在荷兰DELFT科技大学疏浚技术实验室进行了大量的离心泵高浓度泥砂输送实验。泥砂粒径分细砂、中砂和粗砂三种,泥砂浓度覆盖了生产应用中可能达到的范围,实验最高体积浓度达到42%,相应混合物密度达1700kg/m3。分析了高含砂量对泥泵扬程、效率、功率等性能参数的影响,为水力输送高浓度泥砂离心泵的设计和运行提供了依据。 In the Netherlands DELFT University Dredging Technology Laboratory carried out a large number of centrifugal pump high concentration sediment transport experiments. The size of silt is divided into fine sand, medium sand and coarse sand. The concentration of sediment covers the range that can be achieved in the production and application. The maximum volume concentration of experiment reaches 42% and the density of the corresponding mixture reaches 1700kg / m3. The influence of high sand content on performance parameters such as lift, efficiency and power of the mud pump is analyzed, which provides the basis for the design and operation of the high concentration silt centrifugal pump.
