Pulser pump (water pump or low pressure air) and syphon pump

[gaiatechnician]

You can find info on the pulser pump on my pages (google search for my pages or in the internet glossary of pumps from someone else ). They do not make electricity. My site wasn quite big enough to make a really nice pump but I pumped water for animals for years. I washed the silt out of fine sand for masonry, and piped air down a chimney to capture the heat there and return it to the room and used it to oxygenate animal manure (useing the low pressure air).

Pulser pumps are below ground but I have also made syphon pumps which require no digging. You might like to try them and post pictures of your experiments.

On my pages, there is quite a lot of info if you check through them.

Best of luck

hi Brian,

you can post the URL of your webpages by adding http:// to the name of the page,

the full URL can be copied from your browser address bar by highlighting the address, right click, and select 'copy' from the list, you can the paste the URL into the text of you posting by right clicking again (on your posting text area)

e.g. the URL for your poating is;

I'll google some for you pages

all the best,

Well that's certainly some interesting info! Might have to give this one a try...

I think the URL's he's talking about are:

Fun stuff

Hi Brian,

I have thought about this.  More with powered air.

Could the lift be greater with a 33% reduction in the output pipe, at about 33% up?

Then another 50% reduction at 67%?

More bubbles per volume means more lift.

The numbers are more representitive than math.  It's been a couple years.

I did not read all the links. I'm afraid you will vanish before I digest it, like so many others with an idea I would like to follow seem to do.

Monitor mining pump type idea (+KE).  Or a Monitor, in reverse (-PE).  Depends on the line of thinking maybe.

Thoughts?

For frequent readers.  This is related to the fish killer water splitter thing, indirectly. Very indirectly.

A bubble maker that takes only 90ma @ 12v regaurdless of pressure.

http://groups.yahoo.com/group/pulserpump/ gives more info (in the files and photo pages too.  It is related to the fish killer but It is probably benificial to fish in most climates. The fish killer is a deep tromp which dilivers pressurised air to 50 feet or much more deep. This can give fish the bends from disolved nitrogen. A pulser pump like what I have made goes less than 10 feet deep. Nitrogen disolving in water is mostly related to the time the bubbles are in contact with the water and the pressure and to a lesser extent to the temperature of the water. (Cold water absorbs better). I believe that pulser pumps will normally be benificial to fish because they oxygenate and because they remove quite a lot of odour producing chemicals from the water. (I welcome any research to verify this).

I do not think my site will disappear just yet. It has been online for about 5 years and I encourage people to copy it (as long as they acknowelege my work).

I also encourage people to make models and pumps and send pics or emails to me with their results. (The response so far has been extremely dissapointing).

There is work to be done on pulser pumps and on syphon pumps.

You might just enter the science history books if you do it and publish first.

If you have a plastics company, or indeed any company engaged in work in 3rd world countrys, it might be seriously good publicity if you researched the pump and published your work.

I do not believe it is worth the work and money that people spend converting low head hydro to electricity. It is probably cheaper and more efficient and much more environmentally friendly to instead use the energy locally for direct pumping and the other uses discribed on my pages.

Best of luck with your research

the links above are related to the math behind the pulser (or bubble) pump. The last two are for multiphase mixtures in refrigeration (rv propane refrigerator stuff). They greatly simplify with just a single fluid. From what little I can understand of it- the pumping capability is related to the density(bouyancy) of the air/water mixture (bubble density). not sure if a change in pipe size would actually net any improvement unless the bubble flow velocity was high enough to accomplish hydrodynamic change instead of a bouyant one.

any way thought you might like the links.
