微水电建造

该项目进展缓慢。  我是用一个2匹3相电机。我去的阿美特克38伏有刷永磁电机,这是我的风力涡轮机。风暴把它从今年春天。打破了叶片中的一个,所以我没拿时间来修复并重新安装。是很好看,再加上我有一个备用。我已经下到我爸的很多今年。他是81,所以我上班坐在拖拉机上他。上工作了很多过去的每一年。我不知道哪个会先来。他或农场全部A 100。他正在努力他最好使它的拖拉机。他已经有它超过40年。虽然我帮他清理漏油的方法(2)我们的湖泊几次。地段的雨水和其他的东西。只有一个已经运行过,除非下大雨,仍然有足够的水,以填补6''管离开湖边。正如我在过去曾经说过,我打算使用3吋或4''管。也许3'' 2运行2个单位。水变低2,关一关。大坝的最低点约100英尺运行。(+ / - )我有分寸的。我还没有测头,但它是大约20到25英尺。也许30英尺。这是我为我的第一次考验。它看起来并不像很多我知道。我会画它,使它看起来更好。它将被安装到躺在它的身边工作。我会为电机罩,以保护它的元素.. 我测试的角度与最佳/最快的旋转空气软管,这是我所知道的唯一的方式得到一个起点。用螺栓和垫片一些,如果需要,我可以调整角度。刀片是塑料风机叶片。我已经看过很多事情,这看起来是有希望的。这就是不买东西给它做。这是6 1/2'' 3'',我使用的是风力涡轮机在同一个凉棚。该管道是1 1/4'',它夷为平地,在最后做出一个喷嘴1/4近3''宽,我会从3吋或4''管下降到1 1/4 ''在最后。我有很多方法可以尝试,使1/4''壶嘴更大或更小。靠近或远离父亲。更大的管嘴或更小。不同的电机/一族。我将发布更多的时候我得到安装的东西。安装过程可能需要一些时间。就像我说的这个是缓慢的。感谢您的帮助和关闭的电路板给这个项目

This project has been slow.  I was to use a 2 HP 3 Phase motor. I went with the Ametek 38 volt brushed PM motor that was my wind turbine.A storm took it out this spring. Broke one of the blades so I did not take the time to repair and reinstall it. Was nice to watch.Plus I have a spare.I have been going down to my dad's a lot this year. He is 81 so I work on his tractor for him. Work on it a lot more each passing year. I don't know which will go first.Him or the Farm All A 100. He is trying his best to make it the tractor. He has had it for over 40 years.While there I helped him clean out the spill ways ( 2 ) to our lake several times.Lot's of rain and other things. Only one has run off unless it rains hard.There is still enough water to fill a 6 '' pipe leaving the lake. As I have said in the past, I plan to use 3'' or 4'' pipe. Maybe 3'' with 2 runs for 2 units.
Water gets to low for 2, Shut one off.To the lowest point of the dam is about 100 feet run. ( +/- ) I have measured this.I have not measured the head but it is around 20 to 25 feet. Maybe 30 feet.This is what I made for my first test.

It does not look like much I know. I will paint it to make it look better.It will be mounted to lay on it's side to work. I will make a cover for the Motor to protect it from the elements..

I tested the angle for the best / Fastest rotation with an air hose. It was the only way I knew of to get a starting point.With the bolt and some shims I can adjust the angle if needed.

The blade is a plastic blower blade. I have looked at many things and this looks to be promising.That is without buying something made for it. It is 6 1/2 '' by 3''.I used the same arbor that was on the wind turbine. The pipe is 1 1/4''. It is flattened out at the end to make a spout 1/4 by near 3'' wide.I will go from 3'' or 4'' pipe down to the 1 1/4'' at the very end. I have a lot of ways to try.Make the 1/4'' spout BIGGER or smaller. Closer or father away.Bigger pipe spout or smaller.Different Motors / Gens.I will post more when I get the thing installed. Installation may take some time. Like I said this one is SLOW.Thanks for the help with this project given on and off the board.

