The submersible electric pump comprises a motor assembly and a pump assembly, wherein the motor assembly and the pump assembly are arranged on a base in an up-down mode, the upper portion of the base is fixedly connected to the bottom of an outer shell through a bolt, the motor assembly comprises a winding stator iron core, a rotor, an upper bearing base and a lower bearing base, the parts are sequentially connected with the inside of the outer shell through bolts, the pump assembly comprises a pump shaft, a pump body and an impeller, the impeller is in key connection with the pump shaft, a mechanical seal is arranged between a volute and a sealing chamber cover, an inner spigot of the volute and an outer spigot of the lower bearing base are matched and connected through an outer hexagon screw, and the volute and a pump cover are welded together and are connected with the base through hexagon socket screws. Compared with the prior art, the submersible electric pump reduces interstage leakage, is simple in structure and low in production cost, has good impact-resistant performance and can prolong service life and meet practical needs of users.
Description
Technical field
The utility model relates to a kind of Submerged Motor Pumps, specifically a kind of mining submersible electric pump.
Background technique
At present, there are a lot of problems in mining submersible electric pump on project organization, such as the structure problem of spiral case.Generally, in mining submersible electric pump, spiral case and pump cover are two independently component, they are connected with base by bolt, and this makes the complex structure of water pump, have virtually increased cost of production, also easily cause inter-stage to reveal, reduce the hydraulic efficiency of mining submersible electric pump.On the other hand; in the normally used environment of mining submersible electric pump; the medium of user's discharge is the sewage that contains large solid particle mostly; large solid particle in these sewage can constantly impact the spiral case in mining submersible electric pump; the material of spiral case is generally spheroidal graphite cast iron; and the intensity of spheroidal graphite cast iron is not high, just often there is the situation of spiral case fracture in this, thus the working life of seriously reducing water pump.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, provides a kind of and can more effectively simplify water pump structure, reduces production costs, improves spiral case anti-impact force, increases the water pump mining submersible electric pump in working life.
The utility model solves the technological scheme that its technical problem adopts:
A kind of mining submersible electric pump, comprise the electric machine assembly and the pump assembly that are arranged in up and down on base, the top of described base is bolted is fixed on outer casing bottom, described electric machine assembly includes winding stator core, rotor and upper, step, and with bolt, be connected in enclosure successively between each parts, described pump assembly comprises pump shaft, the pump housing, impeller, described impeller key is connected on pump shaft, described spiral case has mechanical seal with sealing chamber cap place, the inner stopper of spiral case coordinates with step outer stopper, by outer-hexagonal bolt, couple together, described spiral case and pump cover cast solid, and couple together by socket head screw and base.
The material of described spiral case is alloyed steel.
Compared with prior art, the beneficial effect producing is a kind of mining submersible electric pump of the present utility model:
The utility model is cast as one spiral case and pump cover, has reduced inter-stage leakage, has improved the hydraulic efficiency of water pump, simplifies the structure simultaneously, has reduced cost of production cost of production; Adopt alloyed steel material to make it have good shock resistance, can extend the working life of mining submersible electric pump, meet user's actual demand.
Accompanying drawing explanation

Accompanying drawing 2 is the structural front view that spiral case and pump cover are cast as one.
In figure: 1. cable, 2. outlet box, 3. upper bearing bracket, 4. bearing, 5. housing, 6. have winding stator core, 7. rotor, 8. bearing, 9. step, 10. sealing chamber cap, 11. mechanical seals, 12. spiral cases, 13. impellers, 14. 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, a kind of mining submersible electric pump of the present utility model, the top of described base 14 is bolted is fixed on outer casing bottom, described electric machine assembly includes winding stator core 6, rotor 7, upper bearing bracket 3 and step 9, and with bolt, be connected in enclosure successively between each parts, described pump assembly comprises pump shaft, the pump housing, impeller 13, described impeller 13 keys are connected on pump shaft, described spiral case 12 has mechanical seal 11 with closed chamber 10 places, the inner stopper of spiral case 12 coordinates with step 9 outer stoppers, by outer-hexagonal bolt, couple together, described spiral case 12 and pump cover cast solid, and couple together by socket head screw and base 14, this linkage structure of spiral case has reduced inter-stage leakage, simplify the structure, reduced cost of production, guaranteed that spiral case is at the operating relative position of mining submersible electric pump simultaneously, met the actual demand of water pump.The material of spiral case is alloyed steel.
Its processing and fabricating of a kind of mining submersible electric pump of the present utility model is simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characteristics described in specification, be the known technology of those skilled in the art.
