摘要:
为探究轮缘处载荷分布对混流泵性能的影响从而进一步提升其性能。本研究以中比转速导叶式混流泵为研究对象,采用反问题设计通过修改叶轮叶片轮缘处载荷分布,设计了前载、中载和后载三种载荷分布形式,对比分析了不同轮缘处载荷分布对混流泵性能的影响。研究结果表明:后载有利于小流量至设计流量工况下泵段效率的提升,最大提升幅度为2.92%,出现于0.5倍设计流量;前载有利于设计流量至大流量工况下泵段效率的提升,最大提升幅度为20.05%,出现于1.3倍设计流量。所有工况下,前载均具有最高的扬程,而后载扬程则最低,最大差值出现于1.3倍设计流量,为2.33 m。内流分析表明流动分离所造成的湍动能变化,是导致模型性能差异产生的主要原因。
Abstract:
To investigate the influence of load distribution at the rim on the performance of mixed flow pumps and further improve their performance. This study takes a medium specific speed guide vane mixed flow pump as the research object, and adopts inverse design method to modify the load distribution at the rim of the impeller blades. Three types of load distribution forms, namely front loaded, mid loaded, and rear loaded, were designed, and the influence of different load distributions at the rim on the performance of the mixed flow pump was compared and analyzed. The research results show that: the rear loaded distribution is beneficial to improving the pump efficiency under the operating conditions from small flow rate to design flow rate, with the maximum increase amplitude of 2.92%, which occurs at 0.5 times the design flow rate; the front loaded distribution is beneficial to improving the pump efficiency under the operating conditions from design flow rate to large flow rate, with the maximum increase amplitude of 20.05%, which occurs at 1.3 times the design flow rate. Under all operating conditions, the front loaded distribution has the highest head, while the rear loaded distribution has the lowest head. The maximum difference occurs at 1.3 times the design flow rate, which is 2.33 meters. Internal flow analysis shows that the change in turbulent kinetic energy caused by flow separation is the main reason for the performance differences among the models.
