Thank you very much! This video was very helpful. My grandfather added hidraulics to the tractor but now I need to change the pump to an electric one . Now I don't have no one to ask how to make it. Thinga are now clearer. Thank you very much!!!😊
Your method of reducing pressure actually exponentially increases pressure. It decreases flow, but increases your pressure to the point it would be dangerously high.
Thank you for your concern. However, there are factors you are not taking into consideration. 1. As I explained in the video the pressure was set at 800 lbs. The pump pressure control will release pressure if it gets greater that 800 lbs. 2. The pressure on the spool valve side of the orafice will see a delay (a differential) in pressure release. Thus providing a momentary increase but will contsantly bleed through the orafice. 3. The pressure on the tank side of the orafice will immediately drop because of the larger hose size. 4. The defuser in the tank will release the pressure into the tank in a dispersed, harmless pattern. 5. The tank has a breather allowing any pressure to release quickly. 6. The components in the hydraulic system are rated at 3500 pounds or more - the pump has a maximum pressure production of 2500 lbs. Conclusion: Even if by some odd occurence the pressure got stuck at double the set 800 lbs the system can easily handle it. If I was operating at higher pressure I would have done differently but 800 lbs (even 1600lbs ) is hardly explosive.
you are so right plus heating the oil up, dont need nothing on return, open line. it open flow an the relief valve controls presser it not strait though
your videos are amazing at how you explaine everything! do you think that hydralic pistons are much better than linear actuators. I am in the planning phase of building a loader for my Sun Star Simplicity - i am very comfortable with electrical but not comfortable with hydralic systems
Yes, hydraulics are definitely superior. For some cost makes hydraulics out of the question. The medical / furniture grade actuators provide an option that costs much less. There are drawbacks with the DC actuators (not as powerful, not as weather resistant, designing loader with limits that coinside with the stop switches). Consider things like - does my tractor have a hydraulic pump already? - Some high end garden tractors have hydraulic mower decks, others are accessory ready with hydraulics. Will I have to add a hydraulic pump? Will I install a mechanical pump or a DC motor driven pump? I hope this helps, If I can help further just ask. Thanks, Ed
Hello you say u usehd a tool battery with your 24 volt system. I have 4of the 6 amp h. DW's 20 volts all new with maybe 10 charges on them. There workink load os 18.volts i think. Ive used it with 12 volt spot light cut car cigarette plug off put flat blades on end plug in battery wirks great. Wonder if they the dw battery would work with one battery for one actuator 12 volt. Or think it would let the magic smoke out. Thanks , should run bit faster im thinking if it don't fry it. 🥓 🍳. Lol.
i have a double acting pump and a double acting cylinder for my liftgate, i rewired the double acting pump to only kick on when going up and capped off the unused port on my cylinder but i keep on losing pressure causing the liftgate to go down slowly. Do i need to do a similar setup to make this work or should i replace the pump for a single acting? And if i do replace the pump will i still need a similar setup to make the cylinder work as i need it to?
I am not sure if I understand. Are you using the liftgate and cylinder on a new application such as a loader? Why did you alter a double acting pump and cylinder to imitate a single acting system? Double acting hydraulics are almost always better than single acting. The benefit of using single acting is almost always because it cost less. In my video I use a lesser pump (single acting) and upgrade it to imitate a double acting. I need more information in order to understand what you are trying to accomplish. Right now I would suggest that you restore your lifgate to double acting. If you are taking the liftgate pump and cylinder and repurposing them on a loader I would definitely want them to be double acting. I hope this helps.

I have learned enough to proceed with the double action cylinder press using an existing single action pump. Your video was very well done. Thanks!
Glad it helped

When I refer to pounds I mean pounds per square inch or psi.

I have powered actuators with 48 volt batteries. Your 20 volt batteries will work great.
