北京ISG50-250B管道泵中的離心泵是按照原理為它命名的，先大哥比喻解釋一下離心的含義吧，離心其實是物體慣性的表現(xiàn)，比如雨傘上的水滴，當雨傘緩慢轉(zhuǎn)動時，水滴會跟隨雨傘轉(zhuǎn)動，這是因為雨傘與水滴的摩擦力做為給水滴的向心力使然。但是如果雨傘轉(zhuǎn)動加快，這個摩擦力不足以使水滴在做圓周運動，那么水滴將脫離雨傘向外緣運動，就象用一根繩子拉著石塊做圓周運動，如果速度太快，繩子將會斷開，石塊將會飛出.這個就是所謂的北京ISG50-250B管道泵就是根據(jù)這個原理設計的，高速旋轉(zhuǎn)的葉輪葉片帶動水轉(zhuǎn)動，將水甩出,從而達到輸送的目的。類似于這樣命名的還很多，如：隔膜泵、螺桿泵、轉(zhuǎn)子泵、齒輪泵、真空泵、ISG管道離心泵主要用途　供輸送清水及物理化學性質(zhì)類似于清水的其他液體之用，適用于工業(yè)和城市給排水、高層建筑增壓送水、園林噴灌、消防增壓、遠距離輸送、暖通制冷循環(huán)、浴室等冷暖水循環(huán)增壓及設備配套，使用溫度T<80℃。用于消防的型號參數(shù)對照型號進口徑出口徑流量流量揚程電壓轉(zhuǎn)速功率必須汽(m3/h)(L/s)(m)V(kW)蝕余量ISG20-16020202.50.732220/38029001.12.3ISG25-125252541.120220/38029000.752.3ISG25-125A25253.6116220/38029000.552.3ISG25-16252541.132220/38029001.52.3ISG25-160A25253.7128220/38029001.12.3ISG32-12532324.51.320220/38029000.752.3ISG32-16032324.51.332220/38029001.52.3ISG32-160A323241.125220/38029001.12.3ISG32-20032324.51.350220/380290032.3ISG32-200A323241.140220/38029002.22.3ISG32-100I32326.31.813220/38029000.752.3ISG32-125I32326.31.820220/38029001.12.3ISG32-160I32326.31.832220/38029002.22.3ISG32-200I32326.31.850220/380290042.3ISG40-10040406.31.813220/38029000.752.3ISG40-100A40405.61.610220/38029000.372.3ISG40-12540406.31.820220/38029001.12.3ISG40-125A40405.61.616220/38029000.752.3ISG40-16040406.31.832220/38029002.22.3ISG40-160A40405.91.628220/38029001.52.3ISG40-160B40405.21.424220/38029001.12.3ISG40-20040406.31.850220/380290042.3ISG40-200A40405.91.644220/380290032.3ISG40-200B40405.51.538220/38029002.22.3ISG40-25040406.31.880220/38029007.52.3ISG40-250A40405.91.670220/38029005.52.3ISG40-250B40405.51.560220/380290042.3ISG40-100I404012.53.513220/38029001.12.3ISG40-100IA404011.23.110220/38029000.752.3ISG40-125I404012.53.520220/38029001.52.3ISG40-125IA404011.23.117220/38029001.12.3ISG40-160I404012.53.532220/380290032.3ISG40-160IA404011.73.328220/38029002.22.3ISG40-160IB404010.52.923220/38029001.52.3ISG40-200I404012.53.550220/38029005.52.3ISG40-200IA404011.73.340220/380290042.3ISG40-200IB404010.52.935220/380290032.3ISG40-250I404012.53.580220/3802900112.3ISG40-250IA404011.73.370220/38029007.52.3ISG40-250IB404010.8360220/38029007.52.3ISG50-100505012.53.513220/38029001.12.3ISG50-100A505011.23.110220/38029000.752.3ISG50-125505012.53.520220/38029001.52.3ISG50-125A505011.23.117220/38029001.12.3ISG50-160505012.53.532220/380290032.3ISG50-160A505011.73.328220/38029002.22.3ISG50-160B505010.52.923220/38029001.52.3ISG50-200505012.53.550220/38029005.52.3ISG50-200A505011.73.345220/380290042.3ISG50-200B505010.52.935220/380290032.3ISG50-250505012.53.580220/3802900112.3ISG50-250A505011.73.370220/38029007.52.3ISG50-250B505010.8360220/38029007.52.3ISG50-250C5050102.852220/38029005.52.3ISG50-100I5050256.913220/38029001.52.3ISG50-100IA505022.46.210220/38029001.12.3ISG50-125I5050256.920220/380290032.3ISG50-125IA505022.46.216220/38029002.22.3ISG50-160I5050256.932220/380290042.3ISG50-160IA505023.46.528220/380290042.3ISG50-160IB505021.6624220/380290032.3ISG50-200I5050256.950220/38029007.52.3ISG50-200IA505023.46.544220/38029007.52.3ISG50-200IB505021.6637220/38029005.52.3ISG50-25015050256.980220/3802900152.3ISG50-250IA505023.46.570220/3802900112.3ISG50-250IB505021.6660220/3802900112.3ISG50-315I5050256.9125220/3802900302.3ISG50-315IA505023.46.5110220/3802900222.3ISG50-315IB505021.6693220/380290018.52.3ISG65-1006565256.913220/38029001.52.3ISG65-100A656522.46.210220/38029001.12.3ISG65-1256565256.920220/380290032.3ISG65-125A656522.46.216220/38029002.22.3ISG65-166565256.932220/380290042.3ISG65-160A656523.46.528220/380290042.3ISG65-160B656521.6624220/380290032.3ISG65-2006565256.950220/38029007.52.3ISG65-200A656523.46.544220/38029007.52.3ISG65-200B656521.6637220/38029005.52.3ISG65-256565256.980220/3802900152.3ISG65-250A656523.46.570220/3802900112.3ISG65-250B656521.6660220/3802900112.3ISG65-3156565256.9125220/3802900302.3ISG65-315A656523.46.5110220/3802900222.3ISG65-315B656521.6693220/380290018.52.3ISG65-315C656520.65.785220/380290018.52.3ISG65-100I65655013.913220/380290032.3ISG65-100IA656544.812.410220/38029002.22.3ISG65-125I65655013.920220/38029005.52.3ISG65-125IA656544.812.416220/380290042.3ISG65-160I65655013.932220/38029007.52.3ISG65-160IA656546.81328220/38029007.52.3ISG65-160IB656543.21224220/38029005.52.3ISG65-200I65655013.950220/3802900152.3ISG65-200IA656546.81344220/3802900112.3ISG65-200IB65654311.937220/38029007.52.3ISG65-250I65655013.980220/3802900222.3ISG65-250IA656546.81370220/380290018.52.3ISG65-250IB65654311.960220/3802900152.3ISG65-315I65655013.9125220/3802900372.3ISG65-315IA656545.812.7105220/3802900302.3ISG65-315IB65654311.993220/3802900302.3ISG65-315IC65654111.485220/3802900222.3ISG80-10080805013.913220/380290032.3ISG80-100A808044.812.410220/38029002.22.3ISG80-12580805013.920220/38029005.52.3ISG80-125A808044.812.416220/380290042.3ISG80-1680805013.93238029007.52.3ISG80-160A808046.8132838029007.52.3ISG80-160B808043.2122438029005.52.3ISG80-20080805013.9503802900152.3ISG80-200A808046.813443802900112.3ISG80-200B80804311.93738029007.52.3ISG80-25080805013.9803802900222.3ISG80-250A808046.81370380290018.52.3ISG80
