title: INCREASING THE LEVEL OF ENVIRONMENTAL SAFETY OF PUMPING UNITS BY ENERGY SAVING DURING REGULATION
abstract: The relevance of improving calculation methods for pumping units of hydraulic systems in order to save energy and correspondingly increase their level of environmental safety is substantiated. To speed up hydraulic calculations and increase their accuracy, it is proposed to approximate the existing characteristics of centrifugal pumps, which are usually presented in the equipment passport in graphic form, with a quadratic parabola. The general equations for the analytical determination of the wo
