Hydraulics - does this circuit work?

Click For Summary

Discussion Overview

The discussion revolves around the functionality of a double-acting hydraulic circuit designed by a participant. The inquiry includes concerns about the circuit's operation, the pump's performance, and the necessity of a load to prevent overheating of the motor. Participants explore various aspects of hydraulic systems and offer insights based on their understanding.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • The original poster (OP) seeks validation of their hydraulic circuit design and asks if the pump will function properly given the operational conditions.
  • Some participants express skepticism about the circuit's viability, with one humorously questioning the OP's qualifications.
  • Another participant believes the circuit should work, noting that hydraulic valves are typically designed for continuous use.
  • A later reply suggests ensuring that the bypass/regulator is adequately sized for the system.
  • Several posts introduce a light-hearted tone, with participants sharing jokes and personal anecdotes rather than focusing solely on the technical aspects.

Areas of Agreement / Disagreement

There is no clear consensus on the circuit's functionality; while some participants believe it should work, others express doubt or uncertainty. The discussion includes both supportive and skeptical viewpoints without resolution.

Contextual Notes

Participants do not delve into specific technical details or calculations that might clarify the circuit's operation, leaving some assumptions and conditions unaddressed.

Hello there,

I have designed a machine which requires a double-acting hydraulic cylinder. I need someone to let me know if this attached circuit works, if not why not, and whether there is a better way of doing it! The fluid will return to tank for about two thirds of the time the machine is switched on. Will my pump be happy? Do I need a reasonable load so that my motor does not turn into a massive 30kW electric heater? Help on this circuit would be much appreciated!

Thanks in advance

The symbols are unfamiliar to me, but... knowing you, it probably won't work. Cat did hire your for your looks, right? :-p
 
looks like a cartoon character :P

Yeah. I'm not sure what that big eyeball is looking at, but it certainly seems intent.
 
rofl yah, i immediately thought "whos eyeball is that"
 
Hey Brewnog, I don't see a problem with this circuit. Most hydraulic RV's are designed to be able to handle constant use (unlike gasseous ones) so having the pump go through the RV on every cycle is fine. If you have any concerns, I'm sure the folks selling the equipment can take a look for you, but from the little I know it's fine as is.

Oh god, that's like when some people throw a bucket of paint on the wall and start interpretting the 'art' of it and I am just sitting there crying because i don't know what there talking about.
 
I strongly suspect that Mr. Goest didn't note the time differential between the original post and my response to it. :biggrin:

HAPPY ANNIVERSARY, BREWSKI! :smile:
11th, that is. I just had to do it now so that nobody pre-empts me.

Ahhhh, so you were waiting the entire year before you all answered my question! :smile:

As you can see, art isn't my strong point. However, the circuit was all good, a real engineer told me so!

LOL, yep! My eyes never wandered onto that detail.

Looks like the OP kept well though, didn't get all stinky and rotton yet.

- And look! There's Brewnog, still under the same tree and rousing from his sleep! Perhaps he needs a shave and a cold beer, but it seems his mind is still sharp as ever.

Hey, I've only been here since February. It's not my fault that everyone else ignored you for 6 months before that. As for me, I just found the thread whilst wandering about aimlessly.

Slightly ironic really. I came here originally looking for some help. I didn't get any, but instead got sucked in and ended up being a helper-outer instead. Oh well.

I'm familiar with the concept. I came looking for help, didn't get any, ran into you instead, and ended up being a general pain-in-the-ass. I guess we all find our niche. :biggrin:

Well, if it's any consolation Brews...it should work fine. Just make sure your bypass/regulator is sized sufficiently.

How's that?
