英文摘要	The solid-liquid two-phase unsteady flow in the screw centrifugal pump is simulated during one revolution by using CFD software. The pressure fluctuations at the volute outlet, the distribution of radial thrust and axial thrust in the screw centrifugal pump during one revolution are given in the paper. The results show that the minimum pressure value at the volute outlet occurs when the maximum impeller radius just turned the tongue of volute, and maximum value occurs when the maximum impeller radius just turned between the section. and.; the radial thrust on the impeller is assumed the circumference distribution approximately during one revolution. As the solid volume fraction increases, the radial thrust increases gradually. The direction of radial thrust is inverse against the maximum value of pressure in the pump outlet; the maximum radius position has much influence on the changes of axial thrust, the axial thrust maximum value occurs when the maximum impeller radius just turned the tongue of volute, and minimum value occurs when the maximum impeller radius is away from the tongue of volute.
