Off-grid hydro installation with rocks in pipe
HTML-код
- Опубликовано: 26 авг 2024
- Very midgy installation, also with many small rocks being drawn into pipeline by the vacuum from closing the intake sluice. Some good pipe flushing action. Turbine is sited outside old shed to be on top of tailrace.
Ultimately frustrated due to record drought conditions. Only enough water in storage pond for a few hours of operation. Waiting for rain now. New Sunny island inverter and batteries and legacy Lister diesel. Some breeding Falcons and a collie dog.
@corsomail1 The pipe was installed by the owner of the system to save money. There were some issues there for sure. The payback is quite rapid in a situation like this where he is relying on diesel power. I am an amateur in the true sense that I love my work :-)I have installed quite a number of low budget hydros and they don't always look slick or professional. But they do the job and deliver low-cost reliable electricity.
This was originally a diesel generator powered site. I helped the owner to install hydro and I supplied the inverter. I believe that the hydro can displace most if not all of the diesel power but I hardly ever hear any news and am not sure how effectively the system is actually managed at this time.
@AlternativePowerMan The rocks were beign sucked in through gaps in the pipe joins because the turbine was being shut down by closing the top end of the pipe and this created a vacuum.

I better start planing if I want this to be my next project... great video..
Hello Hugh. I am a big fan of your work. I bought a video 20 years ago on making a windmil out of a truck axle. I came up with my own system and I have been charging batteries that run my refrigerator. I have it on youtube too. Search Working home made hydro Generator/ Runs two refrigerators free electricity
I have another video showing how I make it. I start with a new axel that is used for trailers.
We did some work on the pipe joins and I don't think it happens any more. The turbine is by ecowavesystems
Thanks Hugh!
Very useful advice!
Banki hydro, beauthyfull. Debrys are a problem. Clean water after. Great.
Nice setup there!
Look at the video at approximately 1:minute. THe rock and debris level in the pond is almost to the top of the sluice inlet. This might pose a serious problem. I stronly suggest that someone excavate this to below say 50 cm below the slice gate. THis will form a trap for the crap that always rolls down stream in the winter time.
How and where do we get the equipments used for this Off grid hydro installation?
I am setting up a system that looks close to yours in size and effect and would welcome a conversation on the do's and dont's - I am in Lancashire (N.W.) I have all licenses and I am at the pipe installation stage.
Ok mantap sukses semangat mampir
Excuse me, how much power could it generate?
Love you dog .. America Bulldogg ?? How mutch does IT way..
My Charlie did 82kg Nikita did 72 and Troll 93kg
whats with the arctic peregrin?
Trial and Error, a love story
Is that a Peter Lister diesel two cylinder air cooled generator?
we are a small community in the philippines and wanted to have our own hydro generator as we are based on a small water source we are very interested to know how much the total cost for the whole system, better yet if you can also provie us to where we can get also them.
that's why you need forbay for sendimentation
you must use a dipper type of propeller sir
Could you tell me some technical data:
- total fall;
- turbine type and where can I buy it;
- etc..
Thanks!
This is a low-head site with about 4 metres as far as I can recall. it was a few years back and my part of it was basically the electrical side. The customer did the "civil works" along with the digger driver and hence the creation of a vacuum that sucked rocks in through the gaps in the pipework somehow. The turbine was from ecowavesystems.co.uk/ and a very professional job. Controller was by www.sustainablecontrol.com
He had enough water to do a flow over sluice. Would have kept the rocks out of there. Not a good design on the intake side.
hi John, sorry but you don't get the picture. The water entering the penstock came from a nice big pool (fed by an washover screen) and was clean, but the client did not buy a valve for the bottom end (expensive) so it was controlled by closing the top end of the penstock. It turned out that he had not done a good job of joining the pipes and when the flow was stopped it created a vacuum that sucked small stones in through the gap. It took a while to figure this out (thanks to Jamie Wallace how had seen something similar before) and dig up and fix the loose pipe connection. Since then it has worked very well for many years although the falcons have sadly departed.
Hello can i ask what type of motor they used for mini hydro.i want to build mini hydro for the future.thank you
This turbine uses an induction motor (most common type of motor in the world) with 3-phase winding and C-2C capacitor network to give single phase AC output stand-alone. YOu need a voltage regulator unless you are running it into a carefully sized fixed heating load. Electrical controller was by Sustainable Control Systems. this includes the capacitors and regulator. Excess energy is fed to hot water and space heating.
Hugh Piggott thank you sir
Hugh Piggott do you need a recirculating hot water tank for your dump load or can you just go to a larger tank depending on calculations? Thanks
In this case I used relays to transfer the heat from one tank to another and finally to a panel heater. The relay coils are wired through thermostats. When the water is not the relay coil turns off and the current is diverted to another load. it works well but you need a lot of wires!
Hugh Piggott thank you for sharing your knowledge sir.it was a big help to us.because it was not easy to pay electric bill here in my hometown.
The water has a lot of sand and rocks...... do yo nao today???....... By
hi
The sand and rocks were drawn into the pipe by the vacuum created by putting the valve at the top, and not having a vent. This video is supposed to be a helpful illustration of how not to do it that way. The pipe was dug up and fixed together properly with no gaps for entry of debris, and they put a vent on it I think, or put the valve at the bottom. Either way that issue was fixed and it has worked really well ever since.
Hook up some gravity batteries, they hold charge forever. look up "gravity Battery" awesome idea.
The best :)
I see a lot of things safety wise that trouble me.
Standing under loads, and that uncontrolled discharge of water in the turbine house 1:48 could have easily damaged the building and causing an accident.

