hyd problems

[Redfarmdogs]

Hi I have the deverter valve located at the end of the hose that comes from the pump this is where it is returned to the reservoir or can go to the control valve . thanks for your help

Do you have the hoses in ports A1 and B1, or A1, and A2? Can you show a pic of the work ports?

Tell me again , why a diverter valve?

A diverter valve or priority valve is not necessary on a log splitter. If you want to use a two lever valve, they make one just for something like a log lift.

Do you have the unused ports plugged?

Ports are A1 & A2 ports B1 & B2 are plugged. Was told by a hydraulic company owner that donated the pump & valve to me that a flow control valve was needed. Also after some calculations at princess auto said yes the valve was needed.16gpm valve, princess auto #8154593 Thank you for your help

Ok, here is the valve.

Now here is the question. Does someone know how many GPM's the pump is pumping, and if so, why reduce the flow. . There is no reason to limit the flow from a log splitter situation, unless the control valve is smaller than the pump flow, or you want to slow down the cyl speed. If the flow control valve is capable of 16 GPM's, then you have the option of dialing in the GPM's you desire. You could have reduced the engine rpm to achieve the same results, less GPM's.

I don't know of any log splitter that has a flow control in the circuit.

Do you know the GPM rating of the log splitter valve?

Your 24 HP engine can power a single stage hyd pump of 11.5 GPM at 3000 psi. If that pump is a 16 GPM pump, you do not have enough HP to power it.

If the engines tries to stall, that means that the fluid is being blocked or the force required is too great. If the pressure builds to the relief pressure, then the valve will relieve.


So, in my opinion, you do not need the flow control.

Try the hoses in A1, B1. A/B should be on the same spool for cyl to function.

A2 and B2 should be on the next spool over.

Hi JJ I believe that the gpm is 17.0 maybe as high as 20.5.. Consider the engine runs idle 1200 1750 operating speed,

 

[J_J]

Your engine 24 HP Briggs should be able to run at 3600 rpm.

Your engine will start stalling at 11.5 GPM, and 3000 psi.

Is your engine to pump a direct drive?

 

[Redfarmdogs]

don't have my manual at hand but i believe that was governed speed settings. Yes on the direct drive. Won't the flow control valve after setting take care of the stalling problem? It is the valve at princess auto. Dave

The excess flow out of the flow control valve, is it teed into the return hose from the log splitter valve before it goes through the filter, and then to reservoir?

 

[Redfarmdogs]

hosed into a return manifold????????????? By-passing the return filter. Good point It will be

 

[J_J]

I am not sure you understand, but the return hose from the log splitter valve and the excess flow hose should be teed together and fed to the return filter and then to reservoir.
