기어펌프를 이용한 선박용 유압 액츄에이터 설계에 관한 연구

Valve remote control system(VRCS) is a convenient system which make it possible to operate the valves installed in the cargo or ballast tanks from the remote wheelhouse using only push buttons on the central control console. The actual positions of valves are normally displayed on a mimic panel. VRCS is consisted of many parts such as a control console, a interface panel, a hydraulic power pack, a solenoid valve rack, a deck box and valves with hydraulic actuators. Thus, this study designed a new hydraulic actuator using gear pump. Its main components are a gear pump, an AC motor, a check valve, a relief valve and a controller. Therefore, the developed VRCS has a simply structure such as a control console, a interface panel and valves with new hydraulic actuators.
