As early as 2500 BC, people began to use bellows. It is a form of practical application of compressed air. Later it was used in a wide range of mining, metallurgical and manufacturing industries. It was not until the mid-19th century that the application of compressed air formed a certain system, such as pneumatic tools, pneumatic picks, pipe delivery mail systems, steam locomotives and other auxiliary systems. Its use in real life also fully illustrates this point. By the mid-20th century, pneumatic technology was widely used in the fields of mechanization and automation, and its application in industries such as electronics, food, and medicine was constantly expanding. In recent years, with the large-scale development of robots and the development of factory automation, it has played a pivotal role.
The development and research of pneumatic technology in major industrial countries such as the United States, France, Japan, and Germany is very rapid. my country started late, starting in the early 1970s. Organize research and production of pneumatic technology.
