平原圩区有面广量大的流功机泵,动力为12马力柴油机或10～13千瓦小电机,泵为8～12英寸混流泵。由于安装简陋,无进出水池,弯头多,管道长,有的装有底阀,控制水泵运行转速不当,造成装置效率低,能源浪费非常严重,水费成本是一般固定站的2～3倍。针对这一问题,东台市水利局探索试验出将流动机泵改建为小型桩基泵站。这种改建采取钢筋混凝土预制构件,现场组装,浇筑混凝土固结,避免了打坝、排水、挖塘等施工程序,做到了水泵全落井倾斜安装,管短,弯少,结构紧凑,土建工程量少。实践表明改造后的泵站,提高了装置效
Plain polder area has a large number of large flow pump, power of 12 horsepower diesel engine or 10 ~ 13 kW small motor, pump for 8 to 12 inch Francis pump. Due to the simple installation, no access to the pool, elbow and pipe length, and some equipped with the end valve, control the pump speed is not operating properly, resulting in low efficiency of the device, energy waste is very serious, water costs are generally fixed station 2 to 3 times . In response to this problem, Dongtai Water Resources Bureau explored and experimented to rebuild the mobile pump into a small pile-based pumping station. This transformation to prefabricated reinforced concrete parts, on-site assembly, pouring concrete consolidation, to avoid the dam, drainage, digging ponds and other construction procedures, to achieve the pump tilting the whole shaft installation, short tube, less bending, compact structure, the amount of civil engineering less. Practice shows that after the transformation of the pumping station, improve the device efficiency
