The development of hydraulic transmission technology

Hydraulic technology is an emerging technology developed by the principle of hydraulic pressure transmission. Throughout the history of the development of hydraulic transmission technology, it is divided into the following stages:

1. Origin stage

The origins of hydraulics can be traced back to ancient Greece in the third century BC. At that time, Archimedes discovered the principle of buoyancy and proposed the principle of the lever and the pulley, which laid the foundation for later hydraulic technology. Hydraulic devices were also used in ancient urban engineering, such as waterways, sluices, waterwheels, etc.

2.The initial application stage

 In 1795, the Englishman Joseph Breman registered the patent for the world's first hydraulic press. The commissioning of the hydraulic hammer mill by George Ludwig Rexroth in Spessart marked the beginning of the company's illustrious history.

3. Industrialization development stage

At the beginning of the 20th century, the French engineer André Pollitt invented the hydraulic cylinder for casting machine tools, which was an important breakthrough in hydraulic technology in the field of mechanical industry. From the 1920s to the 1930s, hydraulic technology was widely used in steel, machine tools, ships, automobiles and other industries, the most representative of which was the automobile manufacturing industry. The hydraulic system replaces the original transmission methods such as wire rope, lever, chain, rocker, etc., making the operation of the car more convenient, accurate and flexible.

4.Electro-hydraulic mixing stage

The combination of electrical technology and hydraulic technology has promoted the development of hydraulic technology. In the 50s of the 20th century, electro-hydraulic components were used in industrial automation control systems, which improved the control accuracy.

5 Intelligent development stage

In the 80s of the 20th century, hydraulic technology entered the stage of intelligent development. Electro-hydraulic technology has emerged one after another, and the control accuracy, performance and adaptability of the hydraulic system have been greatly improved. Since the 90s, the hydraulic technology represented by the hydraulic system of "intelligent flow" has greatly improved the intelligence of the system, making the hydraulic control technology more humanized and intelligent.

6.Green development stage

With the continuous improvement of environmental awareness, the "green" development of hydraulic system has become an important direction for the development of hydraulic technology. Reducing the energy consumption of the hydraulic system, reducing noise and vibration, reducing volume and weight, and improving reliability and life are all green directions for the development of hydraulic technology.

In general, with the continuous progress of science and technology, the application range of hydraulic technology will be more extensive, and the green development of hydraulic technology will become an important direction of hydraulic technology in the future.
