MODELING OF Q-H CHARACTERISTICS OF THE ELECTRIC DRIVE WITH A VORTEX ELECTRICAL PUMP
Известия высших учебных заведений: Нефть и газ, 2015 In this paper we consider the possibility of modeling the performance characteristics of the electric drive with a vortex electric pump. The structure of the vortex electric pump studied for the experiment is considered, as well as its Q-H characteristic.
