I am stumped; hydraulic circuit create overflow situation
I am stumped; hydraulic circuit create overflow situation
(OP)
I collect and process WVO for use as a fuel in my sprinter van. During the filtration an effective way of cleaning the WVO is to heat it up and centrifuge it.
Previously this OC20 pressure driven centrifuge has worked for me. At that time my return was just hung over the collection bowl underneath the centrifuge. It would run like this no problem, but was a little messy because of some small splashing that would occur.
Then I sarted using electrical driven centrifuges and hard plumbed my return into the top of the water heater as shown in this diagram. Couple weeks back the electrically driven centrifuge died, so I tried to use the OC20 pressure driven centrifuge as my backup (never removed it). During steady state running the oil will back up in the funnel and overflow onto the ground. I lost 35 gallons the other night. I find this interesting and can't figure out why this is happening. Orignally flow 2 and flow 3 were both going into the collection bowl and it would work fine. Now its only Flow 2 that is going into the collection bowl and it backs up? Note that in the original scenario the port that Flow 3 now goes into was open to atmosphere, and might have been venting.

I have a new electrically driven centrifuge coming from WVO designs so I will be back and running soon. Just want an answer as to why .....

I will post a video with the new centrifuge soon just for others viewing pleasure. Having a electric motor driven centrifuge does wonders because it gets rid of the whole pressure thing. When I do the electric motor driven centrifuge there is a bypass from the T w/ pressure relief valve that provides a certain amount of flow to the centrifuge, the return for this setup goes to the plumbed return on the top of the water heater. The return for the centrifuge goes to the top heater port of the water heater so then the funnel at the top becomes the vent per say.
It works so good and stable that I am able to run it over night and have fresh ready to run oil in the morning. I am able to do 70 gallons a day if I have to.
