Experimental Study of Hydraulic Energy Recovery System

The paper explores topics related to the operation and application of hydraulic energy recovery systems. Features of operation and application of different types of power drive machines are considered. The paper presents the results obtained from the testing in laboratory conditions of energy recovery systems operating in open and closed loop. The operation of a stabilizing unit in the system was evaluated and the efficiency coefficient was determined. It is investigated the work of feed pump operating in turbine mode, known as Pumps as Turbines (PAT) in open and closed loop operation. The coefficient of performance was evaluated for the operation of the energy recovery system (ERS) with a stabilizer unit and the ERS composed only of a PAT driven centrifugal pump.
