Hello, I’ve got A10V pump with power control (DFLR). When I tried to adjust it, nothing changed. How does it work? As at full load a motor trips on overcurrent

@smca7271 Ай бұрын

Great explanation, I see the control valve has changed from tandem (1yr ago) to float.I have tandem but have bought a counterbalance valve to install (loader always drops before it goes up,not good). Will it work? and why....these seem to be a bit of a tricky beast.

Favorite video for quick reference. Thank you.

When You just let the parts fall uncontrolled after opening the valve You do not know the way they were inside and the mistake can be made while assembling it back :(

I consider this video provides the basic information but no show as to have to connect the flow meter to the existing hydraulic system.

if a swing of a crane rotates with the required speed in one direction and does not do fot the onother direction .. when we measure the pressure in the dcv it reads 50 bar in on direction and 40 bar in the other one ..so what may cause this pressure drop ??

The dude maybe knows what he is talking about, but in the era of multimedia, on YT actually just talking about how should it sound or how should it look like is so weak... And the dude just can't wait to go have a leak (or maybe too much coffee in the morning) my eyes hurt from following him on the screen... Or maybe his trousers are burning - there's some kind of smoke behind... Anyway - the best he could do was taking the filter to his hand from the table and putting it back even without explaining what should we look for in this image... National experts... Pfff...

Hey ,I love your teaching,your WhatsApp line please.For cansouting purpose

Great presentation, one question please. Once the pressure reaches 500 PSI and the pressure relief valve activates does the line pressure indicated on the gauge become zero PSI. I assume an closed relief valve will not hinder free flow? Maybe zero for a brief sec when over 500 PSI is reached?

@JackWeeks Жыл бұрын

Thank you for your kind comment and question. No, pressure does not return to 0 PSI once the relief valve opens, even for an instant. The resistance must continue to be overcome after the relief valve opens. Think of it as you holding a spring between your thumb and forefinger. When you compress the spring, you must continue to apply that force after it compresses, otherwise, it will stretch back out. The spring in the relief valve is the same way. In fact, if you install a second relief valve in the tank line of the first one, it will take the sum of the two spring settings to open them and keep them open. Many systems have this exact arrangement to remotely set a relief valve in an unsafe or inconvenient location. Hope this helps!

100 psi is not a completely correct value.

Am I mistake or would having a slightly larger hose to the piston side be required to maximize the efficiency of a regen circuit?

@JackWeeks Жыл бұрын

Not necessarily. It would depend on the total amount of flow delivered to the piston side. If the hose was already at its flow limit without regeneration, then yes, it is possible that the regenerated flow from the rod side could make the flow exceed the rated amount.

how many ohms the solenoid resistance

@JackWeeks Жыл бұрын

It varies to some degree with the coil and how it is wound. 20-50Ω is pretty common for 24VDC coils.

Recently purchased 2008 cat287C MTL. At anything less than full throttle it will start to move forward then gradually slow. With full throttle it will move out but if you start uphill it will slow down. I have not performed pressure check. Did dissect the filter after replacing and it had no metal filings or other debris inside. Any suggestions?

Great video! Does the ratio of the cylinder need to be 2:1? I have a 4” bore 1.75” rod cylinder for a log splitter that I wanted to add a regenerative circuit to but read that it should be a 2:1 ratio for the circuit to work, is this the case?

@JackWeeks 2 жыл бұрын

Thank you for your comment and question! No, the ratio need not necessarily be 2:1. Naturally, the greater the difference in surface area, the more pronounced the effect will be, but regenerative flow works with any cylinder (except a double rod cylinder with both rods the same size).

Thank you for the kind comment! No, I only have training for troubleshooting them - repair is not really recommended in the field because of the cleanliness requirements. Most places aren't set up for it.
