Pulser pump or pump geyser

[oli 80]

Hello, I noticed that the forum basin and pool irrigation is saturated with eco-friendly pumps, hydraulic ram, lifting siphon, strange pump, etc.

here is a pump created by a Canadian the pulser pump here is a link with videos
http://nxtwave.tripod.com/gaiatech/pulser/index.htm

and here are two videos of tests made by people other than the Canadian inventor http://www.youtube.com/watch?v=oxJTC77PADQ

http://www.youtube.com/watch?v=Tf1-7fL_UIk

the second video is very recent and much more explanatory

hello oli 80
exelent this pump a bit on the same principle as this one
but with a natural and free air supply

[oli 80]

good evening, this pump also seems quite simple to carry out, moreover there is no check valve, because the water is discharged continuously as long as the vortex of air is maintained in the water inlet pipe, as I understood this pump was originally a model of a natural phenomenon called crystal geyser of water engulfs in a small gallery a resort part below and with the air part comes out of this "geyser" of cold water

use a natural phenomenon as a pump not bad, unlike the ram I don't know how high the water can be pumped,

hope this topic will be of interest and I encourage all those who want to try like this young Englishman from the second video to build this fabulous pump

This principle has been used for years in aquariums, especially when you have a filter under sand or a skimmer (saltwater aquarium).
It is also the principle of underwater vacuum cleaners used during archaeological excavations (reminders on certain episodes of reports of the late Cdt Cousteau).

hello, the pulser pump system does not need a compressor or a "bubbler" air pump for aquariums,
the air supply is made naturally by the "trunk" a bit like here on this blower http://moulinafer.free.fr/Vent.htm and this site
http://books.google.com/books?id=RRwAAA ... pe&f=false page 240 fig 196

whoever created the pulser pump also did this http://www.altenergymag.com/emagazine.p ... =coffeejar his name is brian white

these are "low cost" systems that can easily be achieved, I encourage all those who want to try these achievements, I can not too much space and no stream near my home

good evening, here is a site with figures and an assembly plan with videos of the device in operation
http://www.appropedia.org/Pulser_pump

we can see the movement of the air in the transparent pipes, we also see the simplicity of this assembly which will interest more than one

The bubble pump has been used in absorption refrigerators with heating instead of an engine since the 1920s (Einstein Szilard patent)

this last link gives the conditions for the bubble pump to work properly:

It is linked to the surface tension which causes bubbles.

good evening, here is a theory that seems possible to me, we take a tank with two openings, on one we put a pipe on the other we mount a check valve and a venturi with an air supply tube, of course opening with the discharge pipe must either have a dip tube or must be at the bottom of the tank

operation

this tank is immersed in a pond or a deep stream, the water enters this tank by the venturi which sucks air through its supply tube which goes to the surface, the air and the water enters the tank this will give a compression effect with the depth, this way we would have a natural airlift using the pressure of the depth, the more we descend the more pressure

it is a system that remains to be tested, brian white was already working on such a system, if it works we would have an autonomous pump, but hey all this is only theory

[dedeleco]

It works very well on videos with the air entrained at the bottom with a lot more water but the compression of this air released at the bottom will not be of great help, because when going up it decompresses and therefore does not exert much pressure to go back higher than the starting point.
On the contrary, the air that rises in a small diameter tube (around the cm) is due to the effect of surface tension in alternating air and water sections. This column of much lighter average density rises by Archimedes, much higher above the starting level in the inverse proportion of the ratio of density water air in the tube divided by the density of water without air !!!
To balance the pressure at the bottom of the air bubble tube, you need a height of water bubble mixture in this density ratio!
It is exactly like a light fluid (oil) must be higher to balance a heavy fluid (water)!
So the higher the proportion of bubbles rising in the tube, the higher the rise height! The bubbles must go up, entraining the water trapped between the bubbles but not freely, leaving the water in place! For this reason the surface tension ensures this entrainment effect with bubbles occupying the entire tube as long as the tube is not too large in diameter, theory given in the bubble pump of absorption refrigerators.

Figure 3-8 with suppository bubbles on the whole section of the tube is good and not the boubka figure with small bubbles in the pipe which cause nothing!
By respecting this condition, it is not only theory, it is sure that it works !!!

The tests have been done and it works on videos like Archimedes !!

hello, has anyone ever tried to build the pulser pump here?

I just know that padawan said he made one to present at the science fair, here is a realization that is not yet developed http://www.youtube.com/watch?v=LungrknZtic

and the site with the maps http://www.appropedia.org/Pulser_Pump_Engr305

it would be nice to have a pulser pump made in France

good DIY to all
