一九八四年一月,水箱引水式无底阀抽水装置在我县回龙乡青杠堰电灌站12SH—13A水泵、75千瓦电动机组上进行了现场抽水技术鉴定:水泵出水量增加13％,单位水方能耗下降5.9％、装机效率提高3％。为了适应我县电灌站现有机组设备条件差的状况,使水箱装置能更好地应用于实际生产,发挥经济效益。在今年推广使用工作中,针对水泵种类结构形式不同的特点,我们在单吸泵(8BA—12)上安装了水箱装
In January 1984, the water tank-type bottomless valve pumping unit conducted on-site pumping technology appraisal on 12SH-13A pump and 75-kilowatt electric motor unit at Qingbar weir Irrigation Station of Huilong Township in our county: the pump water output increased by 13% , Unit water consumption decreased by 5.9%, installed capacity increased by 3%. In order to meet the poor condition of the existing unit equipment in the county electric pumping station, the water tank device can be better applied to actual production and bring economic benefits into play. In this year’s promotion work, in view of the different types of pump structure, we installed a single suction pump (8BA-12) installed on the tank
