一、任务的由来上海郊区的电力灌溉泵站始建于1956年,经过三十多年的长期运行,泵站建筑物塌裂破损,机泵设备陈旧老化严重,造成泵站装置效率偏低,能耗增加,效益衰减,影响安全运行。1989年对全市5878座灌溉泵站进行普查摸底,其中泵站建筑物、电动机、水泵,按水利部《泵站技术规范》规定,应报废更新而至今仍在超期服役的分别占38.6％、41.4％、41.7 ％。这对上海郊区的农业生产是一个严重的潜在威胁。
First, the origin of the task Shanghai suburban electric irrigation pump station was built in 1956, after more than thirty years of long-term operation, collapse of the pump station building damage, aging pump equipment is serious, resulting in low efficiency pumping station device, Increased energy consumption, efficiency decay, affecting safe operation. In 1989, 5878 irrigation pump stations in the city were surveyed. Among them, pumping station buildings, electric motors and pumps, according to the Technical Specifications for Pumping Station of the Ministry of Water Resources, should be scrapped and updated, and still account for 38.6% and 41.4 respectively of overdue services. %, 41.7%. This is a serious potential threat to agricultural production in the suburbs of Shanghai.
