<span>點(diǎn)擊：<script src="/hyhb/count.php?view=yes&aid=1905&mid=1" type='text/javascript' language="javascript"></script></span></p> </h6> <div id="lm1mc6m" class="wznr"><div> 通風(fēng)管道作為現在我們生活中常見(jiàn)的產(chǎn)品，現在的市場(chǎng)應用非常廣泛，通風(fēng)管道的發(fā)展可以說(shuō)是非常的波折，但是現在我們使用的人群也越來(lái)越多，現在我們在身邊可以經(jīng)常見(jiàn)到通風(fēng)管道，今天煙臺通風(fēng)管道廠(chǎng)家給大家介紹一下通風(fēng)管道的計算。</div> <div> 在進(jìn)行通風(fēng)管道系統的設計計算前，必須首先確定各送(排)風(fēng)點(diǎn)的位置和送(排)風(fēng)量、管道系統和凈化設備的布置、風(fēng)管材料等。設計計算的目的是，確定各管段的管徑(或斷面尺寸)和壓力損失，保證系統內達到要求的風(fēng)量分配，并為風(fēng)機選舉和繪制施工圖提供依據。</div> <div> 進(jìn)行通風(fēng)管道系統水力計算的方法有很多，如等壓損法、假定流速法和當量壓損法等。在一般的通風(fēng)系統中用得*普遍的是等壓法和假定流速法。等壓損法是以單位長(cháng)度風(fēng)管有相等的壓力損失為前提的。在已知總作用壓力的情況下，將總壓力按風(fēng)管長(cháng)度平均分配給風(fēng)管各部分，再根據各部分的風(fēng)量和分配到的作用壓力確定風(fēng)管尺寸。對于大的通風(fēng)系統，可利用等壓損法進(jìn)行支管的壓力平衡。<br /> <img alt="" src="/uploads/allimg/200718/1-200GQ44553961.jpg" style="width: 726px; height: 545px;" /></div> <div> 假定流速法是以風(fēng)管內空氣流速作為控制指標，計算出風(fēng)管的斷面尺寸和壓力損失，再對各環(huán)路的壓力損失進(jìn)行調整，達到平衡。這是目前*常用的計算方法。</div> <div> 選擇合理的空氣流速。風(fēng)管內的風(fēng)速對系統的經(jīng)濟性有較大影響。流速高、風(fēng)管斷面小，材料消耗少，建造費用小;但是，系統壓力損失增大，動(dòng)力消耗增加，有時(shí)還可能加速管道的磨損。流速低，壓力損失小，動(dòng)力消耗少;但是風(fēng)管斷面大，材料和建造費用增加。對除塵系統，流速多低會(huì )造成粉塵沉積，堵塞管道。因此必須進(jìn)行全面的技術(shù)經(jīng)濟比較，確定適當的經(jīng)濟流速。根據經(jīng)驗，對于一般的通風(fēng)系統，其風(fēng)速可按表6-10確定。對于除塵系統，防止粉塵在管道內的沉積所需的低風(fēng)速。對于除塵器后的風(fēng)管，風(fēng)速可適當減小。</div> </div> <p
