DESIGN DEVELOPMENT AND TRIBOLOGY OF RECIPROCATING HYDRAULIC SEALS

Abstract

The development of reciprocating hydraulic seals is the simultaneous progress of seal designs and their tribo-mechanical system. The progress is resulted by the improvements in seal material characteristics, technology and design (cross section form, seal edge shape, friction surface quality, etc.), lubrication conditions, accuracy, reliability and life. Anyhow by time the increasing importance of environmental protection gave particular emphasis to leakage control. In these developing processes emphasized aims are to economize by reducing losses - both leakage and friction - and also reducing the required sealing space (housing volume), while adequate and reliable sealing life is obtained. The present paper provides contribution in revealing tribological - mostly friction - characteristics, design and efficiency of some characteristic reciprocating hydraulic seals.
