New type of pump without electricity or heat engine

[didier33420]

Good morning all . This system seems to be based on the Durozoi "water engine" !!!! Durozoi had developed what he called a "water engine" which was in fact a water elevator just like the hydraulic ram. A very complicated machine, with a lot of moving parts. I don't know if this machine has been very successful !!! I cannot tell you that it is the same machine, but .... it looks like it !!!!
By digging a little on the internet, we find a sketch of this machine from Durozoi. This industrialist also manufactured hydraulic rams. The town of Castillon the battle in Gironde was equipped in 1900 with two large rams "double water pump" brand Durozoi. These two rams supplied two water towers which in turn supplied 40 public fountains throughout the city !!!
Have a lovely day everybody ...
Cordially .

Good evening, here are photos and drawings that didier33420 sent me by mail, at his request I publish them here

pictures of Durozoy hydraulic rams

here is something to read and see the inventions of this gentleman
there was also Jean Charle Gelly who designed this type of pump formerly
didier33420 may be able to tell you more or marcillat

Hello.,

Remundo,
did not have time to read the pdf at the head.
Is it true science and technology, or even a story that creates energy "nothing"?

Not from nothing but a big waste of fresh water to use its kinetic energy.

Even if it works, it is ecologically disastrous, because everything predicts that fresh water will be the crucial problem already present in some poor countries.

Hello,
What is the advantage over the ram pump?

The pressure can, depending on the multiplication coefficient, be much greater, and the whole thing quieter.

Hello,

It's interesting. If I understand correctly the operation is similar to that of a pump Aries to know that the energy necessary for the operation of the pump comes from the gravity of the water, otherwise it requires an external source of energy.

It would be nice to have a small schematic film (gif) that details the operating principle, because I have trouble seeing how the pump works in detail.

Otherwise, there are very old pumps with single piston system and double compression chambers, but they need a source of energy.

At the limit, if we want these types of pumps do not use any source of electrical energy or heat, we can imagine that the wheel that actuates the piston is driven by a paddle wheel in the stream of water.

Here are 2 old pumps that I recovered and disassembled to see the system: 1 central piston with 2 compression chambers and valves. Note that the piston seal on one of them is provided by 2 thick washers in ... leather!

In the last sketch we use freshwater collected at height that is thrown back to the sea (at sea level) to pump salt water only for the purpose of air conditioning.

It seems to me that it is a waste of fresh water?

The idea of ​​recovering the condensation water on the cold pipes is interesting, but what volume compared to the water wasted?

The freshwater caught on a river goes anyway to the sea. In the example given, it is raised to the surface at a chosen altitude.
The cold water used for air conditioning can be partly heated (solar) for thalassotherapy (the water 900 meters here in Reunion are 20 times more mineralized than that of surface.The farms of bivalves can be economically interesting.

Is it true science and technology, or even a story that creates energy "nothing"?

it is still a while that we know how to use the gravity energy of water.

To put it simply we could build a turbo-compressor, with a Pelton turbine for example and a centrifugal pump on the same axis?

In Reunion the fresh water is rare and rationed, depending on the season it is cut off from 22h to 6h in the morning, the wisest would be to store it as high as possible ...

The goal is precisely to store it as high as possible, to go up 400 meters a pelton coupled to a centrifugal pump
will not reach 400 bars at a minimum.

will not reach 400 altitude meters, as can our volumetric pump.

Remundo,

it seems to me that this pump uses some of the energy of falling water to raise a small part.

the more we want to raise the water very high, the less we can have the flow that goes back.

400 meters that makes 40 bars ...

You can put as many centrifugal pumps as you want in series (stacked on the same axis) to increase the pressure.
