YaHei";">關于離心風機,對離心通風機的噪聲聲級、常見壓力分類,以及其單進風和雙進風的區別和適用情況,進行講解。</span></p><p><span style="font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei";">1.離心風機的噪聲聲級<br/></span></p><p><span style="font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei";">離心風機,其噪聲的聲級,在相關因素上,主要是有風機結構、風機工作狀態這兩個。而且,其的工作狀態,是由全壓和風量這兩個來決定的。因此,不同型號或不同系列的離心通風機,在聲級上肯定是不一樣。而且,即便是同一型號,如果處于不同工況,那么其聲級,也是不一樣的。</span></p><p><span style="font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei";">離心網機嗓聲的控制方法,一般的,是在風機進出風口上安裝消聲器,如果要求比較髙的話,還可以使用消聲隔聲箱,同時,可以在風機與地基之間安裝減震器,從而,來得到好的障噪效果。<br/></span></p><p><span style="font-size: 16px;

style="font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei";">離心風機中，在壓力上，其的常見，主要是有以下這三個：</span></p><p><span style="font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei";">低壓離心風機:壓力是在1000Pa以下</span></p><p><span style="font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei";">中壓離心風機:壓力是為1000-3000Pa</span></p><p><span style="font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei";"><a href='http://www.7yaya.com/product/597.html' target='_blank' class='key_tag'><font color=#2086ee><strong>高壓離心風機</strong></font></a>:壓力是在3000Pa以上</span></p><p><span style="font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei";">3.離心通風機單進風和雙進風的區別和適用情況<br/></span></p><p><span style="font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei";">離心同機中的單進風,是指風機中只有一個進風口和一個出風口,因此,其壓力是比較高的,可用在除塵車間中,以及油煙系統中。而雙兩個進風口,一個出風口,所以，其風量是比較大的,可用于風量要求較大的場合中。</span></p><p><br/></p></div> <h3 class="tag">本文網址：http://www.7yaya.com/news/509.html </h3>
