Fatigue Prediction for Pump End of High Pressure Fracturing Pump

Abstract:

Article Preview

The unexpected in-service failure of fluid pump end of fracturing pump motivated the present investigation. The model of three-cylinder single-action fluid pump end had been established by using the Pro/E software for improving the level of fracturing pump design. The combined use of fracture mechanics concepts as well as the finite element method demonstrated that local failure was due to the specific intersection region between plunger-chamber and cylinder-cavity. The predicted fatigue lives based on the FE stress analysis agree well with the application observations.
