螺(luo)旋(xuan)風(feng)(feng)(feng)(feng)管(guan)(guan)用(yong)途(tu)：散(san)裝物料輸送：氣力(li)輸送系(xi)統(tong)種(zhong)，鍍鋅螺(luo)旋(xuan)風(feng)(feng)(feng)(feng)管(guan)(guan)廠，一些較(jiao)細些松散(san)的(de)(de)物料顆粒，可使用(yong)螺(luo)旋(xuan)風(feng)(feng)(feng)(feng)管(guan)(guan)輸送，造價低(di)、效果好。安裝螺(luo)旋(xuan)風(feng)(feng)(feng)(feng)管(guan)(guan)的(de)(de)原則(ze)(ze)：為了減(jian)少投(tou)資(zi)扁圓(yuan)螺(luo)旋(xuan)風(feng)(feng)(feng)(feng)管(guan)(guan)，節省空間，降低(di)層高，有些敷(fu)設無坡度要求的(de)(de)管(guan)(guan)道，可以(yi)穿梁敷(fu)設。安裝螺(luo)旋(xuan)風(feng)(feng)(feng)(feng)管(guan)(guan)的(de)(de)原則(ze)(ze)：螺(luo)旋(xuan)風(feng)(feng)(feng)(feng)管(guan)(guan)廠家，邊長或者直徑(jing)大于(yu)1250mm的(de)(de)螺(luo)旋(xuan)風(feng)(feng)(feng)(feng)管(guan)(guan)吊裝時不(bu)能(neng)超(chao)過(guo)兩節，邊長或者直徑(jing)小(xiao)于(yu)1250mm的(de)(de)風(feng)(feng)(feng)(feng)管(guan)(guan)組合吊裝，不(bu)能(neng)超(chao)過(guo)三節。螺(luo)旋(xuan)風(feng)(feng)(feng)(feng)管(guan)(guan)的(de)(de)優勢：管(guan)(guan)路布局優美、立體感強:當管(guan)(guan)道作(zuo)為一種(zhong)建(jian)筑特點而必須(xu)暴露時，優美典(dian)雅(ya)的(de)(de)成(cheng)型法蘭風(feng)(feng)(feng)(feng)管(guan)(guan)將是好的(de)(de)選擇(ze)。壓降低(di):眾所周知，圓(yuan)形(xing)(xing)風(feng)(feng)(feng)(feng)管(guan)(guan)的(de)(de)風(feng)(feng)(feng)(feng)阻比矩形(xing)(xing)風(feng)(feng)(feng)(feng)管(guan)(guan)的(de)(de)風(feng)(feng)(feng)(feng)阻要小(xiao)得多。安全(quan)密(mi)封圈防漏系(xi)統(tong)。

螺(luo)旋風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)的用(yong)(yong)處：散裝(zhuang)物料(liao)輸送。有些工(gong)廠的生產過程中(zhong)(zhong)，需要輸送松散的顆(ke)粒(li)，特別是比重(zhong)不大(da)(da)的如發泡塑料(liao)粒(li)之類的使用(yong)(yong)螺(luo)旋風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)造價低、效果好。同(tong)時接(jie)(jie)縫(feng)均(jun)勻平整(zheng)、咬(yao)口緊密(mi)(mi)、連接(jie)(jie)力(li)強、密(mi)(mi)封性好。安全密(mi)(mi)封圈(quan)防漏系統(tong)。精巧的螺(luo)旋壓制(zhi)楞(leng)(leng)筋工(gong)藝使不銹鋼風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)具有承受(shou)壓力(li)的強度，增加(jia)螺(luo)旋型楞(leng)(leng)筋后。按截面(mian)形狀，風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)可(ke)(ke)分(fen)為圓形風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)，矩形風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)，扁圓風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)等(deng)多種，其(qi)中(zhong)(zhong)圓形風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)阻力(li)小但高度尺(chi)寸(cun)大(da)(da)，制(zhi)作(zuo)復雜。所以(yi)應用(yong)(yong)以(yi)矩形風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)為主。按材質(zhi)，風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)可(ke)(ke)分(fen)為金(jin)屬(shu)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)，復合風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)，高分(fen)子風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)。
