Title:
METHOD AND SYSTEM FOR CENTRIFUGAL PUMP
Document Type and Number:
Japanese Patent JP2017120084
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve a method and system for pumping oil in a gas turbine engine.SOLUTION: A pump 300 includes a first rotatable member 302 including a radially inward facing groove 310 having an edge 308. The first rotatable member 302 receives flows of fluid over the edge 308, and rotates at a first angular velocity 316. The pump 300 also includes a second rotatable member 304 including a collector rotating at a second angular velocity 318 and also including a plurality of scoop tubes 314 extending radially outwardly from the collector. Each scoop tube 314 of the plurality of scoop tubes 314 includes a first end coupled in flow communication with the collector 304, and a second end including an inlet opening extending into the groove 310. The second end is curved such that the inlet opening is open in a direction of rotation of the second rotatable member 304. The inlet opening is configured to scoop a fluid collected in the groove 310.SELECTED DRAWING: Figure 3
