摘要
针对某蓄能水电厂水导轴承存在振动摆度偏大、瓦温偏高、部件异常受损及破坏等问题,经分析得出主要原因为水导轴承泵工况的实际载荷大于原设计载荷。根据该原因提出两种改造方案,并比较选出最优方案,即增加水导瓦的受力面积、降低了水导瓦内径、增加抗重块直径、将抗重块线性平面支撑方式改为球面支撑方式。后续按照该方案改造实施,有效降低瓦温和减小机组摆度从而提高设备可靠性,保证了设备的安全稳定运行。
For the water-conducting bearing of a storage hydropower plant,there are problems such as large vibration swing,high temperature of the tile,abnormal damage and damage of components.After analysis,the main reason is that the actual load of the water-conducting bearing pump is greater than the actual load.Original design load.According to the reason,two reforming schemes are proposed,and the optimal scheme is selected by comparing the force receiving area of the water guiding tile,reducing the inner diameter of the water guiding tile,increasing the diameter of the anti-weight block,and changing the linear plane supporting method of the antiheavy block.Spherical support.Subsequent implementation of the scheme can effectively reduce the temperature of the tile and reduce the pendulum of the unit to improve the reliability of the equipment,ensure the safe and stable operation of the equipment,and provide reliable conditions for the stable operation of the system,thus bringing considerable economic benefi ts to the company and the power grid.
