艉軸密封裝置的常見的產(chǎn)品 船舶艉軸密封裝置,是船舶軸系的主要部件 之一,其性能的好壞直接影響到船舶的正常營運和經(jīng)濟性。同時,對防止船舶污染水域、保護環(huán)境起著十分重要的作用。隨著海洋防污染要求日益嚴格和船舶大型化、高速化及深水作業(yè)等所帶來的密封裝置損壞事故的不斷發(fā)生,國內(nèi)外造船界和航運部門對其可靠性、可維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 密封環(huán)時刻將空氣排向海水一側(cè),再加上2#3#環(huán)的密封壓力通過氣壓得到了控制,所以,無論吃水狀態(tài)有無變化,負荷部很小,而且保持在一定的水平上,因此,每個密封環(huán)的壽命比以往都大幅度地延長,此外,3#密封環(huán)作為備用密封環(huán)被裝備在此裝置內(nèi)。 由于使用了流量的流量控制器,所以空氣耗量極少,通常為20～40Lmin,最大不超過50Lmin,因此船內(nèi)原有的控制空氣容量足夠用來消耗 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
