Resurrection of a CFEI 100 KVA Induction Furnace
awemawson:
Good to know that you are following along, frankly this is drawing on all my resources of enthusiasm and perseverance :(
A fair amount of Googling and Youtube watching tells me that this style of pump does indeed use reed valves, and pistons driven on an eccentric so I'm pretty sure that direction of rotation of the motor IS irrelevant.
It also told me that there is a 'telltale' to show the oil level which I eventually got to after much huffing and puffing (round the back down low very dark!). Now I can see 'something' in the tell tale window but am I seeing current oil level or an artefact from the level as was some time ago - what makes me suspicious is that it doesn't seem to be horizontal :scratch:
Laying concrete today so not more will be done I expect.

It's identical in construction to the Ingersoll-Rand that I'm rebuilding, in that case. I suppose it's a pretty common design. I've never played with a compressor before so it was all new to me when I took the crankcase cover off.

Absolutely following.
I've learned that 100kw induction furnaces are far more complex than I had ever envisaged...
You can't possibly give up until you have the next project on the go.

Years back when I had my Moog Hydropoint and needed large volumes of compressed air I had a Prestcold 3 cylinder inline cold room compressor - the integral 3 phase motor was too large for my converter to drive until I removed the cylinder head and took out the flat leaf valves for one cylinder - then it was fine ! That though was shaped more like a car engine with a crank shaft with three throws.

I must say it looks like a tide mark to me Andrew.
