【導讀】液壓站又稱液壓泵站，是獨立的液壓裝置。它按逐級要求供油。并控制液壓油流的方向、壓力和流量，適用于主機與。用戶購后只要將液壓站與主機上的執(zhí)行機構(gòu)用油管相連，液壓機械即可實現(xiàn)各種規(guī)定的動作和工作循環(huán)。液壓站是由泵裝置、集成塊或閥組合、油箱、電氣盒組合而成。集成塊－－由液壓閥及通道體組裝而成。油的冷卻及過濾。向的變換、力量的大小及速度的快慢，推動各種液壓機械做功。機床廠的液壓車間生產(chǎn)，自產(chǎn)自用。獨立出來，成為液壓件專業(yè)生產(chǎn)廠。1968年中國液壓元件年產(chǎn)量已接近20萬件；1973年在機床、農(nóng)。100萬件，一個獨立的液壓件制造業(yè)已初步形成。開始研制生產(chǎn)機械密封和柔性石墨密封等制品。礎(chǔ)件滯后于主機的矛盾日益突出，并引起各有關(guān)部門的重視。隨著國家進一步開放，三資企業(yè)迅速發(fā)展，對提高行業(yè)水平和擴。目前，液壓、氣動和密封件產(chǎn)品總計約。這充分反映了產(chǎn)銷基本銜接。的國內(nèi)市場占有率約為30%。1998年國內(nèi)市場液壓件需求總量約600萬件，

　　

【正文】 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 外文資料翻譯 6 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。 aerodynamic pieces of the total demand of about 5 million, with sales more than 700 million yuan。 Seals total demand of about billion. total sales of about billion. the development trend of the future affect the development of the main factors (1) product development ability, and the level of technological development and speed can not pletely meet the advanced mainframe products, major equipment and technology imported equipment and maintenance support。 (2) the number of enterprises manufacturing technology, the level of equipment and management standards are paratively backward, coupled with a strong sense of quality, resulting in low levels of product performance, quality, Reliability poor services in a timely manner, lack of user satisfaction and trust of the brandname products。 (3) industry specialization of production low, scattered strength, low repeat serious, between regions and enterprises of convergence products, bli ndly pete with each other, driving down prices, the decline of enterprise returns, lack of funds, liquidity difficulties, product development and technological transformation is inadequate and seriously restricted the industry to improve the overall level of petition and the increase of strength。 (4) The internationalization of the domestic market and the increasing degree of foreign panies have entered the Chinese market and participate in petition with the domestic private and cooperative enterprises, individuals, foreignfunded enterprises, such as the rise of stateowned enterprises due to the growing impact. the development trend 外文資料翻譯 7 As the socialist market economy continues to deepen, hydraulic, pneumatic and sealing products in the market supply and demand and there is a greater change, long ago to a shortage of the seller39。s market has basically bee a structural surplus of the characteristics of the buyer39。s market place . Overall capacity, is already in oversupply situation, in particular the general low level of hydraulic, pneumatic and seals, the general oversupply。 and the host of urgent hightech highparameter, high 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.
