Hydraulic Principles
 
 
 

Pressure is stress that is exerted uniformly (or the same way) in all directions.

 

Pressure is measured in units of force applied per unit of area.

 

Force exerted on a square inch of area of a confined liquid is transmitted at every angle to every square inch of area of the interior of the vessel. If one of the areas of the interior of the vessel is a second piston, the force would be transmitted to every square inch of its area as well.

 

In a schematic drawing (shown on the right) of a vessel which contains a liquid. Piston A is exerting a force of 2000 lbs. on the confined liquid. The effective area of Piston A is 1 Sq. In., so the pressure exerted on the liquid by Piston A is 2000 psi.

 

Hydraulic / Mechanical example:
If pump piston A is pushed down 12 inches, then cylinder piston B will rise 1 inch.

 

Pressure = 2,000 PSI

Piston A @ 1 sq. in. = 2,000 lbs.

Piston B @ 12 sq. in. = 24,000 lbs.

  Basic Hydraulics At Work  
  Hydraulics is based on a very simple fact of nature - you cannot compress a liquid. Now if you put that liquid into a sealed system and push on it at one end, that pressure is transmitted through the liquid (confined/sealed vessel) to the other end of the system. The pressure is not diminished.

  Basic Physics  
  Basic physics tells us that we can trade off force for distance in all mechanical systems. In a hydraulic system, we do this by changing the relative size of the pistons at each end of the system. Click on the link above for complete details.
