Y5-47离心通风机一、风机的用途 Y5一47型锅炉离心引风机，是为适应燃用各种煤质并配有消烟除尘装置的工业锅炉(1一20吨/小时)而联合设计的最高全压效率达87.4%的新系列锅炉引风机，凡进气条件相当，性能又相适应者均可选用，但最高温度不得超过250℃。在引风机前，必须加除尘装置，以保证进入风机的烟气中含尘量低，除尘效率不得低于85%。二、风机的特点 当前工业锅炉系列较多，燃用煤质优劣悬殊，配用的除尘器阻力不一，所需的引风机的风量、风压差异较大。为适应上述情况，考虑到风机的经济性，除(D式)联轴器直联传动外，还采用三角胶带(C式)传动，不仅能以一个机号采用不同转速来满足同一吨位锅炉配置各类除尘器的要求，减少了风机的系列和机号，而且也便于使用单位，根据实际情况，自行变换主转速来获得所需的较理想的风量、风压。三、风机的型式 1、引风机制成单吸入，机号有No 4、5、6、8、9、10、11、12、12.4九种。 2、引风机又可制成顺旋转或逆旋转两种形式，从传动部正视风机，如叶轮顺时针旋转称为右旋转，以右表示:逆时针旋转，称为左旋转，以左表示。 3、风机的出风口位置以机壳的出风口角度表示。右、左均可制成0, 90, 180三种角度。四、主要组成部分的结构和特性 风机由叶轮、机壳、进风口、传动部等部分组成，并配带调节门。 1、叶轮:有12片，材料为16Mn后倾平板叶片，焊接于弧锥形轮盖与平板形轮盘中间，经静、动平衡校正，因此运转平稳，有较高的强度和耐磨性，使用寿命较长。2、机壳:用钢板焊接成蜗形壳整体。No8以上右、左转通用。3、进风口:敛散式的进风口制成整体结构，用螺栓固定在机壳入口侧。4、传动组:主轴由优质钢制成，采用滚珠轴承、二只并列的轴承座，用轴承润滑脂或二硫化钥润滑脂润滑和风叶自冷:结构简单。5、调节门:调节门是风机的附件，用以调节风机的流量。调节门叶片No4-9为蝶板形No 8以上为花瓣形，轴向安装在进风口面前，由于采用了外部传动的结构，传动灵活方便。调节范围由90(全闭)到0(全开)。调节门的扳把位置从进风口方向看，在右狈叮。对右旋转风机扳把从下往上推是由全闭到全开方向:对于左旋风机，扳把从上往下拉是由全闭到全开方向。为使调节门各部正常工作，必侧良好的润滑，润滑脂采用高温(260℃)膨润土脂，在风机高温运转时仍能保证润滑作用。★Y5-47锅炉引风机主要性能参数表机号主轴转速
