如何辨別偽劣真假柴油發電機組，謹防上當受騙！

柴油機發電機

柴(chai)油機(ji)發(fa)電(dian)機(ji)關鍵分成幾大一部(bu)分：柴(chai)油發(fa)動機(ji)、發(fa)電(dian)機(ji)、自動控(kong)制系統、附(fu)設件。

一、柴油發動機

柴(chai)油發(fa)動機是全部發(fa)電機組的驅動力輸(shu)出一部分，占據(ju)柴(chai)油機發(fa)電機成(cheng)本費(fei)的75%，是某些(xie)欠佳生產廠家最愛(ai)弄虛做假(jia)的階(jie)段。一切柴(chai)油機發(fa)電機生產廠家的柴(chai)油發(fa)動機全是外購的。

2、翻新老機

各知名品牌(pai)常有翻(fan)新老機(ji)，一(yi)樣并不(bu)是(shi)專(zhuan)業技術(shu)人員沒(mei)辦法辨別，方(fang)法同(tong)上。

但一些列外，本質(zhi)無需評(ping)定。比如(ru)廣東(dong)省一些生(sheng)產(chan)廠(chang)家從印尼進(jin)口康明斯(si)的二手機(ji)翻修，由(you)于印尼也是(shi)玉柴(chai)發動(dong)機(ji)的加工廠(chang)，這種欠佳生(sheng)產(chan)廠(chang)家就稱為是(shi)進(jin)口康明斯(si)柴(chai)油機(ji)，還可出示中(zhong)國海關(guan)證(zheng)明材料。

事實上玉柴發(fa)動機(ji)(ji)(ji)由于在(zai)我國(guo)現(xian)有(you)2個合資廠：襄樊東風康(kang)明(ming)斯、康(kang)明(ming)斯柴油機(ji)(ji)(ji)，因此是有(you)貿(mao)易(yi)保護(hu)協議書(shu)的。玉柴發(fa)動機(ji)(ji)(ji)在(zai)世界各國(guo)的加工(gong)廠都(dou)劃分有(you)市場(chang)銷售地(di)區(qu)，禁止(zhi)矛盾，全部稱為進口康(kang)明(ming)斯發(fa)動機(ji)(ji)(ji)并不是是新手機(ji)(ji)(ji)，否則走私(si)(si)貨，但走私(si)(si)貨也不容易(yi)有(you)中國(guo)海(hai)關證明(ming)材料了。

、小馬拉大貨車

搞混(hun)KVA和千(qian)瓦(wa)的關聯。把KVA當(dang)做千(qian)瓦(wa)夸大其詞輸(shu)出功(gong)(gong)率(lv)，賣顧客。事實上KVA是視在功(gong)(gong)率(lv)，千(qian)瓦(wa)是合理輸(shu)出功(gong)(gong)率(lv)，她們之(zhi)間的關系為(wei)1KVA=0.7千(qian)瓦(wa)。進(jin)口(kou)發電機組通(tong)常用KVA表達功(gong)(gong)率(lv)單位，而中國用電量機器設(she)備通(tong)常都用千(qian)瓦(wa)表達，因此(ci)結轉(zhuan)輸(shu)出功(gong)(gong)率(lv)時要把KVA打8折計算成千(qian)瓦(wa)。

不(bu)講長行(xing)(xing)（額定值）輸出(chu)(chu)功(gong)率(lv)和(he)儲(chu)備(bei)(bei)(bei)輸出(chu)(chu)功(gong)率(lv)的關聯，僅說1個“輸出(chu)(chu)功(gong)率(lv)”，把儲(chu)備(bei)(bei)(bei)輸出(chu)(chu)功(gong)率(lv)作(zuo)為長行(xing)(xing)輸出(chu)(chu)功(gong)率(lv)賣顧客。事(shi)實上，儲(chu)備(bei)(bei)(bei)輸出(chu)(chu)功(gong)率(lv)=1.2ｘ長行(xing)(xing)輸出(chu)(chu)功(gong)率(lv)。并且，儲(chu)備(bei)(bei)(bei)輸出(chu)(chu)功(gong)率(lv)只(zhi)有在13鐘頭持續運作(zuo)中應用1鐘頭。

