Pay attention to the speed at which the compressor reduces its load. It is essential to maintain a stable rotation speed of the turbine, as well as stability in steam pressure and temperature
Could the brother upstairs be more specific? Is it by gradually reducing the inlet pressure and temperature in order to lower the rotational speed? ?
1: Pay attention to oil temperature, oil pressure, oil pressure difference, and oil level. 2: Unit speed, pressures at various stages, temperature, vibration, inlet steam pressure and temperature. 3: The opening degree of the anti-surge valve and the flow rate. 4: Check for any abnormalities such as leaks. 5: Discharge the level from the separation tank according to the situation.
The most important thing is to prevent surge!
The key principle is to increase the speed first when raising voltage, and to reduce the voltage first when slowing down.
Pay attention to the steam pressure and steam superheat, and try to prevent the surge valve from acting during operation.
