Nitrogen penetration accident in refractory tiles
Thread Content
Due to a UPS failure, the control station lost power when the upstream substation went offline, resulting in the complete destruction of one nitrogen permeation bearing bush.
It’s another UPS failure; why is the quality of UPS units so unreliable these days? It is recommended that the poster use dual UPS power supply. Could you explain any other phenomena in more detail?
The original poster really wrote it too simply, didn’t they? What is a \"nitrogen-penetrated bearing\"? Is it a turbine bearing with nitrogen penetration? Could you explain the process in detail?
Your unit protection system is not comprehensive enough; ideally, a high-level oil tank should be available to supply oil for shutting down the unit in the event of an emergency stop.
