That's what I saw!
2 half wheels would have been better for a better performance since the return of the water on the spoon also acts on the performance!
Can you give me the model and the manufacturer of the Pelton SVP?

the classic pelton solution is with a jet in the plane of the wheel, with spoon slotted in the middle of rather complicated shape: advantage not of axial force on the tree
but your solution is very smart too: spoon a little inclined, spoon more simple than the classic pelton
the belt is a practical solution for testing, I think that when the main problems are solved you can optimize
the small diameter of the pipe worries me a little, what is there at the end to make the jet?
the hole that makes the jet must be much smaller than the pipe, so the speed in the pipe is low, no loss of energy, and it is just before the turbine that the pressure is converted into speed by a conical nozzle : in addition we can put a conical needle inside to regulate as we want the power of the jet without changing the speed, which depends only on the pressure

The nozzle at the end of the pipe is the right diameter but I had to use basic plumbing reducers to go from the diameter of the pipe to that of the nozzle so I think I also have a lot of losses by this reduction "in steps" and not conical, I did not find someone capable of making me the adequate part ...

In my opinion it must not be good, the cone must be much longer, and without abrupt reduction of the diameter as currently at the screw connection.
Being a kid I was passionate about the water mill, I made a lot (small) and I had the opportunity to experiment all kinds of forced pipes, the shape and length of the cone plays a lot.

a beautiful conical shape is important where it is the smallest ... to the biggest if it is sudden change it is less serious, it is part of the details that you can improve later
what scares me is the connection in pvc glued ... it looks like ordinary PVC sewer, not even pvc pressure ... ca risk to peter before 18bar
in any case I like your slanted peleton: it is an idea that I wanted to try which seemed to me better than the classic peleton ... missed it my copied my idea by telepathy

Hello,
Here is the link to the manufacturer of the Pelton wheel (on Ebay Italy)
http://cgi.ebay.it/TURBINA-PELTON-HYDRO ... 1212wt_924
and the one towards the generator
http://cgi.ebay.fr/eolienne-windturbine ... 1528wt_754
The manufacturer of the Pelton wheel also sells nozzles of different sizes and adapted to the operation of the wheel, I asked him a question asking him for more details ...
See you

Your turbine comes from the USA and is sold by the Italians!
How did you calculate the necessary rotational speed in relation to the generator?
The smooth belt slides surely at the point of load when reaching the necessary voltage.
Revising the training would be in my opinion the first thing to do in your case!
