Continuously variable transmissions with torque-sensing regulators in waterpumping windmills

摘要: Abstract One widespread application of wind energy is in waterpumping. Usually windmills are coupled to water pumps, though piston pumps difficult match turbines. In the first approximation, pump requires a constant torque turbine at all rotational speeds. Conversely, if were operate maximum efficiency levels, it would supply proportional square speed. Hence, combination windmill and be maximally efficient only for single This paper suggests incorporating continuously variable transmission (C.V.T.) between enhance windpumpers different The feasibility adopting automatically regulated C.V.T.s, which adjust their ratio without requiring sophisticated regulators or control systems, also examined since such solution does not undermine cost-effectiveness, reliability simplicity system. A mathematical model has been relied on simulate operation windpumper equipped with C.V.T. sensing regulator. advantages terms rate flow demonstrated assuming that waterpumping system installed two locations Somalia. Finally, examines dynamic behaviour proposed.
