離心泵基本構造

離心泵的(de)(de)基本(ben)構造是(shi)由六部分(fen)組(zu)成的(de)(de)，分(fen)別是(shi)：葉(xie)(xie)(xie)輪(lun)，泵體，泵軸，軸承，密封環(huan)，填料(liao)函。 　　       1、 葉(xie)(xie)(xie)輪(lun)是(shi)離心泵的(de)(de)核(he)心部分(fen)，它轉速高輸出力(li)大，葉(xie)(xie)(xie)輪(lun)上的(de)(de)葉(xie)(xie)(xie)片(pian)又起到主要作用，葉(xie)(xie)(xie)輪(lun)在(zai)裝配(pei)前要通過靜平(ping)衡實驗。葉(xie)(xie)(xie)輪(lun)上的(de)(de)內(nei)外表面(mian)要求光滑，以減(jian)少水流的(de)(de)摩擦損失。

 　　2、泵(beng)體(ti)也稱泵(beng)殼，它是水泵(beng)的主(zhu)體(ti)。起到支撐固定作用，并與安裝軸承的托架相連接。

 　　3、 泵(beng)軸的(de)作用是借聯軸器和電(dian)動機(ji)(ji)相(xiang)連接，將電(dian)動機(ji)(ji)的(de)轉距傳(chuan)給(gei)葉輪(lun)，所(suo)以(yi)它是傳(chuan)遞機(ji)(ji)械能的(de)主(zhu)要(yao)部件。

 　　4、 軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)是(shi)(shi)套在(zai)(zai)泵(beng)軸(zhou)(zhou)(zhou)上支撐(cheng)泵(beng)軸(zhou)(zhou)(zhou)的(de)構件，有滾動(dong)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)和(he)滑動(dong)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)兩種。滾動(dong)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)使(shi)用(yong)牛油(you)(you)作為潤(run)滑劑(ji)加油(you)(you)要適當一般(ban)為2/3～3/4的(de)體積(ji)太多會發(fa)熱，太少(shao)又(you)(you)有響(xiang)聲并(bing)發(fa)熱！滑動(dong)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)離心(xin)泵(beng)結構使(shi)用(yong)的(de)是(shi)(shi)透(tou)明油(you)(you)作潤(run)滑劑(ji)的(de),加油(you)(you)到油(you)(you)位線。太多油(you)(you)要沿泵(beng)軸(zhou)(zhou)(zhou)滲出并(bing)且(qie)漂(piao)*，太少(shao)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)又(you)(you)要過(guo)熱燒(shao)壞造成事故！在(zai)(zai)水泵(beng)運(yun)行(xing)過(guo)程中軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)的(de)溫度(du)zui高在(zai)(zai)85℃一般(ban)運(yun)行(xing)在(zai)(zai)60度(du)左右，如(ru)果高了(le)就要查找原因（是(shi)(shi)否(fou)有雜質，油(you)(you)質是(shi)(shi)否(fou)發(fa)黑，是(shi)(shi)否(fou)進水）并(bing)及時處理(li)！

 　　5、 密(mi)封(feng)環(huan)(huan)(huan)又稱減漏(lou)環(huan)(huan)(huan)。葉輪與泵(beng)(beng)(beng)殼(ke)(ke)間的間隙(xi)過(guo)大會造成泵(beng)(beng)(beng)內高(gao)壓區的水(shui)經此間隙(xi)流向低壓區，影響(xiang)泵(beng)(beng)(beng)的出水(shui)量，效(xiao)率降低！間隙(xi)過(guo)小會造成葉輪與泵(beng)(beng)(beng)殼(ke)(ke)摩擦產生(sheng)磨損。為了增加(jia)回流阻力(li)減少(shao)內漏(lou)，延緩(huan)葉輪和泵(beng)(beng)(beng)殼(ke)(ke)的所使用壽(shou)命，在(zai)泵(beng)(beng)(beng)殼(ke)(ke)內緣(yuan)和葉輪外援結合處裝有密(mi)封(feng)環(huan)(huan)(huan)，密(mi)封(feng)的間隙(xi)保持在(zai)0.25～1.10mm之間為宜。

 　　6、 填(tian)(tian)(tian)(tian)料函主要由填(tian)(tian)(tian)(tian)料，水(shui)(shui)封(feng)環，填(tian)(tian)(tian)(tian)料筒(tong)，填(tian)(tian)(tian)(tian)料壓(ya)蓋，水(shui)(shui)封(feng)管組成。填(tian)(tian)(tian)(tian)料函的作用(yong)主要是(shi)為了封(feng)閉泵(beng)(beng)(beng)殼與(yu)泵(beng)(beng)(beng)軸之間的空隙，不讓(rang)泵(beng)(beng)(beng)內(nei)(nei)的水(shui)(shui)流不流到(dao)外面來也不讓(rang)外面的空氣進(jin)入到(dao)泵(beng)(beng)(beng)內(nei)(nei)。始終保持水(shui)(shui)泵(beng)(beng)(beng)內(nei)(nei)的真(zhen)空！當泵(beng)(beng)(beng)軸與(yu)填(tian)(tian)(tian)(tian)料摩擦產(chan)生熱量就(jiu)要靠水(shui)(shui)封(feng)管住水(shui)(shui)到(dao)水(shui)(shui)封(feng)圈內(nei)(nei)使填(tian)(tian)(tian)(tian)料冷卻！保持水(shui)(shui)泵(beng)(beng)(beng)的正常運(yun)行(xing)。所(suo)以(yi)在水(shui)(shui)泵(beng)(beng)(beng)的運(yun)行(xing)巡回(hui)檢查過程中(zhong)對填(tian)(tian)(tian)(tian)料函的檢查是(shi)特別要注意！在運(yun)行(xing)600個(ge)小(xiao)時左(zuo)右就(jiu)要對填(tian)(tian)(tian)(tian)料進(jin)行(xing)更(geng)換。
