This is the original prototype for the two part rotor being water tested. We ran this test for two weeks straight to test the seals.
|
This is a close up of the water test.
|
Because the lip on the two part rotor is wider then the original rotor we had to move the in-feed. This was quick and easy.
|
|
|
|
|
This is what the prototype looks like at a stand still.
|
This is the rotor opened for cleaning.
|
We are able to re-machine nearly all our early bowls into a two part rotor.
|
|
|
|
|
This is the first operation on the lid. The new lid provides four inches on overall height inside the rotor. We've also necked the inside lip down to three inches.
|
Testing the fit after the first operation.
|
This is the second operation on the two part rotor. The increase in volume is huge.
|
|

|
|
This is the dome lid installed on the base rotor. Still need to install the bolts and captive nuts.
|
This is the dome lid removed showing the seal arrangement. All seals are designed for 2100 psi. The rotor in motion only generates about 50 to 60 psi depending on the specific gravity of the liquid your running.
|
Rough bore the pie jaws on the mill for drilling and counter sinking the bolt pattern in the lid.
|
|
|
|
|
Boring the pie jaws to the final size.
|
Lid in pie jaw fixture ready to be drilled and countersunk.
|
Complete rotor with lid installed.

Bottom photo shows the stainless steel captive nuts.
|
Initial dry run.
|
Testing with motor oil. This is after adding one quart. By contrast the original rotor holds a little over a half a quart.
|
|
|
|
|
This is after two full quarts. Still more room to go.
|
Fully topped off, just over two quarts, 2.1 quarts. Right on my 2 liter target.
|
Original one piece rotor along side a couple proto type two part rotors. Note the size difference. The round shape creates a high pressure area near the back wall. This is similar to the cone effect found in cone bottom tanks. Improves separation.

|
This is the finished feed cone.
|
Bottom half of the two part rotor. Note the o-ring seals.
|
Feed cone installed.
|
|
|
|
|
Rotor lid installed. Hand feeding some oil into the feed cone. No splashing. Very awesome!
|
Rotor filled.
|
Redesigned lid has a center feed hole for the feed cone.
|
|
|
|
|
Completed lid. This tube goes into the feed cone.
|
This is the scum line from the two part rotor. You can see clearly the separation line from the dirty waste and the cleaner oil. This photo demonstrates the true value of the feed cone assembly. By forcing all the incoming oil to the back of the rotor only the lightest oil will make it to the front lip and out.
|
This photo shows the rotor portion of the last photo. This was about 80 gallons of waste motor oil.
