摘要:
双向进出水流道泵装置可以同时满足引、排水功能，被广泛应用于沿江滨湖地区。但是由于双向进水流道形状功能的特殊性，进水喇叭管型线和悬空高度的匹配直接影响到流道出口水流的流态，严重影响泵装置的效率和运行稳定性。本文共设计了6 种喇叭管高度，并通过不同喇叭管高度对水力损失、出口流速均匀度以及出口水流平均偏流角的影响，选择了最优喇叭管高度。对优化后的泵装置模型进行全流场计算，验证优化后的进水流道与水泵匹配性。对优化后的泵装置模型进行外特性试验。试验结果表明，计算结果与试验值吻合较好，优化后的泵装置在不同工况下均可以稳定运行，最高装置效率可达76%，达到或接近单向立式泵装置的效率水平。
Abstract:
Pumping stations with bidirectional inlet and outlet channel were widely used in the area along Yangtze river and lakeshore，which could simultaneously satisfy the function of bidirectional diversion and drainage.However，due to the special shape and function of the two-way inlet channel，the matching between the inlet pipes and hanging height directly affected the flow pattern of the outlet channel，which seriously affected the efficiency and stability of the pump device.Six kinds of horn tube height were designed，and the optimal horn tube height was chosen through the influence on the hydraulic loss，exit velocity uniformity and outlet flow average bias angle by different horn tube height.The external characteristic test results of the optimized pump device model showed that the calculation results agree well with the experimental data，the optimized pump device could run stably in different working conditions，and the highest device efficiency was up to 76%，which could reach or near the efficiency of one-way vertical pump device.
