应用先进的传动装置设计改善船舶总经济性

An Advanced Transmission Equipment for Total Economical Marine Gain

本文阐述应用先进的传动装置设计来改善船舶在低航速时的经济性。例如远洋船舶及双螺旋桨供给船采用不同功率的柴油机并车装置,可使船舶在低速航行时主机保持在额定工况下运转,从而使船舶保持在最佳燃油消耗率航行。分别阐述了改进船用发电机组的传动方案及采用废气涡轮推动发电机组,提高其运行经济性。在螺旋桨转速变化时,采用RCF恒速系统的必要性。介绍了安装简单干净紧凑的Neat FIF系统和轴隧道传动装置的应用,可缩短机舱长度及充分利用狭窄的船尾舱,从而达到缩短船舶总长度或者增加货舱长度,而增加装货量。指出当今的传动装置设计者必须摆脱单纯的本身技术性的研究,而应对整个推进系统进行全面的研究,才能在提高船舶总经济性方面做出贡献,并成为船厂和船东的亲密伙伴。

This paper describes an advanced transmission (?)equipment which ensures the propulsion engines to run at an economic rated condition with the ships at low speed.It presents the transmission equipment schemes for modifying marine generator sets and deals with the application of the exhaust turbine driven generator sets which are characterized by significant economic operation results.A new power plant design and a tunnel type transmission are also delineated in the paper.
