here is a question for ya, if he has 40hp 40 ft lbs of torque and he is flowing 40GPM how much PRESSURE can the system develop before the motor boggs?

t

1500 psi or so. depends a little on the efficiency of the pump, and whether you count short momentary spikes, but sustained pressure will be about 1500 psi.

btw, didn't need the torque numbers for that, only the hp and gpm.

MR. Firewood asked drmiller100 this,

OK, we got a smart one here, lol
how many hydraulic HP = 1 gas horsepower? how many gas horsepower = 1 electric HP?
answer me that and I will see how good you are before I dismiss what you are saying as filth and lies!

and Drmiller100 had no answer to it


so heres the answer to that, look

i know my spliter is puting out way more psi and flow then drmiller100
thinks, and torque has everything to do with over all psi you will reach.

in the first picture is my engine V-4 wisconsin

second picture is wiscosin spec. sheet on a 37 hp engine
close as i could find to mine, 81 ft pounds of torque

third pic, is a close up of the chart

last pic the valve its a Gresen older inlet one inch, outlet 1.1/4
working ports 3/4

cyclinder 5 in. 2 in rod 3/4 ports

HP/ gpm

I not lookin to get in the middle of a pissin match,.. But arent the little 5.5 hp gas engines runnin around 10/13 gpm, Ive got one of thoes 4 cyl wisc's and they got pretty decent torque, I was thinkin the torque/hp was what produced the psi.... gpm is another thing,...I think you could probably pump 100 or more gpm at low psi. Its complicated for most people.....like me,,.E

changing teeth on the firewood processor in Toledo
you can flow 200 gallons per minute with a 5hp motor with no pressure

flow is determined by rpm, pressure under load is determined by torque, not horsepower,

Your saying I can have 100 HP and 40 ft lb of torque and still outwork a 40HP 100 ft. lb of torque motor? FILTH AND LIES!!!!!!!!!!!1111:laugh: :laugh:

here is another question I know you wont answer, I am going to run a 3 section pump on my new processor, the first section flows 30 gpm, and will run my main cylinder the other two sections will flow 9GPM at a regulated 800 PSI...according to your calculator how much HP am I going to need to split wood?

horsepower to me is like the way they measure wattage in the car audio industry.
at one time you would input a sine wave from 20hz to 20khz and measure the output voltage with a 4 ohm load and that was the way all was measured.
now they will test at 1k and the wattage will be way up but to a new guy with no idea wattage is what you looked for to decide your purchace.
I have a tiny gas engine that is used in radio controlled cars that puts out 2.5 hp.
so would that mean i could run a lawnmower with it????
I would think not cause the torque is almost nothing.
I think horsepower and torque go hand in hand but I dont know how to test stuff like this .
I think I would like to know how it is figured so if any of know pass it along.
I am not here to bash anyone as that will get us nowhere .
there are alot of things that will effect the splitter in the end

rpm
torque
horsepower

diesel engine in a semi has a redline of around 2000 rpm
my chevy truck about 5500rpm
my streetbike 13500 rpm

so i am sure splitter engine choices will have to be geared in some way??

how about a chevey 350 bolted to a 4 speed tranny into a pto pump??

your a dumb ass! horsepower gets you speed, TORQUE gets you pressure! you can refrence all the calculators you got a

i'd be interested in seeing an online calculator, or reputable article, discussing how 'torque' is needed to produce pressure.

and here i thought to produce pressure you needed restriction or resistance in the hydraulic circuit.

Mr Firewood

Torque is everything,..I chuckle every time I look at the sticker on my shop vac,..5 HP,..And the little moter under that piece of plastic is no bigger than my fist,..Air compressors have the big clames posted on them as well,..Iam not sayin they are guilty of false advertising But Ive got rubber bands that if you attached one to the turbine would prevent it from starting,..I want torque ,..Given that,.. Torque is how I measure power, in my shop,..I have a couple 5HP moters that weigh 75 / 100 lbs, they are 1160 rpm, But right there on the tag,. 5HP,. Weighing about 100 times as much as my 5hp shop vac moter,. sorry I could"nt help sharing this example,.. E, J,

Yes that is a hoist mounted on top of the splitter I beam. It is a truck bed crane with a hydraulic jack to raise and lower the boom. I have a 5000 lb warn winch to actually do the lifting.
See more Pictures attached.

1. More Torque is needed to OVER COME pressure, not produce it.

2. It takes little power to produce large pressure.

3. It take little power to produce large flow.

4. A pump designed to produce large pressure will require more speed to obtain more flow.

5. A pump designed for large flow will require more power to produce a larger pressure.

6. Combine the 2 and you get a two stage pump.

7. If someone need to explain mechanical advantage to you and how it relates to this then you need to grow a brain.

That is all.
