Why the thrust bearing is damaged and the vacuum emergency stop is destroyed? 2020-03-26


Thrust bearing is the fixed axial position of the turbine rotor and the cylinder, and it bears the axial thrust of the rotor during operation. Generally, the axial clearance of the thrust disk in the thrust bearing plus the thickness of the thrust Waukin is less than the shaft of the turbine flow passage Minimum clearance between moving and static. However, the negative differential expansion limit of the medium-pressure cylinder of some units does not consider the consequences of Wujin's wear-out, that is, Wujin burns out, frictional collision between the axial and dynamic parts of the turbine's flow passage may cause friction and damage the equipment. If the machine is not stopped at the fastest speed, The consequences are unthinkable, so a damaged thrust bearing will destroy the vacuum emergency stop.
