what is hydraulics, it's history and components?

Answer 1

Who do I look like, Henry Ford?

I think hydraulics involves taking fluids and using pressure to make them do something. I'm sorry, but I really don't know?

Answer 2

"Discovered" by Archimedes, a greek scientist who supposedly jumped in a bathtub and recognized the volume of water displaced by himself, Hydraulics is the use of fluids to do work. It's most basic components would be a fluid, a vessel, a motive force, and something to be moved. The crux of hydraulic power is that most fluids are incompressible, so if a volume of fluid is moved into one end of a vessel, i.e. a tube, the same volume of fluid on the other end of the tube will move the same distance at the same rate. Hydraulic system components would consist of a reservoir of a fluid, a source of pressure, be it a pump, gravity or otherwise, tubes, valves, and pistons, or hydraulic motors.

Answer 3

Hydraulics is a method of powering objects and can be used instead of electricity or pneumatics. Oil is compressed to great pressure (more than 16 Bar). Valves (switches) are then used to direct this high pressure oil down different paths. These paths eventually lead to actuators/rams which power forward and can move great weights such as a car etc. Some cars use hydraulic brakes, in this case oil is pressurized and when you press the brake a valve moves to allow air into the cylinder which moves the brake pad and slows the car.

Answer 4

Hydraulics is a science and engineering subject dealing with the mechanical properties of liquids. Hydraulics is part of the more general discipline of fluid power. The word "hydraulics" originates from the Greek word ὑδραυλικός (hydraulikos) which in turn orginates from ὕδραυλος meaning water organ which in turn comes from ὕδρω (water) and αὐλός (pipe). The earliest masters of this art were Hero of Alexandria and Ctesibius. The ancient engineers focused on sacral and novelty uses of hydraulics, rather than practical applications. Ancient Sinhalese used hydraulics in many applications, in the Ancient kingdoms of Anuradhapura, Polonnaruwa etc. The discovery of the principle of the valve tower, or valve pit, for regulating the escape of water is credited to Sinhalese ingenuity more than 2,000 years ago. By the first century A.D, several large-scale irrigation works had been completed. Macro- and micro-hydraulics to provide for domestic horticultural and agricultural needs, surface drainage and erosion control, ornamental and recreational water courses and retaining structures and also cooling systems were in place in Sigiriya, Sri Lanka.

One of the founders of modern hydraulics was Benedetto Castelli, a student of Galileo Galilei.

Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties. Hydraulic topics range through most science and engineering disciplines, and cover concepts such as pipe flow, dam design, fluid control circuitry, pumps, turbines, hydropower, computational fluid dynamics, flow measurement, river channel behavior and erosion.

Answer 5

The major components that make up a hydraulic system are the reservoir, pump, valve(s) and actuator(s) (motor, cylinder, etc.).


Reservoir, Pump, Vane Pumps, Piston Pumps
Oil is compressed to great pressure (more than 16 Bar). Valves (switches) are then used to direct this high pressure oil down different paths.
