給大(da)(da)家介紹下爆破聚能(neng)管的(de)技(ji)術原理∶炸藥爆炸產(chan)(chan)生(sheng)的(de)爆轟波(bo)通(tong)過聚能(neng)管的(de)聚能(neng)槽，將炸藥的(de)動(dong)能(neng)、勢(shi)能(neng)轉換(huan)成(cheng)高(gao)壓、高(gao)速、高(gao)能(neng)的(de)射(she)流(liu)(liu)，切割演示成(cheng)縫(feng)(feng)。射(she)流(liu)(liu)在孔(kong)壁產(chan)(chan)生(sheng)射(she)流(liu)(liu)壓力達7000MPa，巖石動(dong)載抗(kang)壓強(qiang)度為(wei)200MPa，抗(kang)拉為(wei)1/8～1/10的(de)抗(kang)壓強(qiang)度，相鄰兩炮孔(kong)互(hu)為(wei)鄰空(kong)面，疊加(jia)后的(de)壓縮波(bo)變為(wei)稀疏波(bo)，在兩炮眼(yan)連線(xian)上(shang)使(shi)巖石結構斷裂(lie)，形成(cheng)裂(lie)紋。準靜態氣體(ti)膨脹，靜態壓力在兩炮孔(kong)最短(duan)連線(xian)兩側產(chan)(chan)生(sheng)拉力使(shi)巖石裂(lie)縫(feng)(feng)進一步擴展。根據爆破應力集中氣刃作用原則，爆破氣體(ti)沿裂(lie)縫(feng)(feng)進一步擴大(da)(da)貫(guan)通(tong)，拋落巖石。

專業深孔爆破聚能管聚能包由炸、形罩、隔板、殼體、引信和支架等部分組成，其作用及對聚能包威力的影響分述如下。1．炸，炸是聚能管爆破的能源，炸的爆壓越大，聚能彈威力越大；為得到高爆壓，需高爆速、高密度的炸。常用炸有梯恩梯、8321炸等，裝方法有熔鑄，塑裝和壓裝多種。2．型罩，型罩的作用是把炸的爆炸能轉化成罩體材料的射流動能，從而提高其穿透和切割能力。深孔爆破聚能管價格型(xing)罩(zhao)(zhao)(zhao)的材料必須(xu)滿足四點要(yao)求，即可壓縮性(xing)小、密度高、塑性(xing)和延展(zhan)性(xing)好，在形(xing)(xing)(xing)成射流中(zhong)不汽化。大(da)量試驗證(zheng)明，用(yong)(yong)紫銅(tong)制(zhi)作型(xing)罩(zhao)(zhao)(zhao)效果好，其(qi)次為鑄鐵、鋼和陶瓷。型(xing)罩(zhao)(zhao)(zhao)的形(xing)(xing)(xing)狀多種(zhong)多樣，主(zhu)要(yao)有(you)軸對(dui)(dui)(dui)稱(cheng)(cheng)型(xing)，如圓錐形(xing)(xing)(xing)、半球(qiu)形(xing)(xing)(xing)、拋(pao)物線(xian)形(xing)(xing)(xing)和喇(la)叭(ba)形(xing)(xing)(xing)等；面對(dui)(dui)(dui)稱(cheng)(cheng)型(xing)，常見的有(you)用(yong)(yong)于(yu)切(qie)割屬板材的直線(xian)形(xing)(xing)(xing)和用(yong)(yong)于(yu)切(qie)割管材的環(huan)形(xing)(xing)(xing)聚能(neng)罩(zhao)(zhao)(zhao)兩種(zhong)；中(zhong)心(xin)對(dui)(dui)(dui)稱(cheng)(cheng)型(xing)，這種(zhong)球(qiu)形(xing)(xing)(xing)聚能(neng)包(bao)，中(zhong)心(xin)有(you)球(qiu)形(xing)(xing)(xing)空腔和球(qiu)形(xing)(xing)(xing)罩(zhao)(zhao)(zhao)，球(qiu)形(xing)(xing)(xing)罩(zhao)(zhao)(zhao)外(wai)敷設炸，若(ruo)能(neng)在瞬間同時起爆，可在空腔中(zhong)心(xin)點獲得極大(da)的能(neng)量集中(zhong)。在工程中(zhong)常用(yong)(yong)的是軸對(dui)(dui)(dui)稱(cheng)(cheng)型(xing)和面對(dui)(dui)(dui)稱(cheng)(cheng)型(xing)兩類(lei)型(xing)罩(zhao)(zhao)(zhao)。
