Dwarf fortress screw pump12/25/2022 =It turns out that water will be purified by screw pumps, but only if the receiving structure has never previously contained salt water. I must be an idiot though because after 3 days trying with the wiki and youtube open I still can't get a single level of pump stack to work either. cistern fills, holds water, not drinkable.Ĭistern is constructed from rock hauled up the mountain.ĭoes the cistern need to be made of blocks or bars? Basalt floor, basalt walls, basalt door into basalt floored pumping room. =desalination not as simple as portrayed The water inside the cistern will be desalinated. See Salt_water - you have to pump the salt water into a completely constructed cistern. Does that mean mud will contaminate the water and make it salty? I removed the pump, put in the floor, waited for all the water to evaporate and tried again - no dice. Initially I did the above but had not built a floor tile under the exit end of the pump, which did not work. Water source does not highlight, and designating it doesn't work. I stopped the pumping before the reservoir overfilled, then designated the level above as a zone. When I order the pump to be started, the reservoir gets filled. Pump pumping north to south from the lake, ramps put in for access while constructing, floor built under first tile of the pump. This is very misleading because while you can fill an area on the other side of it with some magma, the pump pretty much instantly catches on fire, and within a couple minutes will fall apart.- Krenn 06:40, (UTC)Ĭan someone add an idiot-proof explanation for how pumps desalinate water? I can't get it to work. The entry implies that you can pump magma with a pump containing some wooden parts. Leaving this here in case anyone else has a similar concern. Nevermind, pipe sections and corkscrews can be made of metal, just not rock.How is it possible to make a magma-safe pump (or rather, one which does not degrade into its component parts), since pipe sections and corkscrews can (apparently) only be made of wood? Rodya mirov Egodeus 17:45, 29 June 2011 (UTC) Magma-Safe Pump This is with magma and apparently also holds true for water. I hadn't kept that much of an eye on the pumps and the pumping tile had just evaporated. A pump will pump a tile to 0/7 when it pumps, but pumping will NOT occur if the tile is only 1/7 full. AutomataKittay 07:48, 26 June 2011 (UTC) Ok, I verified it. I haven't tried powered, but I'd imagine the behavior would be the same. My mistake about the always emptying out, it's either evaporation or just not pumping everything down to 1/7. It won't pump 1/7 out, but will completely empty 2/7 when ran on manual. I think you're right, did a quick test to verify. Perhaps the water was fluctuating like this between 1/7 and 2/7? - Thundercraft 21:38, 25 June 2011 (UTC) Also, I vaguely seem to recall a technical discussion on how water flows in DF that claimed the water level in a tile can, sometimes, fluctuate too fast to be updated on the screen. Perhaps there is confusion in this discussion due to terminology? I'm thinking, perhaps, pumps will not start pumping unless the source is at least 2/7 deep, but it will still drain the source to 0/7 if it had enough to start pumping? Just a thought. Non-empty tiles are mostly when surrounded by water and flowing in anyway from pressure. Egodeus 05:52, 23 June 2011 (UTC) I've done a lot of pumping, and it always drains water to 0/7 in the tile being pumped out when it can, assuming it's powered. I'm going out of town for the weekend so probably not going to happen before next tuesday. I'll try to do that once I get the chance. Egodeus 14:50, (UTC)Ĭould you record a movie of this and upload it to DFMA? I just tried this with water, and a screw pump would not move it from the source tile unless it was at least 2/7 deep. If no one corrects me I'm going to change that in a few days. In the notes section it is mentioned that pumps do not pump 1/7 amounts of liquids, but at least my pumps do in an unmodded version. Less than one, so to speak ) In any case, channel the water through a diagonal after the pump - 92.202.29.45 17:16, 22 April 2010 (UTC) I believe they move 7/7 per step. How much water do screw pumps move? Is it 1/7 of water per game frame? If you wanted to build a 1x1 waterfall that operated constantly without sourcing any new water, how many pump stacks would you need?Ī lot. 5 They only stack one way if you dig correctly.
