真空(kong)(kong)(kong)(kong)(kong)(kong)甩帶爐(lu)(lu)工作原理是什么呢
通(tong)常為防(fang)止真空(kong)(kong)(kong)(kong)(kong)(kong)甩帶爐(lu)(lu)受熱(re)(re)后變(bian)(bian)(bian)形(xing)和(he)(he)(he)密封(feng)材料受熱(re)(re)變(bian)(bian)(bian)質(zhi),爐(lu)(lu)殼一般(ban)用(yong)(yong)水(shui)冷或氣冷降溫。爐(lu)(lu)膛位于密封(feng)爐(lu)(lu)殼內(nei)。根據爐(lu)(lu)子用(yong)(yong)途(tu),爐(lu)(lu)膛內(nei)部裝(zhuang)(zhuang)有不(bu)同(tong)類型(xing)的(de)(de)(de)(de)加熱(re)(re)元(yuan)(yuan)件,如電(dian)(dian)阻、感應(ying)線圈、電(dian)(dian)極(ji)和(he)(he)(he)電(dian)(dian)子槍等。熔煉(lian)金屬的(de)(de)(de)(de)爐(lu)(lu)膛內(nei)裝(zhuang)(zhuang)有坩堝,有的(de)(de)(de)(de)還裝(zhuang)(zhuang)有自(zi)動澆(jiao)注裝(zhuang)(zhuang)置和(he)(he)(he)裝(zhuang)(zhuang)卸料的(de)(de)(de)(de)機械手(shou)等。真空(kong)(kong)(kong)(kong)(kong)(kong)系統主要(yao)由(you)真空(kong)(kong)(kong)(kong)(kong)(kong)泵、真空(kong)(kong)(kong)(kong)(kong)(kong)閥門和(he)(he)(he)真空(kong)(kong)(kong)(kong)(kong)(kong)計等組成(cheng)。
真空(kong)(kong)(kong)(kong)(kong)(kong)甩帶爐(lu)(lu)是利用(yong)(yong)熱(re)(re)媒水(shui)的(de)(de)(de)(de)相變(bian)(bian)(bian)進行(xing)熱(re)(re)交換的(de)(de)(de)(de),燃(ran)料燃(ran)燒(shao)釋放出(chu)的(de)(de)(de)(de)熱(re)(re)量被熱(re)(re)媒水(shui)吸(xi)收,當溫度上(shang)升***某真空(kong)(kong)(kong)(kong)(kong)(kong)狀態(tai)下(xia)的(de)(de)(de)(de)飽(bao)和(he)(he)(he)溫度時,蒸(zheng)發成(cheng)飽(bao)和(he)(he)(he)和(he)(he)(he)蒸(zheng)汽,完成(cheng)一次相變(bian)(bian)(bian)過程。
凝結(jie)水(shui)流進蒸(zheng)發室(shi)繼續吸(xi)熱(re)(re),完成(cheng)相變(bian)(bian)(bian)循(xun)環(huan)。真空(kong)(kong)(kong)(kong)(kong)(kong)甩帶爐(lu)(lu)的(de)(de)(de)(de)下(xia)部結(jie)構(gou)由(you)燃(ran)燒(shao)室(shi)和(he)(he)(he)傳熱(re)(re)管束組成(cheng);上(shang)部為真空(kong)(kong)(kong)(kong)(kong)(kong)室(shi),其中插入(ru)了U型(xing)管熱(re)(re)交換器(qi)。真空(kong)(kong)(kong)(kong)(kong)(kong)室(shi)外接抽(chou)氣單元(yuan)(yuan),使真空(kong)(kong)(kong)(kong)(kong)(kong)室(shi)保(bao)持穩定的(de)(de)(de)(de)真空(kong)(kong)(kong)(kong)(kong)(kong)度,并將真空(kong)(kong)(kong)(kong)(kong)(kong)室(shi)內(nei)不(bu)凝結(jie)氣體抽(chou)出(chu),提高U型(xing)熱(re)(re)交換器(qi)的(de)(de)(de)(de)換熱(re)(re)效(xiao)率。
今天有關真空(kong)(kong)(kong)(kong)(kong)(kong)熔煉(lian)爐(lu)(lu)的(de)(de)(de)(de)原理小編就(jiu)分(fen)享到這了,希望(wang)對大(da)家(jia)有所幫助(zhu)。如有需要(yao)歡迎電(dian)(dian)話咨詢聯系。
