What are the reasons that can cause changes in the temperature of the lubricating oil in condensing steam turbines?

1. Water flow in the cooler. 2. Heat conduction from the steam at the shaft ends (poor performance of the shaft end seals or insulation baffles). 3. Scaling in the cooler. 4. Blockage or too small size of the oil return port in the bearing housing, which hinders heat dissipation from the bearings and leads to an increase in oil temperature.
