RECIPROCATING WINDMILL PUMPING SYSTEM

摘要

A system for pumping water from a well (32) drilled into an underground water source (44) that is operable in association with the windmill (10) having a tower frame (14), a wind driven turbine (12), and a reciprocating pump shaft (16) operably connected to the turbine. The system includes an air pump (20) mechanically linked to the reciprocating pump shaft (16) of the windmill (10) and operable by the direct reciprocating motion of the shaft (16). The air pump (20) operates through the reciprocating motion of the windmill shaft (16) and delivers a flow of compressed air into the well (32) down to a point below the water level within the well (32). An air lift fluid pump (20, 36) is positioned within the well (32) and comprises a submerged mixing chamber wherein compressed air is injected into the mixing chamber forming a buoyant air-water mixture. This buoyant mixture flows towards the surface which in turn draws water up through the fluid conduit (38) to the surface.
