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$\varphi$并通过实验对模型加以修正.修正系数$\varphi$经标准差分析,标准差为0.02,修正计算模型$H=\left\{\bar{\varphi}\left(S_{\mathrm{EQ}}+S_{\mathrm{COD}}\right)+\frac{8}{g \pi^{2} d^{4}}\right\} Q_{z}^{2}$能够满足工程设计需求.

Abstract: 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 $H=\left\{\bar{\varphi}\left(S_{\mathrm{EQ}}+S_{\mathrm{COD}}\right)+\frac{8}{g \pi^{2} d^{4}}\right\} Q_{z}^{2}$ meets the engineering design requirements.

Key words: siphon water decanter, rocker arm intake head, hydraulic calculation, mathematical model
