600WM火电机组低压缸轴瓦振动异常分析及处理

摘 要：我公司低压缸轴瓦选用四瓦块可倾瓦，因轴瓦顶部间隙、轴瓦紧力调整不合理、轴瓦垫铁接触不良、轴承负载不均等原因，造成轴瓦振动异常、上瓦块进油边角落有钨金损坏。通过合理调整轴瓦顶部间隙、轴瓦紧力；研刮垫铁、调整轴承载荷等措施，避免了低压缸轴瓦振动异常及钨金损坏现象的发生。

[Abstract] My company low pressure cylinder bearing selection four pad tilting pad bearing, bearing clearance, because the top tension adjustment is reasonable, bearing pad iron bad contact, bearing load is not equal, resulting in bearing abnormal vibration on the tile, oil inlet side corner with tungsten damage. By reasonably adjusting the bearing top clearance, bearing force; scraping adjustment shim, a bearing load and other measures, avoid low pressure cylinder bearing abnormal vibration and damage phenomenon of tungsten.
