5th INTERNATIONAL MULTYDISCIPLINARY CONFERENCE DEVELOPMENT AND TRIBOLOGY OF RECIPROCATING HYDRAULIC SEALS

Abstract: The development of reciprocating hydraulic seals radically decreased the efficiency and immensely reduced the seal housing volumes and also the overall economy of high pressure hydraulic drives. To reveal tribological behaviour of reciprocating seals it is necessary to analyse the relationships of seal design, tribological features and the main operating characteristics. For environmental protection leakage control has great importance. Leakage calculation of reciprocating high pressure hydraulic seals is based on the sealing pressure distribution profiles, i.e. diagrams which are playing an important role in research and development of piston and piston rod seals too. Key words: tribology of seals, reciprocating hydraulic seals, piston and piston rod seals, efficiency of friction seals, seal design. 1
