The History Of Hydraulics
People have been using liquids as a reliable source of energy for thousands of years. From the simple days of water turning mills to complex modern-day hydraulic power; our ability at the harnessing of fluid energy has improved rapidly. Hydraulics are ingenious designs use pressurized fluids to galvanize energy into pure power. But how did hydraulics ever come into fruition?
It was a real genius who realised the potential that confined fluids had. In 1648, Blaise Pascal concluded that fluids exerted an equal force in every direction. He claimed that one day, it would be possible to channel the power in the forces of the liquid to our advantage. He was correct. But he probably didn’t predict that hydraulics would one day become one of the most important inventions ever.
About 100 years after Pascal’s tests, Swiss mathematician called Daniel Bernoulli put the theory into practice. He used pressurised water in mills and pumps. Then in 1975, an Englishman called Joseph Bramah patented the first hydraulic press. The foundations of the industrial revolution were in place. It allowed the production of machines to cut or stamp things, as well as cranes and printing presses to name but a few.
Eventually, it was realised that simple H2O wasn’t the best liquid for the hydraulics, and that oil was a far better choice. A non-corrosive, dense oil would be able to perform to a greater degree and create more power, while not corroding the machine. The oil was found to be less susceptible to evaporation and held its temperature more readily than water too.
As time went on, through the industrial revolution all the way to the present day, the use of hydraulics became more and more common and widespread. This meant that innovations in the technology became exponentially faster. New materials were used in new internal designs creating greater forces and generating more power which allowed faster and more impressive production.
Hydraulics can give more than 10 times the power produced by an electric motor meaning it is more effective at lifting weighty objects and forcing things to move. Hydraulics can be controlled safely and precisely too and are closed off which protects workers. In the present day, hydraulic cylinders are used heavily in construction. Workers in mining, drilling, shipping and manufacturing all use tailored hydraulic cylinders to aid them in their jobs.
Hydraflow specialises in production and maintenance of hydraulic cylinders in addition to a range of hydraulic services you might need. Get in touch if you need any new application or need a hydraulics system at a manufacturers price.
