20130272845 | AXIAL COMPRESSOR AND CONTROL METHOD THEREOF TO STABILIZE FLUID - A fluid stabilizing control method of an axial compressor is provided, which includes driving to drive the axial impeller, and stall controlling to suppress or prevent an occurrence of a stall that may transpire during rotation of the axial impeller by supplying highly-pressurized compressed air into the casing through a stall controller according to a predetermined time and volume. Accordingly, a stall may be suppressed or prevented, the occurrence of a stall that may transpire when a threshold point is exceeded by an unexpected event during driving in a low-flow high-pressure section on a performance curve, in which efficiency is high. Additionally, since an air injection method for suppressing the stall is properly applied, an amount of power expended for the stall control may be reduced while supply of the high-pressure compressed air is minimized, thereby achieving economically feasible stall control. | 10-17-2013 |
