摘要

针对某电厂哈尔滨汽轮机厂N1000?32/600/620/620型百万千瓦二次再热机组冷态冲转至48.6r/min时突发剧烈振动、#1～#4轴承振动瞬间满量程并触发跳机

伴随#2、#3轴瓦碾瓦、垫块碎裂及顶轴油系统异常的典型故障

结合哈汽同类型机组普遍存在的低速振动共性问题

从轴系结构、滑销膨胀、顶轴油特性、动静间隙及转子残余不平衡等维度

系统开展故障机理溯源与耦合作用分析。通过现场解体检查、轴系精测、顶轴油系统全流程整治、滑销间隙校正、启机曲线优化及现场动平衡校正等综合治理措施

机组再次启动一次成功

各轴承振动长期稳定在优秀范围。研究成果与治理经验可为国内同类型哈汽二次再热机组启机振动治理提供工程参考与实践依据。

Abstract

This study investigates a typical failure occurring in the N100032/600/620/620 MW secondary reheat units at Harbin Steam Turbine Plant of a power plant

where severe vibration emerged during cold startup at 48.6 r/min

with bearings #1–#4 reaching full range vibration and triggering unit shutdown

accompanied by bearing seizure in #2 and #3

pad fracture

and abnormalities in the journal oil system. Addressing the common low-speed vibration issues prevalent in similar Harbin Steam units

a comprehensive analysis was conducted covering aspects such as shaft structure

sliding pin expansion

journal oil properties

dynamic-static clearance

and rotor residual imbalance to trace fault mechanisms and analyze coupling effects. Through integrated measures—including on-site disassembly inspection

precise shaft measurement

full-process improvement of the journal oil system

sliding pin clearance adjustment

startup curve optimization

and dynamic balancing calibration—the unit was successfully restarted after one attempt

with all bearing vibrations remaining consistently within optimal ranges. These findings provide valuable engineering references and practical guidance for vibration control in domestic secondary reheat units of similar configuration.
