1、+-9-19、9-26型离心通风机一、用途1.1 9-19、9-26型离心通风机，一般用于锻冶炉及高压强制通风，并可广泛用于输送物料、输送空气及无腐蚀性不自燃、不含粘性物质之气体。介质温度一般不超过50(最高不超过80)，介质中所含尘土及硬质颗粒不大于150mg/m3。二、规格与结构特征2.1 风机叶轮直径的分米数即为风机的机号,用阿拉伯数字表示。机号后的字母表示风机的传动方式，传动方式常用的有：“A”式表示与电动机直联传动（叶轮装在电机轴上）。“C”式表示通风机悬臂，皮带轮在轴承外侧传动。“D”式表示通风机悬臂，有支撑、联轴节传动。2.2 风机的旋向分为左、右旋二种，其区分方法是，从传动方向
2、正视叶轮，风机工作时叶轮顺时针旋转的为右旋，反之则为左旋。2.3 风机的出气口方向一般均制成90度，如用户有特殊要求，可在定单上注明（风机的各种出口角度见图1）。以下视图均从电机一端正视图1为便于客户安装、调试，同时供应钢结构的整体支架及减振支架。2.4 风机主要由叶轮、机壳、进风圈、轴承座等部件组成。其中叶轮由曲线型轮盖、叶片、直板轮盘组成，并经静、动平衡校正。轴承座采用滚动轴承用钙基脂润滑。三、风机的性能3.1风机的性能参数可见性能表3.2在性能表各工况点，所需电机功率： 式中：Q-流量（M3/h） N-电机功率（kw） P-全压（mmH2O） -全压效率 m-机械效率“A”式为1，“C”
3、式为0.96 K-电机容量安全系数，2-5kw取K=1.2,大于5kw,取K=1.153.3、所附性能参数表是在一定转速下，标准状态下风机性能参数，如通风机的转速、叶轮直径或气体密度发生变化，则性能参数换算公式如下：换 换算 算公 条式 件项 目D2D2mnnmD2=D2mn=nmD2=D2mnnmD2D2mn=nm压力换算流量换算功率换算效 率四、 安装、调试和运转3.1 安装前应对风机各部件进行全面的检查，叶轮与机壳的旋转方向是否一致，各部联接是否牢固，叶轮转动后有无碰擦，如发现问题应立即给予调整。3.2 安装时注意检查机壳内不得遗留工具和杂物，进出风管道联接时应自然吻合，不得强行联接，绝
4、对不允许将管道的重量加在风机上，并注意风机主轴的水平。3.3 对联轴器或带传动的风机，要检查联轴器或带轮、皮带是否安装可靠。两带轮位置是否在一条中心线上，风机轴与电机轴的同心度是否符合技术要求（径向位移0.1mm，倾斜度0.8/1000）。3.4 风机安装完毕，可进行试运转，在风机启动时必须在无载荷即将进风调节门关闭出风调节稍开的情况下进行（特别是锅炉引风机或高温通风机），在启动过程中应严密注视电流，不得超过电流额定值，如情况良好，逐步将闸门开启到工况点为止。3.5 当风机启动后达到正常转速时，应检查轴承温度是否正常（一般不宜高于80）如发现风机有剧烈的振动，轴承温度迅速上升及异常声响等反常现
5、象时必须紧急停机检查。五、 维护与保养5.1 为了避免由于使用不当而引起的故障和事故发生，延长风机的使用寿命，必须加强风机的维护和检修。5.2 风机进气口前应装过滤装置或除尘器，若进气口不安设备时，必须加防护网，以防止异物吸入打坏叶轮。5.3 定期清除风机及输送管道内部的灰尘污垢。5.4 定期更换润滑脂。5.5 根据下列故障产生原因进行检修：a) 风机剧烈振动1. 基础的刚度不够或不牢固。2. 进气口与叶轮碰擦。3. 部件间或地脚螺栓联接松动。4. 叶轮铆接松动或叶轮变形。5. 进出气口管道安装不良，产生共振。6. 叶片积垢，磨损，叶轮变形，轴弯曲使转子产生不平衡。7. 带轮安装不正，电机轴和
6、风机轴不同心。b) 轴承温度过高1. 润滑脂失效或混入灰尘、砂粒等杂质。2. 轴承座、盖联接螺栓过紧或过松。3. 滚动轴承损坏。c) 电流过大1. 气体的密度过大，使电机超载。2. 电网电压太低或单相断电。六、特 别 警 示6.1 风机安装完毕应使电机可靠接地。6.2 每次启动风机时应严密关闭进气风门，待转动正常后才能开启风门。6.3 风机运行中严禁进入异物。9-19型离心通风机性能表机号No传动方式Type转速speedr/min序号No流量Capacitym3/h全压Pa轴功率Power of ShaftkW电动机Motor外型尺寸长宽高SizeLWHmm规格型号Type功率Power k
