6月28日，由哈(ha)電集團（秦(qin)皇(huang)島）重型裝備有(you)限公司（以(yi)下簡稱“哈(ha)電重裝”）承制的巴基斯(si)坦卡拉奇項目(mu)穩(wen)壓(ya)(ya)器(qi)（簡稱K3項目(mu)穩(wen)壓(ya)(ya)器(qi)）產成發(fa)運。
K3項目穩壓(ya)器是對一回(hui)路壓(ya)力進行控(kong)制和超(chao)壓(ya)保護的(de)重(zhong)要設備，采用立式(shi)電(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱式(shi)，結構(gou)呈鐘罩(zhao)形，總長度約13763mm,總重(zhong)量約104t；上封頭(tou)(tou)頂部設有(you)5只閥(fa)門接管(guan)、1只噴霧(wu)頭(tou)(tou)接管(guan)及(ji)1只人孔(kong)(kong)座；底部設置84根電(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱元件及(ji)1只波動接管(guan)。哈(ha)電(dian)(dian)(dian)(dian)重(zhong)裝(zhuang)(zhuang)先后(hou)攻克了(le)(le)封頭(tou)(tou)及(ji)筒(tong)體(ti)內壁堆焊(han)(han)、封頭(tou)(tou)電(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱套(tao)管(guan)冷裝(zhuang)(zhuang)孔(kong)(kong)加(jia)(jia)(jia)(jia)工、電(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱元件裝(zhuang)(zhuang)配及(ji)焊(han)(han)接等技術難點，為產品的(de)順利(li)發(fa)運奠定了(le)(le)堅實的(de)基礎。
作為(wei)我國(guo)出(chu)口(kou)“華龍一號(hao)”核(he)電(dian)(dian)(dian)機組的重(zhong)要組成(cheng)部(bu)分，K3項(xiang)目穩壓器的成(cheng)功發運，標志著由哈(ha)電(dian)(dian)(dian)重(zhong)裝承制的巴基(ji)斯坦卡拉奇項(xiang)目產品(pin)全部(bu)完成(cheng)交(jiao)貨。哈(ha)電(dian)(dian)(dian)重(zhong)裝歷(li)時5年時間，成(cheng)功為(wei)“華龍一號(hao)”首臺(tai)出(chu)口(kou)巴基(ji)斯坦的K2、K3核(he)電(dian)(dian)(dian)項(xiang)目提供全部(bu)核(he)島主設備蒸(zheng)汽發生器、穩壓器，PRS換熱(re)器、PCS換熱(re)器、余熱(re)排出(chu)熱(re)交(jiao)換器也按(an)計劃實現(xian)交(jiao)付。
哈電重裝(zhuang)通(tong)過自主研(yan)發(fa)(fa)、技(ji)術(shu)(shu)(shu)引進(jin)和創新、設計工(gong)(gong)(gong)藝優(you)化等(deng)多(duo)種(zhong)方(fang)式(shi)，形成了一整(zheng)套“華龍(long)一號”的(de)配套裝(zhuang)備(bei)(bei)和技(ji)術(shu)(shu)(shu)儲備(bei)(bei)。在項目(mu)進(jin)行(xing)過程中(zhong)，哈電重裝(zhuang)在傳統的(de)制(zhi)造工(gong)(gong)(gong)藝基礎(chu)上(shang)，不斷改進(jin)工(gong)(gong)(gong)藝方(fang)法(fa)和技(ji)術(shu)(shu)(shu)措施，重點(dian)突(tu)破了蒸汽(qi)發(fa)(fa)生器(qi)管(guan)(guan)板(ban)鎳基合(he)金堆焊(han)(han)、管(guan)(guan)束組件(jian)制(zhi)造、管(guan)(guan)子(zi)—管(guan)(guan)板(ban)脹焊(han)(han)技(ji)術(shu)(shu)(shu)、管(guan)(guan)子(zi)壓(ya)(ya)痕預(yu)防(fang)技(ji)術(shu)(shu)(shu)、水平支承連(lian)接板(ban)焊(han)(han)接及防(fang)變形技(ji)術(shu)(shu)(shu)以及穩壓(ya)(ya)器(qi)封頭及筒體內壁堆焊(han)(han)、封頭電加熱套管(guan)(guan)冷裝(zhuang)孔加工(gong)(gong)(gong)、電加熱元件(jian)裝(zhuang)配及焊(han)(han)接等(deng)關(guan)鍵(jian)(jian)技(ji)術(shu)(shu)(shu)，隨著首臺(tai)產品(pin)水壓(ya)(ya)試驗的(de)成功，所有關(guan)鍵(jian)(jian)技(ji)術(shu)(shu)(shu)的(de)研(yan)發(fa)(fa)得(de)到最終驗證。在此期間，華龍(long)一號蒸汽(qi)發(fa)(fa)生器(qi)產品(pin)被列為河北省重點(dian)領域首臺(tai)（套）重大(da)技(ji)術(shu)(shu)(shu)裝(zhuang)備(bei)(bei)產品(pin)公告目(mu)錄，《華龍(long)一號ZH-65型(xing)蒸汽(qi)發(fa)(fa)生器(qi)關(guan)鍵(jian)(jian)工(gong)(gong)(gong)藝研(yan)究》順(shun)利通(tong)過核能(neng)行(xing)業協會(hui)鑒定，并(bing)榮獲(huo)中(zhong)國核能(neng)行(xing)業協會(hui)科技(ji)進(jin)步獎(jiang)二等(deng)獎(jiang)。
卡拉奇項目產品的(de)(de)整(zheng)體完工，對(dui)(dui)促進(jin)哈電(dian)(dian)(dian)(dian)集團(tuan)核(he)(he)電(dian)(dian)(dian)(dian)產業發展(zhan)、提升核(he)(he)電(dian)(dian)(dian)(dian)裝(zhuang)備市(shi)場(chang)地位起到了(le)關鍵作用，為提高中國(guo)核(he)(he)電(dian)(dian)(dian)(dian)裝(zhuang)備制造產業的(de)(de)整(zheng)體制造水(shui)平(ping)作出(chu)了(le)應有的(de)(de)貢(gong)獻，也(ye)是哈電(dian)(dian)(dian)(dian)集團(tuan)在“一帶一路”建設中踐行中國(guo)核(he)(he)電(dian)(dian)(dian)(dian)“走出(chu)去(qu)”戰略的(de)(de)具體體現，同時對(dui)(dui)中國(guo)核(he)(he)電(dian)(dian)(dian)(dian)產業進(jin)一步拓展(zhan)海外核(he)(he)電(dian)(dian)(dian)(dian)裝(zhuang)備市(shi)場(chang)、帶動核(he)(he)電(dian)(dian)(dian)(dian)技術裝(zhuang)備走出(chu)去(qu)產生了(le)積極影響。
據了(le)解，2019年是(shi)“華龍(long)一號”項目(mu)海外首堆的關(guan)鍵之年，距我(wo)國首都(dou)北京(jing)3800公里(li)以外的卡拉(la)奇核電站于當(dang)地時間2019年6月17日(ri)完(wan)成了(le)K2機(ji)組外層安(an)(an)全殼穹頂(ding)吊裝(zhuang)工作，為(wei)后續(xu)安(an)(an)全殼整體熱試(shi)和試(shi)驗創(chuang)造了(le)有利的條(tiao)件(jian)。2019年6月22日(ri)，K2機(ji)組核回路（NCC)冷試(shi)正式開始(shi)，標志著核島主(zhu)要輔助系統主(zhu)體安(an)(an)裝(zhuang)工程圓滿(man)結束。
