重(zhong)慶電機(ji)(ji)(ji)內部進(jin)水被腐(fu)蝕如何處理，由于電機(ji)(ji)(ji)本身密封(feng)不良(liang)，加之環境跑冒滴漏等現象(xiang)，使電機(ji)(ji)(ji)內部進(jin)水或進(jin)入其它帶有腐(fu)蝕性(xing)液體或氣體，電動(dong)機(ji)(ji)(ji)繞組絕緣(yuan)(yuan)受到浸蝕，最嚴重(zhong)部位或絕緣(yuan)(yuan)最薄弱處發生一點(dian)對(dui)地、相間短(duan)路或匝間短(duan)路現象(xiang)，從而導致電動(dong)機(ji)(ji)(ji)繞組局部燒壞。
解決方法：①盡量消除(chu)工(gong)藝和機械(xie)設備的(de)跑冒滴(di)漏現象(xiang);②檢修時注意搞好電(dian)機的(de)每個部位的(de)密封，例如在(zai)(zai)各法蘭涂(tu)少量704密封膠(jiao)，在(zai)(zai)螺栓(shuan)上涂(tu)抹(mo)油脂，必要時在(zai)(zai)接線(xian)盒等(deng)處加裝防(fang)滴(di)濺盒，如電(dian)機暴漏在(zai)(zai)易(yi)侵(qin)入液體和污物的(de)地(di)方應做保護罩(zhao);③對在(zai)(zai)此環(huan)境中運行(xing)的(de)電(dian)機要縮短小(xiao)修和中修周期，嚴重時要及(ji)時進行(xing)中修。
