Bellissimo video, consigliato a pieni voti da me e dalla mia prof.
Thank you
Nice, such "Kraftwerkian" music with it. So appropriate!
Can this be powered by Steam?
As a mechanical engineer, this is really fascinating stuff. At what head does this turbine operates at? And at what RPM?
Head above 200m
Amazing sir❤❤
this music is like... so good
Sounds like Kraftwerk. Which is funny because that means power plant in german
It would be a little better without the constant THUMP!......THUMP!......THUMP!......THUMP!......THUMP!......THUMP!......THUMP!......THUMP!...... At least, in my opinion.
Anybody knows exact name of song
Я бы сделал отбор воды не с внутренней строны кольцевого коллектора а с внешней стороны, затем сделал бы поворот на 90 градусов и эффективность потока воды увеличилась как минимум на 40%.
Thank you sir
Where is the water exit??
The water in vertical Pelton turbines are leaving at the bottom of the housing into the tailwater channel. This means, the water on the upper half of the runner is redirected via the central cone and the housing outer wall to the lower side of the turbine.
The Backrooms
what software used for this animation? thanks
name of song please
Is there a small size that produces 5 megabytes ... or one megabyte? How much does a cubic meter of water need per second ... and how much is it worth in dollars ...
Dear user,
Thank you for your question.
Yes, there are machines with 5 megawatts. They are considered as small hydro and are successfully marketed by Voith Hydro.
The amount of water required for a given output depends on the head at which the water is supplied. In other words, how great is the difference in height between the source of the water (where the water is collected) and the powerhouse in which the turbine is located. In the turbine, the potential energy stored in the water due to the head is converted into mechanical energy (rotational energy) and then into electrical energy in the generator.
How much can actually be earned from the sale of the energy depends very much on the market. Pelton turbines are very often used for peak load compensation or even frequency regulation. These are usually the best paying markets. However, it is not possible to make a general statement about the revenue.
Yours Voith Hydro team
But now we use them with Ram Pumps bc there's Zero fuel zero electricity to run them!? Are used to create mini generators at home
function
Thank you
What is the function of ejector???
Could be used this turbine also with steam of an atomic power plant?
No
Good Morning Sir,
Bellissimo 🙂🔫
Rispondi bellissimo e poi metti l'immagine di una persona che si spara in testa!?!?
@@ercoma7020 *IRONIA*
Hell yea
ok
🎉😂❤
Yeah... No narration, same perspective. That was a waste of time.
Why are there no multi stage turbines ??
Answer the tech is available from RDP MARINE AUSTRALIA
The techs will say the issues are turbine surging OR to much backpressure OR the dissolved gasses issue ALL are nonstarters
So were is the price drop you can have by fitting this item ?? YES YOUKNOW WHY
?

Hydro electricity
The Frozen technology
An open letter to the world
By Simon Bowman
Australia
Since the beginning the growth of hydro science has been slow and we have made very little forward movement in the past 40 years.
The ideas that might make it leap forward with more efficient use of the water are stifled by education being thought of as immovable .
What was wrong yesterday will be wrong forever and new tech can't get around a problem.
This is not a problem solving mind set
Australia has forced many an idea to leave this country to grow
just because we have an issue with new ideas
A classic example was Metal Storm a new type of fire arm that had no magazine and no brass cartridges to hold the propellent.
all the bullets are held in the barrel and with this configuration the barrels can be stacked this gives it a rate of fire unmatched anywhere
It had to leave Australia to become a product or stay and die.
This I fear is the same story about to happen with the hydroelectric field
Since 2016 RDP Marine Australia has been working on a system that can be retro fitted to all dams with tailraces longer than the turbine hall needs so it has to deal with a backpressure higher than is ideal creating a loss that can now be recovered
At this point it should also be noted that the inventor asks where is it written that water storage dams can’t make hydro power to ?
So is this inventor saying “This is the answer to all ur power needs?”
