鉆桿鉗的(de)操作(zuo)程序是怎樣的(de)？

鉆(zhan)桿鉗(qian)(qian)操作(zuo)規程：把閘閥(fa)開到很大(da)(da)口徑。手(shou)(shou)(shou)(shou)輪(lun)(lun)(lun)(lun)順時(shi)(shi)針(zhen)轉(zhuan)動(dong)(dong)(dong)(dong)進刀(dao)(dao)(dao)，當(dang)中心鉆(zhan)（鉆(zhan)頭）頂住主管(guan)時(shi)(shi)，手(shou)(shou)(shou)(shou)輪(lun)(lun)(lun)(lun)反(fan)轉(zhuan)半圈（防(fang)止打刀(dao)(dao)(dao)）。啟(qi)(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)機，順時(shi)(shi)針(zhen)方向(xiang)緩慢(man)轉(zhuan)動(dong)(dong)(dong)(dong)手(shou)(shou)(shou)(shou)輪(lun)(lun)(lun)(lun)給刀(dao)(dao)(dao)，手(shou)(shou)(shou)(shou)感(gan)鉆(zhan)穿(chuan)管(guan)壁(bi)后(hou)(hou)切(qie)斷電(dian)(dian)源(yuan)。斷電(dian)(dian)后(hou)(hou)，可手(shou)(shou)(shou)(shou)動(dong)(dong)(dong)(dong)進刀(dao)(dao)(dao)，表(biao)示已鉆(zhan)通。鉆(zhan)桿大(da)(da)鉗(qian)(qian)順時(shi)(shi)針(zhen)轉(zhuan)動(dong)(dong)(dong)(dong)手(shou)(shou)(shou)(shou)輪(lun)(lun)(lun)(lun)進刀(dao)(dao)(dao)，桶刀(dao)(dao)(dao)碰到管(guan)壁(bi)時(shi)(shi)反(fan)轉(zhuan)半圈（防(fang)止打刀(dao)(dao)(dao)）。再次啟(qi)(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)機，順時(shi)(shi)針(zhen)方向(xiang)慢(man)慢(man)轉(zhuan)動(dong)(dong)(dong)(dong)手(shou)(shou)(shou)(shou)輪(lun)(lun)(lun)(lun)給刀(dao)(dao)(dao)。桶刀(dao)(dao)(dao)切(qie)斷管(guan)壁(bi)后(hou)(hou)，切(qie)斷電(dian)(dian)源(yuan)。切(qie)斷電(dian)(dian)源(yuan)后(hou)(hou)，如果手(shou)(shou)(shou)(shou)動(dong)(dong)(dong)(dong)進刀(dao)(dao)(dao)時(shi)(shi)手(shou)(shou)(shou)(shou)輪(lun)(lun)(lun)(lun)不(bu)轉(zhuan)動(dong)(dong)(dong)(dong)，則表(biao)示切(qie)割未完(wan)成(cheng)。需要將手(shou)(shou)(shou)(shou)輪(lun)(lun)(lun)(lun)反(fan)轉(zhuan)半圈，重新啟(qi)(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)機，然后(hou)(hou)繼(ji)續緩慢(man)進給刀(dao)(dao)(dao)具(ju)。當(dang)電(dian)(dian)機切(qie)斷電(dian)(dian)源(yuan)時(shi)(shi)，手(shou)(shou)(shou)(shou)輪(lun)(lun)(lun)(lun)可以轉(zhuan)動(dong)(dong)(dong)(dong)進刀(dao)(dao)(dao)，表(biao)示孔的切(qie)割已經(jing)完(wan)成(cheng)。

鉆桿鉗在完全封閉的(de)(de)腔體中進(jin)行，工(gong)具的(de)(de)切割過(guo)程(cheng)與空氣隔絕，沒有火災(zai)或(huo)爆炸的(de)(de)可能(neng)，對(dui)環境無污染。其裝(zhuang)置為不(bu)停(ting)機(ji)生產條件下的(de)(de)裸眼接頭，適用于除氧(yang)氣以外的(de)(de)任何介(jie)質及各種不(bu)同口徑的(de)(de)管道。

鉆(zhan)桿鉗是一種在(zai)承受壓力或(huo)(huo)開孔時使用的(de)管(guan)道和容器上制作接(jie)頭的(de)方法。為輸入或(huo)(huo)輸出材料添加分(fen)支管(guan)道。設置溫度探(tan)頭監測點(dian)，為設備(bei)（阻斷設備(bei)）提供連接(jie)點(dian)。帶壓開孔是在(zai)一個完(wan)全封閉的(de)空腔內進行的(de)。刀具(ju)切削過(guo)程與(yu)空氣(qi)隔(ge)絕，無明火(huo)、明火(huo)等(deng)。沒有爆(bao)炸的(de)可能，對環境無污染(ran)。其裝置為不(bu)停機生產條件(jian)下的(de)裸眼接(jie)頭，適用于除氧氣(qi)以(yi)外的(de)任何介質及(ji)各種不(bu)同(tong)口(kou)徑的(de)管(guan)道。
