耐腐蝕(shi)化(hua)工(gong)離心泵的種(zhong)類(lei)有很多(duo)，在(zai)使用(yong)中(zhong)可分為(wei)民用(yong)泵和(he)(he)工業泵，在(zai)輸送介質中(zhong)可分為(wei)清(qing)水泵、雜(za)質泵和(he)(he)耐腐(fu)(fu)蝕泵等。耐腐(fu)(fu)蝕化工離心泵(beng)是工(gong)業(ye)生(sheng)產中(zhong)常用(yong)(yong)的(de)化工(gong)離(li)心泵，強(qiang)耐腐蝕(shi)離(li)心泵通常采用(yong)(yong)電動(dong)機帶動(dong)泵運轉，對于強(qiang)耐腐蝕(shi)泵主要的(de)驅動(dong)設備電機，在啟(qi)(qi)動(dong)的(de)時候(hou)有(you)(you)很多種方式。其中(zhong)包括(kuo)直接啟(qi)(qi)動(dong)、自耦減壓啟(qi)(qi)動(dong)、Y-Δ 降壓啟(qi)(qi)動(dong)、軟啟(qi)(qi)動(dong)器啟(qi)(qi)動(dong)、變頻器啟(qi)(qi)動(dong)等(deng)等(deng)方式。那么接下來跟著(zhu)杰凱小編一起了解下離(li)心泵的(de)電機啟(qi)(qi)動(dong)有(you)(you)什么要求(qiu)以及如(ru)何啟(qi)(qi)動(dong)吧！
一.耐腐蝕泵電(dian)機(ji)啟動要求
1.有(you)足夠的啟動(dong)(dong)轉矩，保(bao)證泵能正(zheng)常啟動(dong)(dong)。
2.在(zai)滿足啟動(dong)(dong)轉矩的要求下，啟動(dong)(dong)電流(liu)越(yue)小越(yue)好。要求啟動(dong)(dong)平穩，減小對泵機械結構的沖擊。
3.啟(qi)動電流對(dui)電網(wang)沖擊(ji)越小越好(hao)，啟(qi)動設備(bei)安全可靠(kao)，操(cao)作方(fang)便。
4.啟動(dong)過程中損(sun)耗越小越好。
二.化工離心泵自(zi)耦減壓啟動(dong)
自(zi)耦(ou)減壓啟(qi)(qi)(qi)(qi)動(dong)(dong)是籠型(xing)感應電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)的(de)(de)(de)啟(qi)(qi)(qi)(qi)動(dong)(dong)方(fang)法之(zhi)一。其具有電(dian)(dian)(dian)路結構緊湊，不(bu)受(shou)電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)繞組(zu)接線方(fang)式的(de)(de)(de)限制(zhi)。還可(ke)(ke)按(an)允許的(de)(de)(de)啟(qi)(qi)(qi)(qi)動(dong)(dong)電(dian)(dian)(dian)流和所(suo)需要(yao)(yao)的(de)(de)(de)啟(qi)(qi)(qi)(qi)動(dong)(dong)轉(zhuan)矩選用不(bu)同的(de)(de)(de)變(bian)壓器電(dian)(dian)(dian)壓抽頭(tou)，故適用于(yu)容(rong)量較大的(de)(de)(de)電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)。自(zi)耦(ou)變(bian)壓器的(de)(de)(de)次級(ji)設有多個抽頭(tou)，可(ke)(ke)輸出不(bu)同的(de)(de)(de)電(dian)(dian)(dian)壓。一般自(zi)耦(ou)變(bian)壓器次級(ji)電(dian)(dian)(dian)壓是初級(ji)的(de)(de)(de)40%、65%、80%等(deng)，可(ke)(ke)根據啟(qi)(qi)(qi)(qi)動(dong)(dong)轉(zhuan)矩需要(yao)(yao)選用。這種(zhong)啟(qi)(qi)(qi)(qi)動(dong)(dong)方(fang)式是在(zai)定子(zi)串(chuan)電(dian)(dian)(dian)阻或電(dian)(dian)(dian)抗器的(de)(de)(de)降壓啟(qi)(qi)(qi)(qi)動(dong)(dong)方(fang)式，此方(fang)式只適用于(yu)空載或輕載啟(qi)(qi)(qi)(qi)動(dong)(dong)的(de)(de)(de)場合。
