自動攪拌車在使用過一段時間之后，就會有各種各樣問題出現(xiàn)，需要及時進(jìn)行處理解決，下面來看三個方面的問題吧。

After using the automatic mixer for a period of time, there will be various problems that need to be solved in time. Let's look at three aspects.

一：攪拌車高速行駛時1000攪拌站，時速達(dá)到每小時150公里，但不及時增加檔位，速度已超過四千轉(zhuǎn)。這是什么原因

1： When the mixer truck runs at high speed, the speed of 1000 mixing stations reaches 150 kilometers per hour, but the gear is not increased in time, and the speed has exceeded 4000 revolutions. Why

原因：當(dāng)機油壓力電磁閥發(fā)生故障時，攪拌車的變速箱將進(jìn)入傾斜模式，并迫使第三檔驅(qū)動。此故障是壓力調(diào)節(jié)故障。您需要去商店辦理入住手續(xù)。嘗試更換變速箱油。換油后，將其鎖定在第三檔，然后需要更換電磁閥。

Cause: When the oil pressure solenoid valve fails, the gearbox of the mixer will enter the tilting mode and force the third gear drive. This fault is a pressure regulation fault. You need to check in at the store. Try changing the transmission oil. After changing the oil, lock it in the third gear, and then replace the solenoid valve.

二：攪拌車打開一段時間后，水溫報警燈會自動熄滅，這是什么原因？

2： After the mixer is turned on for a period of time, the water temperature alarm light will go out automatically. What is the reason?

原因：如果發(fā)生這種情況，首先建議檢查防凍劑是否已耗盡。如果水箱中缺少防凍劑，應(yīng)立即將其添加到正常水平。其次，攪拌車會自然損失防凍劑，但不會損失太多。如果發(fā)現(xiàn)需要在短時間內(nèi)頻繁添加，則需要檢查水箱，水管，加注瓶和小型加熱水箱，以檢查這些零件是否漏水。

Cause: If this happens, it is recommended to check whether the antifreeze has been used up. If antifreeze is lacking in the water tank, it should be added to the normal level immediately. Secondly, the mixer will naturally lose antifreeze, but not too much. If it is found that it needs to be added frequently in a short time, check the water tank, water pipe, filling bottle and small heating water tank to check whether these parts are leaking.

三：開車時，總是覺得攪拌車制冷不充分。這是要添加的制冷劑嗎?

3： When driving, I always feel that the refrigeration of the mixer is insufficient. Is this the refrigerant to be added?

原因：攪拌車中缺少制冷劑的原因主要是由于系統(tǒng)中少量的制冷劑泄漏。如果攪拌車空調(diào)系統(tǒng)中的制冷劑不足，從膨脹閥注入蒸發(fā)器的制冷劑將不可避免地減少。當(dāng)攪拌車中的制冷劑在蒸發(fā)器中蒸發(fā)時，吸收的熱量也會減少，冷卻能力也會降低減少。建議先去服務(wù)站或維修店檢查。如果檢查結(jié)果表明不需要添加，則無需添加，因為混合器中的制冷劑過多是不好的。

Cause: The lack of refrigerant in the mixer truck is mainly due to the leakage of a small amount of refrigerant in the system. If the refrigerant in the air conditioning system of the truck mixer is insufficient, the amount of refrigerant injected into the evaporator from the expansion valve will inevitably decrease. When the refrigerant in the truck mixer evaporates in the evaporator, the heat absorbed will also be reduced, and the cooling capacity will also be reduced. It is recommended to go to the service station or repair shop for inspection first. If the inspection results show that it is not necessary to add, it is unnecessary to add, because it is bad to have too much refrigerant in the mixer.
