Through the analysis of the macromorphology and microstructure of the fracture, the analysis of the chemical compositions of shaft material, the metallographic test of the specimens cut from the fracture, the investigation of the operating condition of the pump, the main reason for the fracture can be described as the increased rotating and bending load caused by low viscosity medium. Corresponding preventive measures were put forward. 1 Process safety progress ARTICULO Xu, Shugen 59761 Zhang, Yuan 50032 Wang, Chong 59762 Sun, Zhiwei 59763 Wang, Shengkun 59764 Zhao, Yanling 59765 193606 193606 0 0 0 0 261325 BAAB BAAB 2026-03-06 200065968 0 200065968 2026-03-06 00:38:35 2026-03-06 ARTICULO