柴油發動(dong)(dong)(dong)機輸出功(gong)率(lv)與發電(dian)(dian)機的(de)輸出功(gong)率(lv)配備(bei)成(cheng)相同大，而求控制(zhi)成(cheng)本。事實上，業(ye)界通常要求柴油發動(dong)(dong)(dong)機輸出功(gong)率(lv)≥發電(dian)(dian)機功(gong)率(lv)12%，由于有機械設備(bei)耗損。更(geng)加(jia)極端(duan)的(de)，也有的(de)把柴油發動(dong)(dong)(dong)機大馬力作為KW誤報給客戶，及(ji)用低于發電(dian)(dian)機功(gong)率(lv)的(de)柴油發動(dong)(dong)(dong)機來配備(bei)發電(dian)(dian)機組，別(bie)名(ming)：小馬拉大貨車，以致發電(dian)(dian)機組使用壽命減少，檢修經(jing)常，服務費持續(xu)上升。

辨別(bie)時只需問情柴油(you)發(fa)動機的(de)(de)常(chang)(chang)見(jian)和(he)應(ying)(ying)急(ji)輸(shu)出(chu)功率，這(zhe)2個(ge)統計數據發(fa)電(dian)機組廠家通常(chang)(chang)很怕做假(jia)，由于柴油(you)機廠家常(chang)(chang)有(you)發(fa)布。只需柴油(you)發(fa)動機的(de)(de)常(chang)(chang)見(jian)和(he)應(ying)(ying)急(ji)輸(shu)出(chu)功率比柴油(you)發(fa)電(dian)機的(de)(de)常(chang)(chang)見(jian)和(he)應(ying)(ying)急(ji)輸(shu)出(chu)功率各大12%只能。

5、換牌，以小充大

將(jiang)功(gong)率柴(chai)油(you)發(fa)(fa)動(dong)(dong)機的(de)(de)銘牌轉到(dao)小(xiao)1號的(de)(de)柴(chai)油(you)發(fa)(fa)動(dong)(dong)機上，以小(xiao)充大(da)，大(da)到(dao)控制成本(ben)的(de)(de)目地。方式同(tong)(tong)柴(chai)油(you)發(fa)(fa)動(dong)(dong)機第(di)1條，合同(tong)(tong)書中注明：賣家(jia)(jia)確保(bao)柴(chai)油(you)發(fa)(fa)動(dong)(dong)機是某(mou)(mou)某(mou)(mou)某(mou)(mou)廠原(yuan)裝全新升級真品發(fa)(fa)電廠用(yong)柴(chai)油(you)發(fa)(fa)動(dong)(dong)機且型號規格(ge)無偽造(zao)，不然假一罰十，以某(mou)(mou)某(mou)(mou)某(mou)(mou)廠某(mou)(mou)某(mou)(mou)某(mou)(mou)地售(shou)后維修服務站評(ping)定結果(guo)起算(suan)，由(you)買家(jia)(jia)聯絡評(ping)定事項，花(hua)費由(you)賣家(jia)(jia)擔負。要(yao)寫清純正(zheng)生(sheng)產廠家(jia)(jia)全名，并堅持不懈(xie)做評(ping)定。

6、發(fa)電廠(chang)用柴(chai)油發(fa)動(dong)機

柴(chai)(chai)油(you)(you)機(ji)(ji)(ji)發(fa)電(dian)機(ji)(ji)(ji)配備(bei)的柴(chai)(chai)油(you)(you)發(fa)動機(ji)(ji)(ji)都應當是(shi)發(fa)電(dian)廠專(zhuan)用(yong)(yong)型用(yong)(yong)柴(chai)(chai)油(you)(you)發(fa)動機(ji)(ji)(ji)，其(qi)轉(zhuan)速比(bi)都應當平穩在3000轉(zhuan)/分(fen)。而工程(cheng)用(yong)(yong)柴(chai)(chai)油(you)(you)發(fa)動機(ji)(ji)(ji)、船用(yong)(yong)柴(chai)(chai)油(you)(you)機(ji)(ji)(ji)等(deng)非發(fa)電(dian)廠專(zhuan)用(yong)(yong)型柴(chai)(chai)油(you)(you)發(fa)動機(ji)(ji)(ji)轉(zhuan)速比(bi)范疇(chou)大(da)，改為固(gu)定不動3000轉(zhuan)后轉(zhuan)速比(bi)是(shi)比(bi)不上發(fa)電(dian)廠專(zhuan)用(yong)(yong)型柴(chai)(chai)油(you)(you)發(fa)動機(ji)(ji)(ji)平穩的。

