90. Under what circumstances does the unit shut down urgently?
1. If the unit meets the conditions for automatic shutdown due to interlock failure but does not shut down, perform a manual emergency stop. 2. If the unit experiences severe vibration, smoking from the shaft seals or bearing shells, or other friction-related noises. 3. In the event of serious leaks in the power oil system or lubricating oil system, and when it is not possible to replenish the oil level in the tanks. 4. If a large amount of leakage in the oil circuit system leads to a fire. 5. If the temperature of the bearing shells exceeds the alarm threshold and it is not possible to prevent further rise in temperature. 6. If the fan experiences surge, and the surge valve cannot be opened during attempts to resolve the issue, then perform a manual shutdown.
If the unit meets the conditions for automatic shutdown due to self-protection mechanisms but does not shut down, perform a manual emergency shutdown. In cases of severe vibration in the unit, smoking from the shaft seals or bearing shells, or other friction-related noises; in situations where there are serious leaks in the power oil system or lubricating oil system and the oil tank level cannot be replenished; when the temperature of the bearing shells is high, exceeding the alarm threshold and unable to be brought down; or when the fan experiences surge and the surge valve cannot be opened during attempts to address the issue, a manual shutdown should be carried out.
