上海發電機(ji)組回收(shou)公司長期高(gao)價提供發電機(ji)組回收(shou)服務。發(fa)電(dian)(dian)機組在(zai)柴油(you)機發(fa)電(dian)(dian)機組體(ti)積(ji)縮小(xiao)溫度迅(xun)速(su)升高，達到(dao)柴油(you)的(de)燃點。柴油(you)被點燃，混合氣體(ti)劇烈(lie)燃燒，體(ti)積(ji)迅(xun)速(su)膨脹，推(tui)動活(huo)塞下行，稱(cheng)為‘作功’。各汽缸按一定順(shun)序依次(ci)作功，作用(yong)在(zai)活(huo)塞上的(de)推(tui)力經(jing)過連(lian)桿(gan)變(bian)成了推(tui)動曲軸轉動的(de)力量(liang)，從而(er)帶動曲軸旋轉。利用(yong)‘電(dian)(dian)磁感應(ying)’原(yuan)理(li)，發(fa)電(dian)(dian)機就會輸(shu)出感應(ying)電(dian)(dian)動勢，經(jing)閉合的(de)負載(zai)回路就能產生電(dian)(dian)流。這里(li)只(zhi)描述發(fa)電(dian)(dian)機組最基本(ben)的(de)工作原(yuan)理(li)。要想(xiang)得(de)到(dao)可(ke)使用(yong)的(de)、穩(wen)定的(de)電(dian)(dian)力輸(shu)出，還(huan)需要一系(xi)列的(de)柴油(you)機和發(fa)電(dian)(dian)機控制、保(bao)護器件和回路。
一、上海發電機回收產品的分類

6、機組起動方式的選(xuan)擇(ze)。
柴油機(ji)的起(qi)(qi)動(dong)(dong)方(fang)(fang)式有三種：①手(shou)搖起(qi)(qi)動(dong)(dong)；②電動(dong)(dong)起(qi)(qi)動(dong)(dong)；③壓(ya)縮空(kong)氣(qi)起(qi)(qi)動(dong)(dong)。在(zai)高層(ceng)建筑中(zhong)宜采用(yong)電起(qi)(qi)動(dong)(dong)方(fang)(fang)式，避免采用(yong)壓(ya)縮空(kong)氣(qi)起(qi)(qi)動(dong)(dong)方(fang)(fang)式。一類高層(ceng)建筑中(zhong)一定要選擇(ze)帶自(zi)起(qi)(qi)動(dong)(dong)裝置(zhi)的柴油發電機(ji)組，一旦(dan)市網供電中(zhong)斷，必須在(zai)15秒(miao)內供電(高規要求30秒(miao))。二類高層(ceng)建筑中(zhong)有條件時，也(ye)宜采用(yong)帶自(zi)起(qi)(qi)動(dong)(dong)裝置(zhi)的機(ji)組，有困難時也(ye)可(ke)采用(yong)手(shou)動(dong)(dong)起(qi)(qi)動(dong)(dong)裝置(zhi)。
7、性能和質量必須(xu)符合有關標準要求(qiu)。
作為(wei)(wei)通(tong)信用(yong)柴(chai)油(you)發(fa)電(dian)機(ji)組，必須(xu)(xu)達到GB2820-1997中G3級或G4級規定(ding)的(de)(de)(de)(de)要(yao)(yao)求和《通(tong)信用(yong)柴(chai)油(you)發(fa)電(dian)機(ji)組的(de)(de)(de)(de)進網質(zhi)量(liang)(liang)認證檢測實施細則》規定(ding)的(de)(de)(de)(de)24項性(xing)能指(zhi)標要(yao)(yao)求，同時要(yao)(yao)通(tong)過通(tong)信電(dian)源設備(bei)質(zhi)量(liang)(liang)監督檢驗中心的(de)(de)(de)(de)嚴(yan)格(ge)檢驗。作為(wei)(wei)軍事(shi)通(tong)信用(yong)柴(chai)油(you)發(fa)電(dian)機(ji)組，必須(xu)(xu)達到有(you)(you)(you)關GB2820-1997、GJB相關標準(zhun)和部隊(dui)有(you)(you)(you)關部門制定(ding)的(de)(de)(de)(de)《通(tong)信電(dian)源設備(bei)的(de)(de)(de)(de)質(zhi)量(liang)(liang)檢測標準(zhun)》的(de)(de)(de)(de)規定(ding)，并要(yao)(yao)通(tong)過有(you)(you)(you)關組織部門對(dui)設備(bei)質(zhi)量(liang)(liang)的(de)(de)(de)(de)嚴(yan)格(ge)檢驗。
8、與三相電(dian)動機匹配(pei)需注意的(de)問題。
發(fa)電(dian)機組與三相電(dian)機容(rong)量選(xuan)配時，建(jian)議考慮安全系數1.5，即1.5倍的電(dian)機容(rong)量(必需是(shi)軟啟動方式)。
9、注意(yi)額定(ding)功率(lv)(lv)和后備功率(lv)(lv)的(de)關(guan)系，KVA和KW的(de)關(guan)系。
