详细介绍: N型冷凝泵产品介绍 N型冷凝泵系单级单吸悬臂式离心冷凝泵,用来抽送冷凝器中的凝结水和750~3000kw汽轮发电机组抽送凝结水或物理、化学性质类似于水的其他液体之用。目前最广泛的在电厂使用,液体温度不超过80℃。泵进口压力不高于0.6MPa。2.5N3*2冷凝泵叶轮 N型冷凝泵泵主要由泵体、叶轮、轴、悬架、泵盖等部件组成。轴封采用软填料密封。泵的旋转方向从传动方向看,泵为逆时针方向旋转。其中该型号的凝结水泵轴承采用的是悬臂式的托架轴承支撑,当中装有两个滚动的轴承,这样平衡了轴向力,轴承的润滑采用的是油脂润滑。 N型冷凝泵还带有诱导轮,这种结构的凝结水泵结构紧凑、效率高、运行平稳,抗汽蚀性能好。在使用过程中严格按照使用说明进行。[1] 2N型冷凝泵型号性能参数展示 参数 型号 | 流量Q | 扬程H | 转速n | 轴功率Pa | 配带电动机 | 效率η | 必须汽蚀余量 | 叶轮名义直径 | 进出口径 | 泵重 | 功率 | 型号 | m/h | L/s | m | r/min | kw | kw | % | m | mm | mm | kg | 2.5N3×2 | 81012 | 2.222.783.33 | 52.551.550.5 | 2980 | 3.053.423.75 | 5.5 | Y132S1-2YB | 37.54144 | 1.92.02.2 | 148 | 6550 | 53 | 3N6H | 16.52230 | 4.86.18.3 | 686764 | 2930 | 6.798.039.51 | 1115 | | 455055 | 0.750.851.05 | 222 | | | 3N6 | 16.52230 | 4.86.18.3 | 626158 | 2930 | 6.657.408.80 | 11 | | 444955 | 0.750.851.05 | 215 | | | 3N6×2 | 182634 | 57.229.45 | 131128123 | 2950 | 15.2917.4319.98 | 22 | | 425257 | 0.80.951.15 | 首215次222 | | | 3N6×2A | 182634 | 5.007.229.45 | 108105101 | 2950 | 12.914.616.7 | 18.5 | | 415156 | 0.80.951.15 | 首215次205 | | | 4N6H | 30405065 | 8.3311.113.916.7 | 78767265 | 2950 | 13.315.316.920.2 | 22 | | 48545857 | 0.850.9511.15 | 230 | | | 4N6 | 30405060 | 8.3311.113.916.7 | 66646159 | 2950 | 11.4613.1514.4517.21 | 18.522 | | 475357.556 | 0.850.9511.1 | 215 | | | 4N6A | 304050 | 8.3312.513.9 | 403837 | 2930 | 6.677.58.85 | 11 | | 4955.558.5 | 0.911.1 | 175 | | | 4N6×2 | 304550 | 8.3312.513.9 | 110105101 | 2930 | 19.223.824.1 | 30 | | 475457 | 0.951.11.2 | 首220次210 | | | 4N6×2A | 304550 | 8.3312.513.9 | 1009591 | 2950 | 17.421.521.7 | 30 | | 475457 | 0.951.11.2 | 首215次195 | | | 4N6×2H | 304550 | 8.3312.513.9 | 135130123 | 2950 | 232933.5 | 37 | | 486160 | 0.951.151.25 | 首230次220 | | | 6N6 | 406595115 | 1111826.432 | 92918986 | 2950 | 23.329.534.538 | 45 | | 43546771 | 0.80.91.051.2 | 262 | | | 6N6A | 365480100 | 101522.227.8 | 70696866 | 2950 | 16.319.122.826.1 | 30 | | 43536569 | 0.80.911.1 | 225 | | | 6N6B | 366090108 | 1016.72530 | 86858278 | 2950 | 19.625.73033.3 | 37 | | 43546769 | 0.80.91.051.15 | 245 | | | 100N130 | 4252.570 | 11.7014.6019.40 | 143141135 | 2980 | 364046.8 | 55 | Y250M-2 | 444955 | 1.31.52 | 325 | 10050 | 166 | 150N110 | 80100110 | 22.2027.8030.60 | 122116112 | 2980 | 48.352.755 | |
