过去,机组装置效率仅有40％的津期店扬水站,经淘汰老型号水泵和动力机,重新选配节能水泵和配套电动机,使机组效率一下子提高了18％,还增加了提水能力,扩大了灌溉面积。这是山东省夏津县泵站技术改造的一例。目前,泵站技改这项花钱少、见效快、受益大的工程正在夏津县全面展开。位于鲁西北边缘的夏津县地势高亢,十年九旱。为解决当地水源紧缺问题,该县先后在卫运河、马颊河和县内支流河道上兴建了113处引卫、引黄泵站,这批总装机260台14265千瓦、总提水能力119立方米每秒的泵站,每年灌溉农田54万亩,占全县总灌溉面积的75％,为全县经济的发展做出了贡献。但是,随着运行时间的增加,泵站设备超期服役、型号陈旧、配套不合理、能耗大、效
In the past, the unit installation efficiency of only 40% of the Jinyang shop Yang pumping station, the old models of pumps and power machines out of phase, re-matching energy-saving pumps and motor, the unit efficiency suddenly increased by 18%, but also increased the ability to lift, Expand irrigation area. This is an example of technical transformation of Xiajin County Pump Station in Shandong Province. At present, pumping station technical transformation of this less expensive, quick, big benefit projects are in full swing in Xiajin County. Xiajin County, located in the northwest of Shandong Province, is characterized by high altitude and ten years of drought. In order to solve the problem of shortage of local water resources, the county has successively constructed 113 Guiding and Diversion Yellow River pumping stations on Wei River, Majia River and the tributary rivers in the county. These total installed capacity of 260 sets is 14,265 kilowatts with a total lifting capacity of 119 cubic meters Pumping stations per second, 540000 acres of irrigated farmland each year, accounting for 75% of the total irrigated area of the county, for the county economic development has made its contribution. However, with the increase of operating time, pumping station equipment overdue service, model obsolete, supporting unreasonable, energy consumption, efficiency
