Pump using waste tire

Abstract

Disclosed herein is a pump using a waste tire, capable of providing high abrasion-resistance and corrosion-resistance, and ensuring easy manufacture and maintenance, in addition to the prevention of a water hammer and rupture due to cold. In the pump of the present invention, a casing main body ( 110 ) is made of a waste tire. An inlet port unit ( 130 ) is installed at a first opening provided at a side of the waste tire, and a housing ( 120 ) is installed at a second opening provided at another side of the waste tire in such a way that an impeller ( 150 ) is set inside the casing main body ( 110 ). An outlet port unit ( 140 ) is installed at predetermined portion of the waste tire, thus acting as an outlet port of the casing main body. A sub-vane ( 152 ) made of a waste tire is removably mounted to a main vane ( 151 ) of the impeller.

1 . A pump using a waste tire, the pump comprising: 
 a housing provided with an impeller, and    a casing main body having an inlet port and an outlet port, wherein said casing main body is made of a waste tire while keeping an original shape of the waste tire, with an inlet port unit being installed at a first opening which is provided at a side of the waste tire, thus functioning as the inlet port of the casing main body, and the housing being installed at a second opening provided at another side of the waste tire opposite to the first opening in such a way that the impeller is set inside the casing main body, and an outlet port unit being installed at a predetermined portion of the waste tire to function as the outlet port of the casing main body.    
   
   
       2 . The pump according to  claim 1 , wherein a sub-vane made of a waste tire is removably mounted to a main vane of the impeller.  
   
   
       3 . The pump according to  claim 1 , wherein liners used for easily replacing the waste tire of the casing main body with another waste tire are installed on inner surfaces of the housing and the inlet port unit, respectively, which are provided on both sides of the casing main body made of the waste tire.  
   
   
       4 . The pump according to  claim 1 , wherein two U-shaped connecting rings are fitted over two portions of the casing main body in radial directions, 0 respectively, in such a way that both ends of each of the connecting rings are fastened to the housing and the inlet port unit, respectively.  
   
   
       5 . The pump according to  claim 1 , wherein the housing and the inlet port unit are fastened to liners by means of fastening pieces.
