1、中頻爐電容絕(jue)緣部分問(wen)題及改(gai)進
 

　　中(zhong)頻(pin)爐電(dian)(dian)(dian)(dian)容(rong)器出現問題的原(yuan)因(yin)為(wei)：原(yuan)廠家(jia)(jia)電(dian)(dian)(dian)(dian)容(rong)柜里電(dian)(dian)(dian)(dian)容(rong)用的是10mm厚(hou)、長10cm\寬5cm的電(dian)(dian)(dian)(dian)木(mu)板(ban)與下面(mian)支架鐵(tie)板(ban)隔離絕(jue)緣(yuan)，電(dian)(dian)(dian)(dian)容(rong)器上面(mian)水(shui)管出現問題時，水(shui)就會(hui)把電(dian)(dian)(dian)(dian)容(rong)器和鐵(tie)板(ban)連接起來造成短路(因(yin)絕(jue)緣(yuan)板(ban)與鐵(tie)架只有10mm)，從而導(dao)致(zhi)電(dian)(dian)(dian)(dian)容(rong)器漏油、打火、過流保(bao)護動作等現象。經過研究探索我將原(yuan)廠家(jia)(jia)的10mm厚(hou)電(dian)(dian)(dian)(dian)木(mu)板(ban)去(qu)掉，改為(wei)2寸(cun)見(jian)方的電(dian)(dian)(dian)(dian)木(mu)板(ban)4根(gen)，將8臺電(dian)(dian)(dian)(dian)容(rong)器全部支起，徹底(di)解決了電(dian)(dian)(dian)(dian)容(rong)器冷卻水(shui)管漏水(shui)而造成對地絕(jue)緣(yuan)燒壞電(dian)(dian)(dian)(dian)容(rong)器的問題，每臺爐年(nian)節約電(dian)(dian)(dian)(dian)容(rong)器數臺，同時也確保(bao)了中(zhong)頻(pin)爐的正常運行。
 

　　2、感應加熱匯流母(mu)線的改進
 

　　感應(ying)(ying)(ying)加熱(re)裝置(zhi)是指(zhi)利用(yong)電(dian)流產生(sheng)的(de)(de)(de)(de)(de)(de)磁場非接觸(chu)地對感應(ying)(ying)(ying)器(qi)內的(de)(de)(de)(de)(de)(de)金屬(shu)工件(jian)實現渦(wo)流加熱(re)的(de)(de)(de)(de)(de)(de)裝置(zhi)。而我(wo)分(fen)公司的(de)(de)(de)(de)(de)(de)感應(ying)(ying)(ying)器(qi)一般(ban)由(you)環形的(de)(de)(de)(de)(de)(de)通(tong)水銅(tong)(tong)管(guan)(guan)(guan)制成(cheng)，為了(le)減(jian)(jian)少(shao)裝置(zhi)的(de)(de)(de)(de)(de)(de)容量(liang)，目前所(suo)采用(yong)的(de)(de)(de)(de)(de)(de)絕大(da)部分(fen)是將負載電(dian)路設計為由(you)感應(ying)(ying)(ying)器(qi)和補償電(dian)容器(qi)組成(cheng)的(de)(de)(de)(de)(de)(de)并(bing)聯(lian)諧振電(dian)路。該諧振電(dian)路的(de)(de)(de)(de)(de)(de)最大(da)特點就(jiu)是電(dian)流大(da)、頻率高。由(you)于我(wo)車間所(suo)用(yong)的(de)(de)(de)(de)(de)(de)冷卻水中雜(za)質較多(duo)，但匯流母(mu)線上的(de)(de)(de)(de)(de)(de)冷卻銅(tong)(tong)管(guan)(guan)(guan)是方形的(de)(de)(de)(de)(de)(de)，并(bing)有很多(duo)轉彎處，使(shi)銅(tong)(tong)管(guan)(guan)(guan)內產生(sheng)很多(duo)水垢(gou)，這(zhe)樣就(jiu)造(zao)成(cheng)管(guan)(guan)(guan)路堵塞(sai)使(shi)匯流母(mu)線過熱(re)且很難(nan)疏通(tong)，只(zhi)能更換(huan)。根(gen)據以(yi)上情況，我(wo)將方形銅(tong)(tong)管(guan)(guan)(guan)改為圓形銅(tong)(tong)管(guan)(guan)(guan)，并(bing)盡量(liang)減(jian)(jian)少(shao)轉彎，這(zhe)樣就(jiu)使(shi)管(guan)(guan)(guan)路不易(yi)堵塞(sai)，銅(tong)(tong)管(guan)(guan)(guan)內的(de)(de)(de)(de)(de)(de)水垢(gou)也容易(yi)清除。改進后的(de)(de)(de)(de)(de)(de)母(mu)線故障發生(sheng)率明顯(xian)降低，母(mu)線損壞次數明顯(xian)減(jian)(jian)少(shao)，并(bing)且設備運行效(xiao)果良好。
 

