Working Mechanism Of A Water Pumping Windmill 3D Animation

A windpump is a windmill used for pumping water, either as a source of fresh water from wells, or for draining low-lying areas of land.Windmill pumps transform kinetic energy from the wind straight into mechanical energy.

They comprise a vane pump or propeller mounted on a shaft and moved into the wind using a rudder, an upper structure with a transmission mechanism leading back to the well, a pump, most often submerged and an outlet for the water under pressure. Watch the video from Akshay Dafade for more info:

This motion drives a pump rod, up and down inside of a pipe in the well. A cylinder with a sealed plunger going up and down inside forces the water up the pipe. Each upstroke pulls water into the cylinder, while on the downstroke, a check valve in the bottom keeps the water from being pushed out, so the water is forced up the pipe with the next upstroke.


The structure’s height and the construction materials used are especially dependent on the maximum wind speed and any obstacles that may be located nearby.A common multi-bladed windpump usefully pumps with about 4%–8% of the annual windpower passing through the area it sweeps. This lower conversion is due to poor load matching between wind rotors and fixed-stroke piston pumps.wikipedia
