Hydraulics

Power transmission with liquid means

Definition

The word Hydraulics originates from the ancient Greek words “hydro” and “aulos” and means “water” and “pipe”. Thus, hydraulics stands for the science of the flow behaviour of liquids. Hydraulics is all about pumping liquids to and fro in a closed circular flow and to perform mechanical work in this manner.

A bit History

During the 18th century, the Englishman Joseph Bramah invented the first hydraulic press powered by water pressure, which worked according to the hydrostatic law by Blaise Pascal. The so-called Bramah Press worked such that a piston was pressed and the resulting power was multiplied. Joseph Bramah pressed down the piston of a water-filled cylinder with a lever and with less effort. The resulting pressure on the water was then passed on to other cylinders and was thereby strengthened. At the end, an object with great power was compressed.

The advantages of hydraulics are that ...

Liquids can be stored under pressure
Pressurized liquids can be transported over long distances without major pressure loss
The pressure on liquids is maintained for a relatively long time and hardly changes
No force is lost when performing movements
Many movements can be realized with hydraulic cylinders without complex mechanics
A high positioning accuracy can be realized
It is possible to generate high forces and torques easily
Uniform movements are easy to implement

 

We want to explain these advantages and lots of other interesting information to you with the Hydraulics construction kit.
We also want to show you how hydraulic components work. We will explain the individual components step by step and show you how they work. The kit also contains numerous model examples that show how hydraulics can be used.
