Description
Technical field
The utility model relates to a kind of impeller of shell pump, especially shell pump abrasion proof impeller.
Background technique
Shell pump due to work condition environment severe, the flow passage components abrasion condition of pump is very serious, and the wearing and tearing of its core component impeller are more outstanding, under normal circumstances, impeller general working life of shell pump, less than one week, needs frequently to change, both affect working efficiency, increase user cost again.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided shell pump abrasion proof impeller, impeller is integral type, the high-abrasive material of surface coverage one deck polyurethane elastomer type, increase the wear-resisting property of impeller greatly, effectively improve the working life of impeller.
For achieving the above object, the technical solution of the utility model is: shell pump abrasion proof impeller, comprise the impeller plate, blade one, blade two, blade three, coating, the described impeller plate is circular, the axle to downward-extension is established in centre, mounting hole is established in described axle, keyway is established in described dress hole, the uniform blade one above of the impeller plate, blade two, blade three, described blade one, blade two, blade three root circle is identical with axle external diameter, head is identical with the external diameter of the impeller plate, head thickness is greater than root thickness, and in clockwise direction external radiation shape, if inside Inner arc, peripheral hardware external arc, blade one, blade two, blade three from outside to inside 2/3rds places starts to establish downward oblique angle, with impeller plate flat face bottom described oblique angle, the described impeller plate, blade one, blade two, blade three and axle surface are all coated with coating.
Further setting, the described impeller plate and axle junction surface establish step.
Further setting, the described impeller plate is all laid three screws.
Further setting, described coating is the high-abrasive material of polyurethane elastomer type.
The beneficial effects of the utility model are: the high-abrasive material of surperficial full coverage polyurethane elastomer type, are beneficial to the wear resistance improving impeller, increase the service life; Use middle period wheel as a beaer, what wear and tear or come off is the coating that appearance covers, and the coating of carrying out be convenient to impeller repeats covers utilization, saves metallic material, saves user cost.
Accompanying drawing explanation
