Hello everyone,
I recently started retrofitting my CNC Lathe to a more modern controller.
Since I am now already tearing into the wiring and programming anyways I tought I might as well upgrade the coolant system while I am at it.
While looking into DIY cooling solutions I stumbled across many people using sump pumps to circulate their coolant.
However, thes cheap ones typically only have a head of approx 30ish ft. which should only result in a max. coolant pressure of ~10psi.
Since there is no significant difference in price when you buy import quality, I was thinking one could use a deep well pump like this one instead: 370W 500W 750W Solar Water Pump DC 24V 48V 60V Submersible Well Pump With MPPT Built in Controller Stainless Steel Ship from ES|Pumps| - AliExpress
They are typically rated for 300+ ft. of head and have a peak flowrate of 8+gpm. They should thus be able to deliver plenty of coolant pressure. Some of them also have stainless meshes that keep potential chips out and are rated for use in sandy waters, so they should be able to handle any abrasive particles that are small enough to slip trough the meshes.
Pretty sure 100+ psi is overkill and might actually separate the loc-line if that kind of pressure really builds in the circuit, so I'd probably also need to hook up a pressure reducer of sorts somewhere in line. I'm also considering using a small-ish accumulator tank and a pressure switch as a possible solution.
Posting this because I'm wondering if anyone else has already tried this as I couldn't really find any references to it, tough that might be because deep well pumps are such a hotly discussed topic on the internet, or perhaps because this is a really bad idea
If you or anyone you know of has tried this, what were the results? Would you recommend going down this path?
Perhaps someone also sees something immediately obvious why this is a bad idea and can explain to me why nobody is doing this?
P.s. yes the lathe is in an enclosure, so aside from the finer coolant mist I should be able to easily deal with the increased messiness of using a "high pressure" coolant system.
Cheers
