yeah each joint will cause a dry point at the joints of the pipes and also a collection area for itI don't know about hard or dried bits - it's all water. Getting warmer the longer we test though.
It's a hydro turbine - only a piddly 90kW, but the generator has been reused from a simple asynchronous generator (3 phase motor), with a new shaft pressed into the rotor, end casing ring added to take the shaft seal and guide vane positioner:-
No @Parm , I just collated the data, drew up the spec, and found the right person to design and make it. Nevertheless my neck is well on the block if the project fails, but we'll only have spent a third of the cost of the original project. If it works it will pay for itself in 3 years or so.Did you make it?
I think you are mistaking it for a pump @gaz1 ....yeah each joint will cause a dry point at the joints of the pipes and also a collection area for it
it should have been round so nothing sticks to it
also it will be a git to clean out
also it would have been better keeping the speed of flow not expanding it to a larger pipe
the one you have is causing restrictions with flow therefore becomes hot

There we are then. I'm not going to argue with you - in fact you're right that the joins in the casing should be smooth, but that assumes you could blow mould it from plastic. It needs to reduce in size as the casing nears the end, at this size it would be difficult and expensive to cast. There are no bits to gather, it will be clean as a whistle inside, it will also be cold, since where I live the water temp barely gets above 10 degrees.no im not
wether its an air fan, water pump or slurry pump or even a sewage pump there basic design is flow of movement of the material
a smoother surface slows down the heat transfere due to movement of the material within it, if its restricted or has edges they cause heat within them and therefore the unit warms up rather well
edges also cause places for materials to collect and it will just get bigger and bigger until it finaly blocks same method with what happens within sewers and flow of pipes makes no difference
Yes, 90 kW, but we'll not trouble anything above 60Is the generator rated for 90kW? There's no mug against it for scale ;-) It looks quite a bit smaller than the oil drums nearby.
Just curious, what input head pressure are you working with? It takes a tremendous amount of pressure to get any useful work out of water, relatively speaking.Yes, 90 kW, but we'll not trouble anything above 60
i have other aplications where its usedA polite question if I may
Do you have knowledge / experience of this “thing” or it’s application ?
Remeber that this thing is a hydroelectric generator, not a pump, and it's running off clean water. The flow dynamics are quite different. It's not simply a case of reversing the flow.i have other aplications where its used
the plumbing sides is via drains and sewers
small pipes opening up to 10" or larger flow pipes when dealing with main sewer drains to old fashioned wall drains you walk through
the speed reference is via air systems that reduced pipe speeds the flow up to slow back down open up closer to the end saves on expensive materials
most are well based on water flow through pipes or better known as steam pipes as well

Do you have a picture of the guide vanes? Those linkages look pretty cool, why do they need to move though? I'd have thought it would be more "set and forget".I don't know about hard or dried bits - it's all water. Getting warmer the longer we test though.

Remember it's water, you can't speed up the flow without reducing the pipe size like you can with air.the speed reference is via air systems that reduced pipe speeds the flow up to slow back down open up closer to the end saves on expensive materials
