Wear Model of a Mechanical Seal Based on Piecewise Fractal Theory

In this research, a model is proposed using piecewise fractal theory that considers abrasive and adhesive wear. The model demonstrated improved wear computation accuracy of a contact mechanical seal end face. The validity of the model was established by comparing the simulation results with experimental data and the conventional MB and Archard models. The loading effect and surface morphology parameters involved in wear were also investigated. Results show that severe wear occurs with increasing load ratio, large fractal dimensions, and a higher scale coefficient of the surface morphology. The findings offer a novel method for precisely calculating and projecting the amount of wear of a contact mechanical seal and predicting its wear behavior.

Automated summary

In this research, a model incorporating piecewise fractal theory is proposed for accurately calculating wear in a contact mechanical seal. The model shows improved accuracy compared to conventional models and is validated through comparison with experimental data. The study also analyzes the effect of loading and surface morphology parameters on wear, finding that severe wear is influenced by increasing load ratio and specific surface characteristics. These findings offer a novel method for predicting and calculating wear in contact mechanical seals.
