水泵叶轮内液流的流动状况是一种三维空间运动形式。其流动状态极其复杂,且又高速转动。人们对高效、节能、大流量、高压、高速、使用寿命长的水泵需求愈来愈迫切,我们为了获得新的更有价值的设计理论,利用高速摄影能记录和跟踪高速运动物体的状态和过程这一特点,开展了对离心泵叶轮流道内液流速度的拍摄与分析,其大体步骤如下:
The flow of fluid within the pump impeller is a three-dimensional space motion. Its flow is extremely complex and is rotating at high speed. Demand for pumps that are efficient, energy-efficient, high-flow, high-pressure, high-speed, and long-lasting is becoming more and more urgent and we use high-speed photography to record and track the state and process of high- speed moving objects in order to gain new and valuable design theories This feature, carried out on the centrifugal pump impeller flow velocity of the filming and analysis, the general steps are as follows:
