无锡市下管无锡、宜兴、江阴三县及郊区,现有8时以上口径固定灌排站6700余座,其中混流泵站5000余座,占74％。由于多种原因,这批混流泵站技术性能差、能耗高、灌排标准低、经济效益较差,我市于1983、1984两年组织专业班子,对3001座泵站、3544台套机组进行了测试,平均装置效 Wuxi City, under the control of Wuxi, Yixing, Jiangyin three counties and the suburbs, the existing more than 8 o’clock fixed irrigation and drainage stations more than 6,700, of which more than 5,000 mixed-flow pumping station, accounting for 74%. Due to a variety of reasons, these mixed-flow pumping stations have poor technical performance, high energy consumption, low standard of irrigation and drainage, and poor economic benefits. The city organized professional teams in 1983 and 1984 for 3001 pumping stations and 3544 sets of sets of units Tested, average device effectiveness
