液压传动在目前科学技术日益迅速进展的时期,仍然是一种先进的传动形式。随着各工业部门机械化、自动化程度日益提高,液压传动仍然显示出其强大的生命力,同时,也对液压技术提出了更高的要求。液压元件及装置的标准化、微型化、集成化及单元化就是适应这种要求而产生的。液压集成回路的研制适应了大部分机械工业对自动化、微型化、标准化发展的要求,国外先进的液压元件生产国都在竞相研制、发展这类产品,以满足日益发展的数控机床、机床自动生产线、航空、船舶、军工等生产的需要,并且在机械工业各个领域上得到愈来愈广泛地使用。
Hydraulic transmission is still an advanced form of transmission in the current period of rapid progress in science and technology. With the increasing degree of mechanization and automation in various industrial sectors, hydraulic transmission still shows its strong vitality. At the same time, it also puts forward higher requirements for hydraulic technology. The standardization, miniaturization, integration and unitization of hydraulic components and devices have been adapted to this requirement. The development of hydraulic integrated circuits has met most of the requirements of the machinery industry for automation, miniaturization, and standardization. Foreign advanced hydraulic component producing countries are competing to develop and develop such products to meet the ever-growing automatic production lines of CNC machine tools and machine tools. The needs of aviation, shipping, military and other production, and increasingly widely used in various areas of the machinery industry.
