Yes, I saw the electric part. You just need to feed the beast
What is the company that you are working with for hydraulics? If I may know

i think i have the reliefs in all valve blocks..
the cylinder, in manual mode, will advance with push and hold button, it will stop automatic in the end of the stroke (even if you still push the button) by sensor detection, and it will stay stopped untill you push and hold the retract button..manual means manual
the purpose of the three gauges is simple: one for each valves block. One is for saw, one for all the stuff, and the other one is for splitter. This last one is messing around with me..one gauge for a valve block with two reliefs, that as two feeding pumps..how the **** i know the pressure of each pump?!?..

think i have to buy a tractor to feed it!!
The company is TECLENA, they are in Porto, Aveiro e Leiria..
Oh yes, I know it. I have Hidromarinha close to me, but they want to much money for everything.. Never worked with Teclena, but I think I will take a look at that. Thanks for answer me!

What kind of sensor stops the log splitter valve, and why is it even there, as the relief will protect the pump.
What is the sensor pressure limit?
I would set up relays to stop the end of travel of the cyl rod and another relay to auto return.
On the two pumps with two relief, are they set the same? If the relief are set to about 2900 psi, the relief will redirect the fluid to tank when a log causes the pressure to reach 2900 psi or when the cyl travel is at the end of stroke.
Recommend you disconnect the sensor and watch the hyd gauge at end of stroke to see what pressure the relief is set. If the log splitter gauge sows about 2800 to 2900 psi, you should be able to split about anything.
Which ever relief is set lower will relieve the pumps pressure.
The reliefs should be set to about 50 to 100 psi below the pumps max rating.
I have heard of people building their own cyl. but what kind of specs were used, and was any testing done?. If not, you have no idea of the cyl working pressure or any safety margin you might need.
Seems like I remember that cyl were tested to 1.5 times operating pressure.

This is what he said. { it will stay stopped until you push and hold the retract button..manual means manual }
So it is not automatic.
So it is not automatic.
this is in manual mode J.J...the machine was built to work semi-automatic..and it have sensors for that purpose..i don´t know what king of sensors they are, but they aren't pressure sensors..they are more like a "presence sensor" that send an electrical signal and it was seted up with a computer connected to the electrical automation..
well..the cylinder will be mounted today afternoon..and tomorrow it will be test day, if everything goes well ..

If the sensor is not a pressure sensor, what does the sensor do, other than alert you to the cyl position.
Do you not then press the return button to return the cyl, and if so, that is strictly manual.
Hope your test goes well.

jonix,
Good luck on your testing. I have not watched the video but in reading through the posts you should have two separate pressure setting for the splitter pumps to create the hi-lo system. The Lo pressure hi volume pump should be unloaded above a preset pressure. This would be done via a unloading or external piloted sequence valve and check valve. Once this preset pressure is reached the cylinder travel speed will be reduced to the low flow high pressure pump. This is the pump tha tshould have the relief set close to the systems rating or max motor HP which ever is less.
I believe you are describing a proximety sensor for cylinder stroke detection. These are immune to pressure spikes causing false reversals.
FYI: NFPA Industrial standards for cylinders is a 3 : 1 safety factor so a cylinder rated for 250 Bar should not explode with 750 Bar applied.
