Another 'thingy'!

I think you are correct Andy, given the diameter of the shaft there was a considerable force involved, isn't there a plan somewhere saying what all these things are ?

I'm sure there is but I'm not now, nor ever was, an engineer, Peter!
Cheers and stay safe !
More info:
Actually there are some rusted-up plaques with info but they need to be replaced as they are no longe legible. I managed to guess the TU of turbine and now that José Gafarot has advised me (below) that it is a Pelton high-pressure turbine, I can recall seeing the PEL of Pelton!

Estás exprimiendo bien las imágenes que encuentras a tu paso en Madrid.
En la plaza de Sol estaba la estatua del oso y madroño que son los símbolos de Madrid, a ver si me los recuerdas. También tienes el reloj de las campanadas de noche vieja

Of course I remember them! I used to teach daily not far from there. I posted a shot of that one and I think also one in Plaza de Felipe II, but on Panoramio, not ipernity.. And I no longer have access to these shots as well as the majority of my Cornwall shots (it's a long story!).

Superbe toujours de belles machines insolites .
Bonne soirée

Thank you, Malik!

looks like it goes whirly

Mny thanks, Blue and welcome!

There seems to be a few of these engines lying around Madrid - was there an exhibition or something at one time?

These pieces of old machinery (I have shown some others in recent pages) are all in the same park which is outside the Ministery of Transport and Public Works, or some such, Jenny

It is a Pelton turbine.
High pressure, low flow.

Thank you for that piece of information, José!

c'est insolite dans un parc

These pieces of old machinery (I have shown some others in recent pages) are all in the same park which is outside the Ministery of Transport and Public Works, or some such, Daniele.

Strange location ..
... well captured Andy.

These pieces of old machinery (I have shown some others in recent pages) are all in the same park which is outside the Ministery of Transport and Public Works, or some such, Jaap!

These mechanical oddments would certainly add a degree of novelty to the park, I can imagine that kids must enjoy poking around them.

Thank you, George!

Strange thing, Andy ! I don’r have not really an idea !

Thank you, Ulrich.
José Gafarot above, has given us the answer!

For me as mechanical engineer it was easy to identify this as an impeller of a water turbine, Jóse has given above an more precise designation - I'm to long out of that business :-)

Thank you,Volker!

I'm enjoying your images of these various "thingys" Andy. I think it's such a great idea to preserve them and put them on display as public artwork and great photographic subjects!

I agree, Keith! Hats off to the functionary who thought up the notion!

You have a good selection of thingies Andy and they make great pictures....I am still clueless ;-))

Please you like my thingies, Rosa!

HFF-Andy

Thanks, Fred but this isn't an HFF shot!

It had to have water involved but it's terriic capture And.

Pleased you like it, Roger. Thank you!

Hi Andy

A very nice picture, of this Pelton wheel.
As Jose says, used where there is a big head of water, as opposed to the traditional waterwheel which relies on a lot of water with only a few metres head..

Best Wishes, a nice weekend, and stay safe!!
Peter

It's a Pelton turbine for high pressure, as Peter stated!

Peter,
Berny,
I knew you would both know!

One wonders how this thing ended up here...

Because it is outside the Ministory of Transport and Public Works!
