(1) There are metallic noises or impacts inside the cylinder； (2) Sudden increase in vibration
1) A sudden noise is generated inside the turbine or the condenser. 2) Sudden increase in vibration or shaking of the unit. 3) When the blades are severely damaged, to maintain a constant load, the steam flow rate must be increased, that is, the valve opening must be enlarged. 4) The condenser water level rises, the conductivity of the condensate water increases, and the current in the condensate pump increases. 5) Broken blades entering the extraction steam pipeline cause valve sticking. 6) A metallic rubbing sound can be heard during coasting and turning operations. 7) The intermediate pressure increases during operation.
(1) There are metallic noises or impacts inside the cylinder； (2) Sudden increase in vibration
Answer: The phenomena associated with turbine blade failure include: 1) A sudden noise occurring inside the turbine or in the condenser. 2) Sudden increase in vibration or shaking of the unit. 3) When the blades are severely damaged, to maintain a constant load, the steam flow rate must be increased, that is, the valve opening must be enlarged. 4) The condenser water level rises, the conductivity of the condensate water increases, and the current in the condensate pump increases. 5) Broken blades entering the extraction steam pipeline cause valve sticking. 6) A metallic rubbing sound can be heard during coasting and turning operations. 7) The intermediate pressure increases during operation.
1. Metallic noises or knocking sounds inside the cylinder. 2. Sudden increase in vibration
1) A sudden noise is generated inside the turbine or the condenser. 2) Sudden increase in vibration or shaking of the unit. 3) When the blades are severely damaged, to maintain a constant load, the steam flow rate must be increased, that is, the valve opening must be enlarged. 4) The condenser water level rises, the conductivity of the condensate water increases, and the current in the condensate pump increases. 5) Broken blades entering the extraction steam pipeline cause valve sticking. 6) A metallic rubbing sound can be heard during coasting and turning operations. 7) The intermediate pressure increases during operation.

There are metal striking sounds inside the cylinder, and vibration increases
(1) There are metallic noises or impacts inside the cylinder； (2) The vibration suddenly increases.
