History

God created the first and most wonderful hydraulic system. It includes a double pump delivering a fluid flow rate of about 10 L/min at 0.16 bar maximum pressure. This pump feeds a piping network stretching more than 100,000 km. That’s nearly two and a half times around the Earth. It operates continuously for a very long time, mostly maintenance free. It is the human blood circulatory system. By the age of 50 years, the hearts of 10 men should have pumped a volume of blood equaling that of the Great Egyptian Pyramid (2,600,000 m^3) 

As for the hydraulic power systems developed by man, their history started practically 350 years ago. In 1647, Blaise Pascal published the fundamental law of hydrostatics: “Pressure in a fluid at rest is trans-mitted in all directions.” In 1738, Bernoulli published his book Hydro-dynamica , which included his kinetic-molecular theory of gases, the principle of jet propulsion, and the law of the conservation of energy.

By the middle of the nineteenth century, fluid power started playing an important role in both the industrial and civil fields. In England, for example, many cities had central industrial hydraulic distribution net-works, supplied by pumps driven by steam engines. Before the universal adoption of electricity, hydraulic power was a sizable competitor to other energy sources in London.

Hydraulic Doctor






Human body has The Best Sensors to  diagnoses hydraulic system failure.  its only time to use them at appropiriate time.  let us use them before going for machine diagnoses/analysis. Courtesy to D. Ramesh( My Guru and Teacher) who has originally conceptulised the thought of representing Human doctor. Thank you sir for your innovative thoughts and inspring us to do work hard.
