汽轮机组膨胀受阻原因分析及处理

Cause Analysis and Treatment of Expansion Obstruction of No.2Steam Turbine unit

滑销系统是汽轮机在运行和启停过程中膨胀与收缩的重要组成部分,是保持汽缸与轴承箱、汽缸与转子的相对中心位置不变的重要部件。滑销系统的好坏是保证汽轮机安全运行的重要条件之一,机组膨胀受阻与滑销系统应用不良息息相关,对解决机组膨胀问题意义重大。

Sliding pin system is an important part of expansion and contraction of steam turbine during operation and start-up and shutdown.It is an important part to keep the relative center position of cylinder and bearing box,cylinder and rotor unchanged.The quality of sliding pin system is one of the important conditions to ensure the safe operation of steam turbine.The blocking of unit expansion is closely related to the poor application of sliding pin system.It is of great signifi cance to thoroughly solve the problem of poor expansion of the unit.
