中子料位計概述

華科HC-5000型中子料(liao)(liao)(liao)位(wei)計是利(li)用中子在含氫介(jie)質中的散射(she)、慢化原理(li)，測定含氫元素物(wu)料(liao)(liao)(liao)的料(liao)(liao)(liao)罐、塔(ta)(ta)等裝置(zhi)內(nei)(nei)物(wu)料(liao)(liao)(liao)的狀態(tai)和密(mi)度，判定裝置(zhi)內(nei)(nei)物(wu)料(liao)(liao)(liao)為氣(qi)相、泡沫(mo)或(huo)液固(gu)相，并給(gei)(gei)出(chu)物(wu)料(liao)(liao)(liao)密(mi)度的定量(liang)數據，它通過對焦(jiao)(jiao)炭塔(ta)(ta)特(te)定區域內(nei)(nei)物(wu)料(liao)(liao)(liao)含H、C密(mi)度的連(lian)續測量(liang)，給(gei)(gei)出(chu)塔(ta)(ta)內(nei)(nei)全部(bu)物(wu)料(liao)(liao)(liao)狀態(tai)(油氣(qi)、泡沫(mo)、焦(jiao)(jiao)炭或(huo)水)的動態(tai)分布規律(lv)，并在塔(ta)(ta)底(di)注油起(qi)始信號配合下給(gei)(gei)出(chu)泡沫(mo)層(ceng)、焦(jiao)(jiao)炭層(ceng)上沿實時(shi)高度指示(shi)值，為實現焦(jiao)(jiao)化的生產實時(shi)在線控(kong)制提供信息。

中(zhong)子(zi)料位計具有(you)什么特點(dian)

中子的特性

自從人(ren)類發(fa)現(xian)了放射性(xing)物(wu)質，通過核裂變發(fa)現(xian)了很多新物(wu)質，其(qi)中(zhong)(zhong)就有中(zhong)(zhong)子這個微觀(guan)粒子。在(zai)對(dui)中(zhong)(zhong)子的研(yan)究(jiu)中(zhong)(zhong)發(fa)現(xian)，中(zhong)(zhong)子本身不帶電荷呈現(xian)電中(zhong)(zhong)性(xing)，在(zai)運動中(zhong)(zhong)不會受到(dao)電場力的影響(xiang)，具(ju)有較(jiao)強的穿透性(xing)，針狀焦料(liao)位計安裝檢(jian)測，能夠穿透很厚的金屬物(wu)體。

根據中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)能量的(de)(de)不(bu)同，中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)分為快(kuai)(kuai)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)和慢(man)(man)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)，在(zai)自然(ran)核裂變過程中(zhong)(zhong)(zhong)產生的(de)(de)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)是(shi)(shi)自由(you)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)即(ji)快(kuai)(kuai)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)。快(kuai)(kuai)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)運動(dong)中(zhong)(zhong)(zhong)與原(yuan)子(zi)(zi)(zi)(zi)(zi)核的(de)(de)作用主要是(shi)(shi)發生彈(dan)(dan)性散射，當快(kuai)(kuai)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)運動(dong)中(zhong)(zhong)(zhong)碰(peng)到與其自身質(zhi)量相近的(de)(de)氫(qing)質(zhi)子(zi)(zi)(zi)(zi)(zi)時(shi)彈(dan)(dan)性散射損(sun)失(shi)的(de)(de)能量很多。如果(guo)物質(zhi)所(suo)含(han)氫(qing)原(yuan)子(zi)(zi)(zi)(zi)(zi)較多，快(kuai)(kuai)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)在(zai)運動(dong)中(zhong)(zhong)(zhong)發生彈(dan)(dan)性散射的(de)(de)能量損(sun)失(shi)就會變大(da)，快(kuai)(kuai)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)就會變成慢(man)(man)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)。慢(man)(man)中(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)(zi)在(zai)運動(dong)中(zhong)(zhong)(zhong)遇到其他物質(zhi)原(yuan)子(zi)(zi)(zi)(zi)(zi)核的(de)(de)主要作用形式(shi)是(shi)(shi)被吸收。
