【摘要】：氣動增壓的超高壓泵作為一種動力源綜合了氣動和液壓的特點。它是一種利用兩個串聯(lián)的級差式活塞的面積差將較低的壓縮空氣能轉(zhuǎn)換成較高的液壓能的裝置。氣動增壓的超高壓泵具有結(jié)構(gòu)緊湊、體積小、成本低、節(jié)能、使用與維護方便等特點。 本論文以氣動增壓的超高壓泵為研究對象。基于增壓泵的增壓原理和課題中對于增壓泵的設(shè)計要求,進行理論計算及特性分析。通過對國外同類增壓泵的測繪,消化吸收其先進的技術(shù),對增壓泵進行結(jié)構(gòu)設(shè)計和材料選擇。根據(jù)結(jié)構(gòu)特點和國內(nèi)密封標(biāo)準(zhǔn)選擇增壓泵的密封形式和密封件材料。利用三維建模軟件solidworks對增壓泵進行整體建模,繪制加工圖紙以及確定零件的加工精度等。為了達到最優(yōu)化的設(shè)計方案,對氣動增壓的超高壓泵的低壓缸部件進行有限元的結(jié)構(gòu)靜力學(xué)分析計算。根據(jù)分析的應(yīng)力和位移結(jié)果,對不合理的結(jié)構(gòu)進行拓?fù)鋬?yōu)化計算。根據(jù)各部件的受力情況和拓?fù)鋬?yōu)化結(jié)果對部件進行結(jié)構(gòu)的優(yōu)化設(shè)計,設(shè)計出結(jié)構(gòu)合理滿足使用工況的氣動增壓的超高壓泵。
[Abstract]:As a power source, pneumatic supercharged ultra-high-pressure pump integrates the characteristics of pneumatic and hydraulic. It is a device for converting lower compressed air energy into higher hydraulic energy by using the area difference of two series differential piston. Pneumatic supercharged ultra-high pressure pump has the advantages of compact structure, small volume, low cost, energy saving, convenient operation and maintenance. In this paper, the pneumatic supercharged super-high-pressure pump as the research object. Based on the pressurization principle of the booster pump and the design requirements of the booster pump, the theoretical calculation and characteristic analysis are carried out. By surveying and mapping the same kind of booster pump abroad, digesting and absorbing its advanced technology, the structure design and material selection of the booster pump are carried out. According to the structure characteristics and domestic sealing standard, the seal form and sealing material of booster pump are selected. Three dimensional modeling software solidworks is used to model the booster pump, draw the machining drawings and determine the machining accuracy of the parts. In order to achieve the optimum design scheme, the structural statics analysis and calculation of the low pressure cylinder parts of the pneumatic supercharged ultra-high pressure pump are carried out by finite element method. Based on the results of stress and displacement analysis, topological optimization of unreasonable structures is carried out. According to the force situation of each component and the result of topology optimization, the structural optimization design of the components is carried out, and the super-high pressure pump with pneumatic supercharging is designed.
