STUFFING BOX ANALISYS BASED ON SYSTEM DYNAMICS APPROACH
Mots-clés :
stuffing box seal, system dynamics, modeling, optimizationRésumé
The stuffing box seals are widely used in industry despite to their main drawbacks like their high power loses due to the friction between teh shaft and the gasket and the increase of the leakage during the functioning, due to a decrease of the tightening force. In order to minimize these ones, an optimized over-tightening time schedule must be used. The paper present a new approach of the stuffing box seals problem, treated as dynamic systems, allowing to model and simulate their functioning. By this way, the optimal over-tightening time may be established, allowing to obtain the best performances of the seal.
