混凝土自上料搅拌车工作状况突变怎么回事？
所谓工作状况突变，系指混凝土自上料搅拌车的工作状况突然出现不正常现象，这是比较常见的故障症状。例如：搅拌车发动机突然熄火后再启动困难，甚不能启动；搅拌车发动机在行驶中动力突然降低，行驶无力；行驶中突然制动失灵或跑偏，甚失效等。这种故障的症状明显，故容易察觉。混凝土自上料搅拌车厂家为您讲解。
The so-called sudden change of working condition means that the working condition of the concrete self loading mixer suddenly appears abnormal, which is a common fault symptom. For example, it is difficult or even impossible to start the mixer truck after the engine suddenly stops; The power of the agitator truck engine suddenly decreases during driving, and the driving is weak; Sudden brake failure, deviation or even failure during driving. The symptom of this fault is obvious, so it is easy to detect.
过热高温
Overheating high temperature
通常出现在混凝土自上料搅拌车发动机、变速器、驱动桥主减速器、差速器及制动器等总成上。例如，搅拌车发动机过热，多为冷却系有问题，是缺冷却液或泵不工作；变速器和驱动桥过热，多为缺润滑油所致；制动器过热，多为制动蹄片不回位而引起。以上现象有时可以通过仪表板警示灯直接反映出来，需要驾驶人驾车时注意观察，也可以用手测试外表温度。
It usually appears on the engine, transmission, drive axle main reducer, differential and brake assemblies of concrete self loading mixer truck. For example, the engine of the mixer truck is overheated, most of which are due to problems in the cooling system, lack of coolant or pump failure; Overheating of transmission and drive axle is mostly caused by lack of lubricating oil; Brake overheating is mostly caused by brake shoe not returning. The above phenomena can sometimes be directly reflected by the warning light on the instrument panel. The driver should pay attention to the observation when driving, and can also test the surface temperature by hand.
排气烟色不正常：
Abnormal exhaust smoke color:
混凝土自上料搅拌车发动机在工作过程中，正常的燃烧生成物主要成分应当是二氧化碳和少量的水蒸汽。如果搅拌车发动机燃烧不正常，废气中会掺有未完全燃烧的炭微粒、碳氢化合物、一氧化碳和大量的水蒸汽。
During the operation of the engine of the concrete self loading mixer, the main components of the normal combustion products should be carbon dioxide and a small amount of water vapor. If the engine of the mixer truck does not burn normally, the exhaust gas will be mixed with incomplete burning carbon particles, hydrocarbons, carbon monoxide and a large amount of water vapor.
此外，还有氮氧化合物等，这时尾气的颜色可能变黑、变蓝或变白，也就是说排气烟色不正常。对于汽油机，正常尾气应无明显的烟雾。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 addition, there are nitrogen oxides, etc. At this time, the color of the tail gas may turn black, blue or white, which means that the exhaust smoke color is abnormal. For gasoline engines, there should be no obvious smoke in the normal exhaust. However, when the lubricating oil moves up 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.
一旦混凝土自上料搅拌车在使用中突发故障，建议大家定要及时停止工作，这样才能针对性进行检查，避免出现更严重的故障问题。当然，要想更好的降低搅拌车的故障率，还需大家在平时使用时通过正确的方法应用，并加强对搅拌车的定期维护和保养。关注我们https://www.jfjiaobanche.com，了解更多事项！
Once the concrete self loading mixer breaks down suddenly in use, it is suggested that everyone should stop working in time, so as to carry out targeted inspection and avoid more serious problems. Of course, in order to better reduce the failure rate of the mixer, it is also necessary for everyone to apply the correct method when using the mixer at ordinary times, and strengthen the regular maintenance and repair of the mixer.
