Our environment is full of hydraulic structures. Machines, cranes, hoists and other machines are equipped with hydraulic systems, even in our garages. To find out a little more about how these devices work, we've put together some basic information. Don't worry, this isn't an engineering thesis, just a generous overview.
Greek funds
Like many other sciences, hydraulics comes from the ancient Greeks. The word hydraulics itself - like all terms with the prefix hydro, hydra - is derived from the Greek word „hydor”, meaning water.
The concept of hydraulics in the scientific world the transmission and control of movements and forces by means of fluid you get.
The science of hydraulics is usually applied to other the physical behaviour of liquids also discusses.
One branch of hydraulics is hydrostatics, which investigates the phenomena of hydrostatic pressure generated by gravity within a fluid at rest, varying with altitude.
Another branch is hydrodynamics, which focuses its investigations on the the mechanics of flowing fluids stated.
In practice, hydraulics is often used to refer to the lifting machine itself or other a power transmission system used as part of a mechanical structure they understand. These can be in the braking system of a motor vehicle, a crane in its lifting mechanism, or even in a simple lift used during a wheel change.
Famous researchers in hydraulics
The primary laws of hydraulics in ancient times Archimedes put him to bed.
Continuing and developing his work Leonardo da Vinci who carried out many valuable laboratory experiments in the mid-15th century.
Renowned scholars of the XVI-XVII centuries - Stevin, Galileo and Pascal - also gained new knowledge about hydraulics and hydrostatics. Torricelli and a formula to determine the velocity of the fluid flowing out of the holes.
Internal friction of liquids Sir Isaac Newton has established regularities.
Functionality and practicality
Hydraulics is based on the principle that liquids are not compressible, so the power transmission can be achieved with relatively little energy loss.
As the in our article on lifters have already been touched upon, closed hydraulic systems are usually made up of a smaller cylinder (working cylinder) and a larger cylinder (working cylinder) connected by a pipe.
The system is always filled with liquid, which can be water, but it is now more common to fill systems with mineral or synthetic oil or some other special fluid.
A pump connected to a hydraulic system creates pressure in the fluid. The pressure is converted by various regulators and control units into a properly metered force and ultimately into transformed into movement and performance.
Benefits of
The hydraulic devices in lifting machines has many advantages:
- Power, torque and speed are simply, without grade can be controlled and regulated.
- Even with a relatively small size great powers are available, which are the can be adapted to the load.
- A overload protection is simple to do.
- A movement can be easily stopped, the lifted load can be held stationary.
Of course, the development of the last decades has not been without its impact on hydraulics.
Performance has increased significantly, thanks to increasingly sophisticated computer controls the movements have also become increasingly complex and complicated.
Our skilled staff have kept pace with these developments, so whether it's control systems or entire crane systems planning, on the authorisation of and implementation, we are at the disposal of existing and new customers.
