摘要
从刘老涧泵站运行中存在的主要问题出发,泵站改造采用水泵叶轮直径不变,转速减小,改善水泵的空化性能,对关键支撑部位、水泵轴与叶轮座连接形式和水泵叶片固定方式等进行了改造,有效减小了水泵叶轮的运行摆度和不稳定性,并选用流量系数较大的水力模型以满足流量的要求,提出泵站水力机械设计的合理改造措施。
Starting from the main problems existing in the operation of Liu Laojian Pumping Station,the improvement of pump cavitation performance by using the constant diameter of pump impeller,the reduction of speed,the transformation of key supporting parts,the connection form between pump shaft and impeller seat and the fixed way of pump blade,etc.,which effectively reduced the swing and instability of pump impeller,and selected hydraulic model with larger flow coefficient to meet the flow rate requirement and put forward reasonable reformation measures for hydraulic machinery design of pumping station.
