What is Hydraulics?

Hydraulics is the use of liquid fluid power that can be used to do some mechanical work and it is widely used in various manufacturing plants.Steel, automobile, power plants use hydraulics because hydraulic actuation has several advantages over electrical actuation. The fluid is ideally incompressible and it works on the principles of fluid dynamics.

How can one select this as a Specialisation subject?

Hydraulics is a section under the subject called fluid dynamics, and it is a stream under Mechanical Engineering.

Career in Hydraulics Domain and Prospects

The career will be inclined with mechanical engineering and thereby in maintenance of hydraulic equipment or design and development of hydraulic systems.

Companies offering projects in this space.

Hydraulics is widely used in manufacturing and production industries, in automobiles, aircraft, medical, food industry, packaging industry etc.  So the range of companies applying hydraulics is huge and hence a vast array of career prospects is available.Majority of the manufacturing units always have projects in the field of hydraulics and the size of projects vary.

Basic Terminologies used in Hydraulics

Some of the basic terminologies used arePower packs, accumulators, pumps, pipelines, heat exchanger, oil filters, flow,flow rate, hoses, strainers, hydraulic valves, Direction control, flow control, check valve, relief valve, reducing valve, adapters, cylinders/actuators, volume, viscosity, valves, NAS value, filters, heat exchangers, etc.

New Technological Trends in Hydraulics & Lubrication Systems

  • High precision valves with faster response.
  • Oil with higher viscosity index, i.e., it sustains viscosity over a wide range of temperature.
  • Synthetic and Fire resistant oils.
  • Smart power packs to reduce energy consumption.

What are Automated Hydraulic and Lubrication System?

Electronically controlled systems are referred to as automated systems. These systems take feedback from the downstream section of Hydraulic and Lubrication Mechanism (through proximity sensors, Position transducers, Pressure transducers, Heat detectors, etc.) and when these feedbacks are provided to the master controller, based on the algorithm set in the program, it decides what action should be taken, thereby not requiring any human intervention.

How new age hydraulics is totally different from new age systems.

Actually, the new age hydraulics is in sync with the new age systems. The incorporation of electronics has created electro-hydraulic systems withArtificial Intelligence embedded into them, thereby making expert systems where they are capable of taking complex decisions by themselves in order to provide precise results with very high repeatability.

Industries Dependent upon hydraulic systems

The range of industries using Hydraulic systems is humongous. Any industry using automated and mechanised systems would definitely be using hydraulics in one form or the other. Hydraulics has almost unlimited application in the production of goods in nearly all sectors of the country. Several industries are dependent on the capabilities that hydraulics affords. It is primarily based on the techno-economic parameters and the feasibility of the application.

Use of Hydraulic in Aeronautics industry

Aeronautics industry depends heavily on electro-hydraulic systems, where the aircraft is controlled using electronically triggered high precision valves also referred to as servo valves. Besides the aircraft, the aeronautics manufacturing plant incorporates electronics and hydraulics to manufacture and assemble an aircraft.
