It is by the liquid and solid two phase flow theory that this article brings forward not only a calculating method of the maximum discharge which can prevent cavitation in dredging slush pumps and their pipeline systems, but also a calculating method of the minimum discharge which can minimize the loss of the pump pipeline systems and ensure the stability of the operation of the systems. The authors of this article also tell how to determine the operation parameters of the slush pump systems...

It is by the liquid and solid two phase flow theory that this article brings forward not only a calculating method of the maximum discharge which can prevent cavitation in dredging slush pumps and their pipeline systems, but also a calculating method of the minimum discharge which can minimize the loss of the pump pipeline systems and ensure the stability of the operation of the systems. The authors of this article also tell how to determine the operation parameters of the slush pump systems under the condition of the rated horsepower of the main motors. Calculations of a few cases show that the theoretical values derived by using the formulae given in this article are approximate to the experimental data. From the calculation data, diagrams are made, which are convenient to use and would be helpful to the search of reliability and effectiveness of slush pump systems.
