Spiral fluted wheel for a pump

Abstract

A spiral fluted wheel ( 10 ) for a pump is composed of a first plate ( 11 ), a second plate ( 12 ) corresponding to the first plate ( 11 ), and a plurality of spiral blades sandwiched between the first plate ( 11 ) and the second plate ( 12 ). The plurality of spiral blades are combined easily and each has a large welding area corresponding to the first plate ( 11 ) and the second plate ( 12 ) so as to make the wheel have excellent endurance and precision in structure.

What is claimed is:  
     
         1 . A spiral fluted wheel for a pump adapted to be secured on a rotating device, and the spiral fluted wheel ( 10 ) comprising: 
 a first plate ( 11 ) having a lock hole ( 110 ) defined in a center of the first plate ( 11 ), and a periphery defining the lock hole ( 110 ) adapted to be firmly secured on a rotating device;    a second plate ( 12 ) corresponding to the first plate ( 11 ) and having an inlet aperture ( 120 ) defined in a center of the second plate ( 12 ) for entry of water into the spiral fluted wheel ( 10 ); and    multiple spiral blades ( 20 ) sandwiched between the first plate ( 11 ) and the second plate ( 12 ), each spiral blade ( 20 ) having a spiral channel ( 21 ) defined therein and forming a sub-channel ( 25 ) with an adjacent spiral blade ( 20 ) whereby in operation the spiral fluted wheel is driven to rotate by the rotating device and water travels into the spiral fluted wheel via the inlet aperture and is centrifugally driven outwardly along the spiral channel and sub channel.    
     
     
         2 . The spiral fluted wheel for a pump as claimed in  claim 1 , wherein each spiral blade has two wedges ( 23 ) extending respectively outwardly from the spiral blade ( 20 ), each wedge ( 23 ) complemented with other wedge ( 23 ) of adjacent spiral blades so as to form the sub-channel ( 25 ).
