− | + | A '''screw pump''' can lift [[water]] from below onto the same [[Z-level]] as the pump. Its is two tiles by one tile in size, and it can be either manually operated by a [[dwarf]] with the [[pump operator]] job or by using [[gear assembly|gear assemblies]] connected to [[water wheel]]s and/or [[windmill]]s. The direction you want the water to travel must be chosen at the time of construction. | |

− | The | + | Building a screw pump requires an [[enormous corkscrew]], a stone, wood, or glass block, and a [[pipe]] section. The light green X must be next to the water source and the dark green X is where the water exits the pump. Having specified the direction of travel, you must ensure that the source side of the pump is placed adjacent to and above (in the [[z-axis]]) a liquid. The screw pump will draw the liquid up from below, and distribute it out of the other side of the pump. Screw pumps are [[construction]]s that can be removed to recover the building materials. |

If this is all it needed, these units could be stacked on top of each other, but it's missing one thing - dwarf access. There's no stairs/ramps, and no good place to put them either that wouldn't interfere with the adjacent levels' water containment. | ||
+ | #Solution for a freestanding tower - fire escape! Sure, you could consolidate the up and downstairs into a single up/down stair tile, but I like the zigzag and symmetrical arrangement this one presents. Just build these on top of each other, flipping horizontally each time, and bam. Minimal yet aesthetic multi-level water pumping. | ||

− | + | ==Yet another example - Automated system== | |
− | + | I use this system in conjunction with a river to power the water wheels. | |
− | |||
− | |||
− | |||
− | |||
− | |||
− | |||
− | + | I wanted to be able to pump water up several levels without wasting dwarves on "Pumping". So by using a system of water wheels and gears, and a bit of trial and error until I fixed my leaking problems, I came up with the following solution, where the "1st" and "2nd" levels simply alternate until I reach the desired height. | |

− | + | The red gear transmits power vertically, while the other ones give power to the pumps. Switching from up to left (or down to right, the orientation of the <b>L</b> doesn't matter) stops water leaking back down the vertical shaft. A single water wheel provides enough power for about 4 storeys. You will, of course, want to insert floodgates with levers at various locations. | |

− | + | A problem occurs when as the channel fills - as soon as it's deep enough for the wheels to spin the machine activates, sucking water out of the channel and making it too shallow for the wheels to spin, leading to a distinct 'stop-start' behaviour. It just takes time to even out - I suggest filling the channel before starting on the rest of the tower. | |

− | + | == Notes == | |
− | + | * The source of the pump must be directionally adjacent to "Open Space" that is directly above a filled pool of liquid. | |
− | + | * In order to build pumps in a "hanging" state, as in the stacked screw pump example, the dark tile of the screw pump must be able to connect to a nearby machine; either already existing or designated to be built. | |
− | The | + | * The rear pump tile does not block movement. The front of the pump does block movement. |
+ | * Dwarves must be able to access and stand on the rear tile of the pump in order to be able to operate the pump manually. | ||
+ | * Active mechanisms connected to the pump will automatically start the pump; to prevent this either restrict water flow using floodgates, or put in a [[gear assembly]] linked to a [[lever]] to disconnect [[power|motion]]. | ||
+ | * Pumps can also be used in conjunction with a [[water wheel]] or a [[windmill]] to become self-powered. | ||
+ | * Pumps can not push water up additional Z-levels. That is, if you direct the output of a screw pump into a 1-square space surrounded by walls, the water will not "overflow" the walls. | ||
+ | * Pumps appear to work by destroying water infront of them, and creating it behind them (unless there is already 7 units behind them), since they won't stop creating water until they have 7 units behind you can eaisly fill the world with water to the level of the pump if you have a loop between the input and the output, and also connect the output to the world. | ||

Both the pipe and corkscrew can be built by a [[carpenter]], (the corkscrew is listed as something like 'enormous wooden cor' if you are using the single-width screen, but hitting {{k|Tab}} to expand the screen should reveal the full text). | Both the pipe and corkscrew can be built by a [[carpenter]], (the corkscrew is listed as something like 'enormous wooden cor' if you are using the single-width screen, but hitting {{k|Tab}} to expand the screen should reveal the full text). | ||

− | + | I recommend that you connect a lever to one of your gears beforehand. The pump will start pumping as soon as it has power. | |
