HYDRAULIC THEORY Introduction A hydraulic system is defined as a‚ ‘machinery unit which uses fluid as a pressure medium’. It has a number of advantages over an electrical system of a similar working capacity. Advantages: (1) The power to weight ratio is at least 14 times better than an equivalent electrical system. (2) Self-resetting overload protection. (3) Self-lubricating. (4) Infinitely variable speeds. (5) No static electricity. (6) Linear motion.
