給排水管道離心泵結構

1、泵軸

泵軸的(de)作用是借聯軸器和電動機相(xiang)連接，將電動機的(de)轉距傳(chuan)(chuan)給葉輪，所以它是傳(chuan)(chuan)遞(di)機械能的(de)主(zhu)要部(bu)件。

2、軸承

是(shi)套(tao)在(zai)(zai)泵(beng)軸(zhou)(zhou)上支撐泵(beng)軸(zhou)(zhou)的(de)構件，有(you)(you)滾動(dong)軸(zhou)(zhou)承(cheng)和(he)滑動(dong)軸(zhou)(zhou)承(cheng)兩(liang)種。滾動(dong)軸(zhou)(zhou)承(cheng)使用(yong)牛油(you)作(zuo)(zuo)為潤(run)滑劑(ji)，加油(you)要(yao)(yao)適當(dang)，一般為2/3～3/4的(de)體積(ji)：太(tai)(tai)多會(hui)發(fa)(fa)熱(re)，太(tai)(tai)少又有(you)(you)響聲(sheng)并發(fa)(fa)熱(re)！滑動(dong)軸(zhou)(zhou)承(cheng)使用(yong)的(de)是(shi)透明油(you)作(zuo)(zuo)潤(run)滑劑(ji)的(de),加油(you)到油(you)位(wei)線。太(tai)(tai)多油(you)要(yao)(yao)沿(yan)泵(beng)軸(zhou)(zhou)滲出，太(tai)(tai)少軸(zhou)(zhou)承(cheng)又要(yao)(yao)過熱(re)燒壞(huai)造(zao)成事(shi)故！在(zai)(zai)水泵(beng)運行(xing)過程(cheng)中(zhong)軸(zhou)(zhou)承(cheng)的(de)溫度(du)高在(zai)(zai)85度(du)一般運行(xing)在(zai)(zai)60度(du)左右，如(ru)果高了就要(yao)(yao)查找原(yuan)因（是(shi)否(fou)有(you)(you)雜質，油(you)質是(shi)否(fou)發(fa)(fa)黑，是(shi)否(fou)進水）并及時(shi)處理！

3、密封環

又稱減(jian)漏環。葉輪(lun)進口與泵(beng)殼間(jian)(jian)的(de)間(jian)(jian)隙(xi)過(guo)大會造成(cheng)泵(beng)內(nei)(nei)高(gao)壓(ya)區(qu)(qu)的(de)水(shui)經此間(jian)(jian)隙(xi)流向(xiang)低(di)壓(ya)區(qu)(qu)，影響泵(beng)的(de)出水(shui)量，效率(lv)降低(di)！間(jian)(jian)隙(xi)過(guo)小會造成(cheng)葉輪(lun)與泵(beng)殼摩擦(ca)產生(sheng)磨損。為了增加回流阻(zu)力(li)減(jian)少內(nei)(nei)漏，延緩葉輪(lun)和(he)泵(beng)殼的(de)所使用壽命，在泵(beng)殼內(nei)(nei)緣和(he)葉輪(lun)外(wai)援結合(he)處(chu)裝有密(mi)封(feng)環，密(mi)封(feng)的(de)間(jian)(jian)隙(xi)保持(chi)在0.25～1.10mm之間(jian)(jian)為宜。

4、填料函

給排水管道離心泵主(zhu)要由填(tian)料(liao)(liao)(liao)，水(shui)(shui)(shui)封(feng)(feng)(feng)環，填(tian)料(liao)(liao)(liao)筒(tong)，填(tian)料(liao)(liao)(liao)壓蓋(gai)，水(shui)(shui)(shui)封(feng)(feng)(feng)管組成。填(tian)料(liao)(liao)(liao)函的作(zuo)用(yong)主(zhu)要是(shi)為了封(feng)(feng)(feng)閉泵(beng)(beng)(beng)(beng)殼與泵(beng)(beng)(beng)(beng)軸之間(jian)的空隙，不(bu)讓(rang)(rang)泵(beng)(beng)(beng)(beng)內(nei)的水(shui)(shui)(shui)流不(bu)流到外(wai)面來也不(bu)讓(rang)(rang)外(wai)面的空氣進入(ru)到泵(beng)(beng)(beng)(beng)內(nei)。始終保持水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)內(nei)的真空！當泵(beng)(beng)(beng)(beng)軸與填(tian)料(liao)(liao)(liao)摩擦產(chan)生熱量就要靠水(shui)(shui)(shui)封(feng)(feng)(feng)管住水(shui)(shui)(shui)到水(shui)(shui)(shui)封(feng)(feng)(feng)圈內(nei)使(shi)填(tian)料(liao)(liao)(liao)冷卻！保持水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)的正常運行(xing)。所以在水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)的運行(xing)巡回檢查過程(cheng)中對(dui)填(tian)料(liao)(liao)(liao)函的檢查是(shi)特別(bie)要注意！在運行(xing)600個小時左右就要對(dui)填(tian)料(liao)(liao)(liao)進行(xing)更換。

管道離(li)心(xin)泵供(gong)輸送(song)清(qing)水(shui)及物理(li)化學性質(zhi)類(lei)似于(yu)(yu)清(qing)水(shui)的其他液體(ti)(ti)(不(bu)含固(gu)體(ti)(ti)顆粒)，適用(yong)于(yu)(yu)工(gong)業 和城(cheng)市(shi)給排水(shui)、高層建筑增(zeng)(zeng)壓送(song)水(shui)、園(yuan)林噴灌、消防增(zeng)(zeng)壓、遠距離(li)輸送(song)、暖(nuan)通制冷循環(huan)、浴 室(shi)等冷暖(nuan)水(shui)循環(huan)增(zeng)(zeng)壓及設備配套，是(shi)無污染水(shui)源輸送(song)的理(li)想(xiang)設備。
