MARINE SHELL DOOR INCLUDING HYDRAULIC ACTUATOR UNIT |
摘要 |
Marine shell door comprising a framework including a door plate. The framework provides a skeleton structure to reinforce the shell door. Typically, the framework includes a plurality of compartments. The marine shell door is improved in that it further comprises at least one hydraulic actuator unit (10) for operating said shell door itself and/or at least one shell door component. The hydraulic actuator unit comprises a hydraulic actuator (11) and an actuator pump (15) which is dedicated to said hydraulic actuator for operating said hydraulic actuator. The actuator pump has an electrical motor (151) and a pump housing (152) for supplying hydraulic fluid to the hydraulic actuator to operate the shell door. Advantageously, the installation of the shell door on board of a ship is improved. The shell door has no long stainless steel fluid conduits which are difficult to mount during installation and vulnerable to damages in operation. |
