发电机组产生高温原因如下：

The reasons for the high temperature generated by the generator set are as follows:

1、长时间超负荷作业

1. Long term overloaded work

柴油机长时间超负荷作业，会使其油耗增加、热负荷升高，从而出现水温过高现象。为此，应避免长时间超负荷作业。

Long term overloaded operation of diesel engines can increase fuel consumption and heat load, resulting in high water temperature. For this reason, long-term overload operations should be avoided.

2、冷却液不足

2. Insufficient coolant

柴油机冷却系统中若缺少冷却液，则会影响柴油机散热效果，造成柴油机高温。对此，应经常检查散热器及膨胀水箱内冷却液存量，液位低时应及时补充。

If there is a lack of coolant in the cooling system of a diesel engine, it will affect the heat dissipation effect of the diesel engine and cause high temperatures. For this, it is necessary to regularly check the coolant level in the radiator and expansion tank, and replenish it in a timely manner when the liquid level is low.

3、冷却液循环不畅

3. Poor circulation of coolant

节温器开度不足，会降低柴油机冷却系统大循环的散热能力。如果柴油机高温，可以将节温器放入水中进行加热检查，一般节温器的开启距离为8～10mm。

Insufficient opening of the thermostat will reduce the heat dissipation capacity of the large circulation of the diesel engine cooling system. If the diesel engine is hot, the thermostat can be placed in water for heating inspection. Generally, the opening distance of the thermostat is 8-10mm.

提醒： 水泵性能不良，则会造成冷却液流量降低，致使柴油机高温。

Reminder: Poor performance of the water pump can cause a decrease in coolant flow, resulting in high temperatures in the diesel engine.

4、散热装置相互干涉

4. Interference between heat dissipation devices

如果液压油散热器与水散热器一前一后放置，当液压油温度偏高时，势必会造成水散热器进风侧冷风温度偏高，影响水散热器散热。对此，应检修液压系统散热情况，降低液压油散热器对柴油机水散热器散热不良的影响。

If the hydraulic oil radiator and the water radiator are placed in front of each other, when the temperature of the hydraulic oil is too high, it will inevitably cause the cold air temperature on the inlet side of the water radiator to be too high, affecting the heat dissipation of the water radiator. Regarding this, it is necessary to inspect the heat dissipation of the hydraulic system and reduce the impact of the hydraulic oil radiator on the poor heat dissipation of the diesel engine water radiator.

5、散热器表面附着杂物

5. Foreign matter adhering to the surface of the radiator

散热器表面附着杂物会使散热器散热面积减小，散热器的迎风面积减小，导致散热器的散热能力降低，引起柴油机高温6、风扇皮带过松或风扇变形

The attachment of debris on the surface of the radiator will reduce the heat dissipation area of the radiator, decrease the windward area of the radiator, and reduce the heat dissipation capacity of the radiator, causing high temperature in the diesel engine. 6. The fan belt is too loose or the fan is deformed

风扇皮带过松，容易造成风扇转速降低，造成散热器不能发挥应有的散热能力，导致柴油机温度过高。此外，风扇变形也会导致散热器的散热能力不能充分发挥。对此，应定期检查柴油机风扇皮带是否松弛及风扇形状是否异常。

Loose fan belts can easily cause a decrease in fan speed, resulting in the radiator not being able to dissipate heat properly and causing the diesel engine to overheat. In addition, deformation of the fan can also lead to insufficient heat dissipation capacity of the radiator. Regular checks should be conducted on whether the diesel engine fan belt is loose and whether the fan shape is abnormal.
