使用范围和性能特点：
FDFY-G系列防堵关风器广泛使用于粮食、饲料、食品加工厂及化工、医药、烟草、冶金、水泥等部门。对于在正压、负压状态下的粉粒状、片状及纤维物料起着连续排卸和密气的作用，是通风除尘和气力输送风网中的重要设备。JD系列防堵关风器具有结构紧凑实用，密气性强。 轴承外置、解决轴承串灰问题，处长轴承使用使用。 叶片上端采用耐磨材料，叶片磨损后可调节或更换配件，维修方便。
Application Scope and Performance Characteristics:
FDFY-G series anti-blocking airlock is widely applied to large, small and medium-sized food and feedprocessing factories, chemical, medicine, tobacco, metallurgy and cement industries. It can continuously discharge the powdery, granular, flaky and fiber materials with its good airtightness function under positive pressure and negative pressure. It is an important equipment in the exhaust system of ventilation, dust removal, pneumatic conveying.主要技术参数（Main Technical Data):
关风器排料量G计量公式：G：0.06V.N.Y.R.K（吨/小时）
V-关风器容量（升/转） N-关风器转速（转/分）
Y-关风器容量积效率：颗粒状物料r-0.8；粉状物料r=0.5~0.6
R-物料容量（吨/米3）K-修正系数，一般取0.7~0.8
Material Discharging Amount of Airlock Is Calculated According to the Following Formula:
G:0.06V.N.Y.R.K(t/h)
V-volume of airlock(l/r) N-Rotating speed of airlock(r/min)
Y-volumetric efficiency of airlock:grain material r-0.8;powder material=0.5~0.6
R-Matirial capacity (t/m3) K-Reduction coefficient, generally0.7~0.8本公司可根据用户的需求定制各种材质、规格、型号及特殊配置的关风器
