數(shu)控母(mu)線加(jia)工(gong)機(ji)銅(tong)排(pai)加(jia)工(gong)機(ji)是我司主要產品(pin)之一。下(xia)面小(xiao)編(bian)為您分(fen)享數(shu)控母(mu)線加(jia)工(gong)機(ji)銅(tong)排(pai)加(jia)工(gong)機(ji)的(de)油溫(wen)故障處理方法：

數控母線(xian)加工機(ji)銅排(pai)加工機(ji)油(you)(you)(you)溫(wen)(wen)(wen)表指(zhi)示(shi)的是(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)頂(ding)(ding)層油(you)(you)(you)溫(wen)(wen)(wen),運(yun)行中的油(you)(you)(you)溫(wen)(wen)(wen)監視點(dian)為(wei)(wei)85℃,溫(wen)(wen)(wen)升是(shi)指(zhi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)頂(ding)(ding)層油(you)(you)(you)溫(wen)(wen)(wen)減(jian)去環境(jing)溫(wen)(wen)(wen)度(du)(du),運(yun)行中變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)在(zai)外(wai)溫(wen)(wen)(wen)40℃時(shi)(shi),其溫(wen)(wen)(wen)升不(bu)(bu)(bu)得超(chao)過(guo)(guo)(guo)55℃,運(yun)行中以(yi)(yi)頂(ding)(ding)層油(you)(you)(you)溫(wen)(wen)(wen)為(wei)(wei)準(zhun),溫(wen)(wen)(wen)升是(shi)參考數據。若變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)在(zai)同等(deng)(deng)條(tiao)件下(xia)(xia)(環境(jing)溫(wen)(wen)(wen)度(du)(du)、負(fu)荷(he)、油(you)(you)(you)位等(deng)(deng)),油(you)(you)(you)溫(wen)(wen)(wen)比平時(shi)(shi)高出10℃或(huo)(huo)(huo)負(fu)荷(he)不(bu)(bu)(bu)變(bian)(bian)(bian)(bian)但溫(wen)(wen)(wen)度(du)(du)不(bu)(bu)(bu)斷上升,并且(qie)冷(leng)(leng)卻(que)裝置(zhi)正常(chang)(chang)(chang)運(yun)行,則(ze)認為(wei)(wei)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)發生內(nei)部故(gu)障(zhang)(zhang)(應注意溫(wen)(wen)(wen)度(du)(du)表有(you)無誤差或(huo)(huo)(huo)失(shi)靈(ling))。我國變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)的溫(wen)(wen)(wen)升標(biao)準(zhun),均以(yi)(yi)環境(jing)溫(wen)(wen)(wen)度(du)(du)40℃為(wei)(wei)準(zhun),故(gu)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)頂(ding)(ding)層油(you)(you)(you)溫(wen)(wen)(wen)一般不(bu)(bu)(bu)得超(chao)過(guo)(guo)(guo)40℃+55℃=95℃。頂(ding)(ding)層油(you)(you)(you)溫(wen)(wen)(wen)如(ru)超(chao)過(guo)(guo)(guo)95℃,其內(nei)部線(xian)圈的溫(wen)(wen)(wen)度(du)(du)就要超(chao)過(guo)(guo)(guo)線(xian)圈絕緣物的耐熱(re)強度(du)(du),為(wei)(wei)了使(shi)(shi)絕緣不(bu)(bu)(bu)致過(guo)(guo)(guo)快老化,所(suo)以(yi)(yi)規(gui)定變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)頂(ding)(ding)層油(you)(you)(you)溫(wen)(wen)(wen)的監視應控制在(zai)85℃以(yi)(yi)下(xia)(xia)。導致變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)溫(wen)(wen)(wen)度(du)(du)異常(chang)(chang)(chang)的原因內(nei)部故(gu)障(zhang)(zhang)引起(qi)溫(wen)(wen)(wen)度(du)(du)異常(chang)(chang)(chang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)內(nei)部故(gu)障(zhang)(zhang)如(ru)匝間短(duan)路(lu)(lu)或(huo)(huo)(huo)層間短(duan)路(lu)(lu),線(xian)圈對圍屏放電,內(nei)部引線(xian)接頭發熱(re),鐵(tie)芯(xin)多(duo)點(dian)接地使(shi)(shi)渦(wo)流增大過(guo)(guo)(guo)熱(re),零序不(bu)(bu)(bu)平衡電流等(deng)(deng)漏磁(ci)通(tong)與(yu)鐵(tie)件油(you)(you)(you)箱形成回(hui)路(lu)(lu)而發熱(re)等(deng)(deng)因素(su)引起(qi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)溫(wen)(wen)(wen)度(du)(du)異常(chang)(chang)(chang)時(shi)(shi),還將伴隨著(zhu)瓦斯(si)或(huo)(huo)(huo)差動保護動作(zuo),故(gu)障(zhang)(zhang)嚴重時(shi)(shi)還可(ke)能使(shi)(shi)防爆管或(huo)(huo)(huo)壓(ya)(ya)(ya)力釋放閥噴油(you)(you)(you),這時(shi)(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)應停(ting)用檢查。冷(leng)(leng)卻(que)器(qi)(qi)(qi)不(bu)(bu)(bu)正常(chang)(chang)(chang)運(yun)行或(huo)(huo)(huo)發生故(gu)障(zhang)(zhang)如(ru)潛油(you)(you)(you)泵(beng)停(ting)運(yun),風扇損壞(huai),散熱(re)管道積(ji)垢,冷(leng)(leng)卻(que)效率不(bu)(bu)(bu)良(liang),散熱(re)器(qi)(qi)(qi)閥門沒有(you)打開等(deng)(deng)原因引起(qi)溫(wen)(wen)(wen)度(du)(du)異常(chang)(chang)(chang)。應及時(shi)(shi)對冷(leng)(leng)卻(que)系統進(jin)行維護和(he)沖(chong)洗或(huo)(huo)(huo)投人備用冷(leng)(leng)卻(que)器(qi)(qi)(qi),否則(ze)就要調(diao)整(zheng)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)的負(fu)荷(he)。數控母線(xian)加工機(ji)銅排(pai)加工機(ji)溫(wen)(wen)(wen)度(du)(du)指(zhi)示(shi)器(qi)(qi)(qi)有(you)誤差或(huo)(huo)(huo)指(zhi)示(shi)失(shi)靈(ling),應更換溫(wen)(wen)(wen)度(du)(du)表。
