金(jin)屬激(ji)光焊(han)接機疝燈(deng)工作原理及故障分(fen)析

疝燈是金屬激光焊接機一個重(zhong)要的(de)零部件，它能激(ji)(ji)發(fa)激(ji)(ji)光(guang)(guang)物質產生(sheng)高強度的(de)激(ji)(ji)光(guang)(guang)光(guang)(guang)束。氙(xian)燈(deng)是一種充滿氙(xian)氣的(de)柱狀(zhuang)玻璃燈(deng)，其陽極和陰(yin)極直接接觸氣體，分(fen)布在燈(deng)具兩端的(de)電(dian)(dian)(dian)極與(yu)內部電(dian)(dian)(dian)極直接連接。在金(jin)屬激(ji)(ji)光(guang)(guang)焊接機中(zhong)，氙(xian)燈(deng)可分(fen)為(wei)兩種狀(zhuang)態：預(yu)燃(ran)狀(zhuang)態和放電(dian)(dian)(dian)狀(zhuang)態。它的(de)工(gong)作(zuo)原理(li)是通(tong)過(guo)向(xiang)外電(dian)(dian)(dian)極施(shi)加高壓脈(mo)沖使(shi)(shi)燈(deng)管中(zhong)的(de)惰性氣體電(dian)(dian)(dian)離，使(shi)(shi)其進入預(yu)燃(ran)狀(zhuang)態并保(bao)持。然(ran)后，施(shi)加大電(dian)(dian)(dian)流使(shi)(shi)其過(guo)渡(du)到高電(dian)(dian)(dian)流密度的(de)電(dian)(dian)(dian)弧放電(dian)(dian)(dian)，產生(sheng)強烈的(de)閃光(guang)(guang)，從而激(ji)(ji)發(fa)金(jin)屬激(ji)(ji)光(guang)(guang)焊接機的(de)激(ji)(ji)光(guang)(guang)發(fa)生(sheng)器。

金(jin)屬激(ji)(ji)光(guang)焊接機(ji)疝(shan)(shan)燈(deng)工(gong)(gong)作(zuo)的過程看起來比較(jiao)復雜，但(dan)人們只需(xu)要(yao)啟動(dong)(dong)開關電源(yuan)，就(jiu)(jiu)可(ke)以激(ji)(ji)發其工(gong)(gong)作(zuo)，操作(zuo)非常簡(jian)單(dan)便捷。當人們啟動(dong)(dong)開關電源(yuan)的時候(hou)，可(ke)能(neng)會出現疝(shan)(shan)燈(deng)無(wu)法(fa)(fa)正常工(gong)(gong)作(zuo)的情況，這(zhe)時就(jiu)(jiu)需(xu)要(yao)做故(gu)障(zhang)排查(cha)工(gong)(gong)作(zuo)。首先，要(yao)檢(jian)查(cha)金(jin)屬激(ji)(ji)光(guang)焊接機(ji)的預(yu)燃板電壓是(shi)(shi)否(fou)有220V，電壓不足時，將無(wu)法(fa)(fa)啟動(dong)(dong)疝(shan)(shan)燈(deng)。其次，要(yao)檢(jian)查(cha)疝(shan)(shan)燈(deng)的保險(xian)絲是(shi)(shi)否(fou)損壞，方(fang)法(fa)(fa)比較(jiao)簡(jian)單(dan)，看疝(shan)(shan)燈(deng)兩(liang)端的鎢絲是(shi)(shi)否(fou)變(bian)黑(hei)(hei)，如果發黑(hei)(hei)，就(jiu)(jiu)需(xu)要(yao)直接更(geng)換疝(shan)(shan)燈(deng)。另外，當前面兩(liang)種(zhong)檢(jian)查(cha)都無(wu)異常時，可(ke)能(neng)是(shi)(shi)鎮流(liu)器(qi)出現了故(gu)障(zhang)，需(xu)要(yao)更(geng)換。一般來講，更(geng)換金(jin)屬激(ji)(ji)光(guang)焊接機(ji)疝(shan)(shan)燈(deng)和鎮流(liu)器(qi)等零部件時，需(xu)要(yao)專業的維(wei)修人員。工(gong)(gong)廠可(ke)以安排廠內的設備維(wei)修師傅，或者聯系激(ji)(ji)光(guang)焊接機(ji)生產廠家上門更(geng)換。