I used a tin coffee can. The end fit right in to make the side wall.I cut the can sides to fit inside. I cut a small tab to lock it in place.Used silicon to glue the end plate on. Plus it will hole the in side plateso it wont try to move.

The object of this is to see how much power I can make with what I have and what I can put together.LOVE :The little things one can learn while doing it. What fun would it be to just buy and install the best.
I may be wrong but I'm trying to get all the force or push out of the small amount of head I have.I may add a second spout / nozzle.I have the flow but not much head pressure. So I was trying to meet half way on it.I don't think I can't get much speed from the pressure of a 20 ft to 30 ft of Head. I will messure it next time I'm down there.I could be all wrong own my thinking. What is the most static pressure from 20 ft to 30 ft of Head ft?If the head is only 20 feet 100 feet pipe 4 inch pipe With this length the optimum water volume you may use is around 120 -130 GPM This is the amount of flow I have. I have measured it. The watts that can be generated :  head * volume * 6 = 6 * 8.2 * 6 = 295 watts but due to the low head the expected harvested power looks  like  NOT more than 180-200 watts, ( the volume used reduces head for about 1.5 feet )Information is from another source.ThanksI can see using this to it's fullest in the future. But for now I will be glad to get a few watts or what ever I can get.One thing, once the pipe is in place I can try other turbines.

OK I had to move the 8'' spill way pipe that I put in a few weeks back.
I moved it 4 ft over and added 20 more feet to total 40 foot of 8'' pipe to the old spillway ditch.
Everthing is now out of the way to make a nice but small yard for the camper. I will have to
have some dozier work done to make it ready for the camper. Need a bigger place for the camper
and make the old road to it wider.
I have a T to fit the 8'' pipe that I put a 4'' connector in line with. Good part is I can add pipe to the upper
part of the T to raise the lake level.
The water supply this year is not even enough to run the unit even if I was ready to install it.
It has been HOT and I mean HOT and DRY here most of the summer.
Here is the test frame I made to hold the 1 HP EMC Motor / Gen.
I know it would not last but I will paint it good and use it to see what power I can get.
[ Specified attachment is not available ]
Here are 3 runners I made for testing. Not going to buy a real one until I set the camper up.

I missed placed the 6 inch runner photo.
Next is the nozzle and mount. Nothing more than a 3/4 cap and nipple.

The best part is I took three 60 watt light and hooked them up Jerry rigged.

The gen is just laying there and does not try to rotate until it gets above 70 volts.
Then I have to hold it lightly to keep it from turning when it is at 120 volt. All there lights are at full power.
I checked the RPM and it was at 416 rmp at 120 volts, 180 watts AC.
I have did a little testing rectifying it to DC and it takes a lot more torque to just get 8 amps DC.
I will do testing it as DC and post that later.
If anyone knows of that testing to a 1 HP EMC motor already done please fill free to add a link here to it.
Yea, I had trouble with the photos.

Dam thing timed out before I posted. I am a slow typer.Had A nice post typed out. So now I will give the short version. I hate doing $#|+ twice in detail.Next time I will do it in note pad first. All the time I need there. Killed the mood.Tomorrow I will do testing. Today was harder that I thought to get just 100 feet pipe down.For now it's still a 12 volt set up.Around 150 feet to the battery bank is the plan.
Boy, I hope my Hydro works better than my post.

First test is in. Emc with this.

Nozzle 3/8 times 4. I know I could have got the voltage higher but this is what I stopped tuning at this voltage.I will now buy a real runner. I think I can get it up to 120 volts ( Unloaded ) with a real runner and play with the nozzle size.Then to get the transformers. Frist to see how high I can get the voltage.

I tried it Jerry rig rectified and it stalled.

I did try my 36 volt DC motor set up.I got 300 ma while hooked to a light and left it light in a tree on.
