液压传动相对于机械传动来说是一门新技术.但从1650年巴斯卡提出静压传递原理，1795年英国的约瑟夫。布拉狱利用这一原理在英国制成世界上靠前台水压机.使液压技术开始进入工程优先城算起，已有二三百年历史了。到了20世纪30年代才较普遍地用于起重机、机床及工程机械，近代液压传动在工业上的真正推广使用只是20世纪中叶以后的事，至于它和微电子技术密切结合，得以在尽可能小的空间内传递出尽可能大的功率井加以稍确控制，更是近20年内才出现的新事物。

9299百瑞彩票Hydraulic transmission is a new technology compared with mechanical transmission, but the principle of static pressure transmission was proposed by baska in 1650 and Joseph in England in 1795. Burrow used this principle to make the world's first hydraulic press in Britain. It has been two or three hundred years since hydraulic technology began to enter the engineering field. In the 1930 s is widely used in crane, machine tools and engineering machinery, the really promote the use of modern hydraulic transmission in industry just after the middle of the 20th century, for it is combined with microelectronics technology closely, as much as possible to deliver within as little space as possible power well big slightly control truly, but also the new things of nearly 20 years to appear.