二、發電機

1、以相仿企業名混淆(xiao)視聽

發(fa)電機(ji)技術性門坎(kan)不高，品質徹(che)底在于用料(liao)是不是精美。

2、電機(ji)定子(zi)鐵芯硅鋼片

電(dian)(dian)機定(ding)子鐵芯是由硅鋼片沖壓模具(ju)成(cheng)型后一塊(kuai)塊(kuai)累加(jia)電(dian)(dian)焊焊接而成(cheng)，硅鋼片的(de)優劣(lie)明(ming)顯提高電(dian)(dian)機定(ding)子電(dian)(dian)磁(ci)場環流的(de)尺(chi)寸。

3、電(dian)機定子(zi)電(dian)磁線圈的材料

電(dian)(dian)機定子電(dian)(dian)磁線(xian)(xian)圈(quan)原來選(xuan)用(yong)(yong)的(de)均是全銅(tong)(tong)(tong)心(xin)線(xian)(xian)，但隨之(zhi)制線(xian)(xian)技術性(xing)的(de)提升(sheng)，出現(xian)了銅(tong)(tong)(tong)包(bao)鋁(lv)銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)纜。差別于滾鍍鋁(lv)線(xian)(xian)電(dian)(dian)纜，銅(tong)(tong)(tong)包(bao)鋁(lv)銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)纜是選(xuan)用(yong)(yong)獨特磨具在(zai)吊線(xian)(xian)成形(xing)時銅(tong)(tong)(tong)包(bao)鋁(lv)，銅(tong)(tong)(tong)層比滾鍍厚(hou)的(de)多(duo)(duo)。發電(dian)(dian)機定子電(dian)(dian)磁線(xian)(xian)圈(quan)選(xuan)用(yong)(yong)銅(tong)(tong)(tong)包(bao)鋁(lv)銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)纜在(zai)特性(xing)上并無很大差別，僅僅使用(yong)(yong)期比全銅(tong)(tong)(tong)心(xin)線(xian)(xian)電(dian)(dian)機定子電(dian)(dian)磁線(xian)(xian)圈(quan)短(duan)的(de)多(duo)(duo)。

識別(bie)方法：銅(tong)包鋁銅(tong)芯(xin)電(dian)纜和(he)滾(gun)鍍鋁線(xian)電(dian)纜由于線(xian)徑比同(tong)規(gui)格型(xing)號的銅(tong)心線(xian)粗，因此用銅(tong)包鋁銅(tong)芯(xin)電(dian)纜和(he)滾(gun)鍍鋁線(xian)電(dian)纜的電(dian)機(ji)定子(zi)只(zhi)有選用5/6節徑、47槽(cao)。而銅(tong)心線(xian)能夠做2/3節徑、76槽(cao)。開啟電(dian)動(dong)機(ji)后(hou)蓋，數(shu)一(yi)下電(dian)機(ji)定子(zi)鐵芯(xin)槽(cao)數(shu)就知(zhi)道。

4、電(dian)機定子電(dian)磁(ci)線圈(quan)的節徑、匝數(shu)

一樣(yang)是選用(yong)全銅(tong)心線(xian)，電機定子電磁(ci)線(xian)圈(quan)也可制成5/6節徑、47匝(za)數。由(you)于電磁(ci)線(xian)圈(quan)少了28匝(za)，銅(tong)心線(xian)使用(yong)量降低，成本(ben)費能(neng)夠減少12%。

