Trend of Hydraulic Technology

Date： 1970-01-01

Hydraulic technology is a key technology to modernize transmission and control, the world of the development of hydraulic industry have given great attention. Total sales of hydraulic components for the world's $ 35 billion. According to statistics, the major countries of the world Hydraulic Industrial sales accounted for 2% to 3.5% mechanical industrial production, while China accounts for only about 1%, which fully shows low utilization of hydraulic technology, efforts to expand its application areas, will have broad prospects for development.

Hydraulic and pneumatic technology has unique advantages, such as: hydraulic technology has the power to weight ratio, small size, high frequency response, pressure, flow controlled, and can be flexible transmit power, easy to achieve linear motion, etc; pneumatic drive with energy saving, non-polluting, low-cost, safe, reliable, simple structure, and easy and micro-electronics, electrical technology, automatic control system is formed. Therefore, hydraulic Pneumatic technology is widely used in various sectors of the national economy. But in recent years, hydraulic and pneumatic technology faces competition with the mechanical drive and electric drive, such as: CNC machine tools, small presses has electronically controlled servo system to replace or partially replace the hydraulic drive. The main reason is the hydraulic technology exists leakage, poor maintenance shortcomings. Therefore, we must strive to play the advantages of hydraulic and pneumatic technology to overcome the shortcomings, attention and electronic technology, expanding applications, while reducing energy consumption, improve efficiency and meet environmental needs, improve reliability, these are hydraulic and pneumatic technology to continue eternal goal, as well as hydraulic and pneumatic products whether participate in market competition to win the key.

As the hydraulic technology is widely applied to high-tech achievements, such as: automatic control technology, computer technology, microelectronic technology, reliability and new technology and new materials, traditional techniques with new development, but also the quality of the product, there is a certain level improve. Nevertheless, the 21st century Hydraulics impossible amazing technological breakthrough, should mainly rely on existing technology improved and expanded, expanding its application areas in order to meet future requirements. The main trends will focus on the following aspects. Reduce losses, full use of hydraulic technology in the energy converting mechanical energy into pressure energy and the inverse conversion process, there is always energy losses. To reduce energy loss, the following questions must be addressed: reducing internal pressure loss components and systems in order to reduce power loss; reduce or eliminate throttling losses the system to minimize the need for non-safety overflow traffic; using technology and static pressure new sealing materials reduce friction losses; improved hydraulic system performance, using load-sensing system, and the use of secondary regulation system accumulator circuits.
