Windmills Harvest the Breeze
Although the water-pumping American windmill has survived into the 21st century pretty much unchanged for 100 years, there is renewed interest in using windmills to do all kinds of work, including some new water pumping designs.
The original style water-pumping mills work when the wind turns the wheel, which in turn spins a crankshaft. The pump, which is submerged in the well, moves water when a piston is pulled up inside its cylinder. The pump’s piston is attached to the windmill’s crankshaft using a long piece of wood, steel or, in some cases, fiberglass. This so-called sucker rod is responsible for connecting the pump to the power source.www.Airliftech.com/index.html.
