Design and Application of Steam Driven Lubricating Oil Pump for Steam Turbine Units in Thermal Power Plants
At present,the spindle driven oil pump and electric main oil pump systems used in steam turbine units of thermal power plants cannot achieve oil supply in emergency situations.In order to ensure the safe shutdown of the unit in the event of a power outage in the entire plant,this article utilizes waste heat steam from the boiler superheater,reheater,bypass,and other pipelines to drive a small turbine to sup-ply energy to the lubricating oil system.The dynamic characteristics of the boiler shutdown residual steam source were studied,and the operating time of the steam driven oil pump was calculated.The final designed steam driven oil pump can be quickly started in case of emergencies,Ensure the stability of oil pressure and temperature in all parts of the system during emergency shutdown.
