摘  要

    液压泵作为液压系统的动力装置，越来越受到人们的关注，因为它的性能的好坏直接影响整个液压系统的工作可靠性。被广泛应用于冶金、矿山、锻压、注塑、船舶、重型等机械设备中。但在实际生产中还不能解决很好地流量脉动、刚性和柔性冲击等问题。平衡式径向柱塞泵的设计可以很好地解决流量脉动、刚性和柔性冲击等问题。通过设计使此泵在结构功能上能够适应现代化生产高要求的专用泥浆泵。
   泥浆泵（Mud Pump）也是一种宽泛的泵的一个通俗概念，不同的地域，习惯，最终涉及的泵型不会一样，本词条所阐述的泥浆泵是多数意义上的的一种泵型。事实上，污水泵，渣浆泵等一些非清水泵和泥浆泵在叫法上也有通用的时候。
本设计是根据给定设计参数完成专用泥浆泵泵结构设计，主要包括带轮、泵的结构设计。确定出几何参数，绘制并检查投影图，采对泵进行结构设计，绘制了装配图和部分零件图，并对轴进行了强度校核计算。
 
关键词：泥浆泵，专用泥浆泵，结构设计 The hydraulic pump as the power device of hydraulic system, more and more attention, because of its working reliability will directly influence the performance of the whole hydraulic system. Widely used in metallurgy, mining, forging, injection molding, shipbuilding, heavy machinery and other equipment. But in actual production is not properly resolve the flow pulsation, rigid and flexible impact problems. Better solve the problem of flow pulsation, rigid and flexible impact design balanced radial piston pump can. Through the design of the pump 2X-70 rotary vane vacuum pump can meet the high requirements of the modernized industry structure function.
Vacuum pump with mechanical, physical, chemical, physical and chemical method for pumping the container, in order to obtain and maintain a vacuum device. Vacuum pumps and other equipment (such as a vacuum container, vacuum valve, vacuum measuring instruments, the connection pipelines) consists of vacuum system, widely used in electronics, metallurgy, chemical industry, food, machinery, pharmaceuticals, aerospace and other departments.
The design is based on the  rotary vane vacuum pump structure design to complete a given design parameters, including the structure design of belt wheel, pump. To determine the geometric parameters, and check the projection mapping, mining design the structure of the pump, drawing the assembly drawing and parts drawing, and for the strength calculation.
