Problems solved by technology

In this case, since there is only one washer liquid spray nozzle and the distance from the washer liquid spray nozzle to the impeller is short, the washer liquid sprayed from the washer liquid spray nozzle cannot be sufficiently diffused before reaching the impeller.
Therefore, the cleaning liquid cannot spread evenly over the entire width of the flow path, and it may not be possible to clean the surface of the impeller as a whole in a balanced and sufficient manner.

Embodiment Construction

[0067] Hereinafter, some embodiments of the present invention will be described with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of components described in the embodiments or shown in the drawings do not limit the scope of the present invention thereto, but are merely illustrative examples.

[0068] For example, expressions such as "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "concentric" or "coaxial" indicating relative or absolute configurations not only strictly express such The configuration also means a state of relative displacement with a tolerance or an angle or a distance to the extent that the same function can be obtained.

[0069] In addition, for example, expressions such as quadrangular shape, cylindrical shape, etc., not only mean quadrangular shape, cylindrical shape, etc. in a geometrically precise sense, but also include concave-convex parts and chamfe...

Abstract

This centrifugal compressor is provided with: a main casing which has an inlet and an outlet; at least one impeller which is rotatably arranged inside of the main casing; a suction casing which is connected to the aforementioned inlet and which has a suction port in a position spaced away from the inlet in the axial direction; a cleaning solution injection device which can be arranged to the side of the suction port inside of the suction casing; and a cleaning solution supply device which supplies a cleaning solution to the cleaning solution injection device. The cleaning solution injection device comprises, inside of the suction casing, a pipe which can be arranged so as to extend along a plane intersecting the axial direction, and multiple injection holes provided in said pipe.

Description

technical field [0001] This invention relates to centrifugal compressors. Background technique [0002] Patent Document 1 discloses a centrifugal compressor including a main casing having an inlet and an outlet, and an impeller rotatably arranged inside the main casing. This centrifugal compressor includes a supply pipe for supplying cleaning liquid to the impeller as a cleaning object, and a cleaning liquid spraying nozzle provided on the inlet side of the main casing to spray the cleaning liquid supplied from the supply pipe onto the surface of the impeller. According to this centrifugal compressor, dust adhering to the surface of the impeller is washed away by the cleaning liquid. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Application Laid-Open No. 8-338397 [0006] Summary of the invention [0007] The technical problem to be solved by the invention [0008] In the centrifugal compressor disclosed in Patent D...
