What is hydraulic? As a word, it is derived from the word hydor, which means water in Latin.
What does hydraulics do? As a subject, it examines the behavior (applied mechanics) of fluids.
When Was The Hydraulic System Invented? Since it transmits forces and movements more easily and efficiently than friction systems, hydraulics have been widely used in machinery manufacturing and industrial applications in the second half of the 20th century.
CONTINUITY in the Hydraulic System (Venturi Theorem)
The flow rate of the liquid flowing in a pipe with different cross sections is constant. Therefore, it is seen that the speed of the liquid increases in narrow sections and decreases in large sections.
The flowing fluid velocity and its cross sections.
Definition of Hydraulic System The structure formed by the elements operating a mechanism with pressurized fluid power transmission is called a hydraulic system.
The hydraulic pump in the hydraulic system absorbs the oil from the tank and directs it to the system with its effective pressure. If the System Pressure is higher than the designed value, the system is secured by returning from the Pressure Adjustment valve to the tank. The oil sent to the direction control valve by the hydraulic pump is directed to the user elements (Hydraulic cylinder, Hydraulic Motor, etc.) the moving user element operates the machine to which it is connected. The speed of the machine (mechanism) can be changed by adjusting the flow rate of the oil passing through the flow control valve. In order to ensure the back and forth movement of the user element, the flow and return paths of the oil are alternately changed by the directional control valve.
What are the Equipment Used in the Hydraulic System? 1- Hydraulic Tank (Tank) 2- Hydraulic Pump 3- User Elements (Hydraulic Cylinder - Hydraulic Engine etc.) 4- Hydraulic Valves 5- Hydraulic Accumulators 6- Hydraulic Pipe - Hydraulic Hose- Hydraulic Fittings 7- Hydraulic Sealing Elements 8- Hydraulic Filters 9- Hydraulic Cooler 10- Hydraulic Accessories, Hydraulic Indicators
Blaise Pascal Contribution in Hydraulic Systems
Blaise Pascal (June 19, 1623 - August 19, 1662) was a French inventor, mathematician, physicist, writer, and philosopher. He was a child prodigy trained by his father, a tax collector in Rouen. Pascal's early work was in the field of natural sciences and applied sciences. During this period, he made great contributions to the studies on fluids and generalized the work of Evangelista Torricelli and clarified the concepts of pressure and vacuum. At the same time, Pascal advocated the scientific method.
Despite his youth in 1642, he pioneered some work on calculators. After three years of effort and fifty prototypes, he was one of the first two inventors of the mechanical calculator. Over the next decade, the Pascal calculator built 20 more of these machines, later called Pascaline. Pascal was an important mathematician who helped create two main research topics. At the age of 16, he wrote a remarkable treatise on projective geometry, later matched Pierre de Fermat in probability theory and had a major influence on the development of modern economics and social sciences. Like Galileo and Torricelli, he refuted the followers of Aristotle in 1646, who defended the statement "The universe does not accept emptiness". The results of Pascal's work caused various debates before being accepted.
In 1646, he and his brother Jacqueline became identified with Catholic movements. His father died in 1651. Towards the end of 1654, he made impressive work in the field of philosophy and theology using his religious experience. The two best-known works on the conflict between a Jansen disciple and the Jesuits are Lettres provinciales and Pensées from that period. In the same year, he wrote an important scientific work on the arithmetic triangle. Between 1658 and 1659 he wrote on cycloids and its use in calculating the volume of solids.
Pascal's health deteriorated especially after he was 18 years old and he died 2 months after his 39th birthday.
