HYDROGASDYNAMICS IN TECHNOLOGICAL PROCESSES: ANALYSIS OF THE OPERATIONAL CHARACTERISTICS OF A ROTOR-PULSATION APPARATUS WITH AN IMPELLER

摘要

Experimental and theoretical studies of the characteristics of a rotor-pulsation apparatus equipped with an impeller and a flow-regulating valve have been made. The dependences of the operating parameters of the apparatus on the rotor rotation frequency at four fixed positions of the valve have been determined. It has been shown that the experimental dependences of pressure in the discharge line and of net power on the number of rotations of the motor fully agree with the theoretical description from the viewpoint of the previously developed semiempirical model of the rotor-pulsation apparatus.
