專業多向聚能管聚能包由炸、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。多向聚能管廠家型(xing)罩(zhao)(zhao)(zhao)的(de)(de)材(cai)(cai)料必須(xu)滿足(zu)四點要求，即可(ke)(ke)壓縮性(xing)小、密度(du)高、塑性(xing)和延展性(xing)好，在(zai)(zai)形(xing)(xing)成(cheng)射流(liu)中不汽化。大量(liang)試驗證明(ming)，用紫銅(tong)制作型(xing)罩(zhao)(zhao)(zhao)效果好，其(qi)次為鑄鐵(tie)、鋼和陶瓷。型(xing)罩(zhao)(zhao)(zhao)的(de)(de)形(xing)(xing)狀多種多樣，主要有(you)軸對稱(cheng)(cheng)型(xing)，如圓(yuan)錐形(xing)(xing)、半球形(xing)(xing)、拋物線形(xing)(xing)和喇(la)叭形(xing)(xing)等(deng)；面(mian)對稱(cheng)(cheng)型(xing)，常見的(de)(de)有(you)用于切割(ge)屬板材(cai)(cai)的(de)(de)直線形(xing)(xing)和用于切割(ge)管(guan)材(cai)(cai)的(de)(de)環形(xing)(xing)聚能罩(zhao)(zhao)(zhao)兩(liang)種；中心(xin)對稱(cheng)(cheng)型(xing)，這種球形(xing)(xing)聚能包，中心(xin)有(you)球形(xing)(xing)空腔(qiang)和球形(xing)(xing)罩(zhao)(zhao)(zhao)，球形(xing)(xing)罩(zhao)(zhao)(zhao)外敷設炸，若能在(zai)(zai)瞬間同時起爆(bao)，可(ke)(ke)在(zai)(zai)空腔(qiang)中心(xin)點獲得極大的(de)(de)能量(liang)集(ji)中。在(zai)(zai)工程中常用的(de)(de)是軸對稱(cheng)(cheng)型(xing)和面(mian)對稱(cheng)(cheng)型(xing)兩(liang)類(lei)型(xing)罩(zhao)(zhao)(zhao)。
