内容摘要:液压传动的基本原理是机械能与液压能的相互转换，液压千斤顶是典型的利用液压传动的设备，液压千斤顶具有结构紧凑、体积小、重量轻、携带方便、性能可靠等优点，被广泛应用于流动性起重作业，是维修汽车、拖拉机等理想工具。其结构轻巧坚固、灵活可靠，一人即可携带和操作，千斤顶是用刚性顶举件作为工作装置，通过顶部托座或底部托爪在小行程内顶升重物的轻小起重设备。
关 键 词: 液压传动 工作原理 故障 维护
Abstract:Hydraulic drive is to liquid pressure can for work of drive way ，its work principle is machinery can and hydraulic can of mutual conversion, hydraulic jack is typical of using hydraulic drive of device, hydraulic jack has structure compact, and volume small, and weight light, and carry easy, and performance reliable, advantages, is widely application Yu liquidity lifting job, is maintenance car, and tractor, ideal tools. Its light structure strong and flexible and reliable, one person to carry and operate, Jack is made of rigid top-lift as a work device, through the bracket at the top or bottom bracket feet lifting heavy weights in the small tour of small light lifting equipment.
Key words: Hydraulic drive operating principle broken down maintain
