Our
american hydraulic adapter(including hydraulic, the same below), pneumatic and seal industrial development process can be divided into three stages: the early 1950s to early 1960s infancy; 60 to 70 years of specialized production System growth stage; 80 to 90 years of rapid development stage. Among them, the hydraulic industry in the early 1950s imitated Soviet grinders, broaching, start copying lathes and other
flat seal metric hydraulic fittings transmission, hydraulic components plant by the machine hydraulic workshop production, production for own use from the machine tool industry production. Into the 1960s, the application of hydraulic technology from the machine gradually extended to agricultural machinery and construction machinery and other fields, originally attached to the OEM hydraulic workshop some independence, and become a professional manufacturer of hydraulic parts. By the late 60s, early 70s, with the development of production mechanization, particularly in the second car factory to provide efficient, driven automation equipment,
british hydraulic adapter components manufacturing has experienced rapid development of the situation, a group of SMEs It has become a professional manufacturer of hydraulic parts. 1968 Chinese hydraulic components production has nearly 200,000; 1973 in machine tools, agricultural machinery, engineering machinery and other industries, professional production of hydraulic parts factory has grown to more than 100, the annual output more than 1 million, a separate hydraulic parts Manufacturing has taken shape. In this case, hydraulic product development from the imitation of the Soviet Union for the introduction of technology and products to design a combination of product, pressure, and high pressure development, and the development of electro-hydraulic servo valves and systems, further expanding hydraulic applications. Hydraulic pneumatic industry started later than a few years, until 1967 to start building a professional factory pneumatic components, pneumatic components just as commodity production and sales. Containing rubber seals, mechanical seals and seal flexible graphite sealing industry, in the early 1950s from the production of ordinary O-rings, seals and other extruded rubber seals and asbestos sealing products start to the early 1960s, began to develop and produce mechanical seals and flexible graphite sealing products. 70s in the burning of the original part, a machine unit, the Ministry of Agricultural Machinery Systems, a group specializing in the production plants have been established and officially formed industry, laid the foundation for the development of the growth of the seal industry.
