Study on the Structural Optimization of Diffuser Guide Vanes for LNG High-Pressure Pump Expander

The guide vanes of the high-pressure pump at the Jingtang LNG receiving station frequently fail， potentially generating metal fragments that threaten the safety of downstream systems.In order to extend the service life of the guide vanes， ANSYS software was used to establish a model and conduct stre...
