外文翻譯----液壓站及液壓元件發(fā)展概況-液壓系統(tǒng)-免費(fèi)閱讀
【正文】 從總體能力看，已處于供大于求的態(tài)勢，特別是一般低檔次液壓、氣動(dòng)和密封 件，普遍供過于求；而主機(jī)急需的技術(shù)含量高的高參數(shù)、高附加值的高檔產(chǎn)品，又不能滿足市場需要，只能依賴于進(jìn)口。 我國液壓、氣動(dòng)和密封工業(yè)雖取得了很大的進(jìn)步，但與主機(jī)發(fā)展需求，以及和世界先進(jìn)水平相比，還存在不少差距，主要 反映在產(chǎn)品品種、性能和可靠性等方面。按 1996 年國際同行業(yè)統(tǒng)計(jì)，我國液壓行業(yè)總產(chǎn)值 億元，占世界第 6 位；氣動(dòng)行業(yè)總產(chǎn)值 億元，占世界第10 位。從此進(jìn)入了快速發(fā)展期，先后引進(jìn)了 60 余項(xiàng)國外先進(jìn)技術(shù)，其中液壓 40 余項(xiàng)、氣動(dòng) 7 項(xiàng)，經(jīng)消化吸收和技術(shù)改造，現(xiàn)均已批量生產(chǎn)，并成為行業(yè)的主導(dǎo)產(chǎn)品。到了 60 年代末、 70 年代初，隨著生產(chǎn)機(jī)械化的發(fā)展，特別 7 是在為第二汽車制造廠等提供高效、自動(dòng)化設(shè)備的帶動(dòng)下，液壓元件制造業(yè)出現(xiàn)了迅速發(fā)展的局面，一批中小企業(yè)也成為液壓件專業(yè)制造廠。 閥組合－－板式閥裝在立板上，板后管連接，與集成塊功能相同。 and the host of urgent hightech highparameter, high 5 valueadded highend products, and they do not satisfy the market needs, only dependent on imports. China joins the WTO, its impact may be even greater. Therefore, the 15 during the growth of the output value of industry, must not depend on volume growth and the industry should address the structural problems of their own, increase the intensity of the adjustment of the industrial structure and product mix, is, we should rely on the improvement of quality, and promote technical upgrading of products to meet market demand and stimulating, seek greater development. 6 液壓站及 液壓元件發(fā)展概況 液壓站又稱液壓泵站，是獨(dú)立的液壓裝置。s advanced level, there are still many gaps, mainly reflected in the product variety, performance and reliability, and so on. Hydraulic products as an example, products abroad only onethird, life for half abroad. In order to meet key mainframe, and mainframe imports of major technology and equipment needs, every year a large number of hydraulic, pneumatic and sealing products imports. According to customs statistics and the analysis of data, in 1998 hydraulic, pneumatic and seals in the import about 200 million . dollars, Hydraulic which about billion dollars, aerodynamic nearly 030 million . dollars, sealed about 030 million . dollars. pared with a slight decline in 1997. By sums, currently imported products on the domestic market share of about 30%. 1998 pieces of the domestic market demand for hydraulic total of about six million, the total sales of nearly 40 billion。s reform and opening up policy guidelines, with the development of the machinery industry, based mainframe pieces behind the conflicts have bee increasingly prominent and attracted the attention of the relevant departments. To this end, the Ministry of the original one in 1982, formed the basis of mon pieces of Industry, will be scattered in the original machine tools, agricultural machinery, mechanical engineering industries centralized hydraulic, pneumatic and seals specialized factories, placing them under mon management infrastructure pieces Bureau, so that the industry in the planning, investment, technology and scientific research and development in areas such as infrastructure pieces Bureau of guidance and support. Since then entered a phase of rapid development, has introduced more than 60 items of advanced technology from abroad, including more than 40 items of hydraulic, pneumatic 7. After digestion and absorption and transformation, now have mass production, and industryleading products. In recent years, the industry increased the technological transformation efforts, in 1991, Local enterprises and the selffinancing total input of about 20 billion yuan, of which more than billion yuan Hydraulic. Through technological transformation and technology research, and a number of major enterprises to furth
