Self-sustaining pump-stack tutorial?
« on: April 01, 2012, 12:34:02 pm »

I'm trying to make a waterfall, and I've never used pump-stacks before.  I can't find any tutorials or step-by-step instructions on how to set one up, and I don't want to screw anything up while trying to learn.

Right now I've got a mining designation that looks something like this stretched up about 3-4 z-levels, with the channels alternating sides:

Code: [Select]
OOO
O+O
O+O
O+O
O_O
OOO

O = wall
+ = mined path
_ = channel

These channels are resting over top a 5x5x5 reservoir, that I have yet to fill.  The waterfall will empty back into the reservoir.  I've stared at those pump-stack diagrams until my eyes hurt, and I still can't figure them out.  If anyone could post some step-by-step instruction, I'd really appreciate it.

Also, a few extra questions:

1. Is 4 spaces per z-level long enough to fit each self-sustaining pump-stack?
2. After setting up a stack, what's the best way to start the perpetual motion thing?

i would just build water reactors and have my pump stack work separately.

While adding magma to anything will make it dwarfy, adding the word "magma" to your post does not necessarily make it funny.

This is my pocket Eternal&Movement McUrist Generator:

Level -1 Tank's water.

Legend: (W) wall, (.) floor, (o) gear assembly , (I) vertical axle, (_) horizontal axle, (XX) Pump. The coloured tree vertical (E) is a Water Wheel, (h) channel.

This little creature works very nice and generate a benefice of ~340 units of energy.

The trick with most pump stacks is how to power them. As you've observed it's easy to set up a series of screw pumps to move liquid up a number of z-levels - there's a couple of interesting bits to them though.

The wiki's design has the floorplan laid out as follows for the 'intermediate' pumps;

Code: [Select]
OOOOOO
O+_+_O
OOOOOO

Legend: O=wall, +=floor, _=channel

In alternating layers of course, design mirrored for successive levels. This leaves each pump in a 'Hanging' state in contact with the one beneath it - this allows it to transmit power. Of course this also makes it difficult to build and maintain - any pump built with no support will deconstruct (possibly with other consequences), so you need to build up from a solid base or provide support through adjacent gear assemblies or axles. Also, building destroyers can sabotage this design by dismantling any single pump.

If you want to go the extra mile and make it self-powering... your reservoir will need to drain such that it always has moving water of appropriate depth under the water wheels. Oh, and obviously you'll need waterwheels too. The catch is that even if you manage to construct an internal powering system it'll need to be started somehow, which will involve a separate power source (in which case you wouldn't need the self-powered bit so much), or dwarves on the pumps (which has its own problems, naturally, especially if there's no access to the system or if it is an accidental drowning trap).

It'd probably be safer easier to construct either a small Dwarven Water Reactor or, if you are blessed/cursed with an aquifer, to use that as a power supply through the infinite aquifer power trick detailed on the forum.

Code: [Select]
Dwarven Water Reactor

z=1

OOOOO
OW_WO
OW%WO
OW%WO
O+_+O
OOOOO

z=0

OOOOO
O777O
O7O7O
O7O7O
OO7OO
OOOOO


Infinite Aquifer Power trick

z=1 (Above aquifer)

OOOOO
O__WO
O__W*
O__WO
OO%OO
OO%OO
OO_OO
OOOOO

z=0 is channeled-out aquifer beneath channeled tiles

Activate by using pump once - make as big as necessary
 - pump access not shown but can be from anywhere

Legend: O = wall
        % = pump
        _ = channel
        + = floor
        7 = water
        * = mechanism / axle for power output

Whichever method you want to follow, good luck and remember that if it doesn't work you could modify it into a drowning trap with minimal effort - if it wasn't already, that is :)

Well, I did use it to deal with some tantrum-throwing, good-for-nothing children.

Thanks for the help everyone.

The bolded above? Not dwarfy. Embrace the screw-up-pump.
