Resurrection of a CFEI 100 KVA Induction Furnace
awemawson:
Thanks Phil. Loads more 'stuff' shifted from the Foundry building today (lucky that I re-roofed that Portakabin a while back!) but still loads more to move but I need to find homes for it :bugeye:
awemawson:
So hoo blooming ray the long expected 100 mm length of 1" BSP threaded stainless pipe arrived today. Supposedly from Southern Ireland but it was wrapped in the usual 'I've come from China' packaging. - I reasoned that it must have been packed well over the 72 hours the virus can survive for so it was 'probably' safe.
This allowed me at last to do a dry assembly trial fit as I need to arrange the 15 mm pressure control back feed to the tank via the gate valve at 35.5 mm off the base. Once that was proven possible I was able to slice off the remaining bit of vertical plastic pipe with some confidence that I can bond onto the stub and still be able to get the pipes assembled. In practice the 15 mm pipe has ended up about 5 mm too low, but I think that there is sufficient flexibility in the system to accommodate that.
The Christmas Tree of plumbing has been assembled on the bench with Loctite 542 and once that is fully cured I can trim the last bit of the plastic stub and solvent glue that on.
. . . slowly slowly . . catchee monkey :clap:
awemawson:
The Loctite 542 having cured I was able to re-assemble the pump plumbing in the chiller and make the solvent weld joint to the original plastic pipe. This itself needs to cure for 24 hours before I can fully tighten the various other joints and finally re-connect the motor and run a test.
I hope to heck that that seal works after all this faffing about :bugeye:
John Rudd:
Confidence, confidence.... :thumbup:. As Dennis said, ' it'll be alright on the night...'
Just dont forget....as I'm sure you won't....Dont run the pump dry!! Or bye bye seal... :doh:
Good luck..
awemawson:
John the seal is laced with washing up liquid at the moment and I will initially put just a bit of water in the tank and turn the pump by hand using it's cooling flange before any power is applied.
First thing is to slowly fill the tank and watch for static leaks, and to that end I've just resurrected a hose pipe point not too far away (O ring seals totally crunchy after a few years in direct sunlight), and I've reconnected the motors wires and bolted it's flange down.
So if I can persuade her tomorrow it'll be wife on the tap and me with hose in the tank 20 yards away yelling STOP :bugeye:
