1. 發動機高溫,但是冷卻液沒有減少
1. The engine is hot, but the coolant is not reduced
大型混凝土攪拌機過熱,但是冷卻系統工作正常,這時應保持發動機怠速運轉,嚴禁熄火,用冷水澆散熱器表面加速降溫,在溫度下降到50度左右的時候,用濕毛巾旋開水箱蓋,進行降溫,然后一定要檢查油尺刻度是否在正常范圍內。
The large concrete mixer is overheated, but the cooling system works normally. At this time, the engine should be kept idling. It is strictly forbidden to turn off the engine. Pour cold water on the surface of the radiator to speed up the cooling. When the temperature drops to about 50 degrees, loosen the water tank cover with a wet towel to cool down. Then be sure to check whether the oil dipstick scale is within the normal range.
2. 發動機水溫過高,冷卻系統循環出現故障
2. The engine water temperature is too high, and the cooling system circulation fails
大型混凝土攪拌機,發動機水溫過高,冷卻系統循環出現故障的原因有很多,比如節溫器,冷卻硅油風扇,風扇皮帶等損壞導致冷卻系統無法正常工作。首先要保持發動機怠速狀態,用冷水給散熱器降溫,在發動機溫度降到80度以下時,采取間斷熄火,踩下熄火開關或者拔掉電噴系統傳感器,用起動機帶動發動機運轉,10-15秒為一個運轉周期,本棟運轉降溫,檢查機油尺刻度是否在正常范圍內。
For large concrete mixer, the engine water temperature is too high, and there are many reasons for the failure of the cooling system cycle, such as thermostat, cooling silicone oil fan, fan belt and other damage, resulting in the cooling system can not work normally. First of all, keep the engine idling and cool the radiator with cold water. When the engine temperature drops below 80 ℃, stop the engine intermittently, step on the flameout switch or unplug the sensor of the EFI system, and use the starter to drive the engine to run. 10-15 seconds is an operation cycle to cool the building. Finally, check whether the oil dipstick scale is within the normal range.

3. 冷卻液發生遺漏或者散失,發動機冷卻系統處于干燒狀態
3. The coolant is missing or lost, and the engine cooling system is in dry burning state
大型混凝土攪拌機發動機在沒有冷卻液狀態下運轉,尤其是在夏天,是會造成嚴重事故的,這時采用任何冷卻水澆散熱器的方式降溫都是無效的,發動機運轉也無法散熱。此時在發動機怠速狀態下,打開機油加注口,迅速加注潤滑油,這主要是因為在徹底缺水狀態下,發動機潤滑油會隨之大量高溫蒸發,必須迅速補充。
Large concrete mixer engine running without coolant, especially in summer, will cause serious accidents. At this time, it is invalid to use any way of cooling water pouring radiator to cool down, and the engine running can not dissipate heat. At this time, in the idle state of the engine, open the oil filler and quickly fill the lubricating oil. This is mainly because in the state of complete water shortage, the engine lubricating oil will evaporate with a large amount of high temperature and must be quickly replenished.
加完潤滑油后必須熄火,采取任意辦法讓發動機熄火斷油,同時運轉啟動機,被動運轉發動機,可持續10秒運轉,間隔5秒停頓,保持此頻率。寧可損壞一個啟動機,也要保住發動機,zui大程度避免粘缸、拉缸等嚴重事故。混凝土攪拌車價格適中,利潤可觀,值得考慮,但是對大型混凝土攪拌機的常見故障的解決辦法也要了解,這樣在出現問題時才能冷靜處理。
After adding lubricating oil, the engine must be shut down. Take any method to shut down the engine and cut off the oil. At the same time, run the starter and run the engine passively. It can last for 10 seconds and stop at an interval of 5 seconds to maintain this frequency. It is better to damage a starter than to keep the engine. To a large extent, serious accidents such as cylinder sticking and cylinder pulling should be avoided. The price of concrete mixer is moderate and the profit is considerable, which is worth considering. However, the solutions to the common faults of large concrete mixer should also be understood, so as to deal with the problems calmly.
