关醒凡-轴流泵和斜流泵模型及工程应用1.doc

第八章 轴流泵和斜流泵模型及工程应用江苏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。研究内容：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，实现适应扬程变化范围大和高效范围广的突出优点。应用厂家：日立泵制造无锡有限公司、上海KSB泵有限公司、江苏中天水力设备有限公司（高邮水泵厂）、长沙水泵厂有限公司、上海凯泉泵业集团有限公司、长沙天鹅工业泵股份有限公司、 合肥三益江海泵业有限公司等。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、刘山站；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河北泵站、后善河南泵站。双向泵模型：广东黄麻涌、北窖、五沙三村等泵站。斜流泵模型：上海陈行泵站、广西安平泵站、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
