The present invention relates to a device with a changeable intake vane for an axial and mixed flow pump, capable of enhancing efficiency by guiding a fluid for a smooth transfer by changing an intake vane at an optimal angle when the fluid is taken in a simple mechanical structure, and also returning the intake vane to an original state when the intake of the fluid stops. The present invention, including multiple intake vanes (200) installed in an intake casing (100) of an axial and mixed flow pump (10), comprises: multiple axial holes (110) formed in the intake casing (100); a connection shaft (210) protruding outward from the intake vanes (200), and installed in the axial holes (110) to be rotatable; a support shaft (220) integrated with the connection shaft (210) to protrude outward from the intake casing (100); a housing (300) including an axial hole and inserted into the support shaft (220) to be fixed outside the intake case (100); a bearing (400) installed inside the housing (300) to support the support shaft (220) to be rotatable; a cover (500) fixed outside the housing (300) to protect the bearing (400); and a spring (600) applying elasticity to the intake vanes (200) to elastically rotate the intake vanes (200) during operation and returning the vanes to an original state during interruption. |
