Development trend of hydraulic and pneumatic technology
Abstract: Hydraulic technology has been widely used in construction machinery, metallurgy, military industry, agricultural machinery, automobiles, textiles, ships, petroleum, aviation and machine tool industries. With the development of atomic energy, space technology and electronic technology, hydraulic technology has penetrated into a wider field and developed into a complete automation technology including transmission, control and detection.
Nowadays, the degree of adopting hydraulic transmission has become one of the important symbols to measure the industrial level of a country. Due to the development of industrial automation and FMS, pneumatic technology is required to research and develop system control technology and electromechanical liquid-gas integrated technology with the goal of improving system reliability and reducing total cost to adapt to electronic industry.
obviously, the miniaturization, energy saving and oil-free of pneumatic components are the current development characteristics. The adaptive components produced by combining with electronic technology, such as various proportional valves and electric servo valves, make the pneumatic system change from on-off control to feedback control. The wide popularization and application of computers provide a broader prospect for the development of pneumatic technology.
social demand is always the driving force to promote the development of technology. reducing energy consumption, improving efficiency, adapting to environmental protection needs, mechatronics and high reliability are the eternal goals of hydraulic and pneumatic technology, and also the key to whether hydraulic and pneumatic products can win in market competition.
it has been hundreds of years since the world's first hydraulic press was born in 1795, but it was after the middle of the 2th century that hydraulic and pneumatic drives were widely used in industry and developed greatly.
nowadays, the degree of adopting hydraulic transmission has become one of the important symbols to measure the industrial level of a country. 95% of construction machinery, 9% of CNC machining centers and more than 95% of automatic lines produced in developed countries all adopt hydraulic transmission.
