舰用蒸汽动力装置回汽刹车与回汽保护技术研究

Study of Back-steam Braking and Back-steam Protection Technology for Marine Steam Power Plants

蒸汽动力舰船变速变向、刹车能力直接影响其机动性,而传统的舰船变速变向及刹车方法存在变速变向不及时、刹车距离过长等缺点,导致舰船机动性不高,危及舰船航行安全性。针对蒸汽动力舰船,介绍了一种能够提高舰船变速变向能力、缩短舰船刹车距离的蒸汽动力装置回汽刹车与回汽保护技术,阐述了该技术的概念与内涵、运用时机、约束条件等,能提高蒸汽动力舰船的机动性,为舰船的安全航行提供帮助。

Speed and direction changing power of the marine steam power vessel has a direct influence on maneuverability of the vessel. Traditional methods for changing speed and direction of the vessels have the disadvantages of being delayed and long braking distance. The disadvantages reduce maneuverability of the vessels, and jeopardize navigation ：security of the vessels. Back- steam braking and back-steam protection technology for marine steam power plants is introduced in the paper to improve the speed and direction changing power and reduce braking distance of the vessels. The paper elaborated concept and connotation, utilizing opportunity, constraint condition of the technology. Back-steam braking and back-steam protection technology can improve maneuverability of the vessels and provide some help for the navigation security of the vessels.
