Abstract

In this research, a purifying system using a centrifugal filter equipped with a water separation component has been studied. Oil utilized for lubrication and cooling in marine engines becomes unable to achieve its original purpose over time as the accumulation of solid particles and water increases. Therefore, methods applying the Bernoulli equation to eliminate water in oil were investigated and proposed. As a result, a practical purifying system was designed and tested by an officially certified organization. The new purifying system is anticipated to contribute to the extension of the lifetime of oil in addition to damage reduction methods of mechanical parts.

본 연구에서는 선박 엔진 오일을 여과하는 검증된 기술인 원심정화기(Centrifugal Filter)를 이용하여 수분배출 구조를 설계하고 적용함으로써, 원심 청정기 시스템(Centrifugal Purifier System)을 개발하고자 한다. 선박엔진에서 윤활 및 냉각을 담당하는 오일은 시간이 경과할수록 미세입자 슬러지가 증가하고 때로는 수분의 유입에 따라 원래의 기능을 담당할 수 없게 되어 엔진내부에 치명적인 기계적 손상을 초래한다. 따라서 수분 제거 원리 고안 및 검증, 적절한 배출 구조 설계를 연구하였으며, 개발된 제품은 공인시험을 통해 유효함을 검증하였다. 이는 실제 선박에서 절실히 필요한 엔진 오일의 수명 연장 및 폐오일 감소, 기계 부품 손상 저감 등에 기여할 것으로 기대한다.
