含沙水流条件下泵站的节能运行研究

Research on energy saving operation of pumping station under condition of sediment flow

从地处山西省运城市的夹马口引黄泵站的工程实例出发,通过对含沙水流条件下水泵机组的能耗进行计算,得出了不同含沙水流条件下的水泵机组的单方水耗电量。计算结果表明:当含沙量为1~4 kg/m^3时,24SAP-10型水泵的单方水耗电量低;在含沙量为4~7 kg/m^3时,800S-76型水泵的单方水耗电量低;在含沙量为7~10 kg/m^3时,1200S-76型水泵的单方水耗电量低;当含沙量超过10 kg/m^3时,以上3种泵型水泵的单方水耗电量均急剧增加。根据计算结果,提出了泵站节能运行的措施,以有效降低泵站的运行成本。

Combined with the Jiamakou Pumping Station from Yellow River, at Yuncheng, Shanxi Province, we calculate the power consumption of various pumps that lift silt - laden flow with different concentrations, and obtain unit power consumption under silt - laden flow with different concentrations. The calculation results show that when the sediment concentration is 1 -4 kg/m^3 , 24SAP - 10 type pump has lower unit power consumption; when the sediment concentration is 4 -7 k g / m^3 , 800S - 76 type pump has lower unit power consumption; when the sediment concentration is 7 -10 k g / m^3 , 1200 S - 76 type pump has lower unit power consumption; when the sediment concentration is more than 10kg/m3 , the three kinds of pumps all have a sharp in-crease of unit power consumption. According to the calculation results, we put forward the measures of energy saving operation, so as to reduce the operating cost of the pumping station.
