Reform of Mechanical Shaft Sealing Self Flush System of Petrochemical Hot Oil Centrifugal Pump

摘要：

　　Mechanical seal leakage of centrifugal pumps (especially hot oil pumps) is the main fault reason of the petrochemical equipments.The fuction of the sealing flush system is to maintain the mechanical shaft seal function correctly.The misconduct of flush system settings will directly lead to the failure of mechanical seal.In this paper,the problems are analyzed for the present mechanical seal flushing system.When the centrifugal pump is in a standby state,flushing system may not provide normal flush flow in self flush plan.This may lead to surface fouling of the hot mechanical shaft seal,resulting in seal failure.Our research focus on solving these problems.The way is to change the source of flush fluid,that is to change the flush plan to external flush plan or toChange the fluid pipe position.
