冷却塔电机不转维修

　　冷却塔风机电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)不(bu)(bu)(bu)转的(de)(de)(de)(de)(de)原(yuan)(yuan)因主要有(you)：绕(rao)(rao)组(zu)断(duan)(duan)路、缺油抱轴(zhou)(zhou)(zhou)、电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容异常(chang)等。从(cong)对(dui)(dui)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)的(de)(de)(de)(de)(de)维修(xiu)实(shi)(shi)践来看(kan)，后(hou)(hou)两(liang)种故障居多。对(dui)(dui)于不(bu)(bu)(bu)转的(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)，我的(de)(de)(de)(de)(de) 维修(xiu)步(bu)骤是(shi)(shi)(shi)(shi)(shi)，测(ce)(ce)插头、转电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)、量(liang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容、再处理(li)(li)。 第一(yi)(yi)步(bu)，测(ce)(ce)量(liang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)运行和调速绕(rao)(rao)组(zu)。先(xian)(xian)把电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)定时器(qi)(qi)旋转一(yi)(yi)下，当听(ting)到(dao)有(you)嗒(da)(da)嗒(da)(da)声时，说(shuo)(shuo)明(ming)定时器(qi)(qi)是(shi)(shi)(shi)(shi)(shi)正(zheng)(zheng)常(chang)的(de)(de)(de)(de)(de)。如(ru)(ru)(ru)果(guo)(guo)(guo)(guo)没有(you)嗒(da)(da)嗒(da)(da)声，说(shuo)(shuo)明(ming)定时器(qi)(qi) 损(sun)坏。如(ru)(ru)(ru)果(guo)(guo)(guo)(guo)无(wu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)值(zhi)(zhi)，可(ke)(ke)(ke)(ke)(ke)能(neng)(neng)是(shi)(shi)(shi)(shi)(shi)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)绕(rao)(rao)组(zu)烧(shao)毁(hui)断(duan)(duan)路。对(dui)(dui)串(chuan)有(you)热熔(rong)断(duan)(duan)器(qi)(qi)的(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)，可(ke)(ke)(ke)(ke)(ke)能(neng)(neng)是(shi)(shi)(shi)(shi)(shi)热熔(rong)断(duan)(duan)器(qi)(qi)开(kai)路，还应拆(chai)开(kai)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)看(kan)一(yi)(yi)看(kan)，如(ru)(ru)(ru)果(guo)(guo)(guo)(guo)只(zhi)是(shi)(shi)(shi)(shi)(shi)开(kai)路，短接(jie) 热熔(rong)断(duan)(duan)器(qi)(qi)即(ji)可(ke)(ke)(ke)(ke)(ke)恢(hui)复正(zheng)(zheng)常(chang)。档位开(kai)关全部损(sun)坏，但(dan)可(ke)(ke)(ke)(ke)(ke)能(neng)(neng)性(xing)不(bu)(bu)(bu)大。 第二步(bu)，检查是(shi)(shi)(shi)(shi)(shi)否抱轴(zhou)(zhou)(zhou)，拆(chai)开(kai)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)护罩，用(yong)手(shou)旋动(dong)(dong)(dong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)轴(zhou)(zhou)(zhou)，如(ru)(ru)(ru)果(guo)(guo)(guo)(guo)转不(bu)(bu)(bu)动(dong)(dong)(dong)，说(shuo)(shuo)明(ming)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)抱轴(zhou)(zhou)(zhou)严重。拆(chai)开(kai)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)，先(xian)(xian)清除前后(hou)(hou)轴(zhou)(zhou)(zhou)套和电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)轴(zhou)(zhou)(zhou)上(shang)(shang)的(de)(de)(de)(de)(de)油污 、锈迹，然后(hou)(hou)在(zai)前后(hou)(hou)轴(zhou)(zhou)(zhou)套的(de)(de)(de)(de)(de)油毡(zhan)上(shang)(shang)加(jia)足(zu)缝纫机(ji)(ji)(ji)(ji)(ji)油，大部分电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)都能(neng)(neng)排除故障。 第三步(bu)，测(ce)(ce)量(liang)启(qi)(qi)动(dong)(dong)(dong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容，如(ru)(ru)(ru)果(guo)(guo)(guo)(guo)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)轴(zhou)(zhou)(zhou)旋转灵活，就(jiu)(jiu)要测(ce)(ce)量(liang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)启(qi)(qi)动(dong)(dong)(dong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容。首先(xian)(xian)，用(yong)万用(yong)表(biao)R×100Ω档，测(ce)(ce)量(liang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)启(qi)(qi)动(dong)(dong)(dong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容两(liang)端，整个 电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)运行、启(qi)(qi)动(dong)(dong)(dong)和调速绕(rao)(rao)组(zu)的(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)值(zhi)(zhi)，即(ji)黑色和**引线的(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)值(zhi)(zhi)。 能(neng)(neng)动(dong)(dong)(dong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)的(de)(de)(de)(de)(de)维修(xiu) 对(dui)(dui)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)能(neng)(neng)动(dong)(dong)(dong)的(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)，我是(shi)(shi)(shi)(shi)(shi)根(gen)据实(shi)(shi)际情况，一(yi)(yi)步(bu) 到(dao)位。而不(bu)(bu)(bu)是(shi)(shi)(shi)(shi)(shi)象(xiang)上(shang)(shang)述那样，按部就(jiu)(jiu)班地进行维修(xiu)。如(ru)(ru)(ru)果(guo)(guo)(guo)(guo)用(yong)户说(shuo)(shuo)，电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)先(xian)(xian)慢慢转，然后(hou)(hou)渐渐变快(kuai)。根(gen)据经验(yan)，一(yi)(yi)般是(shi)(shi)(shi)(shi)(shi)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)轻微抱轴(zhou)(zhou)(zhou)。原(yuan)(yuan)因是(shi)(shi)(shi)(shi)(shi)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian) 风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)润滑油初(chu)期缺失。直接(jie)拆(chai)开(kai)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)，在(zai)前后(hou)(hou)轴(zhou)(zhou)(zhou)套的(de)(de)(de)(de)(de)油毡(zhan)上(shang)(shang)加(jia)足(zu)缝纫机(ji)(ji)(ji)(ji)(ji)油，一(yi)(yi)般即(ji)可(ke)(ke)(ke)(ke)(ke)修(xiu)复。 遥控(kong)(kong)(kong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)，上(shang)(shang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)就(jiu)(jiu)转故障的(de)(de)(de)(de)(de)排除 现在(zai)的(de)(de)(de)(de)(de)遥 控(kong)(kong)(kong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)控(kong)(kong)(kong)制(zhi)执行元(yuan)件基(ji)本上(shang)(shang)都是(shi)(shi)(shi)(shi)(shi)可(ke)(ke)(ke)(ke)(ke)控(kong)(kong)(kong)硅。从(cong)原(yuan)(yuan)理(li)(li)可(ke)(ke)(ke)(ke)(ke)知可(ke)(ke)(ke)(ke)(ke)控(kong)(kong)(kong)硅实(shi)(shi)质等同于开(kai)关可(ke)(ke)(ke)(ke)(ke)控(kong)(kong)(kong)硅击穿(chuan)等同于开(kai)关接(jie)通(tong)(tong)。接(jie)通(tong)(tong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)风(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)(shan)(shan)(shan)(shan)当然就(jiu)(jiu)转了。
