要知道在挖掘机施工作业中,水温和油温过高是很常见的现象，而其对机器性能的伤害却是很大。那到底是什么原因导致这种情况出现呢？下面加长臂挖掘机出租厂家为您分析。

It should be known that high water temperature and oil temperature are common phenomena in excavator construction, but they do great harm to machine performance. What is the reason for this? The following extended boom excavator rental manufacturer will analyze for you.

为什么会水温高？

Why is the water temperature high?

水箱是用来散热的，而这个散热方式是风冷，也就是发动机带动的风扇。所以说，水温高的原因有：

The water tank is used for heat dissipation, which is air cooling, that is, the fan driven by the engine. Therefore, the reasons for high water temperature are:

节温器卡死，打不开了，这时水只能走小循环，不通过散热器了。

The thermostat is stuck and cannot be opened. At this time, the water can only circulate in a small way, instead of passing through the radiator.

水箱里面脏了，水不流畅，这可以用测温枪检测水箱上下的温度，堵了下面温度会很低。

The inside of the water tank is dirty and the water is not smooth. You can use a temperature measuring gun to measure the temperature above and below the water tank. If it is blocked, the temperature will be very low.

风扇转速不够，离合器故障。

Insufficient fan speed, clutch failure.

散热器周边的胶条坏损或没有，这时回产生涡流，热风被循环，不能达到冷却效果。

The rubber strip around the radiator is damaged or not. At this time, eddy current will be generated and hot air will be circulated, so the cooling effect cannot be achieved.

大家容易忽略的一点，就是会不会误报警，传感器坏了，这也有可能的，电脑是很木的，只看数据不看实情。

It is easy to overlook that whether there will be false alarm or sensor failure, which is also possible. The computer is very wooden, just looking at the data rather than the actual situation.

为什么会油温高？

Why is the oil temperature high?

油温高和水温高相似，也有大小循环，只是不是通过节温器，他有个回油单向阀，如果这个阀卡了，油温会高，其他的和水温一样。

The high oil temperature is similar to the high water temperature. There are large and small cycles, but not through the thermostat. It has an oil return check valve. If this valve is stuck, the oil temperature will be high. Other things are the same as the water temperature.

当然，大挖机是靠风扇泵驱动风扇马达调整转速，还有一个溢流装置，一般油温高，检查这几个地方都可以解决。

Of course, the speed of the excavator is adjusted by the fan motor driven by the fan pump, and there is also an overflow device. Generally, the oil temperature is high, which can be solved through inspection.

正常温度在80摄氏度到90摄氏度之间，如果高出这个温度，造成开锅，那么就要对照以上可能原因逐次以排除法检查。你有需求可以来我们这里http://www.dybocheng.com租赁挖机进行施工！

The normal temperature is between 80 ℃ and 90 ℃. If the temperature is higher than this and the cooking starts, the above possible causes should be checked one by one with the elimination method. You can come here if you need http://www.dybocheng.com Rental excavator for construction!
