柴油發電機的基本結構

柴油發電機的基本結構

    柴油發電機的基本結構是由柴油機和發電機組成柴油機作動力帶動發電機發電。

    柴油機的基本結構是由氣缸
、活塞、氣缸蓋、進氣門
、排氣門
、活塞銷、連杆、曲軸
、軸承和(he)飛(fei)輪(lun)等(deng)構(gou)件(jian)構(gou)成(cheng)。柴(chai)油(you)發(fa)電(dian)機(ji)的(de)柴(chai)油(you)機(ji)一(yi)般(ban)是(shi)單(dan)缸(gang)或(huo)多(duo)缸(gang)四(si)行(xing)程(cheng)的(de)柴(chai)油(you)機(ji)下(xia)麵(mian)我(wo)隻(zhi)說(shuo)說(shuo)單(dan)缸(gang)四(si)行(xing)程(cheng)柴(chai)油(you)機(ji)的(de)工(gong)作(zuo)基(ji)本(ben)原(yuan)理(li)柴(chai)油(you)機(ji)起(qi)動(dong)是(shi)通(tong)過(guo)人(ren)力(li)或(huo)其(qi)它(ta)動(dong)力(li)轉(zhuan)動(dong)柴(chai)油(you)機(ji)曲(qu)軸(zhou)使(shi)活(huo)塞(sai)在(zai)頂(ding)部(bu)密(mi)閉(bi)的(de)氣(qi)缸(gang)中(zhong)作(zuo)上(shang)下(xia)往(wang)複(fu)運(yun)動(dong)。活(huo)塞(sai)在(zai)運(yun)動(dong)中(zhong)完(wan)成(cheng)四(si)個(ge)行(xing)程(cheng)進(jin)氣(qi)行(xing)程(cheng)
