椭圆风管机
椭圆风管的主要优点为：（The major adventage of the oval tuber pipe is）
全自动机械化工厂生产，产品洁净无灰尘 The full-automatic mechanical chemical plant produces, the products have no dust clean
断面湿周小，风管率极低，仅0.02% Wet Zhou Xiao of section ,the leaking out rate of the tuber pipe is extremely low
锁缝严密，管内锁缝隙平滑且无泄露；锁缝具有加强筋的作用 The lock is sewn tightly,lock the chink levelly and smoothly and not let out when in charge of,lock and sew have function which strengthens the muscle
结构强度高，刚性好，避免二次噪音产生 The structure is highy in intensity,rigidity is good,prevent two noises from producting
有较长的连续长度（一般管长为4-8M），风管尺寸一致性好，安装简便 Have lopnger continuous length(It is in change of longs to be 4-8M generally),size kind tuber pipe have It is simple and convenient to install
占有空间高度小，适应层高不足的建筑空间的通风风管。 Occupy space to be highly little ,adapt to layers of high insufficient building ventiulation tuber pipe of space
椭圆风管与矩形风管的比较
一 阻力比较
当截面积相同时，矩形风管的周长比椭圆风管周长要大20%.意味着所需材料增多，投资成本增加。场) |
