發(fā)電機組配件在運作當中會出現(xiàn)“發(fā)燒”的現(xiàn)象，過熱可能是由于發(fā)動機溫度過高，風扇皮帶過緊及調整器限額電流凋整不當引起，也可能由于本身的原因。這時候應該對發(fā)電設備進行檢查維修，如果檢查到冷卻水和機油的溫度長時間超出正常許用值，則說明該發(fā)電機組配件出現(xiàn)了過熱故障。
The generator set accessories will have a "fever" phenomenon during operation. The overheating may be caused by too high engine temperature, too tight fan belt and improper adjustment of the regulator limit current, or it may be due to its own reasons. At this time, the power generation equipment should be inspected and maintained. If the temperature of cooling water and oil exceeds the normal allowable value for a long time, it indicates that the generator set accessories have overheated fault.
主要原因有以下幾種：
The main reasons are as follows:
1、機體與缸蓋的水道里雜質沉積太多，使水循環(huán)不暢通，機油損耗過多也會引起散熱不良。
1. There are too many impurities in the water channel between the engine body and the cylinder head, which makes the water circulation not smooth. Excessive oil loss will also cause poor heat dissipation.
2、*使用硬水，導致水箱水道形成大量水垢，導致散熱不良。
2. * The use of hard water causes a large amount of scale to form in the water channel of the water tank, resulting in poor heat dissipation.
3、冷卻系統(tǒng)有堵塞現(xiàn)象。由于減少了機油的冷卻效果，發(fā)電設備各摩擦副的熱量傳不出來，也會導致機體過熱。散熱、冷卻、潤滑系統(tǒng)的堵塞，都會導致柴油機過熱。
3. The cooling system is blocked. As the cooling effect of the engine oil is reduced, the heat of the friction pairs of the power generation equipment cannot be transferred, which will also lead to overheating of the engine body. Blockage of heat dissipation, cooling and lubrication systems will cause overheating of the diesel engine.
4、操作不當，啟動時應先用中小油門預熱一段時間，不能突然加大油門，猛加負荷，否則會使柴油發(fā)電機工作粗暴，溫度猛增。
4. If the operation is improper, the medium and small throttle should be used to preheat for a period of time before starting. Do not suddenly increase the throttle and load, otherwise the diesel generator will work rough and the temperature will increase sharply.

5、長時間超負荷運行,導致溫度過高。
5. Overload operation for a long time leads to high temperature.
6、供油時間遲緩而引起機體過熱，機油泵漏油都是其中原因
6. The engine overheats due to the slow oil supply time, and the oil leakage of the oil pump is the cause
7、冷卻系統(tǒng)、潤滑油系統(tǒng)出現(xiàn)泄漏，也是導致柴油機過熱的主要原因。
7. Leakage of cooling system and lubricating oil system is also the main cause of overheating of diesel engine.
同時機器的三相負荷電流不平衡，過載的一相繞組會過熱;若三相電流之差超過額定電流的10%，即屬于嚴重蛄相電流不平衡，三相電流不平衡會產生負序磁場，從而增加損耗，引起磁極繞組及套箍等部件發(fā)熱。這也是常見的一個問題。
At the same time, the three-phase load current of the machine is unbalanced, and the overload one-phase winding will overheat; If the difference of the three-phase current exceeds 10% of the rated current, it is a serious three-phase current imbalance. The three-phase current imbalance will generate negative sequence magnetic field, which will increase the loss and cause the heating of the magnetic pole winding, sleeve and other components. This is also a common problem.
了解到了原因，在遇到溫度過熱的時候也不用慌手慌腳了，可以很得心應手的處理，恢復設備的正常運行。
After understanding the reason, you don't have to panic when the temperature is too high. You can handle it easily and restore the normal operation of the equipment.
