一、风机产品概述1.风机的用途9-19、9－26型高压离心通风机，一般用于锻冶炉及高压强制通风，亦可用于输送物料、空气及无腐蚀、不自燃、不易爆、不易挥发、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物不大于150mg/m3。2.风机的型式1、本风机均为单吸入，通常有№4、4.5、5、5.6、6.3、7.1、8、9、10、11.2、12.5、14、16，共13个机号。2、风机通常制成右旋和左旋两种型式。3、风机的出口位置以机壳的出口角度表示，“左”、“右”风机机壳制成0度、45度、90度、135度、180度、225度。3.风机的结构风机主要由叶轮、机壳、进风口、支架等组成。（1）叶轮：9－19型风机为12片叶片，9－26型风机为16片叶片，均属前弯型。叶轮扩压器外缘最高圆周线速度不得超过140m/s，叶轮成形后，经静、动平衡校正，故运转平稳。（2）机壳：用普通钢板焊接成蜗形壳整体。（3）进风口：做成收敛式流线型的整体结构，用螺栓固定在前盖板上。（4）传动组：由主轴、轴承箱、联轴器等组成。主轴由优质钢制成，轴承箱整体结构。采用滚动轴承，滚动轴承，用润滑脂润滑。二、风机性能参数表9-19高压离心风机参数参数表机号传动方式转速r/min序号全压Pa流量m3/h内效率%内功率%所需功率kw电动机型号功率kw4A290012345673584366536473597350733843253824970111612641410155817047073.575.57675.573.3701.161.331.481.641.801.972.171.51.71.92.12.32.62.6Y90l-22.2Y100L-234.5A290012345674603468446724580444742974112117413971616183920622281250471.2757777.376.273.8702.072.382.682.983.293.634.032.52.93.23.63.94.44.8Y112M-24Y132S1-25.55A290012345675697576857405639551753235080161019322254257628443166348872.776.278.278.577.274.570.53.433.984.505.045.546.176.864.14.85.45.86.47.17.9Y132S2-27.5Y160M1-2115.6A290012345677182727372367109695467096400226227143167361939964448490172.776.278.278.577.274.570.56.057.027.938.889.7610.8812.097.08.19.110.211.212.513.9Y160M1-211Y160L-218.56.3A290012345679149926592199055885785438148322038654509515356906334697872.776.278.278.577.274.570.510.9112.6514.3016.0017.5919.6021.712.514.516.418.420.222.525.1Y160L-218.5Y200L1-2307.1D2900123456711717118681180711596113401093510426461055326454737681449066998872.776.278.278.577.274.570.519.8322.9925.9919.0931.9835.6339.6223.327.030.534.137.541.846.5Y200L2-237Y250M-2558D29001234567150341522915151148771454614021133626594791392321055011649129681428772.776.278.278.577.274.570.536.0241.7547.2152.8358.0864.7171.9542.349.055.462.068.275.984.4Y280S-275Y315S-21108D145012345673620366536473584350733843231329739574616527558256484714472.776.278.278.577.274.570.54.55.225.906.607.268.098.995.56.16.97.78.59.510.6Y132M-47.5Y160L-4159D1450123456745974655463245514453429741014695563365727511829492331017172.776.278.278.577.274.570.58.119.4110.6311.9013.0814.5816.219.511.012.514.015.417.119.0Y160L-415Y180L-42210D1450123456754085941289157405495524449586440794294451094712450139521545576.58081.58178.274.57013.3816.0318.5921.1223.8426.7929.8815.718.821.824.828.031.435.1Y200L-430Y225S-43711.2D145012345677364749174287236692766096246904711158132691538017491196022171376.58081.58178.274.57023.5828.2532.7637.2242.0247.2152.6627.733.238.443.749.355.461.8Y225M-445Y280S-47511.2D960123456731823237321031282996286027055990738887851018211580129781437576.58081.58178.274.5706.848.209.5110.8212.1913.7015.288.09.611.212.714.316.117.9Y180L-615Y209L2-62212.5D1450123456792299390931090688678827878221257715512184472138124316272513018676.58081.58178.274.57040.8448.9256.7264.4672.7681.7591.1847.957.466.675.685.495.9107.0Y280S-475Y315S-411012.5D96012345673975404340093907374135713377832710270122131415616099180421998576.58081.58178.274.57011.8514.2016.4618.7121.1123.7226.4613.916.719.321.924.827.831.1Y200L2-622Y250M-43714D1450123456711668118741177111464109671045798781767021793259163004034163382864240976.58081.58178.274.57071.9786.2299.96113.56128.22144.06160.6984.5101.2117.3133.3150.5169.1188.6Y315M-4132Y355M-422014D960123456750045090504749174709449442491169914428171581988822618253482807876.58081.58178.274.57020.8925.0229.0132.9737.2141.8146.6324.529.434.038.743.749.154.7Y250M-637Y315S-67516D14501234567154251570015563151511448813808130352637732531386864484150995571506330576.58081.58178.274.570140.31168.09194.89221.46249.98280.88313.29164.6197.2228.7259.9293.3329.6367.6Y355M3-4315JS138-441016D960123456765706683662764566180589855751746321538256132968733762378374191276.58081.58178.274.57040.7248.7856.5664.2772.5581.5290.9247.857.266.475.485.195.7106.7Y315S-675Y315L1-61109-26高压离心通风机性能参数机号传动方式转速r/min序号全压Pa流量m3/h内效率%内功率%所需功率kw电动机型号功率kw4A290012345673852382037653684360735023407219823682536270628773044321574.7075.575.77573.872.1703.113.283.463.563.864.064.29)
