耐腐蝕離心泵是工業化生產中常見(jian)的(de)化工離心泵，化工(gong)耐腐蝕離心泵通常采用電(dian)(dian)動機(ji)促(cu)進泵運作，電(dian)(dian)機(ji)是耐(nai)腐蝕泵的關鍵控制設備。在啟(qi)動(dong)(dong)(dong)的當時有(you)很多種方法，包含立即啟(qi)動(dong)(dong)(dong)、軟啟(qi)動(dong)(dong)(dong)器啟(qi)動(dong)(dong)(dong)、定(ding)頻(pin)啟(qi)動(dong)(dong)(dong)等方法，那么他們之間有(you)什么不同的效果呢？
一. 耐(nai)腐(fu)蝕離心泵(beng)啟動電機的規定
1.有任何啟動扭矩(ju)來確保(bao)泵可以(yi)無問題地啟動。
2.起動交流功(gong)率越低，在起動轉(zhuan)矩的調節下越好。調節穩定啟動，減少對離心泵泵機械系統的影響。
3.啟(qi)動交流電對電網的影(ying)響越(yue)小越(yue)好。起動裝置可靠，使用方便。
4.啟動過程(cheng)中浪費(fei)越少(shao)越好。
立(li)即起動也(ye)是(shi)將電(dian)(dian)(dian)動機的(de)定子繞阻(zu)根據旋(xuan)鈕或中(zhong)間繼電(dian)(dian)(dian)器(qi)立(li)即連(lian)接電(dian)(dian)(dian)原，在電(dian)(dian)(dian)動機額定電(dian)(dian)(dian)流(liu)下起動。在電(dian)(dian)(dian)力網容(rong)積和負荷兩層面都容(rong)許全壓立(li)即起動的(de)狀(zhuang)況(kuang)下，能(neng)夠考量選用全壓立(li)即起動。優勢是(shi)控制操縱(zong)便捷(jie)，保(bao)護(hu)簡易，并(bing)且較(jiao)為第三(san)產業。主要用于小功率電(dian)(dian)(dian)機的(de)起動，從節省電(dian)(dian)(dian)磁能(neng)的(de)視角考量，超過11kw的電動機不適(shi)合(he)用(yong)此方(fang)式。
二.軟(ruan)啟動(dong)(dong)在控(kong)制回路中選(xuan)(xuan)用(yong)(yong)(yong)軟(ruan)啟動(dong)(dong)器。關(guan)鍵組成是串(chuan)接與電(dian)(dian)(dian)原與電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)中間的(de)三反過來串(chuan)聯閘(zha)(zha)管(guan)(guan)以(yi)及電(dian)(dian)(dian)子控(kong)制回路。選(xuan)(xuan)用(yong)(yong)(yong)軟(ruan)啟動(dong)(dong)時(shi)，晶閘(zha)(zha)管(guan)(guan)的(de)輸出(chu)電(dian)(dian)(dian)流慢慢提升，電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)慢慢加快，當晶閘(zha)(zha)管(guan)(guan)徹底(di)導通，電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)及進(jin)到額定(ding)工作態(tai)度(du)。軟(ruan)啟動(dong)(dong)具(ju)備起動(dong)(dong)穩定(ding)、起動(dong)(dong)交流電(dian)(dian)(dian)低的(de)特性。它是運用(yong)(yong)(yong)了(le)晶閘(zha)(zha)管(guan)(guan)的(de)移相調壓機(ji)(ji)理(li)來保持電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)的(de)調壓起動(dong)(dong)，主要用(yong)(yong)(yong)于電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)的(de)起動(dong)(dong)操縱，起動(dong)(dong)好用(yong)(yong)(yong)但利潤較高(gao)。因應(ying)用(yong)(yong)(yong)了(le)晶閘(zha)(zha)管(guan)(guan)元器件，晶閘(zha)(zha)管(guan)(guan)工做時(shi)諧波干撓很大，對電(dian)(dian)(dian)力網有必須的(de)危(wei)害。
