Application of multicriterial analysis for selection of polymeric seals in hydraulics

Summary

The choice of polymeric seals for water hydraulic systems was the subject of investigations by multicriterial optimization. The criteria of choice were technical factors (mainly durability and tightness, see Fig. 4 and 5), economical ones (energy lost as a result of friction, see Fig. 6 and 7) as well as ecological one (ecoindex 99). After preliminary selection, two types of seals made of PE-UHMW ("Mupuseal”) were chosen. The results obtained show that durability does not follow tightness - the higher tightness the lower durability, and inversely. This regularity is a consequence of two types of seal wear: fatigue one (deteriorating the tightness) and abrasive one (deteriorating the durability). The selection of seals for the given application should take this dependence into consideration.


Key words: water hydraulic, polymeric seals, multicriterial optimization, durability, tightness
