Hydraulic Rams

[Tengu]

Such a delightful name...and such a delightful device.

Anyhow, yesterday my friends were showing me over their new land, with a stream at the bottom, and Im thinking `Hydraulic Ram.` (They were talking about water problems earlier, 3 ponies drink a lot.)

And she says `I want one of those pump things.`

Sooooo....my latest request for finding things is a H. Ram.

Obviously there are companies that make them but where would I find a second hand one? Has anyone got one? Can they be built easily??

Why a Hydraulic Ram and not a water pump?...Where does a Hydraulic Ram fit in when moving water from A-B

Also, Cant the ponies just go to the Stream..?

 

[Tengu]

No, the stream is in the woods across the track. The ponies are in the paddock.

Hydralic rams pump water, dont they?

I think you mean Hydro ram, rather than Hydraulic......There's one near me and I'll have a look tomorrow for the maker's name. It's been there for 100 yrs., and will pump water up 300 feet at a rate of 2000 litres a day;
all it takes is an annual change of a couple of washers and has 2 moving parts which need greasing at the same time as the washer change. The performance of these depends on the flow of water through them, or you can build a header tank to feed them. There's a fair bit of information available on line about the principles involved.

Here you go for starters........http://en.wikipedia.org/wiki/Hydraulic_ram

Pumps require external power - hydraulic rams don't.

Theres many different types of hydraulic ram. Mostly of the type found on diggers and suchlike, meaning it uses hydraulic pressure to move the ram and perform various push/pull type actions
when you say "hydraulic ram" most folks (like stevie above) will think you mean the type i just described


What you want is in macaroon's link

.....Hydralic rams pump water, dont they?

Short answer = no.

Longer answer = A hydraulic ram uses hydraulic pressure to press something. Think of a hydraulic log splitter as one example.

Yes, this exactly what i was thinking.

Another option to consider..Archimedes screw. I know these also need a external power source, That's where the ponies come in..

That's the one near me, mentioned above; The only power required for these is the flow of the input water source, have a read of the Wikipedia link above.

Hi

this is the sort of thing they are talking about

I know what Tengu's talking of, and I know of it as a Hydraulic Ram too. Basically the force of water flowing can be used to force a smaller bore up hill….it's maths/physics…no ?

Would make an interesting project to build your own pump.

This has a picture using a calor type gas bottle as the pressure chamber.

Yup, you and tengu are both quite right. Tis just a confusing name

That's English for you!

Yes they can be built quite easily - though some technical know-how is beneficial, I made one a few years ago (I have a video of it running somewhere) from parts that an old work-place was throwing out and some self made bits. When working properly I reckon I could pull a ton of water every 24 hours out of a stream that was no more than a foot wide and only a few inches deep - though it had about a 6 foot head of pressure. There are a few places to gather information apart form t'interweb - CAT, Center for Alternative Energy was key for me, they had a booklet for about £6 that showed every step with a trouble-shooting guide as well which proved to be instrumental in getting mine working.Dick Strawbridge's forum also had some good ideas.
However, mine rarely runs now, due to the stream being very silty and me not paying it much attention over the ensuing years.

Good reading so far. Have often seen them marked on OS maps but never seen them working as such. Look forward to seeing a working model!

They are small things often.

 

[dwardo]

I have absolutely no need or use for one of these but what an interesting read

 

[KayakFisherFinland]

Never seen one before and am absolutely facinated.

Does someone understand the physics so much as to tell me what would happen if you'd block the fist checkvalve top, so that it wouldn't leak half the water from there? Does it stop the water from activating the valve?
