摘要
田湾核电站采用水润滑轴承,在核电厂运行中轴承释热率一直偏高,轴瓦存在较严重的磨损。针对主泵轴承的出现的问题,采用计算流体动力学(CFD)方法分析主泵轴承动静轴瓦之间微小空间内流体的流动特性和压力分析。分析表明:主泵轴承释热率偏高和频繁磨损的根本原因是轴承室空化汽蚀;空化汽蚀的发生是由局部区域的流动加速效应引起的。
Water is used as the lubricant for the axletree by Tianwan nuclear power plant. The heat generation by rate is on the high side, and serious abrasion is found on the axletree. The paper studies the characteristics of the flow and pressure in the axletree room by computed fluid dynamics （CFD） method for the abrasion of the axletree. Analysis shows that the reason for the abrasion and high heat generation rate of the axletree is cavitation; and the cavitation is caused by the flow acceleration effect of local area.
