Research on the dynamics of single-acting crank pump with damless hydro turbine drive

Abstract

The research of the dynamic model of single-acting crank pump with damless hydro turbine drive has been made in the present work. Compiled dynamic and mathematical models of single-acting crank pump with damless hydro turbine drive have been constructed. The equations of motion have been solved using analytical and numerical methods and their results have been compared. The characteristics of the damless hydro turbine with the load of the crank pump have been evaluated depending on the radius of the rotor and on the speed of the watercourse. It has been revealed that the average angular velocity of rotation of hydro turbine in a stationary mode is the angular velocity of the hydro turbine at idle and does not depend on the mode of piston pumps. Average speed depends only on the parameters of a hydro turbine and the flow velocity of the watercourse.

The results obtained in the course of theoretical research can be successfully used for the design of hydro turbine as a drive for single-acting crank pump.
