安慶200kw發電機組必須保證充足的空氣流通，以排放發動機、發電機及其附屬設備產生的熱量，煙霧和廢氣，并補充燃燒所需空氣。通風氣流應保證機房溫升低于10度。柴油發電機組的冷卻系統是封閉式，冷卻介質都是循環使用的。所采用的冷卻介質一般為空氣、氫氣和水三種。空氣冷卻：空氣冷卻都是采用風扇送風的方式，用冷空氣對著柴油發電機組繞組端部，發電機組定子和轉子進行吹拂散熱的，冷空氣吸取熱量后變為熱空氣，在定子和轉子之間的氣息初匯合后，在經鐵芯的風道排出，通過冷卻器進行冷卻。

200kw發電機組被冷卻后的空氣再由風扇送入發電機內部循環使用，以達到散熱的目的。氫氣冷卻：氫氣冷卻都是采用氫氣作為冷卻介質，氫氣的散熱性能都比空氣的散熱性能好。水冷卻：水冷卻是采用定子，轉子雙水內冷的方式。由于水的散熱性能遠高于空氣和氫氣，因此，大型的發電機組一般都采用水冷卻方式。

當前國內許(xu)多(duo)高(gao)(gao)層(ceng)建(jian)筑都采用(yong)柴油發電機(ji)(ji)(ji)組進(jin)行供電，但是高(gao)(gao)層(ceng)建(jian)筑對柴油機(ji)(ji)(ji)組的供電要(yao)求(qiu)可靠性(xing)較高(gao)(gao)，所以一(yi)般的機(ji)(ji)(ji)組根本無(wu)法滿足(zu)高(gao)(gao)層(ceng)建(jian)筑的使用(yong)規范。200kw發電機(ji)(ji)(ji)組配件講(jiang)解一(yi)下高(gao)(gao)層(ceng)建(jian)筑的選擇要(yao)求(qiu)：啟動(dong)方式。機(ji)(ji)(ji)組在啟動(dong)時，必須靠外力(li)驅動(dong)曲(qu)軸旋轉，當達到(dao)(dao)一(yi)定轉速(su)時，氣缸內的空(kong)氣被壓縮到(dao)(dao)一(yi)定壓力(li)和溫度，使噴進(jin)氣缸的燃油開始(shi)燃燒，柴油機(ji)(ji)(ji)才開始(shi)運轉起來。
