耐腐蝕化工離心泵的種類有很多，在使用(yong)中可分(fen)為民用(yong)泵(beng)(beng)和工業泵(beng)(beng)，在輸送(song)介(jie)質中可分(fen)為清水泵(beng)(beng)、雜質泵(beng)(beng)和耐(nai)(nai)腐蝕(shi)泵(beng)(beng)等。耐(nai)(nai)腐蝕(shi)化工離心(xin)泵(beng)是工(gong)業(ye)生產(chan)中常用的(de)化工(gong)離(li)心(xin)泵，強耐腐(fu)蝕(shi)離(li)心(xin)泵通(tong)常采用電動(dong)(dong)(dong)(dong)機帶動(dong)(dong)(dong)(dong)泵運(yun)轉，對于強耐腐(fu)蝕(shi)泵主要(yao)的(de)驅動(dong)(dong)(dong)(dong)設備電機，在(zai)啟(qi)動(dong)(dong)(dong)(dong)的(de)時候有很多種方式(shi)。其中包括直(zhi)接啟(qi)動(dong)(dong)(dong)(dong)、自耦減壓啟(qi)動(dong)(dong)(dong)(dong)、Y-Δ 降壓啟(qi)動(dong)(dong)(dong)(dong)、軟啟(qi)動(dong)(dong)(dong)(dong)器啟(qi)動(dong)(dong)(dong)(dong)、變頻器啟(qi)動(dong)(dong)(dong)(dong)等(deng)等(deng)方式(shi)。那么接下來(lai)跟著杰凱(kai)小編一起了解下離(li)心(xin)泵的(de)電機啟(qi)動(dong)(dong)(dong)(dong)有什(shen)么要(yao)求以及(ji)如何啟(qi)動(dong)(dong)(dong)(dong)吧！
一.耐腐(fu)蝕(shi)泵電機啟動要求
1.有足夠的啟動轉矩，保證泵能正常啟動。
2.在滿足啟動(dong)轉(zhuan)矩的要求(qiu)下，啟動(dong)電流越(yue)小越(yue)好。要求(qiu)啟動(dong)平穩，減小對泵機(ji)械(xie)結構(gou)的沖擊。
3.啟動(dong)電(dian)(dian)流對電(dian)(dian)網沖擊越小越好(hao)，啟動(dong)設備(bei)安全可靠，操(cao)作方便。
4.啟動過(guo)程中損耗(hao)越小越好。
二.化工離(li)心泵自耦減壓啟(qi)動
自耦減壓(ya)(ya)(ya)(ya)啟(qi)(qi)動(dong)(dong)(dong)(dong)是籠型感應(ying)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機的(de)(de)啟(qi)(qi)動(dong)(dong)(dong)(dong)方(fang)法之一(yi)(yi)。其(qi)具(ju)有(you)電(dian)(dian)(dian)路結構緊湊，不(bu)(bu)受電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機繞組接線方(fang)式(shi)的(de)(de)限(xian)制。還可(ke)按允許的(de)(de)啟(qi)(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)流和所需要的(de)(de)啟(qi)(qi)動(dong)(dong)(dong)(dong)轉矩(ju)選(xuan)用不(bu)(bu)同(tong)的(de)(de)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)抽頭，故適(shi)用于容量較(jiao)大的(de)(de)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機。自耦變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)的(de)(de)次級(ji)(ji)設(she)有(you)多個抽頭，可(ke)輸出不(bu)(bu)同(tong)的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)。一(yi)(yi)般自耦變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)次級(ji)(ji)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)是初級(ji)(ji)的(de)(de)40%、65%、80%等，可(ke)根據啟(qi)(qi)動(dong)(dong)(dong)(dong)轉矩(ju)需要選(xuan)用。這(zhe)種啟(qi)(qi)動(dong)(dong)(dong)(dong)方(fang)式(shi)是在定子串(chuan)電(dian)(dian)(dian)阻(zu)或(huo)電(dian)(dian)(dian)抗器(qi)的(de)(de)降壓(ya)(ya)(ya)(ya)啟(qi)(qi)動(dong)(dong)(dong)(dong)方(fang)式(shi)，此(ci)方(fang)式(shi)只適(shi)用于空載(zai)或(huo)輕(qing)載(zai)啟(qi)(qi)動(dong)(dong)(dong)(dong)的(de)(de)場合。
