(1.Faculty of Mechancial & Electical Engineering, Hohai Univ., Changzhou 213022, China;2.Jiangsu Automation Research Institute, Lianyungang 222006,China) Abstract: It summarizes the research progres of the domestic solid-liquid two phase flow pump from the aspects of internal and external characteristic and hydraulic design, and briefly introduces the applications of the solid-liquid two phase flow pump in the rivers and lakes dredging engineering. Internal characteristic include the law of solid flow inside the pump and mathematics model of admixture in common use. External characteristic search after the law of the external parameter effect capability. At last, sum up the mans of design solid-liquid two phase flow pump domestic.
