圆形管道离心式通风机 1. 概述 Instruction 圆形管道风机系列是结合国内外先进技术而设计的新型风机 , 进风口和出风口外形尺寸相同 , 风机直接与风管连接, 能够极大地节省管道设计及安装费用；新型设计的机壳以及依照空气动力学设计的叶轮，能够减少振动和噪音。适用于酒店、宾馆、高级会场、超市、贮藏室、洗手间等地方的送风、排风、回风、补风和过滤。 Circular duct fans series are combined with domestic and foreign advanced technology on design. The sizes of inlet duct and outlet duct are the same. Connected the fan and piping directly could save design and install cost on the piping and please Fig.1.Special housing could reduce noise and vibration, best design on the impeller base on aerodynamics. Design for blow, exhaust, circle, renew and filtration could be used in hotel, marketplace, gymnasium, supermarket, store room and most of public place. 单个圆形管道风机的重量均不超过 9 公斤，只需一个人就能轻易地移动圆形管道风机，方便安装。 No appliance of this range weighs more than 9 kg, so that one person alone can conveniently move and install them.
2.产品结构Structure 圆形管道风机系列主要由外壳、叶轮、电机、支架和接线盒组成。 Consist of housing, impeller, motor, bracket and connection box. * 外壳：采用优质热镀锌钢板制成，具有优良的耐大气腐蚀性能 ；采用ABS材料独家外观设计（已受国家外观专利保护），具有高韧度高延展性，轻便美观等优点。进风口设计成符合空气动力学的形状，便于气流进入叶轮。进风口和出风口外形尺寸相同，以便于安装。进风盖和出风盖采用螺钉连接，便于维修与清洁。 1) Housing: Galvanize steel sheet material could be able to bear corrosive. And ABS housing with good flexibility, light to use and the characteristics of beautiful. The best design for inlet is based on aerodynamics so that the airflow can easily enter into impeller. Same size for the inlet and outlet can install conveniently. Bolt connection for inlet cover and outlet cover ensure easy maintenances and cleanness. * 叶轮： 均设计成后向式叶轮，在正常运转的情况下，均能与外壳良好配合，风量大 , 效率高 , 噪音低。叶轮与外转子电机构成整体 , 成为叶轮轮毂的驱动电机被气流高效地冷却，可以延长风机寿命。 2 ) Impeller: All of Impeller are designed backward curve with big flow, high efficiency, lower noise. The impeller is integrated into the external rotor motor so that the motor is equal to a wheel hub. So the motor can be cooled by the airflow efficiently to prolong life. * 电机：采用外转子单相异步电动机，通过 CE 认证、 CCC 认证、 UL 认证。该电机的特点是叶轮直接压装在电机外壳上，由电机外壳旋转直接驱动，机电一体，结构合理，体积小，节省安装空间；重量轻，运行平稳，效率高，寿命长。 3 ) Motor: External rotor single-phase asynchronous motor received CE ， CCC ， UL certification. The characteristics of the motor are: The impeller is installed on the external casing of the motor directly and is drived by motor directly. The impeller and the motor are combined to a whole with small volume and litter install space; Mini size, reliable performance, high efficiency and long life. * 接线盒：采用加有阻燃成分的 ABS 材料制成，防火性能较好。安装在整机外表面，接线、拆装非常方便。 4 ) Connection Box: Made of ABS contained material which can prevent burning. It is installed outward apperance and connecting wire and packing is very convenient. *调速器：公司最新研发的一款风机调速器，通过旋转按钮，可调节风机0速度至全速间的任一个速度。 5 ) Variable Speed Controller: This's our manufactory latest product. You can get any speed for 0-full by turning the round button on the controller.
