Thread: Web Goblin cnc has begun
I will probably add some anti-freeze when winter arrives. It was baltic up here last year ( had about 150mm thick ice on top of my pond ) and my workshop is only heated when I'm in it. I have some good anti-freeze somewhere that doesnt attack copper or aluminium or nylon/plastic tubing.
Is CH water pump any good for coolant?
I assume coolant is filtrated and free from magnetic metal bits. There is no brushes in a motor so it should last ages I suppose.
Thou must say I pritty much used it every day (YES worked thru it. .Tough breed up here.!!! ) so the water was never left undisturbed for long periods, So if your not going to use it for weeks on end then I'd recommend you drain the system just in case we have another artic winter. . . . . . Oh and the water is the same original water I started with 3+ years ago with no nasty's or funny smells, the fact It's distilled water and it's a sealed dark container that no direct sun light can get to helps (No windows in my shop).
Not sure how good a central heating pump would be. You would be reducing its normal flow rate down alot but most of them have adjustable speeds so you could slow it down a bit.
Jazzcnc. I am using distilled water. Normal water just causes too many problems.
"No windows in your shop" Does it have bars where the door should be?:lol:
Seriously thou I do have a great big steel door with no windows. . . And even that doesn't stop the scum bags.
A few months ago my workshop was broken into but thank fully we caught one of them.! . . wont go into details but lets just say we got the stuff back and real justice was served. .
I hope they learned their lesson.
the problem with using water is that bacteria can grow in it quite well. Distilled water is a better option for long term. I have been to several factories in the past where they were too tight to buy distilled water or the correct coolant for their machines and eventually the bacteria hard grown into a type of algae or fungus and it blocks up the pipework. This usually meant an expensive repair for the customer.
We use distilled water for coolant on our Co2 Laser at work but we also add 1ltr of an anti bacteria agent to kill anything that might decide to grow in the coolant. This amounts to a 1% mix and the whoile system is drained and refilled with new coolant once a year.
A few years ago I miscalculated the amount of antifreeze required for the system and put in too much. Not quite sure what chemical reaction took place but the coolant mix started to turn to a gel. Right PITA is was to clean out. Now we go for about a 15% mix in winter time.
Sorry Jonathan. I thought your were talking about normal water.
