The invention relates to the technical field of ships, in particular to a marine main engine air duct system and a ship. The marine main engine air duct system comprises a first air duct and a second air duct, an air inlet of the first air duct is communicated with the outside of a ship board, and an air outlet of the first air duct is communicated with a supercharger air inlet of a main engine; an air outlet of the second air duct is connected to the pipe wall of the first air duct; the air brake is rotatably mounted in the first air duct, so that the air brake has a closing position for closing the air outlet of the second air duct and an opening position for opening the air outlet of the second air duct; when the difference value between the pressure P1 in the second air duct and the pressure P2 in the first air duct is larger than the set value P0, the air brake can rotate to the opening position, so that the main engine is prevented from being broken down due to air suction, and the running stability of the main engine is improved. According to the ship, by applying the main engine air duct system for the ship, the situation that the main engine breaks down due to vacuum in the main engine air duct can be avoided, and the running stability of the main engine is improved.
本发明涉及船舶技术领域,尤其涉及一种船用主机风道系统及船舶。所述船用主机风道系统包括第一风道和第二风道,第一风道进风口与船舷外连通,其出风口与主机的增压器进风口连通;第二风道进风口与舱室连通,其出风口连接于第一风道的管壁上;风闸可转动地安装于第一风道内,以使风闸具有关闭第二风道出风口的关闭位置以及打开第二风道出风口的打开位置;当第二风道内的压强P1与第一风道内的压强P2之间的差值大于设定值P0时,风闸能够转动至打开位置,从而避免主机因空吸而发生故障,提高主机运行的稳定性。所述船舶通过应用上述船用主机风道系统,能够避免发生因主机风道内出现真空而使主机发生故障的情况,提高主机运行的稳定性。
