耐(nai)腐蝕化工離心泵的種類(lei)有(you)很(hen)多，在(zai)使(shi)用中(zhong)可分(fen)為民(min)用泵(beng)和工業泵(beng)，在(zai)輸送(song)介質中(zhong)可分(fen)為清(qing)水泵(beng)、雜質泵(beng)和耐(nai)腐蝕泵(beng)等(deng)。耐(nai)腐蝕化工離心(xin)泵(beng)是(shi)工(gong)業生產中常(chang)用(yong)的化工(gong)離(li)心泵(beng)，強耐(nai)腐蝕離(li)心泵(beng)通常(chang)采用(yong)電動(dong)(dong)(dong)(dong)(dong)機(ji)帶動(dong)(dong)(dong)(dong)(dong)泵(beng)運(yun)轉(zhuan)，對于強耐(nai)腐蝕泵(beng)主(zhu)要的驅動(dong)(dong)(dong)(dong)(dong)設備電機(ji)，在啟(qi)動(dong)(dong)(dong)(dong)(dong)的時候有很多種(zhong)方式(shi)。其中包括直接(jie)啟(qi)動(dong)(dong)(dong)(dong)(dong)、自耦減壓啟(qi)動(dong)(dong)(dong)(dong)(dong)、Y-Δ 降(jiang)壓啟(qi)動(dong)(dong)(dong)(dong)(dong)、軟(ruan)啟(qi)動(dong)(dong)(dong)(dong)(dong)器(qi)啟(qi)動(dong)(dong)(dong)(dong)(dong)、變頻器(qi)啟(qi)動(dong)(dong)(dong)(dong)(dong)等等方式(shi)。那么(me)接(jie)下來跟著杰凱小編一(yi)起了解下離(li)心泵(beng)的電機(ji)啟(qi)動(dong)(dong)(dong)(dong)(dong)有什(shen)么(me)要求以及如何(he)啟(qi)動(dong)(dong)(dong)(dong)(dong)吧！
一.耐腐(fu)蝕泵電機啟動要求
1.有足(zu)夠的啟動轉矩，保證(zheng)泵能正常啟動。
2.在(zai)滿足(zu)啟(qi)動轉矩的(de)要求下，啟(qi)動電流越小越好。要求啟(qi)動平(ping)穩，減小對泵機械結構的(de)沖(chong)擊。
3.啟動電流對電網沖(chong)擊(ji)越小越好(hao)，啟動設備安全可靠，操作方便。
4.啟動過程(cheng)中損(sun)耗越小越好。
二.化工離心(xin)泵自(zi)耦減壓啟動(dong)
自(zi)耦減壓(ya)(ya)啟(qi)動(dong)是籠型(xing)感應電(dian)(dian)動(dong)機的(de)(de)啟(qi)動(dong)方(fang)法之一。其具(ju)有電(dian)(dian)路結構緊湊，不受電(dian)(dian)動(dong)機繞組接線方(fang)式(shi)的(de)(de)限制。還可(ke)按允(yun)許(xu)的(de)(de)啟(qi)動(dong)電(dian)(dian)流(liu)和所需要(yao)的(de)(de)啟(qi)動(dong)轉矩(ju)選用不同的(de)(de)變(bian)(bian)壓(ya)(ya)器電(dian)(dian)壓(ya)(ya)抽(chou)(chou)頭，故(gu)適用于(yu)容量較(jiao)大的(de)(de)電(dian)(dian)動(dong)機。自(zi)耦變(bian)(bian)壓(ya)(ya)器的(de)(de)次(ci)級設有多個抽(chou)(chou)頭，可(ke)輸出不同的(de)(de)電(dian)(dian)壓(ya)(ya)。一般自(zi)耦變(bian)(bian)壓(ya)(ya)器次(ci)級電(dian)(dian)壓(ya)(ya)是初(chu)級的(de)(de)40%、65%、80%等，可(ke)根(gen)據(ju)啟(qi)動(dong)轉矩(ju)需要(yao)選用。這種啟(qi)動(dong)方(fang)式(shi)是在定子串電(dian)(dian)阻或(huo)(huo)電(dian)(dian)抗器的(de)(de)降壓(ya)(ya)啟(qi)動(dong)方(fang)式(shi)，此方(fang)式(shi)只(zhi)適用于(yu)空(kong)載(zai)或(huo)(huo)輕載(zai)啟(qi)動(dong)的(de)(de)場(chang)合。
