一、概述国内所建成的低扬程抽水站中大多数选用立式轴流泵。泵站的装置是由出泵、进水流道和出水流道构成一个不可分割的整体。以往在进行设计时,机械部门着重设计、研究水泵叶型和结构;水利工程部门往往撒开水泵而孤立地对进水流道、出水流道进行设计。从水泵装置的整体分析看,将水泵和进、出水流道分别单独进行设计研究是很不全面的。过去由于试验条件的限制,只能分别进行试验 First, an overview of the domestic low-lift pumping station built most of the selection of vertical axial flow pump. Pumping station device is a pump, water inlet and outlet channels form an integral whole. In the past when designing, the mechanical department focused on the design and study of the pump type and structure; and the hydraulic engineering department often drew the water pump and designed the inlet channel and the outlet channel in isolation. From the overall analysis of the pump device, the pump and the inlet and outlet channels, respectively, a separate design study is very comprehensive. In the past due to the limitations of the test conditions, only the test separately
