| Abstract: | Super-high pressure auto-frettage is an effective method to prolong the service life of fracturing pump fluid end. The existing Super-high pressure auto-frettage technology was analyzed. Based on the analysis of the existing super-high pressure auto-frettage technology, it was confirmed that the stress concentration of the key positions in the inner cavity of the hydraulic end valve box was significantly improved after the ultra-high pressure auto-reinforcement according to the existing technology. The fatigue life of the fluid end of the fracturing pump has been effectively extended. According to the simulation analysis, the existing process was optimized, and some problems t in the process of auto-frettage technology were put forward. |
