Have you ever wondered how a hydraulic press works? It’s not difficult to understand and can help you make better decisions about buying one. This blog post will cover the basics of hydraulics and show you how they work.

How Does A Hydraulic Press Work?

Hydraulic presses require hydraulic cylinders or “hydraulic rams”. High-pressure hydraulic oil is forced into the cylinder and the pressure is distributed evenly onto the piston of the cylinder. This pressure creates a force that extends the cylinder and exerts pressure on the pressed object. 

A hydraulic power unit delivers the high-pressure oil to the hydraulic cylinder. Hydraulic directional control valves control the cylinder to either extend or retract during production operation.

The forces and speed of the press can be finely controlled through proportional control valves and proportional pump controls.

This process is a direct application of Pascal’s Law. The law states that the pressure applied to any part of the enclosed liquid will be transmitted equally in all directions through the liquid.

You may have already seen the damaging effects of a hydraulic press on everyday household items in Youtube Videos. Still, a hydraulic press is even strong enough to flatten a solid natural diamond in an instant!

Why Use A Hydraulic Press?

There are several reasons why you might choose to use a hydraulic press over a mechanical one. 

  • A hydraulic press is cheaper and easier to maintain. 
  • A hydraulic press does not break down as easily. 
  • Press forces and speeds can be easily controlled using hydraulics. 
  • It is quieter than a mechanical press. 
  • The hydraulic system can convert a small amount of power into a large amount of force.
