Abstract
Feed water pump seal water system of feed water pump bearing lubrication
cooling
prevent the action of high temperature and high pressure water leak
feed water pump seal water system control is bad can lead water into lubricating oil system
the water of the feed water pump and the normal operation of the steam pump caused great harm
this article analyzes the system structure and the labyrinth steam feed water pump shaft end pump shaft seal system structure of 600 mw thermal power unit steam pump was discussed the various causes of lubricating oil into the water
by system of feed water pump seal structure and the renovation of the steam pump shaft seal system
and optimize the operation mode
solved the problem of the Feed water pump oil system into the water.
