Status of Research of Hydraulic Turbines for Energy Recovery

The application of hydraulic energy recovery turbines plays an important role in energy saving and emission reduction. There are four structure forms of hydraulic energy recovery turbines: pumps as turbines,impulse turbines,vane-guided turbines and specialized hydraulic energy recovery turbines. The configuration of energy recovery unit is of two modes: hydraulic energy recovery turbine drives pump or blower directly and it serves as assist device for motor. The research status of hydraulic energy recovery turbines both at home and abroad are summarized and it found that studies separated several aspects: turbine selection calculation,optimization design for turbine runner,rotating speed stability control of turbine,force condition and structure strength of turbine and turbine velocity slip. Hydraulic energy recovery turbine has an abroad application in various hydraulic systems and studies are developing to specialization and diversification directions.
