What is the primary function of the turbine auxiliary oil pump?

The primary function of the turbine auxiliary oil pump is to establish oil pressure during turbine start-up. This is critical because, during start-up, the turbine requires a certain level of oil pressure to ensure that the system can effectively lubricate and cool its components. Without adequate oil pressure at start-up, there is a risk of insufficient lubrication, which can lead to wear and damage to vital components of the turbine. The auxiliary oil pump plays a crucial role in providing this initial pressure, allowing for a safe and reliable start-up of the turbine system.

While cooling turbine components, maintaining lubrication during operation, and controlling turbine speed are all important functions in the overall operation of a turbine, they are not the primary focus of the auxiliary oil pump at the point of start-up. The emphasis here is on enabling the necessary oil pressure to kickstart the lubrication process effectively.
