潛(qian)水排污泵是(shi)一(yi)種(zhong)泵與(yu)電機連(lian)體,并(bing)同時潛(qian)入液下工作(zuo)的泵類(lei)產品(pin),與(yu)一(yi)般(ban)臥式(shi)泵或立式(shi)污水泵相比,潛(qian)水排污泵明顯具有以下幾個方面的優點(dian)：

1.結(jie)構(gou)緊(jin)湊、占地面積小。潛水(shui)排污(wu)泵由于潛入液下工作,因此可直接安裝(zhuang)(zhuang)于污(wu)水(shui)池(chi)內,無需建(jian)造(zao)專門(men)的泵房用來安裝(zhuang)(zhuang)泵及(ji)機,可以節省(sheng)大量的土地及(ji)基建(jian)費用。

2.安(an)裝維(wei)修方便。小型的潛水排污泵可(ke)以(yi)自(zi)由(you)安(an)裝,大型的潛水排污泵一般都配有自(zi)動(dong)藕合裝置(zhi)可(ke)以(yi)進(jin)行自(zi)動(dong)安(an)裝,安(an)裝及維(wei)修相當方便。

3.連續運轉(zhuan)時(shi)間長(chang)。潛水排污泵由于(yu)泵和(he)電機同軸(zhou)(zhou),軸(zhou)(zhou)短,轉(zhuan)動部件重(zhong)量輕,因此軸(zhou)(zhou)承上(shang)承受的(de)載荷(徑向(xiang))相(xiang)對(dui)較小(xiao),壽命比一般泵要長(chang)得(de)多。

4.不存在汽蝕破壞及灌引水(shui)等問題。特別是后(hou)一點給操(cao)作人員帶來了很大的方(fang)便(bian)。

5.振(zhen)動(dong)噪聲小,電機(ji)溫升低,對(dui)環境無污(wu)染。

正是由于上述優(you)點(dian),潛水排污泵已越(yue)(yue)來越(yue)(yue)受(shou)到人們(men)的(de)重(zhong)視,使用的(de)范圍也越(yue)(yue)來越(yue)(yue)廣,由原來的(de)單純地(di)用來輸送(song)清水到現在(zai)的(de)可以輸送(song)各種生活(huo)污水、工(gong)(gong)業廢水、建筑(zhu)(zhu)工(gong)(gong)地(di)排水、液狀飼料(liao)等(deng)等(deng)。在(zai)市(shi)政工(gong)(gong)程、工(gong)(gong)業、醫院、建筑(zhu)(zhu)、飯店、水利建設(she)等(deng)各行各業中起著十分重(zhong)要的(de)作(zuo)用。

但是(shi)(shi)任何事(shi)物都是(shi)(shi)一(yi)(yi)(yi)分為二的(de),對于潛水(shui)(shui)排污(wu)泵(beng)來說(shuo)最(zui)關鍵(jian)的(de)問題是(shi)(shi)可靠性問題,因為潛水(shui)(shui)排污(wu)泵(beng)的(de)使(shi)(shi)用場合是(shi)(shi)在(zai)液下;輸送(song)的(de)介質是(shi)(shi)一(yi)(yi)(yi)些含(han)有固體物料的(de)混合液體;泵(beng)與(yu)電機(ji)靠得(de)很近(jin);泵(beng)為立式布(bu)(bu)置,轉動部件重量與(yu)葉輪承(cheng)受水(shui)(shui)壓(ya)力同(tong)向。這些問題都使(shi)(shi)得(de)潛水(shui)(shui)排污(wu)泵(beng)在(zai)密封、電機(ji)承(cheng)載(zai)能力、軸承(cheng)布(bu)(bu)置及選用等方面(mian)的(de)要求(qiu)比一(yi)(yi)(yi)般的(de)污(wu)水(shui)(shui)泵(beng)要高。

建(jian)筑物內使用(yong)的(de)排(pai)水(shui)泵(beng)(beng)(beng)有潛水(shui)排(pai)污(wu)(wu)(wu)泵(beng)(beng)(beng)、液下式(shi)(shi)(shi)(shi)無堵塞(sai)排(pai)污(wu)(wu)(wu)泵(beng)(beng)(beng)、立式(shi)(shi)(shi)(shi)污(wu)(wu)(wu)水(shui)泵(beng)(beng)(beng)和(he)臥(wo)式(shi)(shi)(shi)(shi)污(wu)(wu)(wu)水(shui)泵(beng)(beng)(beng)等。由于建(jian)筑物內一般場(chang)地(di)較小，排(pai)水(shui)量不大(da)，排(pai)水(shui)泵(beng)(beng)(beng)可(ke)優先采(cai)用(yong)潛水(shui)排(pai)污(wu)(wu)(wu)泵(beng)(beng)(beng)和(he)液下式(shi)(shi)(shi)(shi)無堵塞(sai)排(pai)污(wu)(wu)(wu)泵(beng)(beng)(beng)，其中液下排(pai)污(wu)(wu)(wu)泵(beng)(beng)(beng)一般在重要(yao)場(chang)所使用(yong)；立式(shi)(shi)(shi)(shi)污(wu)(wu)(wu)水(shui)泵(beng)(beng)(beng)和(he)臥(wo)式(shi)(shi)(shi)(shi)污(wu)(wu)(wu)水(shui)泵(beng)(beng)(beng)要(yao)求設置隔震基礎(chu)、自灌式(shi)(shi)(shi)(shi)吸水(shui)、并占用(yong)一定的(de)場(chang)地(di)，故在建(jian)筑中較少使用(yong)。
