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.
