混凝土自上料攪拌車工作狀況突變怎么回事？
所謂工作狀況突變，系指混凝土自上料攪拌車的工作狀況突然出現(xiàn)不正?，F(xiàn)象，這是比較常見的故障癥狀。例如：攪拌車發(fā)動機突然熄火后再啟動困難，甚不能啟動；攪拌車發(fā)動機在行駛中動力突然降低，行駛無力；行駛中突然制動失靈或跑偏，甚失效等。這種故障的癥狀明顯，故容易察覺。混凝土自上料攪拌車廠家為您講解。
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.
過熱高溫
Overheating high temperature
通常出現(xiàn)在混凝土自上料攪拌車發(fā)動機、變速器、驅動橋主減速器、差速器及制動器等總成上。例如，攪拌車發(fā)動機過熱，多為冷卻系有問題，是缺冷卻液或泵不工作；變速器和驅動橋過熱，多為缺潤滑油所致；制動器過熱，多為制動蹄片不回位而引起。以上現(xiàn)象有時可以通過儀表板警示燈直接反映出來，需要駕駛人駕車時注意觀察，也可以用手測試外表溫度。
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.
排氣煙色不正常：
Abnormal exhaust smoke color:
混凝土自上料攪拌車發(fā)動機在工作過程中，正常的燃燒生成物主要成分應當是二氧化碳和少量的水蒸汽。如果攪拌車發(fā)動機燃燒不正常，廢氣中會摻有未完全燃燒的炭微粒、碳氫化合物、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，還有氮氧化合物等，這時尾氣的顏色可能變黑、變藍或變白，也就是說排氣煙色不正常。對于汽油機，正常尾氣應無明顯的煙霧。但潤滑油上竄氣缸時，尾氣呈藍色；燃燒不完全時，尾氣呈黑色，油中摻水時，尾氣呈白色。
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.
一旦混凝土自上料攪拌車在使用中突發(fā)故障，建議大家定要及時停止工作，這樣才能針對性進行檢查，避免出現(xiàn)更嚴重的故障問題。當然，要想更好的降低攪拌車的故障率，還需大家在平時使用時通過正確的方法應用，并加強對攪拌車的定期維護和保養(yǎng)。關注我們http://www.zvmc.cn，了解更多事項！
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.
