螺旋桨和船舶推进

船舶推进的终点

CPP

螺旋桨在船上推进系统的最后一部分。

Masson Marine设计,制造和安装所有构成螺旋桨和它的支撑件。这套包括桨轴,整流罩(如果要求)和斯特恩管。我们同时也致力于同齿轮箱的接合。

市场上的专业船舶存在两种类型的螺旋桨:

  • 可调螺距螺旋桨(CPP)或可调桨叶螺旋桨。
  • 固定螺旋桨。

每种桨都有自己的优点和缺点。有关详细信息,请参考以下各节。

为什么使用可调桨叶螺旋桨

OUTLET DRAWING CPP

现代船只都需要但以最低的成本获得更大的收益。

可调桨叶螺旋桨特别适合工作船的工作条件,这些船只需要不同的推进状态,推进速度,牵引性和可操作性(如拖网船,拖船,支援船) 。

他们有许多技术和经济利益上的优势。

CPP的好处

可调桨叶螺旋桨的多种优点中,主要有:

  • 推进性能优于固定螺旋桨,优化速度和牵引力的性能。
  • 更好的机动性:船舶前进到后退的过渡没有死点或冲击,只需通过扭转螺距。响应时间非常迅速,而且船舶保持满动力状态,为船舶及其旅客提供了更好的安全保障,大大减少煞车距离。
  • 更好地利用柴油发动机:在所有情况下,螺旋桨可利用动力保持100%(自由航行,拖网,操作...).此外,CPP可以不间断利用发动机额定转速,从而大幅度降低成本消耗和维护成本同时减少磨损离合器。
  • 可离合式PTO可以带动泵,不可离合式可以带动发电机。
