Abstract

The article presents the technological process of the residual pressure use and the centrifugal pumps consumption, when the transition process take place on pumping plant (changing the pressure and the flow of pumps in case of consumer’s location change), with the purpose to save the power by using jet devices in suction system. The analysis found, that the suction line of pumping plant does not influence on pressure changes when the consumer’ characteristics change as well. It influences on it when the additional energy grows.
