Why can't they use a natural Why? Because this morning I
saw on the news that an
elevator malfunctioned and
spilled hydraulic oil all over
the place. That's a hazard to
the environment. Why can't
they use another liquid?

Water is excellent as a hydraulic fluid because it doesn't compress. Its rarely used because it can cause corrosion. Other oils have the problem of compressing and so don't work. The other issue is cost. there are probably more environmentally friendly oils that cost more. at the end of the day, there should be no leakage. |

Why is hydraulic machinery so Thanks for the detail...I'm
amazed at how we all think a
bit the same...The question
before mine,under egineering,I
did not read before
hand...Word....Tom Science 4

The simple reason is that Hydraulics utilizes fluid as opposed to Pneumatics (air) although both are referred to as "fluid power" , the liquid normally oil used in hydraulics is simply uncompressible. SO THE FLUID is essentially stronger than STEEL when a pump pushes the oil to a device like a cylinder, imagine the fluid being a solid BAR of STEEL say 6 inches in diameter, it is literally like pushing a bar of steel. Heavy equipment say could normally operate at say 2500 PSI out of the pump, since the pump pressure is essetially regulated, it is simply a matter of selecting the desired force and sizing say the cylinder (for instance) appropriatey. Since: Force = Pressure (pump pressure) times Area (of the cylinder) The forces are absolutely staggering with a quarter of a million pounds force off a 10" cylinder at 2500 psi pump output. the chart below may not have been converted properly, but if you work the equations, you will see that the incompressibility of the fluid is the secret to limitless amounts of power. Usually safety is the only limiting concern with hydraulics as it is easy to die working close to anything with such reserve and speed. Cylinder bore Force at 2500 psi 2" 7,850 lbs 3" 17,663 lbs 4" 31,400 lbs 5" 49,063 lbs 6" 70,650 lbs 7" 96,163 lbs 8" 125,600 lbs 9" 158,963 lbs 10" 258,750lbs Pneumatics are faster usually, BUT NEVER as powerful due to the compressible nature of air. |
