유압 기어펌프의 릴리프 홈 형상 변화에 따른 성능특성에 관한 연구
A Study on the Performance Characteristics for Relief Port Shape of Oil Hydraulic Gear Pump
초록
It is possible for a volume of fluid to become trapped in the space between two adjoining teeth and the tips of the teeth engage in Gear Pumu with involute teeth. This trapped fluid leads to several harmful results, for example fluctuating pressure and aeration of pump. In this study, hence, theoretical and experimental analyses on this 'Trapping' were accomplished as using relief port, one of the means for avoiding it. Also, the grasp and analysis on variational type of the internal pressure in parallel with above experiments are achieved so that hydrodynamic behaviors in pump were contemplated.
