建国以来,为了适应工农业生产的需要,太原市机电排灌事业发展很快。由于长时期运行和其它原因,不少电灌站工程陈旧,设备老化,导致泵站效率低,能源消耗大,提水成本大大增加,因此,以提高泵站经济效益为目的的泵站技术改造,是当前重要的任务。太原市水利局于1984年选择了有改造条件的敦化电灌站一级站进行节能技术改造。根据敦化电灌站多年运行中存在的问题,因地制宜地采取一些综合性技术措施,使泵站效率由38%提高到56.7%;能源单耗由7千瓦小时/千吨米降低到5千瓦小时/千吨米,达到了部颁的考核标准。一、泵站技术改造前后的基本情况敦化电灌站位于太原市清徐县内,是一
Since the founding of the PRC, in order to meet the needs of industrial and agricultural production, Taiyuan electromechanical irrigation and drainage has developed rapidly. Due to the long-term operation and other reasons, many electric pumping station projects are obsolete and the equipment is aging. As a result, pump stations are inefficient, energy is consumed and the cost of pumping water is greatly increased. Therefore, in order to improve the economic benefits of pump stations, Is the current important task. Taiyuan Water Conservancy Bureau in 1984 has selected the conditions for the transformation of Dunhua Electric Station a station for energy-saving technological transformation. According to the problems existing in the operation of Dunhua Electric Irrigation Station for many years, some comprehensive technical measures were taken according to local conditions to increase pumping station efficiency from 38% to 56.7%; and energy consumption was reduced from 7kWh / kT to 5kWh / k Ton of rice, reached the ministerial examination standards. First, the basic situation before and after pumping station technological transformation Dunhua electric pumping station is located in Qingxu County, Taiyuan, is a
