Ram manufacturing

[dedeleco]

The shock is due to the fact that the water changes speed and direction, like a truck which cannot keep its speed and its direction.
So, if you climb without a vase, but so that most of the water thrown behind at the closing, does not change speed and direction, the shock will be less. Thus, for that, it would be necessary to replace the valve by a change of the outlet pipe in the axis, passing from outlet towards the outside to the pipe bringing back the water while keeping the same pressure drop (same diameter of the pipe, and in the axis).
This principle pushes to a different scheme from the usual ones, full of elbows where the water turns and which are perfect for amplifying shocks, like a truck which takes turns too quickly bumps on the roadside !!
In my opinion, well thought out to reduce excessive shock and a very small volume of vase, the water can rise very high (with small diameter of the outlet pipe).
Energy is stored at the rate where the kinetic energy of the water flowing in the inlet pipe (avoid air bubbles) and does not need the vase for intermediate storage, if one understands well.

I have the impression that the theory of the ram is very empirical and not analyzed clearly at the physical level (hidden empirical secrets).
There is the ideal basic theory without losses which is the starting point, before shock losses, which is very complex, but with basic rules.
The empirical depends on the materials and is only valid within certain production limits.
The volume of the balloon is not discussed but it is important, compared to the volume of the pipes. A controlled elasticity with low loss of the hose replaces the vase as well, in my opinion, and air is unnecessary to make a spring.
But with the pipe diameters of almost 1m per Bollée, the inertia forces are such that the vase is essential, because otherwise the very sturdy pipe explodes !!!
At the time we didn't have rubber or tires!
We do not talk enough about the reports of pipe diameters, because if the delivery pipe is too large, it will absorb all the water launched, without making it go up high enough!
The theory of econology with formulas that are difficult to read (clerical errors) cannot be used to see clearly.
The volume of water launched at high speed into the inlet pipe must be greater than that of the discharge, otherwise the water does not rise to the top, due to lack of water !.
I have not seen this written clearly in formulas that are not very legible, can be misread.

Hello, the site of Régis Petit is quite complete on rams and other unusual pumps. http://regis.petit2.perso.sfr.fr/belier.htm

it is even inscribed on these forums under the name of "petitpetit"
you can discuss all this with him and he can eventually put this on his site

One difficulty is that he studies the existing ram with air bell and ram shock and does not try to see if we can avoid the shock with storage in the bell of kinetic energy, replaced by the search for the minimum of shock, but just a slight change of direction of the flow, never blocked, but which goes up on its way towards the discharge, without having stopped the water launched in the driving pipe. The theory will be different, simpler.

He does not seem to have studied this possibility of avoiding the shock as much as possible, very different, which works at least partially without bell in the videos, which have the defect of not having sought to avoid the shock of the ram.
The ram is a shock like a launched truck hitting a wall and where we store the kinetic energy in an elastic buffer (the bell) which restores its energy afterwards, returning in another direction.
I suggest avoiding the shock and deflecting the truck (or stream of water) in the other direction, going upstairs without suddenly stopping it.
You have to design very different valves that change the outlet direction without blocking the flow, as much as possible, which does not exist commercially.
Since this does not exist, the answer will be that it is impossible and that it is a view of a theorist cut off from practical realities !! !!

the ram is not empirical at all: it is calculated exactly like a cutting power supply in electronics

the long inlet pipe plays the role of the self
the bell plays the role of the capacitor

when the water flows freely in the pipe towards the exit, the speed increases and the kinetic energy accumulates there

When the outlet valve closes the kinetic energy in the pipes and sufficient to stuff in a bell where the pressure is much higher than the inlet pressure: but the speed decreases until you exhaust all the kinetic energy of the pipes

the volume given at each stroke and therefore well calculable

the volume of the bell must be sufficient to absorb this volume: making a much too large bell will bring nothing more

the volume at each stroke depand directly to the flow where the valve closes: if the flow is allowed to rise too high the output becomes bad: too much pressure drop

if we close at a too low flow rate the output is very good but the useful power too low

as a switching power supply there are a lot of parameters to optimize

as a switching power supply, we could regulate according to the outlet pressure in the bell:

strong pressure = no need for water: slow the operation of the ram, only do small cuts at low flow

low pressure in the bell = big need for water: big shot of ram with big flow

it could be done simply by a jack or a frame which acts on the weight of the valve

[chatelot16]

not dedeleco: whether the inlet and outlet pipe is aligned or not does not change much

before the water hammer the speed in the outlet pipe is zero this pipe also constitutes a self: impossible to send instantly all the flow rate of the inlet pipe: it would be like making a switching power supply without capacitor

the bell allows you to instantly take all the flow of the water hammer, and will then take its time to gain speed in the outlet pipes

I had written and I note:

QED.
The ram of habit ...

[oli 80]

hello, here is another type of ram which works a little differently, I had even opened a special subject above
http://sentinelkennels.com/Research_Article_V41.html

here is the link of the subject in question https://www.econologie.com/forums/great-pyra ... t7094.html

pzrfoid believing to have invented something, we re-edit what already existed long before

[dedeleco]

Also stunning the Egyptians and the great pyramid !!
Some have excess imagination and knowing the truth is difficult !!
The ram so true in the huge pipes of the great pyramid is 4000 to 5000 years old (or even 8000 years old?) With obvious traces of erosion by massive water.
This ram is without damping bell, with a structure which took a certain time to find so that it works in demonstration of reconstruction !!
The ram's blow is so strong that it takes a large block of cement or an entire pyramid to hold out !!

Troubling that the pyramid is a huge ram pump imagined over 4000 years before us !!!

The truth is not easy to determine !!

it's like this link of
FRENCH TECHNOLOGY PRESS OFFICE
http://77.72.94.218/us/BlogDetails.aspx?pi=231
perpetual energy, no need for ITER of petroleum or other !!!
or french galéjade!

Otherwise, I persist and it seems to me that we can make the ram without bell and without excessive water hammer, by making the output flow oscillate (as in the pyramid) but without completely cutting off the water flow, but by modulating it partially instead of all or nothing, which is very violent and therefore by partial inertia bring the water up!
To recover the inertia, it is enough to deflect gradually while making go up without blocking completely completely with a shock hyperviolent ram !!
A truck launched on a slope, does not stop suddenly, but by deviating it on a road which goes up, the ram is the same !!

hello, the Egyptian ram made me think of you dedeleco with your system without air bell it is precisely for that that I put this link, besides john gadman with the intention of patenting this design of Egyptian ram , there is a tank but without air and the impulse valve is far from this tank

at the end of the subject "great pyramid pulse pump" I put a link with another theory, "the will of the virgin"

this ram is under the great pyramid a theory of john gadman suggests that the great pyramid was built on it and that the ram would be even older
