I also think that increasing flow is better than pressure. Now I have a question about regenerative circuit for the splitter. If my cylinder is 5x2x24" Do you think that the ratio between the bore and the rode side "permit" a regenerative circuit? My concern is that the differential area of...

Ok, so I have almost finish the hydraulic circuit. My first idea was to use 2 hydraulic cylinder , one working and another one "lazy" but activate when necessary with an sequence valve. The cylinders are mechanically connected at the push plate side. the port on the lazy cylinder are connected...

Also maybe some of you can help me. Do you know where I can buy a conveyor belt drive pulley? something like this: Or an alternative to drive a belt?

I study some specs on several large chainsaw too. In the following graphic I put 2 gas chainsaw, 3120hp husqvarna and ms 880 Shtil. The other chainsaw are popular hydraulic motor found on many processor and 1 motor specs from a harvester. I calculated with the max RPM and PSI from the...

Thanks polemidis for the advice. this motor have a faster RPM but maybe not enough torque. �.7 cu in Parker MGG2��3�-BA1A3 Hydraulic Motor | Parker | Brands | www.surpluscenter.com I will make some calculation later. For the hydraulic feed saw, what if you have a proportional hydraulic...

Hi thank you for your 2 cent, I appreciate! I have explain my project a little bite, mostly the type of wood, the quantity I need to process per year, budget, the kind of processor "inspire" me . Message # 28. But it's true I have not a plan of the design of the processor yet. I need to do...

The models that I "study" have indeed a gearboxes and regular gear pumps, most of the time between two and three. Example: If you look closely you will see it This one above have an angle gear box. But they always say on their manual to run the tractor pto at 520-540 rpm. My tractor...

I have mainly maple, ash and beech. I would like to process 200 face cord per year. My budget is 7000 Canadian dollar. I need to purchase almost everything. I want to have a log table infeed, something like this: Theses models are driving by the PTO of the tractor.

Maybe I didn't explain myself clearly. I want two pump but if one is enough I will go with juste one pump. Do you mean something like this to divide the flow? I simplify the circuit for the demonstration. there is just a pump,some divider valve and actuator: It's not exactly a variable flow...

I undestand. But is there a difference between a pto pump that is mounted directly on the PTO of the tractor and that run at lower rpm . and a normal pump that run at high speed with a gear box ? Does one is more energy effective? Example(the number is close to reality): 1=...

Hi, I intend to build a firewood processor. And I have a question... well I have many but one for now. My processor will be working with the pto of my 80 hp tractor. I will put 2 pto pumps on the same shaft. This kind of pump have a hole for the shaft that go through the pump. and I will...

Hi, I want to build a firewood processor, And I wonder if I can put two PTO pump on the same shaft to have like a tandem pump. I need to have two pump to run the hydraulic chainsaw, the splitter Ram, the log infeed, split wood conveyer... Also I think I will not use a 2 stage pump for the...
