Design method of dredge pump impeller structure suitable for different soil textures

The invention provides a design method of a dredge pump impeller structure suitable for different soil properties, and belongs to the technical field of dredge pump design. According to the technical scheme, particle size parameters and blade wrap angles of dredged soil are increased according to a calculation formula of the blade number of the clean water pump impeller, a calculation formula of the blade number of the dredge pump impeller is designed, and the blade number Z of the dredge pump impeller is determined according to the formula. Compared with the prior art, the dredge pump has the beneficial effects that one dredge pump can replace the impeller suitable for the soil texture according to the change of the dredged soil texture under different dredging working conditions, and the dredge pump always operates efficiently under the condition that it is guaranteed that the dredge pump is not blocked. 本发明提供适用于不同土质的泥泵叶轮结构的设计方法，属于泥泵设计技术领域。本发明采用的技术方案是：根据清水泵叶轮的叶片数的计算公式，增加了疏浚土质的粒径参数和叶片包角，设计出了泥泵叶轮的叶片数计算公式，并根据该
