Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the electrochemical protection water pump includes the He of water pump body structure 10 processed by ferrous material
The protection metal derby 20 processed by aluminium based material or zinc series materials.It should be noted that the ferrous material is included but not
Be limited to one kind in stainless steel, cast iron and cast steel or at least two combinations, the aluminium based material include but is not limited to aluminium alloy and/
Or metallic aluminium, the zinc series materials include but is not limited to kirsite and/or metallic zinc.
The water pump body structure 10 includes inducer 11, spiral case 12 and the outlet section set gradually along liquid flow direction
13, and the impeller 14 in the spiral case 12.Moreover, the side wall of the inducer 11 is provided with through hole 111, the through hole 111
It is connected with the liquid flow space in the water pump body structure 10.
The protection metal derby 20 is embedded in the water pump body structure 10 and is exposed to the structure of water pump body 10
Outside.And it is described protection metal derby 20 run through the water pump body structure 10 side wall, and with the water pump body structure 10
Conveying liquid contact.
Specifically, in the present embodiment, the protection metal derby 20 is embedded in the through hole 111 of the inducer 11, from
And cause the protection metal derby 20 through the side wall of the inducer 11 and directly contacted with the conveying liquid.Preferably,
The protection metal derby 20 is interference fitted with the inducer 11.
