摘要液压站是由液压泵、驱动用电动机、油箱、溢流阀等构成的液压源装置或包括控制阀在内的液压装置。其作用原理一般为电机提供压力源带动油泵工作,通过液压集成块、液压阀等对驱动装置(油缸或马达)进行方向、压力、流量的调节和控制,实现各种规定动作。液压站广泛应用于各种场合的液压动力传动,它可以进行高度集成和全自动控制,可以根据具体的空间做出相应的形状,因此对液压站的设计具有很大的实际意义。48805

本论文以液压设计手册为依托,对整个液压系统从控制原理到缸体执行进行了详细设计。首先确定了液压元件的执行方式和各个结构功能参数,然后针对这种液压站的功能、机构特征,初步确定液压站的系统原理图 ,接着对液压系统的各个元件进行详细的标准件选择,最后将整个系统中各个元件优化组合并绘制了液压泵站总体装配图。

Abstract Hydraulic power pack is a hydraulic power source device which is constituted with such as the electric motors for driving, fuel tanks, spillover valve ,on the other way it is a hydraulic device including application valve. The general principles of its working is the electric motors provide he pressure to driven the pump, by the hydraulic manifold blocks 、and hydraulic valves to regulation control the direction 、pressure 、and the follow rate of the drive set to achieve all kinds of regulation actions .Hydraulic station is widely used on various occasions in hydraulic power transmission, it can be highly integrated and fully automatic control, the space can be made in accordance with the specific corresponding shape. So the design of hydraulic power pack have great practical significance . 

In this thesis, I designed the whole hydraulic system from control principle to implement by cylinder body based on the manual of hydraulic design detail . First of all, set the modalities for the implementation of hydraulic components and the structure and function parameters, and then determine the system principle diagram directed towards the function and institutional characteristics of this hydraulic power pack tentatively. The next ,I choice the standardized parts and components of hydraulic system detail. Finally, I optional regrouping the various component of the whole system and driving the installation diameter of the hydraulic power pack.
