Siphonic Power Oil Return Scheme for Turbine Bearing Pedestal
摘要
Abstract
The oil return system is a critical guarantee for the operation safety of steam turbine generator set.Traditionally,natural gravity method is adopted in oil return for bearing pedestal,which is simple in principle and relatively stable in operation,but the oil return efficiency is relatively low,and it has high requirements for pipeline layout,bearing flow rate,etc.The obstruction during return of lubricating oil will lead to disturbance of oil in bearing pedestal,which may cause damage to key equipment or even unplanned shut down.Accordingly,a novel return method using a siphon tube for high-speed return is proposed.This scheme has higher efficiency and can offer more convenient layout.Its implementation in a project demonstrates the feasibility of this approach,providing reference for efficient oil return of bearing pedestal in various steam turbines.关键词
