After the DGT600-250 steam feed pump produced by Shanghai Electric Power Repair and Repair Plant was returned to the factory for repair

the thrust tile temperature continued to rise during the trial and test. When the unit load exceeded 160 MW

the thrust tile temperature exceeded the alarm 1 value

and As the load increases

the thrust tile temperature continues to rise. By analyzing the problems of lubricating oil pressure

oil temperature

flow rate

oil path

etc.

the cause of thrust tile temperature high is found out

and effective treatment measures are proposed to solve the thrust tile temperature is high on-site puzzles.