市場上有(you)些(xie)廠家僅說一個(ge)“功(gong)(gong)(gong)率(lv)(lv)(lv)”，把后(hou)備功(gong)(gong)(gong)率(lv)(lv)(lv)當作額定(ding)功(gong)(gong)(gong)率(lv)(lv)(lv)來介(jie)紹(shao)和(he)銷(xiao)售機(ji)組(zu)。實(shi)際(ji)上后(hou)備功(gong)(gong)(gong)率(lv)(lv)(lv)=1.1x額定(ding)功(gong)(gong)(gong)率(lv)(lv)(lv)。而且后(hou)備功(gong)(gong)(gong)率(lv)(lv)(lv)只能在(zai)12小(xiao)時連(lian)續運行(xing)中使用1小(xiao)時。在(zai)國內普(pu)遍(bian)都是用額定(ding)功(gong)(gong)(gong)率(lv)(lv)(lv)來標識(shi)柴油(you)發電機(ji)組(zu)的，而在(zai)國際(ji)上是采用備用功(gong)(gong)(gong)率(lv)(lv)(lv)來標識(shi)。KVA是視(shi)在(zai)功(gong)(gong)(gong)率(lv)(lv)(lv)，KW是有(you)效(xiao)功(gong)(gong)(gong)率(lv)(lv)(lv)，他(ta)們之間的關(guan)系為IKVA=0.8KW。進口機(ji)組(zu)一般用KVA表(biao)示(shi)功(gong)(gong)(gong)率(lv)(lv)(lv)單位，而國內用電設備一般都用KW表(biao)示(shi)。
10、認清機(ji)組的(de)品牌。
一般進(jin)口(kou)的(de)發(fa)(fa)電機(ji)組(zu)(zu)(zu)(zu)均為組(zu)(zu)(zu)(zu)裝(zhuang)機(ji)，但對國產(chan)(chan)機(ji)組(zu)(zu)(zu)(zu)來說，有一體化的(de)機(ji)組(zu)(zu)(zu)(zu)（即發(fa)(fa)電機(ji)和發(fa)(fa)動機(ji)是同一品(pin)牌(pai)），雖體積比進(jin)口(kou)的(de)大，但在(zai)性能上也(ye)同有些進(jin)口(kou)機(ji)組(zu)(zu)(zu)(zu)不(bu)分上下，而且價格便宜，故在(zai)選購(gou)時(shi)應(ying)全面了解機(ji)組(zu)(zu)(zu)(zu)的(de)柴油機(ji)、發(fa)(fa)電機(ji)、控制柜的(de)制造(zao)廠家及品(pin)牌(pai)（因有些廠家只(zhi)報柴油機(ji)或發(fa)(fa)電機(ji)品(pin)牌(pai)，不(bu)報產(chan)(chan)地(di)，不(bu)報機(ji)組(zu)(zu)(zu)(zu)品(pin)牌(pai)等），才能綜(zong)合評估出機(ji)組(zu)(zu)(zu)(zu)的(de)檔次(ci)。
三、上海發(fa)電機組回收(shou)產品的機組耗油量(liang)
很多客戶在選擇(ze)發(fa)(fa)電(dian)(dian)機(ji)(ji)組的(de)(de)(de)時(shi)(shi)(shi)候會考(kao)慮到(dao)耗油(you)量這(zhe)(zhe)塊，很多用戶在選擇(ze)前都(dou)會對參數(shu)上所(suo)標(biao)識的(de)(de)(de)數(shu)字很不(bu)(bu)了(le)解，像(xiang)一(yi)臺(tai)5KW的(de)(de)(de)汽油(you)發(fa)(fa)電(dian)(dian)機(ji)(ji)組它的(de)(de)(de)耗油(you)量會標(biao)著(zhu) 540g/KW/h 意思就是(shi)(shi)(shi)(shi)每(mei)(mei)KW每(mei)(mei)小耗油(you)540g，很多客戶會以為(wei)是(shi)(shi)(shi)(shi)這(zhe)(zhe)臺(tai)發(fa)(fa)電(dian)(dian)機(ji)(ji)是(shi)(shi)(shi)(shi)540g一(yi)個(ge)小時(shi)(shi)(shi)。其實不(bu)(bu)是(shi)(shi)(shi)(shi)這(zhe)(zhe)樣(yang)的(de)(de)(de)，是(shi)(shi)(shi)(shi)540g 1KW一(yi)個(ge)小時(shi)(shi)(shi)，也就是(shi)(shi)(shi)(shi)說(shuo)這(zhe)(zhe)臺(tai)機(ji)(ji)器(qi)滿負載時(shi)(shi)(shi)是(shi)(shi)(shi)(shi)1個(ge)千(qian)瓦是(shi)(shi)(shi)(shi)540g 5千(qian)瓦就是(shi)(shi)(shi)(shi)5個(ge)540g。