On a kind of impeller of the present utility model, have the mining submersible electric pump of equalizing orifice compared with prior art, the beneficial effect producing is:
The utility model is used has simplified water pump structure with the impeller of equalizing orifice, balancing axial thrust more effectively, expanded the Applicable scope of water pump, extended the working life of water pump, adopt rich chromium cast iron material to make it have good wear-resisting property, the hydraulic performance and the efficiency that have improved water pump, met user's actual demand.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The structural front view that accompanying drawing 2 is beaten equalizing orifice for impeller.
In figure: 1. cable, 2. wire outlet box cover, 3. upper bearing bracket, 4. bearing, 5. housing, 6. have winding stator core, 7. rotor, 8. shell, 9. step, 10. bearing, 11. mechanical seals, 12. sealing chamber caps, 13. spiral cases, 14. impellers, 141. equalizing orifices, 15. pump covers, 16. bases.
Embodiment
Below doing below in conjunction with 1,2 pairs of the utility model of accompanying drawing, specifically describe in detail.
By reference to the accompanying drawings 1,2, the utility model provides the mining submersible electric pump that has equalizing orifice on a kind of impeller, it comprises electric machine assembly and the pump assembly being arranged in up and down on base 16, described electric machine assembly includes winding stator core 6, rotor 7, upper bearing bracket 3 and step 9, and described pump assembly comprises pump shaft, the pump housing, impeller 14.Described base 16 upwards connects pump cover 15, shell 8, wire outlet box cover 2 successively by bolt, described wire outlet box cover 2 also with upper bearing bracket 3, housing 5, step 9, spiral case 13, sealing chamber cap 12 from top to bottom bolt be connected, between described step 9 and sealing chamber cap 12, be provided with mechanical seal 11, described impeller 14 is fixed on rotor shaft by the shaft shoulder, key, locking nut, impeller 14 suction inlets coordinate with pump cover 15 endoporus, at impeller 14 back sides, beat equalizing orifice 141.Described equalizing orifice 141 is perpendicular to the through hole at the impeller back side, and number is 4-8, and evenly annular is distributed on impeller 14 back sides.Described impeller 14 adopts rich chromium cast iron material.
