近年来,随着我国主机的发展和市场的扩大,作为基础件行业薄弱环节的液压和气动产品取得了长足的进步,其发展速度高于机械工业。1986年—1992年,液压行业产值平均增长率为16.07％,产量增长率为8.59％;气动行业产值平均增长29.15％,产量平均增长33.39％。技术进步产品发展更快,1992年已占液压件总产值的37.24％,占气动件总产值的19.65％。 1993年,我国液压气动行业主要生产厂有200余家,职工7万多
In recent years, with the development of the mainframe and the expansion of the market in China, hydraulic and pneumatic products, which are the weak links in the basic parts industry, have made great progress, and their development speed is higher than that of the machinery industry. From 1986 to 1992, the average growth rate of the hydraulic industry output value was 16.07%, and the output growth rate was 8.59%; the output value of the pneumatic industry increased by an average of 29.15%, and the output increased by an average of 33.39%. Technological progress The product development is faster. In 1992, it accounted for 37.24% of the total output value of hydraulic components and 19.6% of the total output value of pneumatic components. In 1993, there were more than 200 main production plants in the hydraulic and pneumatic industry in China with more than 70,000 employees.