No of course not but like all good things it is a part of a solution it will fill the gap for base load green power
Lets not forget at the location where these units will be fitted has most of the infrastructure already in place to build the system
NOW TO THE ISSUES
There are three main issues right of the top that are the most commonly raised as why it will not happen
So lets stomp on them straight off
1, fit an item into the tailrace and backpressure will rise in the turbines
No this is not true as a this system if done right it can be fitted to be like a tuned exhaust for a car
2, There will be to little back pressure so RPM will not be constant
Again No if the system is correctly fitted this to is a dead issue
3, Dissolved gasses that are held in suspension
This is a minor issue and most chief engineers are well capable to work with this
4, NOW this one can be a deal-breaker it is to do with a what if question.
So what if the new set of turbines go down or just one ?
Well if one or all freeze up the main turbine hall will be unaffected and no issues flowing up hill
These four issues are the most common reasons I am told No
It is this closed thinking (knee jerk response) to a new idea from the same family of being blinded by their education that stifles the industry moving forward
The one question I have no answer to is time
How long to install?
How long to service the new turbines?
To service time i still don't know but the system is set to allow a swap out setup so actual down time for that turbine slot is less than two hours and the rest of the system remains running during the swap
How much will it cost?
I can guess only the price but the price is not so high as to be to costly
Whats its life span?
Well with servicing I can see it giving service for the life of the dam
NOW the big question Money!!
this is a fluid issue shall we say the rate changes and i have stated previously money values but the income is in two parts the improved tailrace efficiency and the second bank of turbines should be close to 10% extra income
The one main issue I find so wrong is the time line needed from this point to the world seeing a working unit.
The tech is there to make it
The skills are available to hire
The market is in need of this item
But the price will rise with demand as the population is getting bigger but the book keepers are happy to see it remain as a rare item with a limited output that pushes up the price
The first adopters have always been the biggest winners I wonder in this area if it will be the big four or will a player from left field run on and wipe the floor with the rest standing with their hands in their pockets confused as to what just happened
Well, I hope this has given you food for thought and made you pause your thinking and look into what I have said I do not expect you to just except what I have stated as fact nor do I know it all so I can learn a new thing to.
Please pass this around let the open minded look it over and pass judgment after all the driver in the end is the need and the ability to see what is needed down the road is the saving grace of the human species to plan ahead
If you think i have missed a point or you have questions please comment i will respond well within 24hr and as i have said many times i don't know it all and you never stop learning
@@donaldbiden636 All dams run one main turbine hall this will let you have up to three same flow rate same dam no issues .. So why are you ???????????? you need to be a better communicator not just ?
@@simonbowman6206 what are you yapping about
@@donaldbiden636 don't worry it's ment for educated staff in the industry explaining it would just be a waist of my time as U wouldn't understand
Pitiful that you provide horrible music when you could be informing us about your capabilities. It appears an adult did NOT review this video prior to release. Best of luck!
What's the point of this video when Pelton wheels are an Ancient technology?
👎Nico animáción but no facts
It is not workable. As when it rotates at high speed it will scatter the water rather than increasing speed or making work. Like, at max Rpm wheels of car etc looks like they are not rotating. Then, water makes the wheel to stop rather then helping it to work. Creating a stopper. Tell me if I am correct or not.
The Pelton bucket is designed in a way, that the water jet enters the bucket in the symmetry plane where it will be divided into two half for the left and right side of the bucket. The water is then redirected by almost 180° and is then discharged, so that it is not in contact with the outside of the next bucket.
The design of the Pelton bucket profile is optimized to serve this purpose with the minimum possible losses during the entry, the path through the bucket inner side and at the discharge.
Hydraulic brakes have a completely different design, where the profile is used to generate as much losses as possible. The design challenge for effective brakes are typically the lifetime as the increased losses produce cavitation that will then destroy the structure and leas eventually the failure of the component.
The Pelton wheel has been used for high head (pressure) applications for 140 years.
But you are right it doesn’t work…
@@VoithGroup just a simple experiment it won’t work. As attending a max speed you to stop water and when it reduce you again start the jet. And, you can’t let the jet all the time. It make a disaster and useless.😇
