AI Technical Summary

Benefits of technology

The invention makes sure that the cleaning liquid is spread evenly across the whole flow-path width, which means that the entire surface of the impeller can be cleaned well and evenly.

Problems solved by technology

In this case, only one cleaning-liquid injection nozzle is provided, and the distance between the cleaning-liquid injection nozzle and the impeller is short, which makes it difficult for the cleaning liquid injected from the cleaning-liquid injection nozzle to spread out sufficiently before reaching the impeller.
Thus, the cleaning liquid is not distributed evenly over the entire region of the flow-path width, and there is a risk that the entire surface of the impeller cannot be cleaned sufficiently and evenly.

Embodiment Construction

[0037]Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It is intended, however, that unless particularly specified, dimensions, materials, shapes, relative positions and the like of components described in the embodiments shall be interpreted as illustrative only and not intended to limit the scope of the present invention.

[0038]For instance, an expression of relative or absolute arrangement such as “in a direction”, “along a direction”, “parallel”, “orthogonal”, “centered”, “concentric” and “coaxial” shall not be construed as indicating only the arrangement in a strict literal sense, but also includes a state where the arrangement is relatively displaced by a tolerance, or by an angle or a distance whereby it is possible to achieve the same function.

[0039]Further, for instance, an expression of a shape such as a rectangular shape or a cylindrical shape shall not be construed as only the geometrically strict shape, but...

Abstract

A centrifugal compressor includes: a main casing having an inlet and an outlet; at least one impeller disposed rotatably inside the main casing; an intake casing connected to the inlet, the intake casing having an intake port on a position spaced away from the inlet in a direction of an axis; a cleaning-liquid injection device capable of being disposed on a side of the intake port inside the intake casing; and a cleaning-liquid supply device for supplying a cleaning liquid to the cleaning-liquid injection device. The cleaning-liquid injection device includes: a pipe capable of being disposed so as to extend along a plane which intersects with the direction of the axis, inside the intake casing; and a plurality of injection holes disposed on the pipe.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a centrifugal compressor.BACKGROUND ART[0002]Patent Document 1 discloses a main casing having an inlet and an outlet, and an impeller disposed rotatably inside the main casing. Such a centrifugal compressor further includes a supply pipe for supplying a cleaning liquid for cleaning the impeller, and a cleaning-liquid injection nozzle for injecting the cleaning liquid supplied from the supply pipe to the surface of the impeller, disposed on the inlet side of the main casing. With such a centrifugal compressor, dust adhering to the surface of the impeller is washed off by the cleaning liquid.CITATION LISTPatent Literature[0003]Patent Document 1: JPH8-338397ASUMMARYProblems to be Solved[0004]The centrifugal compressor disclosed in Patent Document 1 includes a cleaning-liquid injection nozzle disposed in the vicinity of an inlet of a main casing, and a cleaning liquid is injected from the single cleaning-liquid injection nozzle. In ...
