upgrading wood splitter

[woodfar]

Hi, Woodfar here taking in all the advice and mulling it around in my head. You may understand a little better if ou know the popper term is relief valve opposed to release valve.and it is to protect from blowing the valve seals out and the packing from the cylinder. It is adjusted to around 2500 psi, ,depending on need. When the pressure reaches more than 2500 psi the relief, or bypass valve will open and let the extra fluid go back to the tank instead of blowing the cylinder apart. Do know a little about hydraulics and have that covered. Sorry if I misled anyone with the way I asked the question. Hope others get a better understanding of the relief valve. Thanks for all the responses.

We call them a pressure valve I would say put what ever hp you want. As long as your relief valve ( release- pressure - bypass- ) is set how you want it

Like I said I don't work with hydraulics that much and don't know very much about them, other then changing a hose now and then or repacking a cylinder. My question is what is the release valve for and why would they make it adjustable?

My experience is with hydraulic wrecker. Sometimes if the boom or wheel lift will not pick up the load it is designed to pick up the pressure can be adjusted so it can reach its potential. There are limits in the range of adjustment with a certain relief valve. There are higher psi relief valves depending on the application such as cylinder size, spool size in valve body and so forth. Without the relief valve, the pump will continue to build pressure until it blows apart or blows a weaker component such as a hose or oil filter. There are different types of pumps also, vain pumps and gear pumps. Gear pumps generally build more pressure.

If your wood splitter is made right it should have a hydraulic oil release valve. That being so it wouldn't matter how large the engine is. It will just put out so much pressure and the bypass valve will release. The only thing you will have to watch is how the engine and pump shafts match in height. As far as shaft size gos you can match couplings to fit. Also if you want a little more splitting power with the bigger engine I really don't think it would hurt to set the pressure up a little higher if the release valve is adjustable.

Lets get back to the question then a 12.5 hp engine in place of a 6 hp engine. As long as it has a hydraulic release valve the hp isn't going to matter that much.

Like reynoldston said... the Hp will make no difference..
If you had any way to cut the engine rpm and keep the pump rpm up, it may be quieter to work around...
The larger engine would have the torque to do that ... but it may not mount up as easily as a direct coupled system... :smile:KennyV

So to conclude this for the OP, he can put a 12.5HP B&S motor in his Wood Splitter as long as he can get it to fit ?

It shouldn't be too hard to mount the bigger engine. Lovejoy makes shaft couplings that will fit any size shaft. The last time I needed a coupling I bought it from tractor supply company.
