My Gold Pump is Melting

[MadArtillery]

I got lucky and found an Oil fissure pretty much right next to my base but there is a big problem. It vents at 320 degrees celcius and the Pump I sealed in there is melting despite being gold. Is there anything I can make my pump out of that won't melt in that furnace or is this Oil fissure a lost cause I should entomb and forget about? Alternatives also appreciated!

First and foremost, you need to realize there is a difference between overheat damage and melting.

Overheat means that your structure is taking damage from being too hot and will, eventually, break and need repairs.
Melting means your machine is...well, it turns into liquid.

If your machine is melting, the obvious solution is to just use something that has a higher melting point. However, considering that gold doesn't melt at 320C, you are probably just overheating it.

Liquid pumps have a base overheat temperature of 75C. Anything higher, they start taking damage. Gold adds 50C more to that. Steel, adds 200C. You'll notice that even with steel, your pump will still eventually take damage.

So.
You've essentially only got one option. Cooling loops.
You need to set up some liquid pipes, preferably radiant, snaking around the pump and surrounding area as best you can. I suggest using polluted water or any oil you've already pumped as your coolant.


Something to note with "loops": think of them like arrows. Items come out of green, and go towards white. They always do this, doesn't matter what the green or white is. This includes bridges. Once you have some fluid in the loop, all you have to do is put a bridge anywhere on the loop and it'll always go around.

Cooling the liquid itself is a bit trickier. If you're on rime, sigh in relief, because you can just use the asteroid itself. Else, you'll probably have to use machines.

Build a metal refinery, kiln (for refined carbon), and rock granulator (for lime) to make steel. Make sure you've got the power for it!
Alternatively, you could devise a method of cooling the oil before it reaches the pump, but that may take more effort than the above.

By the sounds of it I may very well have to do both unfortinatly. Without any ice biomes or even more than mildly cool biomes it's been a challange just to keep my base from heat death so I'll have to sort out some more power to actually cool the liquid and some way avoid the heat that generates as well. Hopefully with steel that will help until I can sort a cooling solution out.

It's a leaky fissure. Wall it off with insulated tile and move on.

Use oil fissures only after you get the steam turbine. Then you can cool the oil with water/steam before pumping. Do not cool it with anything that uses power or is otherwise expensive. It's a huge waste.

Pools of oil as well as oil produced by the oil well is a lot lower temperature and can usually be pumped with gold pumps.

Need to use Niobium at minimum to touch it directly with machinery. You can still put it to use but it'll take some creativity.

Spitballing off the top of my head I would have a reservoir underneath it to collect the oil. Some metal tiles along one wall that connects to a steam turbine room. Have tempshift plates suck the heat off the metal tiles into the steam and the turbine deletes the heat.

Next the bottom of the reservoir will be mechanized airlocks. Put a temp sensor in the oil connected to the doors that will open them and drop the oil when it is cool enough. The steam turbine will probably not get the oil cool enough for a gold pump. Make enough steel for one. Set the temp sensor to 130 and you should be ok.

That picture was just a quick throw together since your question made me realize I should work out a solution for my own future use. I let it run for a while now and the turbine eats a lot more heat than the oil can give. The oil never got high enough to fill an entire tile of height. So it can be much more compact.