　　3、中頻爐電(dian)容連接故(gu)障的(de)改進
 

　　中頻爐運(yun)行(xing)中故障(zhang)頻發，具體表現為(wei)：過(guo)流，分(fen)(fen)析(xi)：70%故障(zhang)是(shi)在(zai)(zai)水(shui)(shui)冷(leng)電(dian)容(rong)(rong)(rong)器(qi)上，究其(qi)原因，水(shui)(shui)冷(leng)電(dian)容(rong)(rong)(rong)器(qi)是(shi)靠水(shui)(shui)冷(leng)卻(que)，冷(leng)卻(que)水(shui)(shui)管是(shi)塑料管，運(yun)行(xing)中電(dian)容(rong)(rong)(rong)器(qi)電(dian)流大(da)(da)(da)，連(lian)(lian)接(jie)(jie)部分(fen)(fen)經常(chang)漏水(shui)(shui)、滲水(shui)(shui)現象(xiang)較為(wei)頻繁，水(shui)(shui)冷(leng)電(dian)容(rong)(rong)(rong)器(qi)與母排(pai)連(lian)(lian)接(jie)(jie)又是(shi)軟連(lian)(lian)接(jie)(jie)，用的(de)是(shi)銅(tong)(tong)緶(bian)(bian)就(jiu)會潮(chao)濕，因銅(tong)(tong)緶(bian)(bian)有大(da)(da)(da)電(dian)流流過(guo)，溫(wen)度很(hen)高，水(shui)(shui)漏到銅(tong)(tong)緶(bian)(bian)上就(jiu)會出現變藍、變黑、接(jie)(jie)觸不(bu)良，打(da)火花、燒斷銅(tong)(tong)緶(bian)(bian)、燒壞電(dian)容(rong)(rong)(rong)器(qi)，造成過(guo)流動作而被迫停爐。 經過(guo)分(fen)(fen)析(xi)研(yan)究將(jiang)怕水(shui)(shui)的(de)銅(tong)(tong)緶(bian)(bian)改成銅(tong)(tong)排(pai)連(lian)(lian)接(jie)(jie)，我在(zai)(zai)單臺(tai)爐上反復(fu)實驗，結果非常(chang)成功，得到車(che)間(jian)領(ling)導認(ren)證后(hou)，對2臺(tai)中頻爐進行(xing)改造，使故障(zhang)率大(da)(da)(da)大(da)(da)(da)降低。
 

　　4、中頻爐感應圈絕緣的問題及改進：
 

　　原(yuan)(yuan)有(you)感(gan)(gan)(gan)(gan)應(ying)(ying)圈(quan)絕緣(yuan)是先用(yong)玻(bo)璃(li)絲(si)(si)帶(dai)(dai)包(bao)扎，然后(hou)(hou)刷絕緣(yuan)漆，設備運(yun)行一段時(shi)間(jian)后(hou)(hou)，玻(bo)璃(li)絲(si)(si)帶(dai)(dai)就會(hui)脫(tuo)落、絕緣(yuan)老化，因耐火材料(liao)(liao)是主(zhu)(zhu)感(gan)(gan)(gan)(gan)應(ying)(ying)圈(quan)內襯，主(zhu)(zhu)感(gan)(gan)(gan)(gan)應(ying)(ying)圈(quan)本身(shen)無間(jian)隙無法進行重新包(bao)扎處理(li)，嚴重時(shi)就必須拆(chai)掉(diao)耐火材料(liao)(liao)，將感(gan)(gan)(gan)(gan)應(ying)(ying)圈(quan)取出(chu)重新包(bao)扎處理(li)，而拆(chai)掉(diao)的(de)(de)耐火材料(liao)(liao)多數都不能重新再用(yong)，每次浪費的(de)(de)耐火材料(liao)(liao)直(zhi)接損失(shi)(shi)很大，還(huan)不算人工費、停(ting)產期間(jian)的(de)(de)停(ting)產損失(shi)(shi)費。為了解決這一問(wen)題(ti)(ti)，我在(zai)(zai)網上查(cha)找最新資料(liao)(liao)，結(jie)(jie)合(he)自己多年的(de)(de)實際經驗，最終選擇了用(yong)耐高溫速干絕緣(yuan)漆直(zhi)接刷到(dao)主(zhu)(zhu)感(gan)(gan)(gan)(gan)應(ying)(ying)圈(quan)上代替(ti)原(yuan)(yuan)有(you)玻(bo)璃(li)絲(si)(si)帶(dai)(dai)包(bao)扎的(de)(de)方法先在(zai)(zai)一臺160kw小中頻感(gan)(gan)(gan)(gan)應(ying)(ying)燒結(jie)(jie)爐上試驗，結(jie)(jie)果(guo)非常成功，徹底解決了感(gan)(gan)(gan)(gan)應(ying)(ying)圈(quan)絕緣(yuan)老化、易匝(za)間(jian)短路造成過流(liu)的(de)(de)問(wen)題(ti)(ti)，并用(yong)瓷管代替(ti)感(gan)(gan)(gan)(gan)應(ying)(ying)圈(quan)內部的(de)(de)耐火材料(liao)(liao)，這樣就節約(yue)了大量(liang)的(de)(de)耐火材料(liao)(liao)、人工等費用(yong)，產品質量(liang)也得到(dao)了保(bao)證。
