泵站进水流道内部流态模型试验方法研究

Study on Method for Model Test of Flow Pattern in Suction Box of Pumping Station

设计了泵站进水流道流态模型试验装置,不带模型泵进行了进水流道内部流态模型试验;介绍了“半肘形”进水流道和对拼钟形双向进水流道两种形式流道内内部流态的模型试验情况;结合应用实例,简述了不带模型泵、单独对进水流道进行模型试验研究的特点。

A special system of model test for flow pattern in a suction box of pumping station was designed, and a new method is put forward to carry out the model test for verifying a vertices band in suction box without relative model pump. Examples of model test applying the new method to verify vertices band in both “half elbow” suctionb oxa nd “bell-like” two-way suction box are illustrated respectively. Based on the two examples the advantages of the new method are summarized.
