Final answer:
Oil screens or filters in a turbine oil system are typically located on the suction side of the oil pump and possibly on the pressure side, ensuring contamination is removed before reaching critical components.
Step-by-step explanation:
In a turbine oil system, oil screens or filters are crucial components designed to remove contaminants from the oil before it reaches critical moving parts. These filters are most commonly located on the suction side of the oil pump to protect the pump from large particles and possibly on the pressure side to ensure finer filtration before the oil is delivered to the bearings and other components.
Sometimes, there might be additional filters placed inline further downstream to provide additional cleaning as needed. It is essential for the maintenance of the turbine system that these filters are regularly checked and replaced when necessary to prevent wear and tear on the turbine components and to ensure efficient operation.
