Hydraulic transmission and pneumatic transmission are called fluid transmission, which is an emerging technology based on the principle of hydrostatic transmission proposed by Pascal in the 17th century. In 1795, Joseph Braman (1749-1814) in London used water as the working medium, it was applied to industry in the form of a hydraulic press, and the world's first hydraulic press was born. In 1905, the working medium of water was changed to oil, which was further improved.
After the First World War (1914-1918), the hydraulic transmission was widely used, especially after 1920, the development was more rapid. Hydraulic components began to enter the formal industrial production stage in about 20 years in the late 19th century and early 20th century. In 1925, F. Vikers invented the pressure-balanced vane pump, which laid the foundation for the gradual establishment of the modern hydraulic component industry or hydraulic transmission. The theoretical and practical research on energy wave transfer by GoConstantimsco in the early 20th century; his contribution to hydraulic transmission (hydraulic coupling, hydraulic torque converter, etc.) in 1910 made this Two areas have been developed.
During World War II (1941-1945), 30% of American machine tools used hydraulic transmission. It should be pointed out that the development of hydraulic transmission in Japan is nearly 20 years later than that in Europe and the United States. Around 1955, Japan rapidly developed hydraulic transmission, and in 1956 the "Hydraulic Industry Association" was established. In the past 20 to 30 years, Japan's hydraulic transmission has developed rapidly and has taken the lead in the world.
Hydraulic transmission has many outstanding advantages, so it is widely used, such as plastic processing machinery, pressure machinery, machine tools, etc. for general industry; construction machinery, construction machinery, agricultural machinery, automobiles, etc. in mobile machinery; Metallurgical machinery, lifting devices, roll adjustment devices, etc.; flood gates and dam devices for civil and hydraulic engineering, river bed lifting devices, bridge control mechanisms, etc.; power plant turbine speed control devices, nuclear power plants, etc.; deck hoisting machinery for ships (winches), bow doors, bulkhead valves, stern thrusters, etc.; giant antenna control devices for special technologies, measuring buoys, lifting and rotating stages, etc.; artillery control devices for military industry, ship anti-rolling devices, aircraft simulation, The retractable device and rudder control device of aircraft landing gear, etc.
Different hydraulic companies grew rapidly during that time.