2/3節(jie)徑、76匝電(dian)機(ji)定子選用的銅心線(xian)線(xian)徑細，匝數(shu)(shu)(shu)空出40%，每匝線(xian)圓圈(quan)數(shu)(shu)(shu)也較多(duo)，電(dian)流量波(bo)型平穩，不容易發燙。識別方法同上，數(shu)(shu)(shu)電(dian)機(ji)定子鐵(tie)芯槽數(shu)(shu)(shu)。

三、自動控制系統

一(yi)般基本型發電機組需人工服務倒閘，從停電了到柴油機發電機起動合閘，通常必須12至(zhi)40分鐘。

柴(chai)油機(ji)(ji)發電(dian)機(ji)(ji)機(ji)(ji)械自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)化(hua)(hua)(hua)分(fen)成全(quan)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)和自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)無(wu)人化(hua)(hua)(hua)型(xing)。全(quan)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)為(wei)柴(chai)油發電(dian)機(ji)(ji)停電(dian)了時全(quan)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)、撥(bo)電(dian)話時全(quan)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)關機(ji)(ji)，省掉了起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)關機(ji)(ji)的(de)時間(jian)，但還是必須人工服務倒閘(zha)。艾能驅動(dong)(dong)(dong)(dong)(dong)(dong)力配(pei)備的(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)無(wu)人化(hua)(hua)(hua)控制柜(ju)改裝ATS雙電(dian)源(yuan)切換(huan)開關，立(li)即自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)識別(bie)市電(dian)信號(hao)，全(quan)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)轉換(huan)，一起(qi)(qi)操縱柴(chai)油發電(dian)機(ji)(ji)全(quan)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)與關機(ji)(ji)，建立(li)了自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)無(wu)人化(hua)(hua)(hua)運作，轉換(huan)時間(jian)3-12秒可調式(shi)。

四、附設件

1、熱管散熱小水箱

熱管(guan)散(san)熱小水(shui)箱關鍵(jian)功效為(wei)(wei)以(yi)(yi)水(shui)為(wei)(wei)媒質(zhi)互換(huan)柴油(you)發動機內發熱量，超過減(jian)少心(xin)肌細胞(bao)溫(wen)度的目地(di)。小水(shui)箱由豎排序的一條根(gen)自(zi)來水(shui)管(guan)串連，空(kong)隙(xi)添充金(jin)屬(shu)材料散(san)熱器。國家(jia)標準每根(gen)自(zi)來水(shui)管(guan)的排序空(kong)隙(xi)為(wei)(wei)0.7厘(li)米(mi)，實(shi)際上絕(jue)大(da)多(duo)數柴油(you)機發電(dian)機生(sheng)產廠家(jia)如今應(ying)用的小水(shui)箱多(duo)見1厘(li)米(mi)，有的以(yi)(yi)至(zhi)于應(ying)用1.3厘(li)米(mi)空(kong)隙(xi)的。

2、汽車油箱、輸(shu)油管

裝柴(chai)油機用(yong)的，能夠隨(sui)意部位置放，較為便(bian)捷(jie)。

3、汽車底盤

汽(qi)車(che)底盤(pan)多見厚鋼(gang)板鈑(ban)金折(zhe)彎制(zhi)做(zuo)(zuo)，合適于(yu)固定不動(dong)應用。如客戶必須常(chang)常(chang)中移動(dong)柴(chai)油(you)發電機，須應用圓鋼(gang)制(zhi)做(zuo)(zuo)的汽(qi)車(che)底盤(pan)。

4、電瓶、充電電池(chi)輸(shu)電線

充(chong)電(dian)(dian)電(dian)(dian)池分成一般(ban)鉛酸電(dian)(dian)池、免維護電(dian)(dian)池。前者(zhe)(zhe)價(jia)錢是兩者(zhe)(zhe)的好幾倍，必需問情，在合同書或技術(shu)協議中標明是哪(na)種充(chong)電(dian)(dian)電(dian)(dian)池，充(chong)電(dian)(dian)電(dian)(dian)池輸電(dian)(dian)線有沒(mei)有。
