艉轴密封装置的常见的产品 船舶艉轴密封装置,是船舶轴系的主要部件 之一,其性能的好坏直接影响到船舶的正常营运和经济性。同时,对防止船舶污染水域、保护环境起着十分重要的作用。随着海洋防污染要求日益严格和船舶大型化、高速化及深水作业等所带来的密封装置损坏事故的不断发生,国内外造船界和航运部门对其可靠性、可维修性等提出了更高的要求 Ship stern shaft sealing device, is one of the main components of ship shaft, the stand or fall of its performance directly affects the normal operation of the ship and the economy. At the same time, the prevention of pollution by vessels in waters, protect the environment plays a very important role. Strictly day by day along with the Marine pollution prevention and ship large-scale, quick running, and deep-water brought about by the sealing device damage accidents occur repeatedly, shipbuilding industry and shipping department at home and abroad for its reliability, maintainability, etc. Put forward higher requirements 密封环时刻将空气排向海水一侧,再加上2#3#环的密封压力通过气压得到了控制,所以,无论吃水状态有无变化,负荷部很小,而且保持在一定的水平上,因此,每个密封环的寿命比以往都大幅度地延长,此外,3#密封环作为备用密封环被装备在此装置内。 由于使用了流量的流量控制器,所以空气耗量极少,通常为20～40Lmin,最大不超过50Lmin,因此船内原有的控制空气容量足够用来消耗 Sealing ring moment will air discharge to the sea side, plus 2 # 3 # ring seal pressure through air pressure under control, so, no matter have draft state without change, the load is small, and keep in a certain level, therefore, each ring than ever greatly extend the life of a, in addition, 3 # sealing ring as the standby sealing ring is equipped in this device. Because using the traffic flow controller, air consumption of few, usually for 20 ~ 40 lmin, not more than 50 largest lmin, so the ship to the control of the original air capacity is enough to consume
