不(bu)銹鋼(gang)自吸泵(beng)電(dian)機部分　

　　1、接通電(dian)源(yuan)后無反應(ying)。多數是電(dian)源(yuan)插頭、電(dian)源(yuan)引出線和電(dian)機繞組短(duan)路(lu)所致。

　　2、難啟(qi)(qi)(qi)動(dong)或(huo)不能啟(qi)(qi)(qi)動(dong),且伴(ban)有(you)“嗡嗡”的聲音。檢修時(shi)可用小(xiao)竹(zhu)片按運轉方向快速撥動(dong)風葉,若電(dian)(dian)機(ji)(ji)迅速運轉起(qi)來,說明是啟(qi)(qi)(qi)動(dong)電(dian)(dian)容(rong)(rong)或(huo)啟(qi)(qi)(qi)動(dong)繞組損壞,應更換(huan)相同容(rong)(rong)量(liang)的電(dian)(dian)容(rong)(rong)或(huo)修理啟(qi)(qi)(qi)動(dong)繞組；若電(dian)(dian)機(ji)(ji)發卡,多是電(dian)(dian)機(ji)(ji)和泵頭的機(ji)(ji)械故障,如軸承損壞、葉輪卡死(si)等。

　　3、電機(ji)能運(yun)轉,但轉速(su)慢(man),且機(ji)殼過熱(re)、有燒(shao)焦臭味。多數是電機(ji)繞組短路所致(zhi),應拆開(kai)電機(ji),視損壞情(qing)況分別采用焊接(jie)、跳線、隔(ge)離、重繞等措施修復(fu)。

　　4、運轉時噪聲大、振動大。多(duo)數是軸(zhou)(zhou)承(cheng)(cheng)損壞或軸(zhou)(zhou)承(cheng)(cheng)與機(ji)殼(ke)(ke)的配(pei)合不當,需拆(chai)開(kai)電機(ji)檢查,若(ruo)是軸(zhou)(zhou)承(cheng)(cheng)損壞應更(geng)換(huan)；若(ruo)軸(zhou)(zhou)承(cheng)(cheng)跑(pao)外圓(yuan),可對(dui)泵(beng)殼(ke)(ke)的配(pei)合面采用(yong)鏨花(hua)處(chu)理(li)；若(ruo)軸(zhou)(zhou)承(cheng)(cheng)跑(pao)內(nei)圓(yuan),可對(dui)電機(ji)軸(zhou)(zhou)的磨損部位(wei)采用(yong)鏨花(hua)處(chu)理(li),磨損嚴重(zhong)的,采用(yong)先堆焊后車削(xue)的方法修復。

　　不銹鋼(gang)自吸泵(beng)泵(beng)頭部分(fen)

　　1、電機(ji)正常運轉但出水(shui)(shui)(shui)量(liang)少或(huo)根本不出水(shui)(shui)(shui)。這種情(qing)況(kuang)應首先檢(jian)(jian)查水(shui)(shui)(shui)泵(beng)的密封,檢(jian)(jian)查時(shi)(shi)應先拔下電源插頭(tou),用手堵住吸水(shui)(shui)(shui)口,把水(shui)(shui)(shui)泵(beng)灌滿水(shui)(shui)(shui),用嘴銜住出口使勁往里吹氣,觀察泵(beng)頭(tou)是(shi)否(fou)漏(lou)水(shui)(shui)(shui),漏(lou)水(shui)(shui)(shui)之(zhi)處(chu)也就是(shi)密封損(sun)壞(huai)之(zhi)處(chu)。常見的故(gu)障部位有(you)吸水(shui)(shui)(shui)口墊(dian)(dian)、出水(shui)(shui)(shui)口墊(dian)(dian)、葉(xie)輪蓋墊(dian)(dian),維修(xiu)時(shi)(shi)應更(geng)換。若無滿水(shui)(shui)(shui)現象,多(duo)是(shi)葉(xie)輪損(sun)壞(huai)、吸水(shui)(shui)(shui)室和(he)出水(shui)(shui)(shui)室之(zhi)間的擋(dang)水(shui)(shui)(shui)內隔蝕(shi)穿、泵(beng)頭(tou)擋(dang)水(shui)(shui)(shui)隔磨(mo)平、葉(xie)輪和(he)泵(beng)殼的間隙增(zeng)大(da)等,應更(geng)換葉(xie)輪和(he)泵(beng)殼。更(geng)換趺輪時(shi)(shi)應注意徹底清(qing)除(chu)泵(beng)內殘余的銅葉(xie)片(pian),以免再次(ci)損(sun)壞(huai)新葉(xie)輪。

　　2、機殼帶電。多數是(shi)水(shui)(shui)封損(sun)壞,水(shui)(shui)通過電機軸滲入電機內使電機絕緣性能惡化所致,可采用(yong)更換水(shui)(shui)封、烘干(gan)電機等(deng)方法修復。需要注意的是(shi),因為水(shui)(shui)泵長(chang)期與水(shui)(shui)接(jie)(jie)觸和(he)露天工(gong)作,極易(yi)受潮而造(zao)成(cheng)絕緣性能惡化,為了保證(zheng)人身安全(quan),電動不銹(xiu)鋼自(zi)吸泵應可靠接(jie)(jie)地。
