一 液压技术的发展概况 当代许多最先进的技术装备总是同液压技术的发展紧密联系在一起的。无论在重型机器、矿冶机械、工程机械、机床、汽车拖拉机、农业机械、船舶等民用工业部门,或者雷达、军舰、飞机、火箭导弹以及宇宙航行等各个领域都广泛应用着液压技术。 自从英国人在1795年制造成功第一台水压机到现在,液压技术在工业上的应用已有180年的历史,不过,它与机械传动相比仍然显得相当年轻。到了十九世纪末期,德国和美国先后制成了液压龙门刨床和液压磨床,但是,由于没有成熟的液压元件,所以未能得到普
A hydraulic technology development profile Many of the most advanced contemporary technology and equipment are always closely linked with the development of hydraulic technology. The hydraulic technology is widely used in various fields such as heavy machinery, mining and metallurgy machinery, construction machinery, machine tools, automobile tractors, farm machinery, ships and other civilian industrial sectors, or in various fields such as radar, warships, aircraft, rockets and missiles. Hydraulic technology has been in industrial use for over 180 years since the British succeeded in building the first hydraulic press in 1795, but it still appears quite young compared to mechanical transmission. By the end of the nineteenth century, Germany and the United States made hydraulic planer and hydraulic grinder, but due to the lack of sophisticated hydraulic components,
