20130302155 | CENTRIFUGAL COMPRESSOR AND MANUFACTURING METHOD THEREOF - A centrifugal compressor includes an impeller, a casing, an impeller housing portion, an inlet port, an annular flow passage provided around the impeller, a discharge port communicated with the annular flow passage, an annular chamber provided around the inlet port, a downstream slot communicating a downstream end of the annular chamber with the impeller housing portion, and an upstream slot communicating an upstream end of the annular chamber with the inlet port. The downstream slot draws a one-cycle curved line pulsating in an axial direction of the inlet port. A most upstream point of the downstream slot is located at an upstream end portion of impeller blades of the impeller when seen along a direction perpendicular to a rotary shaft of the impeller. According to the centrifugal compressor, it becomes possible to expand its operating range by improving a surging restriction effect brought by more effective casing treatment. | 11-14-2013 |
20140255175 | CENTRIFUGAL COMPRESSOR AND MANUFACTURING METHOD THEREFOR - A centrifugal compressor includes: a volute casing including a first casing and a second casing that are mutually coupled, the first casing including a volute chamber therein and the second casing including an impeller installation space therein; an impeller provided in the impeller installation space so as to be rotatable around a rotation axis; and a vaneless diffuser that has an inlet that communicates with an inside of the second casing and has an outlet that communicates with an inside of the first casing. The vaneless diffuser has a width having a non-axisymmetric distribution in the circumferential direction. | 09-11-2014 |
