耐腐(fu)蝕化(hua)工離心泵的(de)種類有很多，在(zai)使用中可分(fen)為(wei)民用泵(beng)和工(gong)業泵(beng)，在(zai)輸送(song)介(jie)質中可分(fen)為(wei)清水泵(beng)、雜質泵(beng)和耐(nai)腐(fu)蝕泵(beng)等。耐(nai)腐(fu)蝕化工(gong)離(li)心泵是工業(ye)生(sheng)產中(zhong)(zhong)常用的(de)化工離(li)(li)心(xin)泵(beng)(beng)，強耐腐蝕離(li)(li)心(xin)泵(beng)(beng)通常采用電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)帶動(dong)(dong)(dong)(dong)(dong)泵(beng)(beng)運轉，對于強耐腐蝕泵(beng)(beng)主要(yao)的(de)驅動(dong)(dong)(dong)(dong)(dong)設備電(dian)(dian)機(ji)，在啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)的(de)時候(hou)有很多種方式(shi)。其(qi)中(zhong)(zhong)包括直接啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、自耦減壓啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、Y-Δ 降(jiang)壓啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、軟啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)器(qi)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、變頻(pin)器(qi)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)等等方式(shi)。那么接下來跟(gen)著杰凱小編一起了解下離(li)(li)心(xin)泵(beng)(beng)的(de)電(dian)(dian)機(ji)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)有什么要(yao)求以及如何啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)吧！
一(yi).耐腐蝕泵電機啟動(dong)要求
1.有足(zu)夠的啟(qi)動(dong)轉矩，保證泵能正常啟(qi)動(dong)。
2.在(zai)滿(man)足啟(qi)(qi)動轉矩的要求下，啟(qi)(qi)動電流越小(xiao)越好。要求啟(qi)(qi)動平穩，減小(xiao)對泵機械結構的沖擊。
3.啟(qi)動(dong)電流對(dui)電網(wang)沖(chong)擊(ji)越小越好(hao)，啟(qi)動(dong)設備安全可靠，操作方便。
4.啟(qi)動過程中損耗越小越好。
二.化工離心(xin)泵自耦減壓啟動
自耦減壓啟動(dong)(dong)是(shi)籠型感應電(dian)(dian)(dian)動(dong)(dong)機(ji)的(de)(de)(de)啟動(dong)(dong)方法之一。其具(ju)有電(dian)(dian)(dian)路(lu)結構緊湊(cou)，不受(shou)電(dian)(dian)(dian)動(dong)(dong)機(ji)繞(rao)組接線方式(shi)的(de)(de)(de)限制。還可按允許的(de)(de)(de)啟動(dong)(dong)電(dian)(dian)(dian)流和所需(xu)(xu)要的(de)(de)(de)啟動(dong)(dong)轉矩(ju)選(xuan)用不同的(de)(de)(de)變壓器(qi)(qi)電(dian)(dian)(dian)壓抽(chou)頭(tou)，故適用于(yu)容(rong)量較(jiao)大的(de)(de)(de)電(dian)(dian)(dian)動(dong)(dong)機(ji)。自耦變壓器(qi)(qi)的(de)(de)(de)次級(ji)(ji)設有多個抽(chou)頭(tou)，可輸出不同的(de)(de)(de)電(dian)(dian)(dian)壓。一般(ban)自耦變壓器(qi)(qi)次級(ji)(ji)電(dian)(dian)(dian)壓是(shi)初級(ji)(ji)的(de)(de)(de)40%、65%、80%等，可根據啟動(dong)(dong)轉矩(ju)需(xu)(xu)要選(xuan)用。這種啟動(dong)(dong)方式(shi)是(shi)在定子(zi)串(chuan)電(dian)(dian)(dian)阻或電(dian)(dian)(dian)抗器(qi)(qi)的(de)(de)(de)降壓啟動(dong)(dong)方式(shi)，此方式(shi)只適用于(yu)空載或輕載啟動(dong)(dong)的(de)(de)(de)場合(he)。
