| Abstract: | By analyzing 3D steady flow field of a PG20L80-65-250 high-temperature high-pres- sure canned motor pump, this paper uncovers the internal flowing rules of high-temperature high- pressure canned motor pump such as pressure distribution and cavitation characteristics, which pro- vides the theoretical guidance for optimization design of this kind of hydraulic models in aspects of improving efficiency and reducing vibration and noise. Based on comparative analysis between simu- lation result and test result, it is also known that this simulation method has smaller error. The mod- el experiment can be replaced by simulation result to reduce experimental expenses of high-tempera- ture high-pressure canned motor pump and save the cost. |
