第三讲液压元件的结构原理液压元件的结构是用来实现各元件本身的作用而设计和逐渐完善起来的。任何一种新的结构形式的出现,都要经过实际运行或试验证实是否合乎要求,才能够被人们承认和利用。在液压系统中,油泵、油马达和油缸,是两大重要组成元件。前者是把原动机的机械能转变为液体压力能的装置,属于动力元件;而油马达和油缸,则是把液压能转变为作旋转运动或往复运动的机械能的执行元件。液压系统中所使用的
The third part of the structural principle of hydraulic components Hydraulic components of the structure is used to achieve the role of each component design and gradually improve. Any appearance of a new type of structure needs to be recognized and used by people after it has been verified by actual operation or test. In hydraulic systems, oil pumps, oil motors and cylinders are two major components. The former is a device that converts the mechanical energy of the prime mover into liquid pressure energy and belongs to the power element. The oil motor and the oil cylinder are the actuators that transform the hydraulic energy into the mechanical energy for rotating or reciprocating motion. Used in hydraulic systems
