitator car. If the engine overheats, there are problems with the cooling system, insufficient coolant or pump does not work; If the gearbox and drive axle overheat, there is likely to be a lack of lubricating oil; If the brakes overheat, most likely the brake pads do not return. The above phenomenon does not need too much distraction, directly reflected in the dashboard warning light, as long as the driver pays attention to driving.

　　排气颜色异常。正常情况下，搅拌车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，属于异常排气。但是，当润滑油向上跑气缸时，排气是蓝色的；燃烧不完全时，废气为黑色，油与水混合时，废气为白色。

　　The exhaust color is abnormal. Normally, the fumes from the engine of the mixer are carbon dioxide and water vapor. If the exhaust gas contains hydrocarbons, carbon monoxide and carbon particles, it will turn blue, black or white, which is abnormal exhaust. However, when the lubricating oil runs up the cylinder, the exhaust is blue; When the combustion is incomplete, the exhaust gas is black, and when oil and water are mixed, the exhaust gas is white.

　　如果忽略掉以上所讲解的征兆，那么将对搅拌机的行驶和工作造成很大的影响，操作人员要多加注意。当然作为一种工程车，自动上料搅拌机也需要保养，这样才能让设备使用时间变得更长。更多内容来网站http://www.zkhntjbj.com了解吧！

　　If the above mentioned symptoms are ignored, it will have a great impact on the running and working of the mixer, so the operator should pay more attention to it. Of course, as a kind of engineering vehicle, the automatic feeding mixer also needs maintenance, so as to make the equipment longer. Come to http://www.zkhntjbj.com for more information!
