国内液压气动密封件行业的主要生产厂家近300个,其中40余家骨干重点企业的产量和产值占到70%。近年来,随着主机的发展不断扩大,液压气动产品发展较快,其发展速度高于机械工业。1986~1993年间,液压件产量的年递增率为10.41%,气动元件为23.51%;液压件产值的年递增率为18.27%,气动元件为24.27%,高于同期机械工业产值年递增率10.45%的水平。1994年以来,由于宏观经济调整,行业发展受了些影响,使逐
There are nearly 300 major manufacturers in the domestic hydraulic and pneumatic seal industry, among which the output and output value of more than 40 key enterprises account for 70%. In recent years, with the continuous development of the host computer, the development of hydraulic and pneumatic products is faster, and its development speed is higher than that of the machinery industry. Between 1986 and 1993, the annual rate of increase in production of hydraulic parts was 10.41%, and the aerodynamic components were 23.51%; the annual increase rate of the production value of hydraulic parts was 18.27%, and the aerodynamic component was 24.27%, which was higher than the annual growth rate of the mechanical industrial production value of 10.45% over the same period. s level. Since 1994, due to macroeconomic adjustment, the development of the industry has been affected
