The jacking oil system in a steam turbine plays a crucial role in supporting the turbine's operation. Its primary functions are:
1. *Lifting and supporting*: The jacking oil system helps lift the turbine rotor off the bearings, allowing it to rotate freely during startup and shutdown. This reduces friction and wear on the bearings and shaft.
2. *Hydraulic jacking*: The system provides hydraulic pressure to position the turbine's rotor and shaft during maintenance, allowing for easier disassembly and reassembly.
3. *Bearing cooling*: The jacking oil system helps cool the bearings by circulating oil through the bearing housings, maintaining optimal operating temperatures.
4. *Lubrication*: The system also provides lubrication to the bearings and other moving parts, reducing friction and wear.
In summary, the jacking oil system ensures a smooth and safe startup, shutdown, and maintenance of the steam turbine, while also providing essential lubrication and cooling functions.
