Hydraulic Plunger water movement.

true for some motors but those that ARE designed to be switchable probably have a far greater lifespan than those that dont.

Oh I realize that switchable motors are designed to be switched and what not. They just arent designed to last 10 years when switched back and forth every 5 seconds. As opposed to motors that are designed to run 10 years in one direction, continuously.

I can not wait to see this autocad picture.

If the motor lasted three years providing that kind of awesome flow I would have no problem replacing that often.

look above, i already posted a export picture from the quick drawing that i made, if you would like a little more detailed one then i could work on it some more, just whipped out something quick to get my idea across

again, the pic is 10 post up from this one. its just a quick idea getter' acrossr' pic

opppps.

I didn't scroll up. Duh!

 

[Yellotang]

Wow, that is awesome.

Is the augerbit in a partial tube to draw the water through?

Answering my own question here.

Think I understand now. Here is the question.

How big of a DC motor will be required? Boat trolling motor?
What will the auger be made of? Acrylic, stainless steel?

Wonder how one could make this?

 

[Simms142]

what on earth would you need 30,000+ GPH for thats just rediculous for just about anything besides a 20,000gal tank

He's not looking for a 30k gph jet out of a 1" pipe. Think tunze wave box type of flow with no supplementation.

 

[humboldt reefer]

The auger would be awesome. Acylic probably would'nt be the best material. If you were to make it from a more flexible plastic you could just chuck some round stock in a lathe drill it and use a moddified part off tool and cut it like you would turn a thread. Then just strech it out like a slinky stick a rod through it and glue it. Viola instant auger.

 

[zapata41]

see now like minds are thinking together

i have no idea what size motor, but the size would be determined by the torque required to sping the auger asm.

 

[BeanAnimal]

Why not use a hydraulic motor. The reversing action would be the result of a spool valve and the shock of each cycle would be absorbed by an accumualtor.

[zapata41]

no hydraulics because that introduces oil into the system and if you dont want the chance of oil leaking then you have to again come up with a method to seal the point where the hydraulic motor meats the water. that is the nice thing with my design is that there are NO seals and NO real failure points

well besides the motor

97 bucks at wallmart
With 34 lbs of thrust and a 2-blade power prop known for durability and performance, MotorGuide's Thurster T34 gives you all the power you need for a great day of fishing. With an all-metal mount, thick-walled, 28-inch aluminum shaft, five speeds forward and two reverse. Fits any small fishing boat.

Just gut this bad boy and make a "reef safe" housing for the motor tunze is looking overrated more and more every minute

 

[zapata41]

lol, i dont think the wife would aggree with ta 36" long shaft sticking out the top of the tank, would look neat though in the tank, chopping up fish like the magic bullet food chopper

but that might be the motor asm. for the auger

Tim

 

[humboldt reefer]

lol. yeah thats what I meant just use this motor for the auger. The only thing I'm wondering about is sealing the shaft and the bushings. I was thinking teflon at first but that may wear out too fast. What type of bearings and seals are used in the wet end of pumps? Never took one apart before...well other than powerheads.

 

[humboldt reefer]

Ouch!!!! $293.15 for 6"bulkhead http://www.plumbingstore.com/bulkhead.html

 

[zapata41]

i never said the bulkheads would be cheap, again i am sure these could be built on a cnc lathe. as for bearing on the wet end of pumps, it seems to be a rubber bushing, fairly hard, that supports a ceramic shaft, the impeller then rotates around the shaft using water as the lubrication medium. so they are not tight fit and probably wouldnt work scaled up to the size we need for this app. i think somewhere , when i was looking for bearings for my pcx 40 pump, i ran accross some plastic bearings, time to go looking for them.

Tim

 

[zapata41]

ok here are the bearings we need
plastic bearings

that was just a quick search that came up with those, plastic resin races with either glass balls or stainless balls, the glass ones would work great, also comes with platic resin cages

now were getting somewhere

Tim

 

[zapata41]

actually i found some other bearings, made by KMS, a 3/4" ID or 1" ID and can handle around 800rpm, i am sure they can go past that a little if needed, ok well i sent them an email for a price quote, now i have something to deisgn around.

now to find a motor

 

[laverda]

Instead of bulk heads why not cut slots in the back of your tank at each end then weld the hole assemble on to the back of your tank like this.

I thinks a simple hinged paddle would be more efficient. or a horizontal piston
