Question: (DMTO) Olefin separation unit: Conditions that must be met before starting the turbine: (1) The sealing system is already in operation ； (2) The oil system is in operation with normal oil temperature ； (3) The rehydration system is operating normally ； (4) Steam pipeline heating is complete and satisfactory ； Note: The answers will be released automatically in two days!
① The pipes are properly warmed, the steam pressure during startup is normal, and the steam temperature is appropriate (with a low cylinder temperature, the required steam temperature can also be lower)； ② Create a certain vacuum (referring to condenser-type units) ； ③ Establish a certain level of siphon effect (referring to the vacuum level of the condenser outlet water) ； ④ The oil system is operating properly (including oil tank level, oil pressure, oil flow, etc.), and the oil temperature is not below 20°C. ⑤ The turning operation should be carried out continuously; on units without a continuous turning device, the turning handle should be removed.

The initial parameters of the steam should meet the requirements for startup; the shaft wobble value should be within the specified range when the machine is in the barring mode; the temperature difference between the upper and lower cylinders should be between 30 and 50 degrees Celsius.

Before starting the turbine, the following main conditions must be met: ① Proper pipe warming, with normal steam pressure for startup and an appropriate steam temperature (if the cylinder temperature is low, the required steam temperature can also be lower)； ② Create a certain vacuum (referring to condenser-type units) ； ③ Establish a certain level of siphon effect (referring to the vacuum level of the condenser outlet water) ； ④ The oil system is operating properly (including oil tank level, oil pressure, oil flow, etc.), and the oil temperature is not below 20°C. ⑤ The turning operation should be carried out continuously; on units without a continuous turning device, the turning handle should be removed.
