@@Rharaldseide I'm going to be making a centrifuge, I will be using an angle grinder for the electric motor should spin 7000 RPM I will do a RU-vid video once it's finished
@@Rharaldseide well keep it up man, i have dreamt of making an ROV for a long time. actually looking to make a centrifuge atm for WMO. hope to see some new vids from you with more cool stuff.
Yes if I used my time and effort to to do / make all this my self its real Diy 🤷🏼♂️ but i see its not possible to get all this done with a bedt screw driver and an weekend its my hobby / doomsday prepping skills to do ewhery thing my self.
Spannede rigg .bor fulltid i seilbåt og driver med dykking , hvor mye "forskning og arbeid" var byggeprosessen og hva blir prisen på en slik rigg? hva er max dybde ?
Testet elektronikk flasken til 400m men har kun 220m kabel på se videon min om bygge prosessen koster nå en del 1000 lapper… mye av delene er kjøpt på jmrobotics som forhandler bluerobotics deler og mye er laga sjøl..
The bowl must be ~10 inches in diameter. according to my calculations, a 10 inch inside diameter spinning at 6,000 RPM would develop 5,112 G's of centrifugal force. a 2-pole induction motor running on a 200 Hz variable frequency drive gets you there. If you subtract the slip loss of an induction rotor from the synchronous speed , the difference will likely land you right on ~5,000 G's. I like how you used the motor rotor that will drive it, as the spindle to turn the bowl. That helps insure a close enough dynamic balance, to allow continuous operation at high speed, with minimum vibration. NICE BUILD!! If I were to make any recommendation, it would be to make the top circle as small a diameter as possible, to give maximum radial depth from the inner rim to the top ring. That will allow better settlement of particulate matter, allowing for better filtration of finer particulate matter, or allowing a higher flow rate, with similar effectiveness. Depth X G force makes for better filtration, especially, for more viscous oils.
The rpm of a two pole induction motor without slip loss is 3000 rpm at 50 Hz (the normal line frequency in most of the world) so it only takes 100 Hz to reach 6000 rpm. When you calculated 200 Hz, you must have been thinking of a four pole motor. I too noticed how they put the motor rotor in the lathe, it was very smart.
Hi i just this winter got an erth fault in the compressor it was no nois on this pump the other on still runns so i changed it for a spare pump and changed the compressor in the on with erth fault.. not bad i think
Har du kjetting festet fra moringen/loddet å til land? Skal ordne utlegg for første gang til seilbåten min, å litt snodig usikker på hvordan jeg skal gjøre det.. for moringen/loddet vil vell flytte på seg gjennom vintern med kraftig fralandsvind?
*Extremely bright and heavy duty flashing.>>> **nub.best/00fg** Has 3 different settings which is nice if you don't need that bright of a light. Also comes with a nice padded lanyard to hang around your wrist. Highly recommend for anyone wanting an extremely nice flashlight.*
@@Rharaldseide thanks What cent. force you achieve Should 6000g do the job And the centrifuge holds how many gallons. I have to work with very low lpm.
I done a similar thing ten years ago. Same dimensions (228mm ext. diameter, 208 internal, 160mm for the "oil level") and about same speed, mine runs at 7000rpm, but I have made it from a 7075 ergal bar and balanced like a tool (g2.5at 10'500rpm). But is since 2012 that I don't have a Diesel. At now I'm wondering to convert it to clean the CNC coolant emulsion at my job.
Nice👌 mine is stil in use put some liters true it my primary car has 85k and my other has 40k on wvo ++ frinds and family😃 great project now it is fully automatic if you se my other project videos🤡
@@Rharaldseide yes you have done an awesome job! I decided in 2012 to quit with WVO and now I run my car on LPG. I used WVO for over 170'000 km in my old Fiat Punto TD with a DIY single tank kit. Simply a little 50W heater in the filter for cold weather, a 20plate heat exchanger between cooling and fuel systems, injectors with 15bar more opening pressure, and modified glow plugs (I modified the conical seat to allow the glowing part to protrude 2mm more in the prechamber). With these modifications I can run with oil even in winter, I tried it at -18°C with 95% oil in the tank, 4.2% gasoline, 0.5% winter additive and 0.3% acetone.
@@Rharaldseide yes, I achieved a great result with that work. At the time, I put the first few liter of oil in the tank precisely the 15/9/2003, the possibility of running diesels with vegetable oils was not known from the mass of people, here in Italy.
MrMadness yes the 7 kw motor i use is overkil but you use woth you have but a grinder motot running for days may die ... i can run 800-1000 liters a day but the heating that is a problem to i heat to 120 c before the centrifuge
Awesome man, but can you make a made poor man man's version from salvaged discarded on Street side which is very hard to get here now on Staten Island NY using a brace(hand drill), files, hamers, chisels, punches, hand saw for Wood, hacksaw which will filter out all oils of water and particulate matter?
@@danialleek1038 this is an old model not the same as newer models so i dont knew with is best and worse its probarly much the same all bigg produserrs now adays🤷🏼♂️
