Abstract:
Variable stroke technology （VST）, meaning for better matching between piston pump and wind rotor, is studied to apply in mechanical wind pumps. In the present study, the fundamentals of VST is analyzed, an equation of stroke-wind velocity is proposed, the performance of variable stroke wind pumps is also discussed. For predicting the output of this system, we adopted Raleigh distribution. Wind driven variable stroke reciprocating pumps are found to have obvious effect on the wind pump performance.[著者文摘]
