一种鼓式离心管道消防排烟风机。该风机为内筒、外筒双层结构。内外筒之间设置导叶支撑内筒、电机和叶轮组的重量。进风口和出风口都在同一条轴线上,进风口起到提高风压作用,叶轮采用离心叶轮。主叶轮由10个后倾的机翼形叶片、曲线形前盘和平板后盘组成,经动、静平衡校正,构成新型鼓式离心管道消防排烟风机。该风机运转平稳,性能稳定,结构紧凑,运输安装方便,克服离心风机和轴流风机风量和风压不能兼顾的缺点。
A Drum Centrifugal Pipe Fire Exhaust Fan. The fan for the inner cylinder, outer cylinder double structure. Between the inner and outer cylinder set guide vane support inner cylinder, motor and impeller weight. Inlet and outlet are in the same axis, the inlet to play the role of increasing pressure, the impeller using centrifugal impeller. The main impeller consists of 10 backward-sloping wing-shaped blades, a curved front plate and a flat rear plate. The main impeller is calibrated by dynamic and static balance to form a new type of drum exhaust pipe fan exhaust fan. The fan running smoothly, stable performance, compact structure, easy transportation and installation, to overcome the centrifugal fan and axial fan air flow and wind pressure can not take into account the shortcomings.
