Abstract
An anticorrosion structure of a water pump impeller housing comprises an impeller housing, wherein the internal wall of the impeller housing is provided with a stainless steel lining, a plug welding through-hole is distributed on the impeller housing, and the internal wall of the impeller housing is connected with a stainless steel lining plug weld in a welding mode through the plug welding through-hole and solders. The anticorrosion structure plays a good role of preventing corrosion, further lowers consumption of stainless steel materials and cost of manufacture, and is also convenient for processing. The plug welding through-hole is distributed on the impeller housing, the stainless steel lining is welded with a plug weld of the impeller housing internal wall through the plug welding through-hole, and the anticorrosion structure of the water pump impeller housing can effectively achieve the tight connection between the impeller housing and the stainless steel lining.
Description
Technical field
The utility model relates to water pump, is specifically related to the anti-corrosion structure of pump shell.
Background technique
The impeller housing of water pump since be subjected to that hydraulic shock power acts on repeatedly for a long time and liquid in the chemical corrosion effect of trace dissolved oxygen, spot can appear after operation a period of time with crackle even become spongy damage, serious cavitation phenomenons takes place.For preventing the generation of water pump vane shell cavitation phenomenons, the manufacturer that has brushes anti-corrosion material at the impeller housing inner chamber, to reach the corrosion-resistant effect, but anticorrosion with coat poor performance, and not anti-washing away, coating easily comes off, thereby the life-span is very short, can't really satisfy requirement for anticorrosion effectively.The manufacturer that has adopts whole stainless steel material to make impeller housing, to reach the corrosion-resistant effect, but impeller housing only has surface of internal cavity contact corrosion medium, its outer surface is under the atmosphere environment of normal temperature and pressure, there is no special requirement for anticorrosion, adopt whole stainless steel material, cost an arm and a leg, the product price ratio is poor.
The content of model utility
At the above-mentioned shortcoming of existing corrosion-proof type water pump vane shell, the claimant has carried out improving research, and the anticorrosion structure of another kind of water pump vane shell is provided, and can reach antiseptic effect, and is with low cost again.
The technical solution of the utility model is as follows:
A kind of anticorrosion structure of water pump vane shell, comprise impeller housing, the inner wall device of described impeller housing has stainless steel inner lining, is distributed with the plug welding through hole on the impeller housing, and the inwall of impeller housing is welded to connect by plug welding through hole and scolder and described stainless steel inner lining plug welding.The internal face of described stainless steel inner lining is an arc shaped surface.
Useful technique effect of the present utility model is:
The utility model is provided with stainless steel inner lining by the inwall at impeller housing, and impeller housing and stainless steel inner lining plug welding are welded to connect, and have both played good antisepsis, have reduced the consumption of stainless steel material again, reduces manufacture cost, and processing is also convenient.Distribution plug welding through hole on impeller housing, stainless steel inner lining is connected with the plug welding of impeller housing inwall by the plug welding through hole, realizes that effectively impeller housing is connected with the tight of stainless steel inner lining, reduces the gap of inner surface of contact, guarantees the reliability that connects.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 shows structure of the present utility model.As shown in Figure 1, the utility model comprises impeller housing 1, the inner chamber of impeller housing 1 leaves the cavity of placing stainless steel inner lining 2, stainless steel inner lining 2 is arranged in this cavity, on the wall of impeller housing 1, arrange plug welding through holes 3 in being drilled with two with the position of stainless steel inner lining 2 welding, the inwall of impeller housing 1 is welded to connect by plug welding through hole 3 and stainless steel inner lining 2 plug weldings, and it is firm to fit.
Concrete formation process is as follows: at first stainless steel inner lining 2 is rolled into tubular by lathe, then stainless steel inner lining 2 is put into the groove of impeller housing 1 inwall, and put on right position; Fill up scolder in the plug welding through hole 3 on impeller housing 1 wall and freeze, by internal stress stainless steel inner lining 2 is strained after the cooling, be close on the inwall of impeller housing 1, make impeller housing 1 internal face is very little with the gap of stainless steel inner lining 2, the assurance sealing.After stainless steel inner lining 2 plug weldings are fixing, also will be by the port of impeller housing 1, freezed in the gap between the inwall of the gap between the inwall of the two ends of liner and impeller housing 1 and jointing and impeller housing 1, freezed fully in described gap 100%.By numerical control machine tool the internal face of stainless steel inner lining 2 is processed as arc shaped surface then, so that consistent with the termination shape of impeller blade.Zone on the dotted line of Fig. 1 is a truncated section.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that those skilled in the art under the prerequisite that does not break away from spirit of the present utility model and design, can make other improvement and variation.
Claims (2)
1. the anticorrosion structure of a water pump vane shell, comprise impeller housing, it is characterized in that: the inner wall device of described impeller housing has stainless steel inner lining, is distributed with the plug welding through hole on the impeller housing, and the inwall of impeller housing is welded to connect by plug welding through hole and scolder and described stainless steel inner lining plug welding.
