Catalytic main fan – booster pump shut down

After shutting down, it needs to be enabled for a few hours before it can be turned off again
It is necessary to wait until the temperature of each bearing has dropped before stopping, otherwise the equipment is prone to damage.
The lubricating oil system needs to run for a few more hours; once all temperatures have dropped, the lubricating oil should be shut off to prevent high temperatures from causing deformation of various components.
Even with ordinary mechanical pumps, the lubricating oil remains after they are shut down; it’s just that devices such as oil injectors or oil cups are used for this purpose, and we don’t pay much attention to it! Not to mention these large-scale unit equipment?
It must run during shutdown; once the temperature reaches normal levels, the pump can be stopped. Here, it is required that the lubrication pump be turned on while the pump is being rotated.
That’s necessary; the bearing temperature must be reduced to normal levels before it can be stopped
Why is there doubt about this? ? This should be a basic common sense question, right?
When the unit stops, the heat from the shaft concentrates on one side; therefore, the heat must be removed using lubricating oil, and the shaft must be prevented from bending through shaft turning.
