支吊架不得正規螺旋風管安裝在風口、閥門檢查孔處,以免妨礙操作。吊架不得直接吊在法蘭上。保溫風管不能直接與支螺旋風管安裝吊(diao)(diao)架(jia)接(jie)觸,應墊上(shang)堅固(gu)的隔熱材料,其厚度與保(bao)溫風管(guan)厚度相(xiang)同,防(fang)止產(chan)生“冷橋”。聚氯吞烯風管(guan)也與鋼板風管(guan)一樣采用支(zhi)、吊(diao)(diao)托架(jia),但一般以(yi)吊(diao)(diao)架(jia)為主,支(zhi)架(jia)間距按下表的要求制作安裝。
等離子體正規螺旋風管凈化法:近市場上有報道出現等離子體油煙凈化設備的使用。其原理是利用高壓靜電法的同時, 在靜螺旋風管安裝電場的(de)(de)前端設置等離子(zi)場,利用(yong)其高(gao)能量(liang)所激(ji)發的(de)(de)大量(liang)活性自由基對油霧粒子(zi)進行降(jiang)解,使其粘度下降(jiang),易于收集。在產生等離子(zi)體的(de)(de)同時,高(gao)頻放電產生的(de)(de)瞬時高(gao)能量(liang),能打(da)開某些有害氣(qi)體的(de)(de)化學鍵而成(cheng)為單(dan)質原子(zi)或無害分(fen)子(zi)。據報(bao)道該技術(shu),去除率高(gao),處理后氣(qi)體無異(yi)味,維護(hu)方便,但(dan)投資成(cheng)本昂(ang)貴,技術(shu)還(huan)不夠成(cheng)熟。
在目前的社正規螺旋風管會發展的大潮中,新的行業已經是不斷涌現,而一些舊的行而漸漸式微直到銷聲匿跡,從業者螺旋風管安裝也不(bu)(bu)得不(bu)(bu)重新(xin)尋(xun)找其他行(xing)業的(de)發(fa)展(zhan)機會。白(bai)鐵加(jia)工卻不(bu)(bu)同,它在(zai)時代發(fa)展(zhan)的(de)潮流中留存了下來并獲得一定的(de)發(fa)展(zhan),這就(jiu)明(ming)顯的(de)表明(ming)了一個道理,那就(jiu)是黑(hei)白(bai)鐵加(jia)工行(xing)業在(zai)現(xian)代社會還(huan)有市(shi)場,或者就(jiu)是該行(xing)業在(zai)發(fa)展(zhan)中轉型成功(gong),并已經找到了更為廣(guang)闊(kuo)的(de)新(xin)市(shi)場。
