what is the basics of hydraulic system?

Question

the basics of hydraulic systems,i.e.how energy is transfered from one place to another,how magnification of force is done?

Answer 1

Force is transferred using rams and fluid. A hydraulic system is a fluid filled system, From basic chemistry we know that fluids don't compress much therefore when using them to transfer force a minimum of the force is lost due to compression of the medium, usually a light weight oil.

To transfer the force a mechanical ram forces fluid to transfer from one cylinder to another cylinder via a high pressure connecting hose.

Multiplying force is a bit on a misnomer, basic physics states force must be conserved therefore force in must equal force out.

To "multiply" force you simply use two cylinders with a different cross sectional area. For instance if you compress one cylinder to transfer fluid into a cylinder with half the cross sectional area. Because force is conserved you will get twice the force spread across half the cross sectional area.

Answer 2

Force = Pressure X Area

So to create a force from a cyclinder, the fluid is put under pressure. This pressure acts on the ram. The cross section of the ram will determine the force. If the area is greater, then for the same pressure a higher force is produced.

The fluid is pressurized by a pump, and delivered to the cyclinder by hoses, capable of withstanding the required pressures.

Answer 3

hydraulic systems require the following essential things; a powerpack(pump)(this gives pressure to the fluid), piping(for transfer of fluid) and devices where hydaulic energy is converted into the desired motion(rams, hydro motors etc). fluids cannot be compressed and hence in the powerpack the pressure increases this pressurised fluid is passed through the piping to the "energy coverter" where the pressure reduces while motion is imparted.

Answer 4

Get a good Introduction to hydraulics book from library, with lots of colour full picture and study it.

In a nut shell, it uses various principles of fluids, to get end results.

Answer 5

the basic of hydraullic system is bournaully theorem

Answer 6

it's nothing but the pascal's law. i.e.pressure in must b equal to pressure out. pressure = force/area. so if the inlet's area is greater than the outer one pressure s more in outlet and so with less force v can lift more weight.
