why does no one use a hydraulic accumulator to speed up the hydro log splitter ?

[texican65]

The only accumulators I've ever come across were the ones for a submarine hydraulic plant, 4500 psi, 3 pumps, 3 accumulators, they were huge...I'm trying to remember...maybe 100 gallons each...been awhile? controlling the rudder, control planes, and various shipboard equipment and gear. Applications like this is where I picture accumulators, probably not on a log splitter. Just not worth the trouble and $$$....unless you have time and $$$ to throw around. Cool idea though.

Second, the flywheel concept. My first thoughts where mounting the flywheel on the engine is the intent. My thoughts are the purpose would be to allow a smaller engine to pull a higher volume pump, at a lower pressure. That when the engine pump combo encountered a piece of wood that that required more hp to build the pressure needed, the heavy flywheel would provide the kinetic energy needed to provide a momentary boost of hyd pressure without stalling the engine. Might work, sometimes, other times, not so well. I believe even if it did work, the stress on the pump shaft would eventually lead to shaft breakage. Any thoughts on this?

The large flywheel doesn't work in a hydraulic spitter configuration, because the large flywheel is designed to release the stored energy quickly to over come short high load instances. You need the horse power to power threw knots.

Examples of where large flywheel with smaller engines works are the supersplit. Expels the energy in a fraction of a second compared to hydraulics where it may take several seconds to get there the knot. By then, the engine will be fighting the knot and trying to get the flywheel up to speed.

Another example is a buzz saw, or a wood chipper.

There's a vid of a kinetic energy wood splitter on YouTube somewhere that's really quite clever, a leveraged bouncing of a half ton counterweight on the end of a beam opposite the cutter?

It lifts the entire log round if the first bounce doesn't split it all the way through, the second does!

Arm powered. The splitting table's thick steel n static, with a six inch dia hole in the center for the blade to pass through undamaged.

Quite elaborate, probably weighing well over a ton, and taking up lots of room.

But brilliant in that his little daughter could split huge rounds with it, once the round's in place.

The most brilliant aspect being placing the operator ten plus feet away from the cutting action, and safely shielded from rounds goin pop.

Doesn't the Logboss use some type of accumulator ?

it could add any speed you could want from instant to just a little faster with a flow restrictor.

it wouldn't increase the impact force any really unless you left it wide open flow which would be just scary.

no videos i just got my 35 ton speeco splitter is seems to be fast enough for now. maybe later after i install a pressure gauge i might install one just for fun and a little speed. if you pump and splitter maxs out at 3000 psi you will still only had 3000 psi but would have more on demand flow so you could in theory add 2-5 gpm of pump while keep same hp engine with maybe a 50 percent duty cycle with no lost of stock power of speed

Change your weed dealer bro...
3000 PSI = 0.7031 Ton
So what is your point here???? beside the joke.!?!
I have a better solution
I remove the 6.5 HP engine from my splitter and I replace it with a 5 HP electric motor and use a portable power source in a 5 gallon bucket with 230 volts 3 phase alternative volts
Now that's a improvement. And 1 bucket is good for 2 1/2 cords.
Thanks for your attention.
