所謂工況突變，是指攪拌車(chē)工況突然出現異?，F象，這是一種常見(jiàn)的故障癥狀。下面就來(lái)講講相關(guān)內容吧。

The so-called sudden change of working condition refers to the sudden abnormal phenomenon of mixing truck working condition, which is a common fault symptom. Now let's talk about the relevant content.

例如：攪拌車(chē)突然停車(chē)后難以啟動(dòng)，甚無(wú)法啟動(dòng)；行駛中攪拌車(chē)功率突然下降，行駛無(wú)力；行駛中剎車(chē)失靈或突然跑偏，甚失靈。這種故障癥狀明顯，易于檢測。

For example, it is difficult to start or even fail to start after the mixer stops suddenly; The power of the mixer truck suddenly drops during driving, and the driving is weak; When driving, the brake fails or suddenly deviates, or even fails. This kind of fault symptom is obvious and easy to detect.

異響。攪拌車(chē)在行駛過(guò)程中的異響是攪拌車(chē)故障的“報警”。司機應該意識到攪拌車(chē)出了問(wèn)題。他應立即停止攪拌車(chē)進(jìn)行檢查。他決不能讓攪拌車(chē)“與疾病一起工作”。

Abnormal noise. The abnormal sound of the mixer truck during driving is the "alarm" of the mixer truck fault. The driver should be aware that there is something wrong with the mixer. He should immediately stop the mixer truck for inspection. He must not let the mixer "work with disease".

排煙顏色異常。在攪拌車(chē)工作過(guò)程中，正常燃燒產(chǎn)物的主要成分應為二氧化碳和少量水蒸氣。如果攪拌車(chē)燃燒不正常，廢氣中會(huì )混入不完全燃燒的碳顆粒、碳氫化合物、一氧化碳和大量水蒸氣。

The smoke exhaust color is abnormal. During the operation of the mixer truck, the main components of normal combustion products should be carbon dioxide and a small amount of water vapor. If the mixing car burns abnormally, the exhaust gas will be mixed with incompletely burned carbon particles, hydrocarbons, carbon monoxide and a large amount of water vapor.

此外，還有氮氧化物等。此時(shí)，廢氣的顏色可能會(huì )變成黑色、藍色或白色，這意味著(zhù)排氣煙顏色異常。對于汽油機，正常排氣時(shí)應無(wú)明顯煙霧。

In addition, there are nitrogen oxides. At this time, the color of exhaust gas may turn black, blue or white, which means that the color of exhaust smoke is abnormal. For gasoline engines, there should be no obvious smoke during normal exhaust.

但當潤滑油向氣缸上移時(shí)，尾氣呈藍色；當燃燒不完全時(shí)，尾氣呈黑色；當油與水混合時(shí)，尾氣呈白色。

However, when the lubricating oil moves upward to the cylinder, the tail gas is blue; When the combustion is incomplete, the tail gas is black; When oil and water are mixed, the tail gas is white.

在混凝土攪拌車(chē)的變速器、驅動(dòng)橋、主減速器、差速器和制動(dòng)器總成中經(jīng)常出現“過(guò)熱和高溫”。如攪拌車(chē)發(fā)動(dòng)機過(guò)熱時(shí)，主要是冷卻系統問(wèn)題，冷卻液不足或泵不工作；變速器、驅動(dòng)橋過(guò)熱時(shí)，主要是潤滑油不足；

"Overheating and high temperature" often appear in the transmission, drive axle, main reducer, differential and brake assembly of concrete mixer truck. For example, when the engine of the mixer truck is overheated, it is mainly the problem of the cooling system, insufficient coolant or the pump does not work; When the transmission and drive axle are overheated, the main reason is insufficient lubricating oil;

制動(dòng)器過(guò)熱時(shí)，主要是制動(dòng)蹄片不工作返回。有時(shí)，上述現象會(huì )被儀表板上的警示燈直接反映出來(lái)，這就需要駕駛員在行駛時(shí)注意觀(guān)察，外部溫度也可以用手測量。

When the brake overheats, it is mainly because the brake shoe does not work and returns. Sometimes, the above phenomena will be directly reflected by the warning light on the instrument panel, which requires the driver to observe carefully when driving, and the external temperature can also be measured by hand.

泄漏是指發(fā)動(dòng)機燃油、潤滑油（或齒輪油）、制動(dòng)液（或壓縮空氣）、動(dòng)力轉向系統油的泄漏。這也是一個(gè)明顯的故障癥狀，仔細觀(guān)察可以發(fā)現。

Leakage refers to the leakage of engine fuel, lubricating oil (or gear oil), brake fluid (or compressed air) and power steering system oil. This is also an obvious fault symptom, which can be found by careful observation.

例如，當壓縮空氣泄漏時(shí)，可以清楚地聽(tīng)到空氣泄漏的聲音。燃料、潤滑油消耗過(guò)大，說(shuō)明攪拌車(chē)技術(shù)狀況惡化，出現故障。

For example, when compressed air leaks, the sound of air leakage can be clearly heard. Excessive consumption of fuel and lubricating oil indicates that the technical condition of the mixer truck has deteriorated and malfunctioned.

面對攪拌車(chē)工況突變要提前診斷處理是正確的行為，您要好好了解這方面的操作，更多內容就來(lái)網(wǎng)站http://www.v811.cn咨詢(xún)吧。
