Abstract
A flushing system for flushing away any coking material which may have built up in the bearing of a gas turbine. Three fluid tanks respectively contain a solvent for dissolving the coked material, a cleaner and a lubricant. By means of a three-way valve, one of the fluids is provided to a supply pump for delivery to the bearing housing via a quick disconnect coupling. Fluid is returned to the appropriate tank by means of a return pump, via a quick disconnect coupling and another three-way valve between the return pump and the tanks. The system includes respective filters for filtering the return fluids and the entire system may be carried on a wheeled cart for servicing the gas turbine.
