Ram manufacturing

[Rabbit]

I have not found or we are talking about an anti return upstream of the ram
on this link but the idea seems good to me. I wonder despite
everything if this non-return will not brake the water that feeds the ram.
or then place an anti return on dimentioner to limit the
resistance.
Next to your Youtube link to your previous message I have
find this pump which seems interesting to me. I wonder
how was the Aries anti return done and how is it
rule.

good evening sorry i was mistaken i thought i saw that on a forum, in fact I found that above, it seems to be a variant of the ram http://sentinelkennels.com/Research_Article_V41.html

I even opened a special subject on it

Ave.
But if we keep an inlet pipe say 50mm, and we decrease the outlet pipe, we would have a greater flow

hello, it is a good idea to use a tuayu of battery of a larger diameter and before the ram a reducing connection, one obtains I think a similar result with weak difference in level that, with a tube of normal diameter but must go up in denivelation

hello, I put a French link on the ram with a flapper valve but apparently there are no plans, or how to modify a flapper valve in pulse valve

it’s fine to show something but it’s where we show it right or not at all

Please try to show a little more interest in these topics, as sometimes I feel like I'm talking to a wall here, I've already alluded to it on another sling pump topic.

I am trying to bring something to the forums so don't just lean on my back, otherwise i will soon be asking to be paid for the research i do

good evening, here are two videos of hydraulic rams

you may have noticed the similarity between these two videos which is also an anomaly, tell me which one?

we will see if you are attentive, if you do not find you will be entitled to a clue, try your luck

hello Oli,

I give my tongue to the cat ...

good evening, a clue

the water can not be compressed so something will have to be done to obtain "air" pressure.

[dedeleco]

The ram uses the kinetic energy of the water launched at high speed by abruptly changing its path to go up the slope higher than its starting point, but in less quantity, in a pipe of smaller diameter, like a truck launched, then diverted which goes up a slope to stop, and the water on its momentum pushes that which goes up by force in the small pipe.
The ball or vase is not essential, but then, without shock absorber the shock is very violent and can break everything, hence the non of ram !! And we lose a lot of energy in this shock by irreversible deformation, and therefore low efficiency.
The cushioning balloon decreases peak pressure and max height, but with better efficiency. The valve hysteresis is also important.
On the video the plastic seems patched up with scotch tape after demolition with a ram!
The deformation of the pipes which absorbs the shock plays the role of the balloon!

the lack of the "balloon" was that the anomaly on the other hand here is a ram also without a bell

the elasticity of the pipe plays the role of the balloon

here is an interesting system to renew the air in the bell

and this other link with a ram with this type of air pump

the beaume-Boulogne model, this system replaces the breather which makes the ram lose power
