摘　　要：通过水力等效建立了摇臂取水头部的简化模型,通过能量守恒方程建立了摇臂式虹吸滗水器的理论计算模型,在理论计算模型中引入修正系数φ并通过实验对模型加以修正.修正系数φ经标准差分析,标准差为0.02,修正计算模型H={φ^(-)(S_(EQ)+S_(COD))+8/gπ^(2)d^(4)}Q_(z)^(2)能够满足工程设计需求.A simplified model of rocker arm intake head is established based on hydraulic equivalence,and a theoretical calculation model is established using the energy conservation equation.A correction factor is introduced in the theoretical model,which is further refined through experimental validation.Statistical analysis of the correction coefficient yields a standard deviation of 0.02,indicating that the modified calculation model H={φ^(-)(S_(EQ)+S_(COD))+8/gπ^(2)d^(4)}Q_(z)^(2)meets the engineering design requirements.
