直流水(shui)(shui)泵(beng)(beng)的(de)(de)工(gong)(gong)作(zuo)(zuo)原理主要基于(yu)(yu)電(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)將電(dian)(dian)(dian)能(neng)轉(zhuan)(zhuan)換為機(ji)(ji)(ji)(ji)械能(neng)，進而通(tong)過(guo)機(ji)(ji)(ji)(ji)械傳動將水(shui)(shui)推向(xiang)(xiang)出水(shui)(shui)口(kou)，實現水(shui)(shui)的(de)(de)輸送。具體來(lai)說(shuo)，當(dang)直流電(dian)(dian)(dian)源(yuan)接通(tong)后(hou)，電(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)內部的(de)(de)轉(zhuan)(zhuan)子開(kai)始旋(xuan)轉(zhuan)(zhuan)，旋(xuan)轉(zhuan)(zhuan)磁(ci)場作(zuo)(zuo)用下的(de)(de)力使(shi)得轉(zhuan)(zhuan)子開(kai)始旋(xuan)轉(zhuan)(zhuan)并帶動葉(xie)輪一起旋(xuan)轉(zhuan)(zhuan)。葉(xie)輪旋(xuan)轉(zhuan)(zhuan)時就能(neng)將水(shui)(shui)帶出并推向(xiang)(xiang)出水(shui)(shui)口(kou)。電(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)產(chan)生電(dian)(dian)(dian)能(neng)，驅動葉(xie)輪旋(xuan)轉(zhuan)(zhuan)，在離心(xin)力作(zuo)(zuo)用下，水(shui)(shui)由進口(kou)進入水(shui)(shui)泵(beng)(beng)體內，經過(guo)葉(xie)輪的(de)(de)作(zuo)(zuo)用，被加速，然(ran)后(hou)在出口(kou)處排出。密封裝置(zhi)用于(yu)(yu)保護水(shui)(shui)泵(beng)(beng)不進水(shui)(shui)或漏水(shui)(shui)。此外(wai)，直流無(wu)刷水(shui)(shui)泵(beng)(beng)是通(tong)過(guo)電(dian)(dian)(dian)磁(ci)感(gan)應原理工(gong)(gong)作(zuo)(zuo)的(de)(de)。其主要由轉(zhuan)(zhuan)子、定子、電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)控制(zhi)電(dian)(dian)(dian)路等組成(cheng)。電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)控制(zhi)電(dian)(dian)(dian)路通(tong)過(guo)控制(zhi)電(dian)(dian)(dian)流和電(dian)(dian)(dian)壓的(de)(de)大(da)小和方向(xiang)(xiang)，使(shi)轉(zhuan)(zhuan)子在磁(ci)場的(de)(de)作(zuo)(zuo)用下旋(xuan)轉(zhuan)(zhuan)，從(cong)而驅動水(shui)(shui)泵(beng)(beng)工(gong)(gong)作(zuo)(zuo)。
