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)(xing)罩(zhao)的(de)(de)(de)(de)材(cai)料必須滿足四點要求，即可壓(ya)縮性(xing)小(xiao)、密度高(gao)、塑性(xing)和延展性(xing)好(hao)，在形(xing)(xing)(xing)成射流中不汽化。大量(liang)試驗證明(ming)，用(yong)紫銅制(zhi)作型(xing)(xing)罩(zhao)效(xiao)果好(hao)，其次為鑄鐵、鋼(gang)和陶瓷(ci)。型(xing)(xing)罩(zhao)的(de)(de)(de)(de)形(xing)(xing)(xing)狀多(duo)種(zhong)(zhong)多(duo)樣，主要有軸對(dui)稱(cheng)型(xing)(xing)，如圓錐形(xing)(xing)(xing)、半球(qiu)形(xing)(xing)(xing)、拋物線(xian)形(xing)(xing)(xing)和喇叭形(xing)(xing)(xing)等；面對(dui)稱(cheng)型(xing)(xing)，常(chang)見的(de)(de)(de)(de)有用(yong)于切割(ge)屬板材(cai)的(de)(de)(de)(de)直線(xian)形(xing)(xing)(xing)和用(yong)于切割(ge)管材(cai)的(de)(de)(de)(de)環形(xing)(xing)(xing)聚(ju)能罩(zhao)兩種(zhong)(zhong)；中心對(dui)稱(cheng)型(xing)(xing)，這(zhe)種(zhong)(zhong)球(qiu)形(xing)(xing)(xing)聚(ju)能包，中心有球(qiu)形(xing)(xing)(xing)空(kong)腔和球(qiu)形(xing)(xing)(xing)罩(zhao)，球(qiu)形(xing)(xing)(xing)罩(zhao)外(wai)敷設炸(zha)，若(ruo)能在瞬(shun)間同時起爆(bao)，可在空(kong)腔中心點獲得極大的(de)(de)(de)(de)能量(liang)集(ji)中。在工程(cheng)中常(chang)用(yong)的(de)(de)(de)(de)是(shi)軸對(dui)稱(cheng)型(xing)(xing)和面對(dui)稱(cheng)型(xing)(xing)兩類型(xing)(xing)罩(zhao)。
