12月6日，由(you)哈電(dian)汽(qi)輪機設(she)計制(zhi)造的甘肅電(dian)投常樂1號(hao)汽(qi)輪機組實現一(yi)次扣蓋(gai)成功。此次扣缸(gang)范(fan)圍(wei)包(bao)括中(zhong)壓(ya)(ya)模(mo)塊(kuai)、低(di)壓(ya)(ya)1號(hao)和低(di)壓(ya)(ya)2號(hao)模(mo)塊(kuai)。

甘肅電(dian)投(tou)常樂汽(qi)(qi)(qi)(qi)(qi)輪機(ji)是哈電(dian)汽(qi)(qi)(qi)(qi)(qi)輪機(ji)首臺高(gao)效超超臨(lin)界百萬(wan)空(kong)冷機(ji)組，為一(yi)次(ci)中(zhong)間再(zai)熱(re)(re)、四缸(gang)四排汽(qi)(qi)(qi)(qi)(qi)、單(dan)軸、間接(jie)空(kong)冷凝汽(qi)(qi)(qi)(qi)(qi)式(shi)汽(qi)(qi)(qi)(qi)(qi)輪機(ji)。整個(ge)(ge)汽(qi)(qi)(qi)(qi)(qi)輪機(ji)發(fa)電(dian)機(ji)組總長50.3米(mi)，其中(zhong)汽(qi)(qi)(qi)(qi)(qi)輪機(ji)長32.96米(mi)。機(ji)組匯集(ji)了多(duo)項哈電(dian)集(ji)團最先進的(de)科研成果。高(gao)壓(ya)部分整體發(fa)貨(huo)，內缸(gang)采(cai)(cai)用(yong)(yong)紅套環安(an)裝(zhuang)(zhuang)；進汽(qi)(qi)(qi)(qi)(qi)方(fang)式(shi)采(cai)(cai)用(yong)(yong)無調(diao)節(jie)級、全周進汽(qi)(qi)(qi)(qi)(qi)、單(dan)流程蝸殼進汽(qi)(qi)(qi)(qi)(qi)；高(gao)壓(ya)主(zhu)汽(qi)(qi)(qi)(qi)(qi)調(diao)節(jie)閥對稱布(bu)置(zhi)(zhi)在高(gao)壓(ya)缸(gang)兩側，與汽(qi)(qi)(qi)(qi)(qi)缸(gang)法蘭連接(jie)，彈性(xing)支(zhi)(zhi)架支(zhi)(zhi)撐(cheng)。中(zhong)壓(ya)部分現(xian)場組裝(zhuang)(zhuang)、散件發(fa)貨(huo)；中(zhong)壓(ya)模塊(kuai)采(cai)(cai)用(yong)(yong)雙(shuang)分流布(bu)置(zhi)(zhi)進汽(qi)(qi)(qi)(qi)(qi)；再(zai)熱(re)(re)主(zhu)汽(qi)(qi)(qi)(qi)(qi)調(diao)節(jie)閥對稱布(bu)置(zhi)(zhi)在中(zhong)壓(ya)缸(gang)兩側與中(zhong)壓(ya)缸(gang)剛(gang)性(xing)焊接(jie)，彈簧支(zhi)(zhi)撐(cheng)。低(di)壓(ya)部分現(xian)場組裝(zhuang)(zhuang)，散件發(fa)貨(huo)；低(di)壓(ya)模塊(kuai)采(cai)(cai)用(yong)(yong)雙(shuang)分流布(bu)置(zhi)(zhi)蝸殼進汽(qi)(qi)(qi)(qi)(qi)、第一(yi)級橫置(zhi)(zhi)靜(jing)葉；軸承(cheng)箱落(luo)地布(bu)置(zhi)(zhi)、采(cai)(cai)用(yong)(yong)落(luo)地內缸(gang)、落(luo)地端汽(qi)(qi)(qi)(qi)(qi)封(feng)等技(ji)術。整個(ge)(ge)汽(qi)(qi)(qi)(qi)(qi)輪機(ji)通流設(she)計采(cai)(cai)用(yong)(yong)高(gao)效的(de)“多(duo)級數反動(dong)(dong)式(shi)”設(she)計，配(pei)備預扭裝(zhuang)(zhuang)配(pei)式(shi)動(dong)(dong)、靜(jing)葉片，采(cai)(cai)用(yong)(yong)先進AIS汽(qi)(qi)(qi)(qi)(qi)封(feng)設(she)計技(ji)術，較(jiao)大的(de)提高(gao)機(ji)組效率。

在機(ji)組生(sheng)產(chan)過程(cheng)(cheng)中(zhong)，哈電(dian)(dian)汽輪機(ji)嚴(yan)格(ge)按照精(jing)品工(gong)程(cheng)(cheng)的要求和策(ce)劃方案，作了全面細致(zhi)的部署(shu)，確保產(chan)品高質量(liang)生(sheng)產(chan)制造并于2019年4月完成(cheng)了廠內生(sheng)產(chan)開(kai)始陸續發貨。在機(ji)組安裝過程(cheng)(cheng)中(zhong)，哈電(dian)(dian)汽輪機(ji)現場(chang)服務人員，本著事事有回(hui)應、件(jian)件(jian)有落(luo)實的原則，不畏烈(lie)日嚴(yan)寒、克(ke)服困難，與業主方、上海電(dian)(dian)建常樂(le)項目部、監理單位(wei)共同(tong)努力(li)，全力(li)打造常樂(le)精(jing)品工(gong)程(cheng)(cheng)。
