I follow on the procedure however I have a trailer that has the pump submerged in the reservoir with a Honda engine on top. Kinda like a big ice cream machine with paddles inside it that run via hydraulics. I'm having to replace the pump. What would the adjustment procedure be for the new one?
Thanks for your question! Is this a submerged pressure compensating pump? Usually, the only way to set one of those is on a test bench, but you can usually order it preset to the desired pressure. Of course, if it is a fixed displacement pump, you need only set the relief valve, which should be external.
What if i hve a load sensing pump and no load sensing signal is connected to it that case load sensing screw should be fully tightened or fulley loosened? Or what will be its tightening and loosening affect on output pressure
Thank you for your question! The load sensing adjustment can be left at its factory setting if you like - as long as there is no sensing line attached, there is no need for adjustment. However, if you would like to disable it entirely to avoid "knob turner" issues, it can be fully tightened to ensure that only the compensator adjustment will affect the pressure. Just be sure that anyone who may be adjusting it is aware of the correct setting to adjust, perhaps a warning note on the pump.
@@JackWeeks thank-you so muchh sir! One more thing i wanna say is that it will be very helpful if you will make a vid on how to do null position setting for moog servo valves generally which are generally used in 6hi rolling mills😊
It certainly can! Always be aware of the design limits - download the specs from the manufacturer if you don't have them, and keep a nice cushion below the max rated pressure.
I would imagine 0 PSI would be the minimum. But it would depend upon the particular pump. For instance, some pumps have both minimum and maximum stroke limiters, so for that reason, must be idled using a tandem or open center directional valve that will unload the pump at idle,
Hi, we have a similar unit. Initially, there was a leak problem but still working. When we had the leak sealed, there is no pressure build up. So we tried doing what you had shown in this video, but still no pressure buildup. Hope you can help us.
JAYSON PENDON Hi, thanks for your comment! If there is no pressure building, that means there is no resistance to your flow. Fluid is returning to tank somewhere it shouldn't. The most likely culprit is a valve somewhere stuck open and providing a flow path to the reservoir. Hydraulic oil will always take the path of least resistance, so determine where the oil is going. A good tool for this is a thermal imaging camera, but you may need to install a flow meter, moving it to different lines until you find which one is dumping oil. Good luck in your troubleshooting!
Yes sir it's true someone turned the pressure above system relief valve and thanks once again
Best explanation on UA-cam!
Excellent videos!
Everyone watching these MUST WEAR EYE PROTECTION! ALWAYS!
PLEASE🙏
May I also request safety be first and foremost. Equipment should be secured before adjusting anything. Often hydraulics hold something very heavy up.
Superb sir . Very nice explanation.is it the same in the hydraulics pumps
Very nice. So what is best pressure set for roadblocker?
Don't know what a roadblocker is, but if it's hydraulic, the best pressure is the lowest one that will do the job.
Very nice!
Very interesting video!

thank my teacher
Good demo Thanks
Can too much pressure damage the pump?
It certainly can! Always be aware of the design limits - download the specs from the manufacturer if you don't have them, and keep a nice cushion below the max rated pressure.
What is the minimum pressure I can set with a pump?
I would imagine 0 PSI would be the minimum. But it would depend upon the particular pump. For instance, some pumps have both minimum and maximum stroke limiters, so for that reason, must be idled using a tandem or open center directional valve that will unload the pump at idle,
Simple and straşght forward
help me fix, or ajust my 2speed catapiller.. I wanna make it go faster..
Good morning
Nice

How bar set
If your gauge measures pressure in Bar rather than PSI, the conversion factor is 1 Bar = 14.7 PSI (at sea level).
