Strangeness at the bottom of the garden: 100-ball quiz

[Capt_Maloche]

It is a goat to mount a winch ...
there is a good chance that it is a concrete water supply fed by the stream nearby, the structure would have been created to fix a pulley in order to draw water like a well

Is it a bodyguard for a pool?

Question: you dug a little in the "well" to see a little?

[Obelix]

Hello,

For my part, I lean more for a little clever who has circumvented the ban on tapping directly into the stream by digging a sump surmounted by a structure allowing him thanks to a pump to fill the basin ....
Can be low flow solar or wind pump!

Not Maloche dug but I believe that the "well" only serves as a foundation for the structure ... There is no water at the bottom except after a heavy rain ...

For the ram I don't think it takes such a big drop ... and I will try to prove it to you. Obviously it takes energy ... but for that there is the flow which is not so low.

So a flow can be converted to a certain extent into pressure ... am I wrong?

Come on, I give it to you because I like you

[Christophe]

There is not enough (practical) info on your page Remundo ...

Otherwise I just think that the 1st owner simply put an empty cellar pump at the other end of the pipe to fill his reserve from time to time ... there is a vestige of a power outlet not far away which would confirm this .. .

hello christophe, I can tell you after putting a lot of interest in the ram, that a difference in level of 1 meter is enough to start a small ram and go up 65 to 70 percent of the water that passes through it.

At the time I had made tests with a small ram in pvc, diameter of the inlet pipe 40m / m, fall of 1m, raised water over 3metres with a pipe of 35 at the outlet.

then I moved and I don't know if the new owner has completed the installation.

So for you by putting the pipe in the river bed by calculating that there is flow and the fall of minimum 1 m, it will have to go up the water in your tank on the structure missile launcher.

Ah well here, thank you for confirming my thought tigger ... especially since you saw the stream in real life . Your help will therefore be welcome for this "project"

Considering the size of the stream I thought to put a larger collection pipe ... 120 mm style that I gradually reduced to increase the internal pressure and "simulate" a fall (0.1 bar we should get there without problem). ..

I spoke too quickly Remundo, your site is complete but you have to start on this page: http://www.codeart.org/technique/eau/be ... que_fr.htm



ps: I am still bloated by the yield of 70% of a ram ... finally this is what is indicated on the formula ...

[tigrou_838]

hi tof, exactly in the 70% when I had done my system, I have more time, but look in 2005 or 2006 we had talked about the ram a lot of time.

why want to reduce the diameter of the inlet pipe, you compensate by lengthening the pipe in the river bed, oops river.

the most important is:
that the entry level of the pipe is at least 1 meter above the level of the ram, in addition if you put the ram just in the hole which is on the bank (50cms to 1metres above the river), you will be able to bring water up to your 70m3 tank without problem,.

well, do not expect a rocket or pump flow of 650watts, but over 24h it will do a lot of water, quietly and surely.

in addition no electrical connection, no breakdown, etc.

We can see that a fall height of 1m can go up to 7m of water ... so a priori it can stick in my case Just make a capture assembly that makes 0.1 bar ...

Easy I think given the conditions ...

ps: I am still bloated by the yield of 70% of a ram ... finally this is what is indicated on the formula ...

Mouais .... One easily finds on the net of the values ​​of output which turn around 20 to 30% maximum ....

So where does this 0,70 come from? ... No desire to dig but it is certain, 70% is impossible.
