玉柴柴油发电机组出水温度过高故障特征和产生原因:
Failure characteristics and causes of outlet water high temperature of diesel generator
1、水管中有空气:柴油发电机起动后出水管不出水或水量很少,水温不断升高,请松开出水管上的温度表接头,放尽空气到出水畅通为止,拧紧水管路中各接头。
Air in the water pipe.After the generator started,with the rising water temperature,Please loosen the temperature gauge connector of the outlet pipe, drain the air until the water is unblocked, and tighten the joints of the pipe.
2、循环水量不足:在高负荷下,出水温度过高,机油温度也升高。
Insufficient circulating water,Under high load, the temperature of thewater is too high, and the oil temperature also rises. 
(1)淡水泵或风扇转速达不到 Pump or fan speed failed  
(2)淡水泵叶轮损坏 Pump impeller damaged
(3)淡水泵叶轮与壳体的间隙过大 Too large gap between the pump impeller and the casing
(4)开式循环中,水源水位过低,淡水泵吸不上水 
In open circulation, water level is too low,pump can not absorb water. 
(5)闭式循环中,散热器水量不足 
Insufficient radiator water in closed circulation
(6)水管路阻塞 Water pipe blocking
处理方法:Solution
1、提高水源水位,添加冷却水清理管路,清除冷却水道中的积垢。
Raise water level, add cooling water to clean pipeline and remove dirt in cooling water.
2、闭式循环中,散热器表面积垢太多,影响散热,清除积垢。
In the closed cycle,the radiator surface accumulated too much dirt,affecting the heat dissipation,please remove the dirt accumulation.
3、更换失灵的调温器。Replace the failed thermostat.
4、水温表不正确修理或更换。Repair or replace the wrong temperature gauge.
5、气缸套肩胛处有裂纹:此时散热器内冷却水有翻泡现象,更换汽缸套。
There crack at the cylinder liner.And the cooling water of radiator is bubbling,please replace the cylinder liner.
