[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.
