摘　　要：针对高扬程泵站水锤防护中空气罐参数优化问题,以无量纲最大水锤压力值为控制目标,以泵无量纲倒转转速和管线最小水锤压力值为约束条件,以空气罐直径、高度、罐内初始水深、连接管直径和空气罐安装位置为变量,建立空气罐水锤防护参数优化模型,并针对某供水工程,利用混合粒子群算法开展空气罐水锤防护特性与尺寸优化研究。结果表明:随着空气罐体积的增加,最大水锤压力逐渐下降,泵最大倒转转速逐渐增大,最小水锤压力在-7 m波动,空气罐的径高比总体呈现上升趋势,而水深比则呈现下降趋势,连接管径比基本不变;空气罐设计规律为径高比、水深比和连接管径比分别取1.00、0.58和0.43;空气罐设计值与最优值的水锤防护效果接近,泵出口最大水锤压力偏差的最大值近1.73%,证明该设计规律具有可行性,为空气罐的尺寸设计与水锤防护应用提供了参考依据。Aiming at the air vessel parameter optimization problem in water hammer protection in high-lift pumping station,taking the maximum dimensionless water hammer pressure as the control target,the dimensionless reverse speed of pump and the minimum water hammer pressure value of pipeline as the constraints,and the air vessel diameter,height,initial water depth,connecting pipe diameter and air tank installation position as variables,the parameter optimization model of water hammer protection of air vessel is established.For a water supply project,hybrid particle swarm optimization algorithm is used to study the water hammer protection characteristics and size optimization of air vessel.The results show that with the increase of the air vessel volume,the maximum water hammer pressure decreases,the maximum reverse speed of the pump increases gradually.The minimum water hammer pressure fluctuates within-7 m,the diameter to height ratio generally shows an upward trend,the water depth ratio shows a downward trend,and the connection pipe diameter ratio is basically unchanged.On this basis,the design law of air vessel is obtained,that is,the ratios of diameter to height,water depth ratio and connecting pipe diameter ratio can be taken as 1.00,0.58 and 0.43.Then,the water hammer protection effect of the air vessel of the design value is compared with that of the optimal value,it is concluded that the water hammer protection effects of the design value and the optimal value of the air vessel are close,the maximum deviation of the maximum water hammer pressure at the pump outlet is nearly 1.73%,proving the feasibility of the design law,which provides a reference basis for the size design of air vessel and the application of water hammer protection.
