Hydraulic vs. electrically driven pumps?

RE: Hydraulic vs. electrically driven pumps?
For example, I see hydraulic driven pumps used a lot in mining applications.
RE: Hydraulic vs. electrically driven pumps?
1) Weight
2) Starting Time
3) Noise
4) Maintenance
RE: Hydraulic vs. electrically driven pumps?
One question I have is whether the electric motor would overheat in a mud drilling application. Anyone have any experience in this area?

I have some more info. I am relative newbie at design, and I am looking into designing a submersible pump that is electrically driven (an electric motor directly coupled to the submersible pump). ......."
With many manufacturers throughout the world having invested a small fortune in development of electric submersible pumps, why would you want to reinvent the wheel?
My opinion is you are wasting your time and unlikely to succeed. Where will you get the motor from, how will you cool it during operation, etc etc etc.
RE: Hydraulic vs. electrically driven pumps?
If an electric cable breaks down in the hole it trips a supply breaker. If a hydraulic hose fails it ejects high pressure oil into whatever hole you're drilling: probably not ideal the hole was a well for potable water.

The power to weight ratio of a hydraulic motor is far in excess of an electric one.
Your customer needs to be re-educated about the benefits of hydraulics over electrical actuators.
Direct him here and we will show him the error of his ways!

RE: Hydraulic vs. electrically driven pumps?
That's possibly true IF you have an available source of power for the hydraulic pump to drive the motor. If you have to drive the hydraulic pump with an electric motor then the power/weight ratio of the system is much worse than the all electric design. Of course if saving weight in a specific part of the system is advantageous then hydraulics might still be better.

You are of course correct, what nutter would install a complete hydraulic system just to run a small motor.
It really only applies to mobile equipment.

The electric motor will need a bottom hole "dump valve" arrangement or an electric motor several times more hp for shutdown times when discharge pipe is loaded to the top of hole.
Irrigation water well people seem to wanna sell electric motors 4 times required head needs.
A hydraulic motor will usually start and operate at excess of it's stated design limit loads.