當(dang)然看這(zhe)(zhe)里很客戶都(dou)會覺得發(fa)(fa)電(dian)(dian)機(ji)(ji)耗油(you)太厲害了(le)，但是(shi)(shi)(shi)(shi)我剛才說(shuo)的(de)(de)(de)是(shi)(shi)(shi)(shi)滿負載的(de)(de)(de)情況下(xia)是(shi)(shi)(shi)(shi)這(zhe)(zhe)樣(yang)算的(de)(de)(de)。所(suo)以說(shuo)實際耗油(you)是(shi)(shi)(shi)(shi)達(da)不(bu)(bu)到(dao)這(zhe)(zhe)么多的(de)(de)(de)，因為(wei)發(fa)(fa)電(dian)(dian)機(ji)(ji)帶(dai)設備都(dou)會有一(yi)個(ge)啟動電(dian)(dian)流，所(suo)以說(shuo)一(yi)般(ban)買一(yi)個(ge)5千(qian)瓦汽油(you)發(fa)(fa)電(dian)(dian)機(ji)(ji)是(shi)(shi)(shi)(shi)不(bu)(bu)會5個(ge)千(qian)瓦都(dou)用上的(de)(de)(de)，還有如果你的(de)(de)(de)所(suo)帶(dai)的(de)(de)(de)設備功率不(bu)(bu)大的(de)(de)(de)話，發(fa)(fa)電(dian)(dian)機(ji)(ji)所(suo)耗的(de)(de)(de)油(you)只有1/3。
所以發電機組油(you)耗(hao)這(zhe)一塊的話，其(qi)實(shi)不必在(zai)意太(tai)多(duo)。希望這(zhe)篇文章對您有(you)幫助(zhu)，有(you)什么問題可以直接和網站客(ke)服聯系，也可以直接撥(bo)打網站熱線咨詢。
四、上海發電機組回收產品的國家產量
2011年(nian)，中國(guo)發(fa)電(dian)機及發(fa)電(dian)機組(zu)制造行業(ye)仍保持較快的速度發(fa)展(zhan)。2011年(nian)底全國(guo)規模以上(shang)發(fa)電(dian)機及發(fa)電(dian)機組(zu)制造企業(ye)有704家(jia)，實現(xian)工業(ye)總產值3014.72億元(yuan)(yuan)(yuan)；資產合計3158.31億元(yuan)(yuan)(yuan)，同比(bi)增長27.07%；實現(xian)銷售收入(ru)2900.69億元(yuan)(yuan)(yuan)，同比(bi)增長19.54%；完成(cheng)利潤總額184.37億元(yuan)(yuan)(yuan)，同比(bi)下降10.06%。
根據2004-2011年發(fa)電(dian)(dian)機(ji)(ji)及發(fa)電(dian)(dian)機(ji)(ji)組(zu)制造(zao)行(xing)(xing)業的歷史數據，分(fen)析其(qi)數據特征，算(suan)出行(xing)(xing)業年平均增長率，對 2012年發(fa)電(dian)(dian)機(ji)(ji)及發(fa)電(dian)(dian)機(ji)(ji)組(zu)制造(zao)行(xing)(xing)業的銷(xiao)售(shou)收(shou)入和利潤(run)總(zong)額(e)(e)進行(xing)(xing)預測(ce)。預計(ji)2012年，發(fa)電(dian)(dian)機(ji)(ji)及發(fa)電(dian)(dian)機(ji)(ji)組(zu)制造(zao)行(xing)(xing)業銷(xiao)售(shou)收(shou)入將超4000億(yi)(yi)元(yuan)，利潤(run)總(zong)額(e)(e)超過250億(yi)(yi)元(yuan)。
伴隨(sui)行(xing)業(ye)市場規模的(de)(de)(de)不(bu)斷擴大(da)，發(fa)(fa)(fa)電(dian)(dian)(dian)機(ji)(ji)及(ji)(ji)(ji)發(fa)(fa)(fa)電(dian)(dian)(dian)機(ji)(ji)組制造行(xing)業(ye)的(de)(de)(de)競(jing)爭將進一步加劇，國內優秀的(de)(de)(de)發(fa)(fa)(fa)電(dian)(dian)(dian)機(ji)(ji)及(ji)(ji)(ji)發(fa)(fa)(fa)電(dian)(dian)(dian)機(ji)(ji)組制造企業(ye)也(ye)越(yue)來越(yue)重視對(dui)行(xing)業(ye)市場的(de)(de)(de)研究，特(te)別(bie)是對(dui)產業(ye)購買者的(de)(de)(de)深入研究。也(ye)正因為如此(ci)，一大(da)批國內優秀的(de)(de)(de)發(fa)(fa)(fa)電(dian)(dian)(dian)機(ji)(ji)及(ji)(ji)(ji)發(fa)(fa)(fa)電(dian)(dian)(dian)機(ji)(ji)組生產企業(ye)迅速崛起，逐漸成(cheng)為發(fa)(fa)(fa)電(dian)(dian)(dian)機(ji)(ji)及(ji)(ji)(ji)發(fa)(fa)(fa)電(dian)(dian)(dian)機(ji)(ji)組制造行(xing)業(ye)中的(de)(de)(de)翹楚。
