关醒凡-轴流泵和斜流泵模型及工程应用1

1、第八章 轴流泵和斜流泵模型及工程应用 大学泵水力模型试验研究课题组，从 2000年起至今已坚持试验 8 年多。 研究容：系列轴流泵模型、贯流泵模型、双向泵模型、系列可调节叶片斜流 泵模型。系列轴流泵模型（含双向泵模型） ，参加水利部南水北调工程水泵模型天津 同台测试。贯流泵模型 JGM-3 经河海大学试验台复试，装置效率 79.05%。斜流 泵模型JHM-450,在天津试验台进行装置试验（引嫩入白工程五家子泵站），装 置最优效率达 84.3%。比转速为 800的斜流泵模型，可替代一大部分轴流泵，实 现适应扬程变化围大和高效围广的突出优点。应用厂家：日立泵制造、KSB泵、中力设备（高邮水泵厂）、

2、水泵厂、凯泉泵 业集团、天鹅工业泵股份、 三益江海泵业等。典型用例：轴流泵模型：南水北调工程江都四站、万年闸站、台儿庄站、山站； 通榆河 送水工程 大套站；中部四省泵站改造工程明山泵站等。贯流泵模型：通榆河送水工程灌南泵站、后善泵站。双向泵模型：黄麻涌、北窖、五沙三村等泵站。 斜流泵模型：行泵站、广平泵站、引嫩入白工程五家子泵站、许多电厂（包 括出口到苏丹、印度、巴西等国）的循环水泵。第一节 系列轴流泵模型天津同台测试数据和曲线、系列轴流泵模型参数表（表 8-1 ）、系列轴流泵模型综合特性曲线和试验数据1、图8-1 TJ04-ZL-08综合特性曲线；表8-2 TJ04-ZL-08试验数据2、图
