| 摘要：该超高压泵是对设计要求很高的一台200Mpa的手提式超高压增压泵，该超高压增压泵结构紧凑，它的效率和可靠性十分重要。本次设计的超高压液压泵需要满足4次达到200Mpa的效率，为了达到这个效率其各个部分的密封性十分重要，一旦有任何一处发生泄漏，就无法满足4次达到200Mpa的效率。34154 本设计对超高压泵进行了分析，主要分析了泵的分类。由于该设计是一个倍增泵的设计，所以对高压腔和低压腔的精度要求和工艺要求非常高。该设计对效率的要求非常高，所以对密封性也提出了较高的要求。其中还有一个比较重要的地方就是溢流阀的设置，因为溢流阀的设置关系到了打压压力的大小，打压压力的大小直接影响到超高压手动泵的工作效率。我对其中的一些结构，例如，柱塞的结构进行了分析和设计，其中还 包括它们的受力分析与计算。还有对缸体的材料挑选以及校核很关键。本设计最后对柱塞泵的工艺性和优缺点进行了分析，其中的重点进行了总结。 毕业论文关键词：超高压；手动泵；效率 Design and analysis of ultra high pressure pump Abstract：The ultra - high - pressure pump is a 200Mpa portable ultra - high - pressure booster pump with a high design requirement. The structure of the ultra - high - pressure booster pump is compact, and its efficiency and reliability are very important. The design of super high pressure hydraulic pump need to meet 4 times up to 200MPa efficiency, in order to achieve the efficiency of the various parts of the seal is very important, if there is any one place leakage, will not be able to meet 4 times up to 200MPa efficiency. The design of the ultra high pressure pump is analyzed, the main analysis of the pump classification. Since the design is a design of the pump, so the high pressure chamber and the low-pressure chamber of the accuracy requirements and process requirements is very high. The design of the efficiency of the requirements is very high, so the sealing of the higher requirements. The size of including a more important place is relief valve settings, because of the relief valve set in relation to the size of the pressure, pressure, pressure, pressure is directly affect the ultra high pressure hand pump work efficiency. I have some of the structures, for example, the structure of the plunger was analyzed and designed, which also includes their force analysis and calculation. There are also the material selection and verification of the cylinder is critical. In the end, the design of the piston pump and the advantages and disadvantages of the process of the analysis, the focus of the summary.
