自動磨刀機故障檢測

故障現象一:

能(neng)正常翻刀,不能(neng)磨刀。

分析(xi)與檢修:在安靜(jing)的環境中通(tong)電(dian)(dian)(dian)試機(ji)(ji)(ji),正確操作(zuo)(zuo)面板(ban)上各(ge)功(gong)能(neng)開(kai)關(guan)(guan)均能(neng)靈活功(gong)作(zuo)(zuo)。同時認(ren)真觀(guan)察(cha)各(ge)個功(gong)能(neng)指示燈,亮、滅(mie)亦正常(chang)(chang),仔細聆聽(ting)機(ji)(ji)(ji)內繼電(dian)(dian)(dian)器、行(xing)程開(kai)關(guan)(guan)、機(ji)(ji)(ji)械傳(chuan)動部件等均無異(yi)常(chang)(chang)聲響(xiang),也沒聞到(dao)任(ren)何焦糊(hu)味。由以上檢查可(ke)以認(ren)定控制電(dian)(dian)(dian)路基本(ben)正常(chang)(chang),于是(shi)斷開(kai)電(dian)(dian)(dian)源,打開(kai)前面板(ban)檢查內部故障(zhang)點。通(tong)電(dian)(dian)(dian)時,翻(fan)刀(dao)(dao)(dao)電(dian)(dian)(dian)機(ji)(ji)(ji)正常(chang)(chang)運行(xing),但磨刀(dao)(dao)(dao)電(dian)(dian)(dian)機(ji)(ji)(ji)卻絲毫不動,取(qu)下傳(chuan)動皮帶,待翻(fan)刀(dao)(dao)(dao)動作(zuo)(zuo)結束(shu)時立即用手指輕(qing)輕(qing)援動磨刀(dao)(dao)(dao)電(dian)(dian)(dian)機(ji)(ji)(ji)飛輪,此時電(dian)(dian)(dian)機(ji)(ji)(ji)即能(neng)常(chang)(chang)速運轉。測電(dian)(dian)(dian)機(ji)(ji)(ji)主繞組(M,C端)直流電(dian)(dian)(dian)阻約(yue)80,翻(fan)繞組((S.C端)約(yue)216,(M,S端)約(yue)295,這說明(ming)電(dian)(dian)(dian)機(ji)(ji)(ji)正常(chang)(chang),再側量(liang)啟(qi)動電(dian)(dian)(dian)容C兩端,容量(liang)為正無窮大,說明(ming)電(dian)(dian)(dian)容已開(kai)路,拆下一(yi)看果然外壁鼓起一(yi)個很大包塊。更挽同型號電(dian)(dian)(dian)容后試機(ji)(ji)(ji),整機(ji)(ji)(ji)恢(hui)復了(le)正常(chang)(chang)工作(zuo)(zuo)。
