2011年2月26日 · We have a small (1m diameter) overshot metal water wheel installed in our stream, which takes the entire flow of the stream via a chute, but are having problems trying to find the right generator for it. We've tried two off-the-shelf wind turbine permanent magnet generators/alternators so far.

2013年5月16日 · As someone who's built over 400 water wheels and hooked gearing to a few of them for making electricity let me give you a few ideas. First a formula. height in feet X flow in gpm X .000253 X efficiency (.55 for wheel and generater set or .80 for a well designed water wheel axle hp) = hp. so @ 1063 gpm with a 6.9 foot diamater wheel would look like this. 6.9 X 1063 X .000253 X .55 = 1.02 hp ...

2013年4月6日 · The water wheel must be light weight so it can be removed when the river freezes over. My idea is to use whole barrels, attach paddles arround each barrel and an axle through the center.

2006年5月7日 · I installed the Pelton wheel PM generator by the creek about a month ago. Water is plentiful (approx. 30 - 50 liters/sec. Now I get less than 100 watts and according to Nando should give close to 300 watts.

2011年2月9日 · The wheel itself was damaged by debris floating down in high water in spring 2010, so by the meters (in video) it was making about 1.2 kW when i visited. When all the paddles are in place, it would be making about 3kW and spinning at a higher RPM.

2009年1月19日 · I build water wheels and am trying to put together a simple power producing system for people who have enough flow and head to produce power yet who prefer the beauty of a water wheel over a low head turbine.

2007年9月20日 · Water gains about 19 PSI for every 10 feet of head when it is contained in a pipe. From 50 feet to 100 feet, you might be interested in a high RPM "Pelton Wheel". It uses a small volume of water, but a high-pressure jet shoots at "spoons" around its rim that allow the water jet to flow around a curved path to extract as much energy as possible.

2016年8月10日 · I'm certainly not an expert, but it seems to me that either the ram pump or the water wheel (Pelton or other), are two approaches to use the power of water to pump water and would not likely be used at the same time for the same application.

2018年2月6日 · Probably the easiest thing to do at this time is prevent water from the wheel dripping onto the V belts by building a shroud of some sort. What really interests me is making a custom direct-drive generator using the existing large 5' diameter pulley as the rotor.

2014年7月23日 · The generator I am spec'ing is a 5kw 50 rpm PM style. I have machine shop and welding resources. The design: The wheel will be 10 feet in diameter and three feet wide. The 24 buckets are rolled aluminum and the wheel sides are aluminum as well.
