The invention provides a container ship stern tube sealing system which comprises a ship draft gauge pressure monitoring unit, a valve pressure control unit and a stern tube sealing pressure execution unit, the ship draft gauge pressure monitoring unit is connected with the valve pressure control unit, the valve pressure control unit is connected with the stern tube sealing pressure execution unit, and the stern tube sealing pressure execution unit is connected with the ship draft gauge pressure monitoring unit. The ship draft gauge pressure monitoring unit is used for monitoring draft pressure signals, the valve pressure control unit is used for receiving the draft pressure signals and air pressure signals and controlling the motion of the stern tube sealing pressure execution unit, and the stern tube sealing pressure execution unit controls the air pressure and the oil pressure in the system to preset values through corresponding valve groups. The ship draft indicator does not need to be purchased additionally, the manufacturing cost is low, the stern tube airtight sealing system is dynamically adjusted according to the ship draft pressure, the air pressure and oil pressure difference is controlled, and the service life of a sealing ring is prolonged. Meanwhile, when the air seal breaks down, the tail shaft seal can still automatically and normally operate, and the reliability of the system is improved.
本发明提供一种集装箱船艉管密封系统,包括船舶吃水计压力监测单元,阀门压力控制单元和艉管密封压力执行单元,船舶吃水计压力监测单元与阀门压力控制单元相连,阀门压力控制单元与艉管密封压力执行单元相连,船舶吃水计压力监测单元用于监测吃水压力信号,阀门压力控制单元用于接收吃水压力信号和空气压力信号并控制艉管密封压力执行单元的动作,艉管密封压力执行单元通过相应的阀组控制系统内的空气压力和油压至预设值。本发明所采用的船舶吃水指示计无需另外采购,造价低,根据船舶吃水压力动态调节的艉管气密封系统,控制气压和油压差,提高密封环使用寿命。同时,气密封有故障时,艉轴密封仍能自动正常运行,增加了该系统的可靠性。
