一、Y5-47型锅炉离心引风机的用途Y5-47型锅炉离心引风机，是为适应燃用各种煤质并有消烟除尘装置的(1～20吨/小时)工业锅炉而联合设计的***高全压效率达90.5%的新系列锅炉引风机.凡进气条件相当,性能又相适者匀可选用,但***高温度不得超过250°C。二、Y5-47型锅炉离心引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，除配20吨锅炉的引风机所需功率较大，而用(D式)联轴器直联传动外，其余均采用三角胶带(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种类除尘器的要求，减少了风机的系列和机号，而且也便于作用单位根据实际情况，自行变换主轴转速来获得所需的较理想的风量、风压。三、Y5-47型锅炉离心引风机的型式（1）引风机制成单吸入，机号有№4、5、6、8、9、12、12.4七种。（2）引风机又可制成左旋转和右施转两种型式。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。“左”“右”均可制成0°、90°、180°三种角度。四、Y5-47型锅炉离心引风机的结构风机由叶轮、机壳、进风口、传动部、调节风让等部分组成。（1）叶轮：有12片，材料为16Mn的后倾平板叶片，焊接于弧锥形前盘与平板形后盘中间，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：用钢板焊接成蜗壳整体。№8以上“左”、“右”旋转通用。（3）进风口：敛散式的进风口制成，采用滚动轴承。(3)型：整体桶式轴承箱，用30°机油油润滑，№8以上有油位标志及温度计，有水冷装置，须加输水管，耗水里量0.5～1m3/h，№6以下有风扇自冷。(1)型：№4～6用两只并列轴承座，润滑有轴承润滑脂或二硫化钼润滑，与机壳之间用两个半圆风扇叶自冷，№8～12.4用两只并列轴承座。（4）调节门：用以调节风量，轴向装在进风口前，转动灵活方便，调节范围大由全开到全闭，№8以上采用花瓣式，№6以下采用蝶阀式，为使调节门正常工作，须保持良好的润滑状态，采用澎涨润滑脂。二、风机性能参数表机号传动方式转速r/min序号全压Pa流量m3/h效率％轴功率kW所需功率kW电动机型号功率kW滑轴代号4C29001234567814511451143213881314123611479902750308034103740407044004730506080858990.5908986801.391.461.531.601.651.711.771.741.912.002.102.192.262.342.432.38Y100L-23T/NF-542-2330012345678187318731863179516971608149112853130350038804250463050005380575080858990.59089868020.42.152.252.352.442.512.602.572.792.943.083.223.343.443.563.52Y112M-24T/NF-542-25C262012345678184418441824176516671759146112654840542060006580716077408320890080858990.5908986803.103.263.453.563.683.813.943.914.254.474.734.885.045.225.405.36Y132S1-25.5T/NF-542-2290012345678226522652246516720501932179515495360601066507300794085809230987080858990.5908986804.214.454.684.855.035.175.355.315.776.106.426.646.897.097.337.23Y132S2-27.5T/NF-542-26C262012345678265826582638255024122275211818248370938010380113901239013400144001541080858990.5908986807.728.148.568.919.229.519.849.7510.5711.1511.7212.2012.6313.0213.4813.35Y160M2-215T/NF-542-32850123456783148314831193011285456782501214891101020011300123901348014570156701676080858990.5908986809.9410.4711.0111.4311.8612.2112.6412.4813.6114.3415.1015.6516.2416.7117.3117.10Y160M2-215T/NF-542-3Y160L-218.58C1820123456782530253025012412228522157201017261378015430170801874020400220502370025360080858990.59089868012.112.813.613.914.414.815.415.216.617.518.619.019.720.321.120.1Y180M-422T/NF-542-4Y180L-42219801234567829912991297128642716256023832050150001680018600204002220024000258002760080858990.59089868015.616.417.417.918.619.219.819.621.422.523.824.525.526.327.126.9Y200L-4309C17401234567829222922289327952648250123242001187802103023280255402779030040232003455080858990.59089868019.120.121.221.922.723.424.224.026.227.529.030.031.131.033.232.9Y225S-437T/NF-542-418201234567831973197306830602903273625402187196402200024350267102907031420337803614080858990.59089868021.6423.0524.2225.1026.0326.9027.8427.5229.6631.6033.2034.4235.6736.8638.2039.70Y225M-445T/NF-542-4Y225M-44512D14501234567836093609357934623275308928732471371004154046000504505490059350638006825080858990.59089868046.448.951.553.555.457.259.258.461.564.868.471.173.575.978.577.5Y280S-47512.4D14501234567838543854382536873491329530602638409404585050760556806059065500704107533080858990.59089868054.757.760.562.965.267.169.569.072.676.680.283.586.589.092.291.6Y280M-490)
