泵 水 力 模 型以關醒凡教授為首的水力模型試驗研究小組，從2000年起堅持試驗8年多，研制成功系列軸流泵模型、貫流泵模型，雙向泵模型、系列可調節(jié)葉輪導葉式斜流泵模型。系列軸流泵模型（含雙向泵模型）參加水力部南水北調工程天津試驗臺同臺試驗，性能指標排在前列。貫流泵模型經(jīng)河海大學試驗臺復試，裝置效率達到79%。斜流泵模型（JHM-450），在天津試驗臺進行裝置試驗（引嫩入白工程五家子泵站），最優(yōu)裝置效率達83.4%。這些模型已與上海KSB、日立泵制造（無錫）、高郵水泵廠、長沙水泵廠、合肥三益等合作，用于南水北調工程萬年閘站、臺兒莊站、劉山站、江都四站；南水北調支線大套站、通榆河北延送水工程、灌南河北泵站、后善河南泵站。雙向泵用于廣東黃麻涌、北窖、五沙三村泵站。斜流泵用于上海陳行泵站、廣西安平泵站、引嫩入白工程五家子泵站等。本模型也在中部四省泵站改造工程中得到應用。一、貫流泵裝置模型性能參數(shù)1、JGZM-3貫流泵水泵模型裝置性能參數(shù)表 （河海臺，D=300mm, n=1450r/min）葉片安放角流量Q（L/S）揚程H（m）效率（%）汽蝕比轉速C比轉速ns+4433.03.1077.9010291490+2399.53.0978.56112614350367.73.0378.6311241397-2342.02.8279.0511051422-4308.32.8578.53104213402、JGZM-4貫流泵水泵模型裝置性能參數(shù)表 （江大臺，D=300mm, n=1450r/min）葉片安放角流量Q（L/S）揚程H（m）效率（%）汽蝕比轉速C比轉速ns+4438.504.6880.2510051174+2416.874.5679.66108311520391.194.2379.4611001122-2373.963.9678.8310891095-4353.743.7278.7810241100二、江蘇大學系列軸流泵模參數(shù)表（8個泵段模型）模型代號葉片角度(o)流 量 (l/s)揚 程(m)效 率(%)平均效率(%)汽蝕比轉速（C）比轉速ns名義比轉速ns南水北調用例天津8號TJ04ZL08+4380.5910.05385.8585.08856578550+2363.359.79785.849015760347.179.51885.19956575-2332.659.16284.511007580-4326.888.36184.021077615天津3號TJ04ZL03+4401.699.30884.8284.41940629600+2376.619.28884.969716100362.848.78884.711004625-2351.588.36384.501006638-4329.068.25683.061031623天津2號TJ04ZL02+4412.867.68084.6385.12931737700江都四站+2386.487.52785.159837240367.507.26285.601010725-2358.306.73785.221045758-4337.126.54984.991162751天津20號TJ04ZL20+4392.647.1386.0585.44863760800萬年閘+2381.476.67885.589267960365.806.43085.291008793-2345.326.40885.201089772-4328.895.99085.061398793天津19號TJ04ZL19+4414.786.29786.1685.50940857850臺兒莊+2396.296.18985.919778540374.056.21885.441019822-2357.175.78385.131157848-4341.725.64384.871258845天津6號TJ04ZL06+4444.225.21886.3585.6291810221000劉山站+2416.185.18785.849359930401.644.8085.7210021034-2377.204.80485.4610231002-4357.314.60485.2711321007-6332.174.59985.101154971天津7號TJ04ZL07 +4397.234.18383.7783.4295711401250+2384.343.68083.89112612350370.333.28383.6912781321-2326.173.27883.4813711241-4282.043.57182.2812941082天津10號TJ04ZL10B（雙向泵）+4473.623.17974.2975.1915301600+2437.183.14475.3914820414.032.65575.331637-2378.552.63975.641573-4354.642.25175.291715三、導葉式混流泵模型試驗資料（泵段）系列導葉式混流泵（斜流泵）模型試驗結果（n=1450r/min）JHM-350A角度流量Q（m3/s）揚程H（m）功率P（kW）效率（%）比轉數(shù)ns0.36519.384.10347JHM-350角度流量Q（m3/s）揚程H（m）功率P（kW）效率（%）比轉數(shù)ns-40395.8617.9782.45382-20371.4017.9283.4437000345.2617.2784.133672033.9015.2484.8839640294.2615.1784.15373JHM-400角度流量Q（m3/s）揚程H（m）功率P（kW）效率（%）比轉數(shù)ns-400.339914.3755.3986.47418-200.3826314.4462.1487.18442000.4002116.4573.6487.67410200.4395816.7282.1587.72424400.4771117.1792.1587.16433600.4978318.15101.4187.33425JHM-450角度流量Q（m3/s）揚程H（m）功率P（kW）效率（%）比轉數(shù)ns-400.32712.646.686.71452.63-200.36113.5254.7787.30450.80000.38914.4362.7087.84446.14200.42414.9070.9187.35454.28400.46315.6481.6086.9457.73JHM-500角度流量Q（m3/s）揚程H（m）功率P（kW）效率（%）比轉數(shù)ns-400.35910.7586.01534-200.39911.1986.85546000.42212.5087.27517200.44913.2887.60510400.47814.3087.80497600.50914.3587.39512JHM-600角度流量Q（m3/s）揚程H（m）功率P（kW）效率（%）比轉數(shù)ns-200.3609.1585.59604000.3949.4086.16619200.4299.7186.43628400.46410.4486.15620600.49510.5486.0163
