Simple Centrifuge Home build

[waytallwhitey]

I built a variation of fastcote's CF set up and could not be happier with it! I just didn't use a cook pot for my collection bowl and I gravity feed into the CF. I'm only home for part of the weekend and can still manage to spin ~ 150 gallons and not loose enough time at home for my Queen to complain.

If you're on the fence about a filtration system, I strongly urge you to consider a CF set up!

how do you keep the motor mounting face dry with out some kind of mechanical seal on the shaft

If you look at the pics, you'll see that Ben used a threaded nut to act as a barrier; I cut a piece of conduit and JB Welded it into place. It only has to stop a very little bit of wvo when the motor shuts down

Hi Guys, I was going to start a new thread, but decided to post here.
I now have a WVO Designs Raw Power Centrifuge. I'm very impressed with the quality of it & Leon is a really nice helpfull guy.
I got it all set up late a couple of nights ago. I am using gravity to feed the fuge.
I have the heater with the system that bolts to the side of the fuge. I have a problem with condensation in the fuge & in the "clean" hose to the tank. I had the fuge running at 29.3 which is pretty much half way on the dial. The heater was on 100 then 80 then 70 & finaly 50. The heater was so hot you could not touch it. Is that right? My buddies kept laughing & saying "stop fecking touching it then". I was convinced the oil was far to hot. I had the flow quite slow. When I saw the amount of water inside the fuge & in the hose I shut it all down.
I pumped the oil up into the dirty oil container, then ran it through the fuge without settleing. I thought if there was any water in the oil the fuge would take it out. Is that right?
What temp do you guys run the heater at?
What speed do you run the fuge?
Im not sure what gallons or litres per hr I was running as I only tried it out for about 30mins alltogether.
Any help on this would be a big help. O yea another thing, When I took the lid off the fuge the water from condensation was dripping off the lid. There was no crap in the bowl.

I heat ~ 50 gallons to 160*F and then shut off my heater. I can do the entire barrel in about 6 hours and not lose enough heat to bother about it. I get no condensation that I've noticed and I have done over a thousand gallons since starting to use a CF

wvo or wmo?

what was the air temp where you were running that batch of oil? Are you getting condensation because the air temp is so low? Just a thought. I dont remember having that problem with with condensation.

Have you ruled out very water saturated oil? If not try a hot pan test with the feed stock and see if what you are running is highly contaminate with water.

I never run WMO in the CF. However, I cant imagine it differing greatly from WVO though.

Are you seriously gonna put WMO through you DFA V3?

Yea thats a good point. It is cold here now. I guess there must be more water in the oil than I thought. I will try a pan test later. I am making a vapor trap at the moment. I have run 40ltrs through the fuge with the heat turned up a bit more & the clean hose fastened to a funnel so that the steam does not go into the cuby just as a test. I am now letting the 40ltrs settle to see if there is any water in it. I'm also making the system so that I can drain off a bit of oil before I run it into the fuge.
On the DFA website before they changed it, they said you could run WVO,WMO,Karasene & other stuff that I can't remember.
I have discovered that its best not to talk about WMO on most of this forum as people don't fully understand it & it causes bad feeling between forum buddies. I don't want to upset anybody on here as I really enjoy taliking to everybody.
