【正文】 , 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 further improve the level of technology, technique and equipment to be greatly improved. In order to form a higher starting point, specialization, and run production has laid a good foundation. In 外文資料翻譯 4 recent years, many countries in the development of mon owners hip guidelines, under different ownership SME rapid rise showing great vitality. With the further opening up, threefunded enterprises rapid development of industry standards for improving and expanding exports play an important role. Today, China has and the United States, Japan, Germany and other countries famous manufacturers joint ventures or whollyowned by foreign manufacturers to establish a piston pump / motor, plaary reduction gears, steering gear, hydraulic control valve, hydraulic system, hydr ostatic transmission, hydraulic Casting. pneumatic control valve, cylinder, gas processing triple pieces, mechanical seals, rubber and seal products more than 50 production enterprises, attracting foreign investment over 200 million . dollars. the current situation Profiles After 40 years of efforts, China hydraulic, pneumatic and sealing industry has formed a relatively plete categories. a certain level of technical capacity and the industrial system. According to the 1995 Third National Industrial Census statistics, hydraulic, Pneumatic seals and industrial 370,000 annual sales ine of 100 million yuan in stateowned, villagerun, private and cooperative enterprises, individual, three capital enterprises with a total of more than 1,300, of which about 700 hydraulic, Pneumatic seals and the approximately 300 thousand. By 1996 with the international trade statistics, the total output value of China39。s growth stage for the rapid development stage. Which, hydraulic industry in the early 1950s from the machine tool industry production of fake Soviet Union grinder, broaching machine, copying lathe, and other hydraulic drive started, Hydraulic Components from the plant hydraulic machine shop, selfoccupied. After entering the 1960s, the application of hydraulic technology from the machine gradually extended to the agricultural machinery and mechanical engineering fields, attached to the original velocity of hydraulic shop some stand out as pieces of hydraulic professional production. To the late 1960s, early 1970s, with the development of mechanized production, especially in the second automobile factory in providing efficient, automated equipment, along with the Hydraulic Components manufacturing has experienced rapid development of the situation, a group of SME have bee professional hydraulic parts factory. 1968 China39。s a nd 70 for specialized production system 。 distribution of a full range of electrical control. Hydraulic Station principle : motor driven pump rotation, which pump oil absorption from the oil tank. to mechanical energy into hydraulic pressure to the station, hydraulic oil through Manifold (or valve binations) realized the direction, pressure, After adjusting flow pipe and external to the cylinder hydraulic
