Abstract
A rubber pump is disclosed by the utility model and is characterized in that the utility model is provided with a metal impeller framework 1 and a rubber layer 3 melted on surface of the metal framework. The rubber pump provided by the rubber pump is simple in structure, low in costs of manufacture, effectively makes use of corrosion resistance and wearability of rubber to improve corrosion resistance and wearability of the pump and increase service life of the pump with ensured rigidity of the pump body.
Description
Technical field
The utility model relates to a kind of water pump vane, relate in particular to a kind ofly be applied to dig up mine, the water pump vane of ore dressing industry.
Background technique
The impeller that is applied to water pump at present all is to adopt metallic material to cast, though can satisfy its rigidity requirement with the metallic material casting impeller, but as mining, ore dressing already in the strong industry easy to wear of some corrosivity, in use impeller shortens operating life because of the burn into wearing and tearing easily, need frequent replacing thus, influence working efficiency, increase cost of production, though some impeller adopts the anticorrosive wear-resistant metallic material to cast, but its preparation process requires high, fabricating cost is big, can only use in the special industry of minority, can not satisfy marketing and use.
Summary of the invention
The purpose of this utility model provides a kind of rubber impeller, and it is to utilize the anticorrosive wear-resistant characteristic of rubber to increase the operating life of impeller effectively.
In order to achieve the above object, the technological scheme that the utility model adopted is: be provided with an impeller framework of being made by metallic material, guarantee the rigidity of impeller with this, the molten stream of outer surface one deck rubber layer in impeller framework, rubber layer can prevent when work fluid to the corrosion and the wearing and tearing of impeller framework, thereby increase the corrosion resistance and the wear resistance of impeller.
In order to increase the adhesion of rubber layer on impeller framework, on impeller framework, be provided with attachment hole, this attachment hole can allow rubber can pass attachment hole when molten stream and link together, and guarantees that in use rubber layer does not come off.
Rubber blade wheel structure provided by the utility model is simple, and fabricating cost is low, and it effectively utilizes the corrosion resistance and the wear resistance of rubber, has improved the corrosion resistance and the wear resistance of impeller under the prerequisite that guarantees the impeller rigidity, has prolonged the working life of impeller.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model embodiment rubber impeller.
Embodiment
Impeller framework 1 is made by metallic material, guarantee the rigidity of impeller with this, at the molten stream of the outer surface of impeller framework one deck rubber layer 2, rubber layer 2 can prevent when work fluid to the corrosion and the wearing and tearing of impeller framework 1, thereby increases the corrosion resistance and the wear resistance of impeller.
In order to increase the adhesion of rubber layer 2 on impeller framework 1, impeller framework is provided with attachment hole 3, and this attachment hole can allow rubber can pass attachment hole when molten stream and link together, and guarantees that in use rubber layer 2 does not come off.
