How To Engineer a Better OUTBOARD MOTOR WATERPUMP IMPELLOR 03 06 2019
A better outboard motor waterpump impellor could be designed so that the fans are spring loaded into a harder material gear. Instead of the current design whereby the rubber fans break off and clog the system as well as not pump adequately if they don't clog it because there is less vacuum force.
So the center of the impellor could be made out of graphite, nylon, Kevlar fiber reinforced... But it would have slots in it whereby the impellor blades fit into. A spring in each providing outward pressure.
The distance needed by the impellor fans could be minimal. Whereby they do not protrude very far.
One disadvantage could be, of this system, if not designed correctly... is that your motor could stall if a big particle where able to wedge itself in the impellor. So how could this be fail safed?
Very simply, and perhaps how it should be done already... the screen material should be finer. But in order to do that you would need to be able to remove it... much like how the trap door on a toaster is pulled out in order to dump the bread crumbs in the sink.
The question to ask yourself is, "Which system is more failsafe?"
If you were on a battlefield in war which would you want? Products are not engineered with that principle in mind today in the United States. "Plastic is still King Dinero" here.
There are numerous other ways to design an impellor system that might be applicable. Hinged fan blades at the base. Blades that have a centrifugal outward energy force to them, and perhaps a conical impellor.
Has to be a better way.
Perhaps the system needs a sensor in the intake before the impellor to detect any large particles. If detected they could be diverted outward of the system?
Another way is the standard drain trap type system. Whereby before water is pulled into the impellor it goes into a reservoir. It exits the reservoir on top of it. And the particles are trapped in the bottom of the reservoir. That would seem to be optimal to me.
The reservoir could have a simple flushing fitting. Or indeed turn a valve on the outboard it is automatically flushed.
Why don't we think this way? Because we live in a drunks world.
