Frankinpump he go buggerup.

Frankinpump started making some rather loud noises the last time I used it.

Removing the pump from my tangle of pipe work, reveled a broken cooling fan.

Oh dear, how do I fix this on a Sunday?  Answers on a post card please.










I've increased the size of most part for added strength given the blades large radiuses at their intersections and extended them to the central boss.  I'm not sure if this will affect the efficiency, but it will make them much stronger.


I'll add a write up on the 3D parts page of the wiki.

And peeps ask why would we need a 3d printer.

I'd have gone for intermediate blades similar to the original ones as well.

All decent pumps have 12 fan blades.

[Julian]

I did look on Google images to check about extending the blades to the boss and the number of blades seem to vary between 5 and 16.

I have a suspicion that the gap between the blades and the boss may act like a suction port, but we'll see when I get the thing put back together.  As long as it shifts a reasonable volume of air I'll be happy.

I bet you broke it on purpose just so you could use that damn 3D printer thingy

[Jamesrl]

Envy and Jealousy, just 'cause you ain't got one.

I think you may well be right.

KH is right, any normal person would have just slapped some glue on it, put a jubilee clip around the boss and forgotten about it.

Yes, well said ... I didn't think of that!

And the pump would vibrate like feck 'cause it'd be so far out of balance.

Don't agree with the Luddites Julian you did the right thing, left to peeps like those we'd still be living in caves.

[Tony]

Good use of the 3D printer that is.  Now you've got me thinking about replacing the broken plastic fan housing on my dispensing vane pump.

[K.H]

Dont you start as well!

[Jamesrl]

Give up now, you're out numbered.

if you were really clever you could profile the blades to a NACA profile based on the speed of the motor. that way it would be running at maximum efficiency resulting in greater airflow thus increasing the available power to the pump by using autodesk virtual wind tunnel.

Dam, I didn't think of that either.

Mind you the original fan was pretty NACAd in the first place.
