Latest Patents
Dumas holds a patent for a **positive displacement pump utilized in lube oil systems for turbomachinery**. This invention discloses a backup lube oil pump system for steam turbine lube oil systems. The prior art systems typically included a primary centrifugal pump attached to the turbine shaft, alongside AC and DC motor-driven pumps for lubrication during startup and shutdown phases. However, during an AC power failure while the turbine is coasting down, the AC backup pump becomes inoperative. The new positive displacement design addresses this critical vulnerability by utilizing a rotor-driven permanent magnet generator. This reliable solution ensures continuous oil flow to the shaft bearings, even at lower speeds, thus preventing potential bearing damage.
