style="text-indent:25px">輸送物料什么情況下對管道有磨損呢：1、物料強(qiáng)度物料強(qiáng)度主要是影響物料在輸送過程中的破碎難度與破碎率，以及由此引起的二次磨損。被輸送物料的平均粒徑隨經(jīng)過彎頭數(shù)量的增加而呈減小的趨勢。這種粒徑減小的趨勢越明顯，相應(yīng)材料對彎頭造成的沖蝕磨損率越高，也就是說，物粒在輸送過程中越容易破碎，則其產(chǎn)生的沖蝕磨損率越高。比如炭黑在輸送過程中，由于彎頭對物料的撞擊會產(chǎn)生一定的破碎。2、物料形狀輸送物料的形狀對管道沖蝕磨損的影響主要體現(xiàn)為其對磨損機(jī)理的影響。粒子沖擊靶材時，粒子與靶材的接觸面積決定了兩者之間作用強(qiáng)度。尖角形粒子對塑性材料表面的沖蝕多為切削型磨損，球形粒子沖蝕所產(chǎn)生的磨損主要表現(xiàn)為塑性變形磨損。</p><p style="text-indent:25px">氣力輸送技術(shù)在糧食行業(yè)的應(yīng)用有哪些問題存在：氣力輸送系統(tǒng)設(shè)備簡單，結(jié)構(gòu)緊湊，占地面積小，現(xiàn)場輸送路線布置靈活，并且整個輸送過程與外界完全隔絕，受到氣候環(huán)境影響比較小，能夠保護(hù)物料不被雜質(zhì)污染，提高輸送質(zhì)量；并且能夠杜絕物料中的粉塵傳到生產(chǎn)車間，改善工作條件，為工人營造一個良好的工作環(huán)境。氣力輸送技術(shù)迄今為止，已經(jīng)有百年的歷史了，氣力輸送被普遍應(yīng)用于化工、電力、建材、煤炭、糧食等行業(yè)。在糧食行業(yè)中，應(yīng)用較多的就是吸送式、壓送式、混合式氣力輸送系統(tǒng)。物料在負(fù)壓下輸送，水分易于蒸發(fā)，因此對水分較高的物料，比壓送式易于輸送。</p><div

style="text-indent:25px">彎管的結(jié)構(gòu)及形狀對磨損的影響：彎管曲率半徑與管道直徑之比(R／D)對磨損的影響很大。傳統(tǒng)理論認(rèn)為物料在彎管中沿外側(cè)內(nèi)壁流動。曲率半徑較大，越趨近于直管，相應(yīng)的磨損和壓力損失也越小。因此，氣力輸送系統(tǒng)較初使用的是長半徑彎管，長半徑彎管的曲率半徑與管道直徑之比(R／D)為8-24。但是，Mason彎管實(shí)驗和實(shí)踐經(jīng)驗表明，物料流經(jīng)彎管時，會在內(nèi)壁外側(cè)和內(nèi)側(cè)彈跳。每個磨損點(diǎn)都說明物料與管壁之間存在強(qiáng)烈的沖擊碰撞造成物料運(yùn)動方向改變。這種沖擊碰撞預(yù)示著物料的破碎和能量的損失。一般情況下，長半徑彎管曲率半徑越大．撞擊越嚴(yán)重．沖擊碰撞點(diǎn)也越多，能量損失就越大，磨損越嚴(yán)重。吉林氣流氣力輸送系統(tǒng)生產(chǎn)</p></p><br
