| 风管按照风管截面形状的不同，分为三种：矩形风管、圆形风管及椭圆形风管。国内目前大多使用的是矩形风管及圆形风管。相较于前两种风管，椭圆形风管有漏风率低，结构强度高，刚性好，占用空间高度小等优点，椭圆形风管的使用也逐渐增加。椭圆形风管的制作，是经过椭圆风管机一次性扩张成型至客户所需的椭圆风管的标准尺寸，具有成型好，效率高，操作简聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 便等优点，是通风管道生产中不可缺少的设备。螺旋风管换成椭圆风管前工序之用·
原理是：先将圆风管逐步压成椭圆形，然后进入椭圆风管机，扩张成型。 According to the different cross-section shapes of air ducts, air ducts can be divided into three types: rectangular, circular and elliptical. At present, most of the domestic air ducts are rectangular and circular. Compared with the first two kinds of air ducts, elliptical air ducts have the advantages of low air leakage rate, high structural strength, good rigidity, small space occupation height, etc., and the use of elliptical air ducts has gradually increased. The manufacture of oval air duct is the standard size of oval air duct which is formed by one-time expansion of oval air duct fan to customers' needs. It has the advantages of good forming, high efficiency, easy operation and so on. It is an indispensable equipment in the production of ventilation duct. The principle of the procedure before replacing the spiral air duct with the elliptical air duct is: firstly, press the circular air duct into the elliptical one gradually, then enter the elliptical air duct fan, and expand and form |
