In the process of using the diesel generator set, the water temperature is easy to be too high. Let's analyze several reasons for the high water temperature of the diesel generator.

1、柴油發電機未加足冷卻水，或冷卻系統漏水而耗水過多高。

1. The diesel generator does not add enough cooling water, or the cooling system leaks and the water consumption is too high.

2、未按規定清洗冷卻系統，因水垢積累太多或雜物堵塞水箱散熱器芯管．冷卻水循環能力不強，冷卻效果差。

2. The cooling system was not cleaned as required, and the radiator core pipe of the water tank was blocked due to too much scale accumulation or sundries. The cooling water circulation capacity was not strong and the cooling effect was poor.

3、風扇皮帶太松或損壞，或風扇葉片變形使風量不足，降低風冷效果；或風扇皮帶打滑導致柴油發電機的水泵軸轉速減慢，泵水量不足或不泵水。

3. The fan belt is too loose or damaged, or the fan blade is deformed, resulting in insufficient air volume and reducing the air cooling effect; Or the fan belt slips, causing the speed of the water pump shaft of the diesel generator to slow down, and the water pump is insufficient or does not pump water.

4、水泵內局部堵塞或磨損過度漏水。

4. Local blockage or excessive wear and water leakage in the water pump.

5、節溫器膨脹筒損壞，節溫器失效。

5. The expansion cylinder of the thermostat is damaged and the thermostat fails.

6、發動機保溫簾或百葉窗未開啟妨礙散熱。

6. The thermal insulation curtain or shutter of the engine is not opened, which hinders heat dissipation.

7、發動機超負荷工作，引起水溫過高等。

7. The engine is overloaded, causing high water temperature.

8、柴油發電機噴油量過大，造成混合氣過濃，緩燃期、補燃期相應延長，而使水溫過高。

8. The fuel injection quantity of diesel generator is too large, resulting in too rich mixture, corresponding extension of slow combustion period and supplementary combustion period, resulting in too high water temperature.
