Understanding the Undershot Water Wheel Design
There are many types of water wheels that can be used in a hydropower project.
There are water wheels designs that can meet the demands of anyone.
There are designs for the DIY-type of person wanting to create his mini hydropower plant. And there are designs that can appeal to the fun-seeking persons just wanting to experience having one in their property.
One such type of the water wheel is the undershot wheel, and you can also expect the availability of undershot water wheel design as well. But before going into the undershot waterwheel design, here’s a little backgrounder on the undershot water wheel and the DIY water wheel generator.
What is referred to as the undershot type is also known in other circles as the stream wheel. This is vertically-mounted wheel that is rotated by water striking blades at the bottom. This is where it got its name- the striking that happens at the bottom. And of all the many types of water wheel, this is considered as the oldest type. Though in terms of efficiencies, the undershot water wheel design is questionable still there are a number of enthusiasts that go the way of this design. The good thing about this type is that this is cheaper and simple to build. And also this can be installed as well on floating platform.
Another thing going against this type of water wheel is that this does not gain any type of benefits from the head, and for this reason this is the type of water wheel that is recommended for shallow rivers.
The undershot wheel design has been in use for many centuries now. And the oldest version of the undershot type typically looks like a paddle wheel that is positioned in the paddle steamer. The lowest parts of the paddle wheel are dipped into the moving water, and the movement of the water is the force that actually moves the wheel to move backwards.
It has been said that is one of the many forces that pushed the Industrial Revolution into something that everyone now appreciates. In fact, some are saying that the undershot type of water wheel was the same thing that also sets off the interest for the steam power.
If you are looking forward to testing the water wheel designs for use in the property, then consider some of the suggestions that forwarded on the proper construction of the wheel.
The common instruction is that the moving water should be fed into the wheel in less than half-way up. The flume should continue to trace the curve of the water wheel down to a position just under the axle. And the curved channel should be properly fitted to the wheel in such a way that water is trapped and that there is no slippage that will happen.
The flume from this design can be constructed from cement or wood. Just make sure that on the water wheel calculations, a filtering mechanism should be present to avoid debris. And also on that same undershot water wheel power calculation, an overflow reservoir should be present to accommodate the debris that was bypassed.
If you are thinking of adopting the undershot waterwheel generator, consider and take careful look always at the undershot water wheel power calculation in order to maximize power generation.
