| 摘 要： | 本文通过观察同一水位下各种不同的流量及保持流量不变改变淹没深度时的流态、旋涡及吸气状况,研究了泵站进水口的旋涡特性及旋涡发生、发展的影响因素,得出了旋涡类型随淹没深度的变化规律,就后壁距等边界条件对临界淹没深度的影响进行了试验研究,並导出了临界淹没深度的经验公式。

| Abstract: | In this paper, the characteristics of vortices in intake of the pump and the influence factors of vortex are studied and the relationship between the types of vortex and submergence depth is found out by observing flowconditions, vortices and air invasion at a definite water level & different discharges or with a constant discharge & various submergence depths.The effect of boundary conditions on critical submergence depth, such as the effect of the disftance from the back wall of the intake chamber etc.,is also investigated, and an empirical formula of critical submergence depth is thereby established. |
