| Affiliation: | To solve the problem of 1 000 MW ultra super-critical unit boiler feed pump turbine emergency AC/DC lubricating oil pumps apply oil slowly and cannot reach alternate function in the process of normal operation. We analyzed and deeply discussed all related factors,e.g.,lubricating oil pumps incapable of sucking oil,the blocked bearing chamber respirator,measuring element failure,the string of lubricating oil pump shaft moving,etc.,and provided the basis for accurately determining the reasons why the AC/DC lubricating oil pumps apply oil slowly. By examining the process phenomena and the actual installed system and equipment,further analysis and investigation were performed and the key factors causing the emergency AC/DC lubricating oil pumps to apply oil slowly were determined. Then we put forward and carried out the optimization scheme that adds an exhaust line and a valve in oil return pipe,and an orifice in every lubricating oil pump shell,and adjusts the movement of every lubricating oil pump. In the end,the problem of slow oil supply from Emergency AC/DC Lubricating Oil Pumps was solved. |
