国外汽轮机保安和润滑油系统的新设计

New Design of Overseas Turbine's Security and Lubrication Oil System

近年来从国外引进的大型汽轮机保安系统大都采用了无机械危急遮断器的设计 ,超速跳闸是通过电气装置实现的 ;而润滑油系统未设计主轴拖动的主油泵 ,是通过 2台交流润滑油泵的相互备用实现润滑油的可靠供应。

The majority of turbine security system that introduced from abroad adopts no machinery crisis interpeter's design, and realizes super speed trip with eletric installation.Lubrication oil system's chief oil system's chief oil pump can't drive by main shaft,and realizes lubrication oil's reliability supply with two alternation lubrication oil pump's mutually reserve.The paper introduces these ideas for our nation's turbine desigh and improvement.