좋은 자료 감사합니다. ( renewableenergy/47784 )
I know how to take the rocks out of the pipe...
I recommend starting the video at 5:50 (the end!). Nothing to be learned from this video
It's not intended to be a technical training video. It's a real life story. Actually there is a lot to learn but I you need to ask the right questions or read the comments and my answers to them to get some of the background to it. I am not making money from this so you can take what you want from it or go elsewhere.

1:48 WTF ?
At 1:48 they were flushing out the pipe to remove stones that had been drawn in by the suction. The closure of a valve at the top had sucked stones and debris into the pipe. This was sorted out, and then the pipe was being flushed out to clean it. I have to say that despite the alarming events portrayed, this system has worked really well ever since. The pipe design and installation by the client was the initial problem. The lesson to learn is that closing a valve at the top creates suction which can draw stuff into a poorly sealed pipe at low head. I regret that most viewers do not seem to read the notes and understand this.
@@scoraigwind Ah, thank you!

No narration as to what's going on!?!? Waste of time watching! Plus, what the heck does hydro installation have to do with that damn bird?! Unbelievable!
Couldn't have said it better myself. Loved the gravel in the pipe too.

you don't have to watch it. sorry for wasting your time :-)
Do you have a channel where we can learn your superior methods ?
here is some very very very late information for you and your subs. the design of the turbine seen here, like the design of an ossberger turbine that it resembles, is Seriously Flawed. and Should Not Be Copied. assuming that a true cross-flow design is desired, certain factors dominate: a certain minimum rotor radius is necessary; perhaps, one meter; the width of the rotor is determined by the flow rate; the optimum number of rotor vanes is, perhaps, 23; the optimum operating speed is, perhaps, 20 rpm. a cross-flow turbine is, essentially, an enclosed overshot waterwheel. cheers
Thanks for that opinion, David. There are plenty of small, higher revving crossflows like this around, and they work well. I am not in any way prejudiced as I have never sold one or installed one or made one. (My part in this job in the video was on the electrical side.) But I recognise that they have their place, and I think your comment is overstated. In my opinion.
well, thanks for sharing. cheers
David Davids why? Is due to air layer, cavatation, etc? And, for the application on the video would you recommend a bulb propeller setup or something else
why, what. my comment relates only to the hydroturbine. without knowing the head and flow rate, analysis of the site is impossible. cheers
David Davids your commenting on someone else's video to all their subs that the design of the turbine is flawed. You give no argument to why it is flawed, only state how it should be. What causes these flaws and what are they?
Nice setup there!
I have a river with enough water can I install any turbine on river?
