1、用途 G5-51锅炉鼓风机和Y5-51锅炉离心引风机,适用于火力发电厂中2~670t/h蒸汽锅炉的送引风系统,也满足了流化床炉的高压头性能参数的要求。该系列风机也可用于除尘,矿井通风及一般通风系统。
送风机输送的为空气,引风机输送的为烟气或含杂质颗粒的气体。含杂质深度小于200mg/m3时可用4年以上。如含杂质大也可使用,但使用寿命将缩短。送、引风机***高使用温度不得超过250℃。
2、形式
1)送风机、引风机制成单吸入形式。机号№8~29.5各20个机号共40种规格。
2)每种风机又可制成左旋转或右旋转两种形式。
3)风机出风口位置,以机壳的出口角度表示。 查看风机旋向与出口角度示意图
4)风机传动方式为D式(即悬臂结构),电动机与风机连接均采用弹性联轴器,直联传动。
5)产品全称举例如下:
G5-51-1№18D右90度
Y5-51-1№18D左0度
其中:G、Y分别表示锅炉送风机与锅炉引风机,5为***高效率点的压力系数10倍化整,51为比转速,1为次设计,№18表示叶轮直径1800mm。
4)高强度耐磨叶轮。叶轮采用后向单板叶片,减少气流冲击,稳定性好,电动机不易过载,大大延长了风机使用寿命。该型风机压力系数高、周速低、噪声小,因而实用性好。
5)防漏油轴承箱。采用搭接式甩油环将高速旋转的轴承带起的油甩至轴承箱内壁流回油池;半开式铝质油封除方便检修和防止摩擦事故外,可沿轴向增大阻力将部分稀油截回油池;外侧压盘根是将少量的稀油挡住;轴承箱上部设有通气塞减小了轴承箱里的微正压,保证不漏油,防尘性能好。
7)该风机为整体或分体组装式。该系列风机16D以下的传动组、联轴器罩、电动机出厂前组装在一个完整的底座上;机壳、进风口和调节门为另一个组件,小型号风机出厂时组装为两个组件,大型号的分解组装为多个组件,以便运输及安装。
8)该风机为悬臂结构、布置方便,电动机直联传动,均匀传递转矩,减小振动使风机运行可靠。
9)该风机安装及检修方便。该风机有两部分完整的底座机宙及传动组,机壳有中分面或立分面,拆装特别方便,转子可垂直吊出,如只更换叶轮时也可轴向拆装。
4、性能与选择
1)风机的性能。风机的性能以风机的流量、全压、主轴转速,轴功率和效率等参数表示。选择曲线与性能表中所给出的性能。送风机性能:t=20℃、大气压力Pa=101325Pa、气体密度ρ=1.2kg/m3空气介质计算。
引风机的性能按气体温度t=200℃、大气压力Pa=101325Pa、气体密度ρ=0.745kg/m3时的空气介质计算。
选择曲线与性能表中性能均指调节叶片为全开0度时的性能。订货时以性能表为准。风机性能试验全压值的偏差不超过设计全压值的±5%。
如风机使用条件与上述不符时,性能应按相关公式换算。
