一种用于立轴水轮发电机的辅助油槽结构
本技术涉及水轮发电机
,尤其涉及了一种用于立轴水轮发电机的辅助油槽结构的设计。
技术介绍
立轴水轮发电机的推力瓦及导瓦的温度高低,直接影响机组运行的稳定性及可靠性。推力瓦及导瓦的温度主要靠油槽里的油进行冷却,因此油槽的大小对油槽油温有着异常重要的作用。目前,推力及导轴承油槽是单油槽,通常布置在下机架(或上机架)中心体内。常规的油槽结构单一,瓦温的高低取决于油槽的油温,理论上油槽的容积越大,相对的油温将会越低,但是由于空间的限制,油槽的容积受限多,很难加大。如果设计瓦温太高,需要增大油槽时,就必须相应的增大机架的体积,从而大大的增加了制作加工成本和运输成本。有时由于运输或机组尺寸的限制,油槽容积无法增大,存在推力瓦或导瓦温度偏高的风险。
技术实现思路
本技术针对现有技术中油槽容积小,存在温度偏高的风险的缺点,提供了一种用于立轴水轮发电机的辅助油槽结构。本专利技术解决了油槽容积小的问题,本设计方案在常规油槽的基础上,增加了一个辅助油槽与之连通,不需要增大常规油槽的体积就能达到加大油槽的作用,大大降低了成本,并达到降低油温的效果,使瓦 ...
