搅拌机发动机工作温度过低的故障如何诊断

在自动搅拌一体机行驶中，若冷却液温度表长时是指示在发动机正常工作温度以下，即可判定为发动机工作温度过低。

If the coolant temperature indicator is below the normal operating temperature of the engine for a long time, it can be judged that the engine operating temperature is too low.

对一定的发动机而言，不可能因发生故障而导致冷却强度加大或传热损失减少，从而使发动机工作温度过低，发动机工作温度过低，通常是自然因素或冷却系统的冷却强度调节装置失效所致，为此，发动机出现工作温度过低的现像时，应进行以下检查。

For a certain engine, it is impossible to increase the cooling intensity or reduce the heat transfer loss due to the failure of the engine, so that the working temperature of the engine is too low, which is usually caused by natural factors or the failure of the cooling intensity regulating device of the cooling system. For this reason, when the working temperature of the engine is too low, the following inspection should be carried out.

1，环璄温度较低时，检查百叶窗是否关闭，是否采取了有效的保温措施。

1. When the ambient temperature is low, check whether the shutter is closed and whether effective insulation measures are taken.

2，检查风扇控制装置是否失效，如果冷却系统装有风扇离合器或装用电动风扇，可在发动机工作温度较低时，通过观察风扇的运转状态来确定风扇控制装置是不否失效。

2. Check whether the fan control device fails. If the cooling system is equipped with a fan clutch or an electric fan, the fan control device can be determined whether the fan control device is invalid by observing the running state of the fan when the engine operating temperature is low.

3，检查节温器是否正常，在发动机工作温度较低时，通过触试散热器温度来判断冷却液是否进行大循环，以诊断节温器是否正常。

3. Check whether the thermostat is normal. When the engine working temperature is low, judge whether the coolant is circulating by touching the radiator temperature to diagnose whether the thermostat is normal.

4，如果冷却液温度表指示温度低，但发动机工作中无其他异常现象，应对冷却液温茺和冷却液温度传感器进行检查。

4. If the coolant temperature gauge indicates low temperature, but there is no other abnormal phenomenon during engine operation, check the coolant temperature and coolant temperature sensor.
