摘要
液压系统中大部分使用具有连续流动性的液压油作为工作介质,通过液压泵将驱动泵的原动机的机械能转换成液体的压力能,然后经过封闭管路及控制阀(压力阀、流量阀、和方向阀),送至执行器(液压缸、液压马达或摆动液压马达)中,转换为机械能去驱动负载和实现工作机构的直线运动或回转运动通过设计好的油路驱动执行元件,使其完成一系列的动作。
本文设计主要对液压缸进行了设计,液压元件的选用,连接,液压泵站采用立式安装,对集成块的设计,以及各个部件的配合。为了使系统综合性能比较高,利用了集成块连接的方式,基于原理图复杂程度不高,采用三个集成块连接的形式。其中之一:保护器件,系统,还有部分保压的成分。第二:对速度的控制。第三:连通执行元件,起到控制执行元件动作和保持执行元件压力的作用。集成块设计完成后就是各件之间的配合装配。
关键词:液压缸;集成块;液压泵站;配合装配。
Abstract
Most of hydraulic systems use a continuous flow of hydraulic oil as the working media, will be driven by hydraulic pump prime mover of the mechanical energy into pressure energy of the liquid, and then after a closed piping and control valves (pressure valves, flow valves, and direction of the valve), sent to the actuator (hydraulic cylinders, hydraulic motors or hydraulic swing motor), the conversion of mechanical energy to drive the load and the work of agencies to achieve linear motion or rotary motion through the oil-driven actuator designed plete a series of actions.
This design mainly the design of hydraulic cylinders, ponents used to connect the hydraulic pump station with vertical installation, the manifold design, and co-ordination of the ponents. To make the system overall performance is relatively high, the use of the manifold ways to connect, based on plexity of the schematic is not high, with three manifold connections form. One: to protect the device, system, part of the ponents. The second: the speed control. Third: connected actuator, play action and maintain control of actuators actuators pressure. Manifold design plete coordination between the various pieces of the assembly.
