1. 发动机高温,但是冷却液没有减少
1. The engine is hot, but the coolant is not reduced
大型混凝土搅拌机过热,但是冷却系统工作正常,这时应保持发动机怠速运转,严禁熄火,用冷水浇散热器表面加速降温,在温度下降到50度左右的时候,用湿毛巾旋开水箱盖,进行降温,然后一定要检查油尺刻度是否在正常范围内。
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. 发动机水温过高,冷却系统循环出现故障
2. The engine water temperature is too high, and the cooling system circulation fails
大型混凝土搅拌机,发动机水温过高,冷却系统循环出现故障的原因有很多,比如节温器,冷却硅油风扇,风扇皮带等损坏导致冷却系统无法正常工作。要保持发动机怠速状态,用冷水给散热器降温,在发动机温度降到80度以下时,采取间断熄火,踩下熄火开关或者拔掉电喷系统传感器,用起动机带动发动机运转,10-15秒为一个运转周期,本栋运转降温,检查机油尺刻度是否在正常范围内。
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. 冷却液发生遗漏或者散失,发动机冷却系统处于干烧状态
3. The coolant is missing or lost, and the engine cooling system is in dry burning state
大型混凝土搅拌机发动机在没有冷却液状态下运转,尤其是在夏天,是会造成严重事故的,这时采用任何冷却水浇散热器的方式降温都是无效的,发动机运转也无法散热。此时在发动机怠速状态下,打开机油加注口,迅速加注润滑油,这主要是因为在彻底缺水状态下,发动机润滑油会随之大量高温蒸发,必须迅速补充。
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.
加完润滑油后必须熄火,采取任意办法让发动机熄火断油,同时运转启动机,被动运转发动机,可持续10秒运转,间隔5秒停顿,保持此频率。宁可损坏一个启动机,也要保住发动机,zui大程度避免粘缸、拉缸等严重事故。混凝土搅拌车适中,利润可观,值得考虑,但是对大型混凝土搅拌机的常见故障的办法也要了解,这样在出现问题时才能冷静处理。
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.
