Abstract
The utility model provides a flame-proof type submerged sewage electric pump for mining, which belongs to the technical filed of a submerged sewage electric pump. The pump comprises an upper bearing seat, a motor shell body, a rotor, a lower bearing seat, a sealing chamber, a turbine scroll, an impeller and a base. The upper end part of the base is fixedly connected with the turbine scroll, the impeller is arranged in the turbine scroll, the sealing chamber is arranged at the upper end part of the turbine scroll, the motor shell body is arranged at the upper surface of the sealing chamber, and the upper bearing seat and the lower bearing seat used for fixing the rotor of the motor are respectively arranged at the upper and lower parts in the motor shell body, so as to ensure that liquid in the pump cannot flow upwards to damage the lower bearing seat and the upper bearing seat under the rotor. Compared with the prior art, the flame-proof type submerged sewage electric pump has the advantages of compact design, small volume, light weight, long service life, strong dirt removing capability, stable running and the like. As the special sealing design of the sealing chamber is adopted, the overlong sealing property solves the disadvantages of the old-style submerged sewage electric pump that the sealing life is short and the motor can be burnt down if water enters, so as to achieve the stable performances of reliable sealing and good safety stability.
Description
(1) technical field
The utility model relates to a kind of immersed sewage electric pump, specifically a kind of flame-proof mine immersed sewage electric pump.
(2) background technique
The immersed sewage electric pump is applicable to industrial departments such as colliery, metallurgy, electric power, building materials, has gas and inflammable and explosive place, carries to contain the mixed sewage of SSs such as silt, cinder, fiber or certain corrosive liquid is arranged.Pump should have flame proof, wear-resisting, corrosion-resistant function.
Protections such as overheated, the leak of liquid of immersed sewage electric pump, overload, wearing and tearing at present both at home and abroad all realize distant control by lead-in wire, but do not meet the reality of mining mobile operational process, use inconveniently, use on the ore deposit to be difficult to acceptance.Be provided with the mine pump of filter screen for pump inlet, carry that particle is less, concentration is not very high mine pump, generally all adopt blade impellers, can adopt the impeller of semi-open type or enclosed construction, wherein the efficient of enclosed construction impeller is higher slightly; Also have the small-sized mining diving pump of part to adopt flow channel type blade wheel structure, its passing capacity stronger, but impeller lays particular stress on, efficient is lower than the enclosed construction impeller slightly.
(3) summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of long service life, safe and reliable flame-proof mine immersed sewage electric pump are provided.
The technological scheme that its technical problem that solves the utility model adopts is:
Flame-proof mine immersed sewage electric pump, comprise upper bearing bracket, electric machine casing, rotor, step, closed chamber, volute, impeller, base, fixedly connected with volute in the upper end portion of base, be provided with impeller in the volute, the upper end portion of volute is provided with closed chamber, the upper surface of closed chamber is provided with electric machine casing, position up and down in the electric machine casing is respectively arranged with the upper bearing bracket and the step of fixed electrical machinery rotor, to guarantee that liquid can not uply cause damage to subtrochanteric step and upper bearing bracket in the water pump.
Flame-proof mine immersed sewage electric pump of the present utility model compared with prior art, advantage such as the beneficial effect that is produced is, this pump is compact to design, and volume is little, in light weight, long service life, pollution discharge capability are strong, operate steadily.
(4) description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, the cable gland, 2, outlet box, 3, upper bearing bracket, 4, electric machine casing, 5, rotor, 6, step, 7, closed chamber, 8, volute, 9, impeller, 10, base.
(5) embodiment
Below in conjunction with explaining below 1 pair of flame-proof mine immersed sewage electric pump work of the present utility model of accompanying drawing.
As shown in Figure 1, flame-proof mine immersed sewage electric pump of the present utility model, its structure comprises cable gland 1, outlet box 2, upper bearing bracket 3, electric machine casing 4, rotor 5, step 6, closed chamber 7, volute 8, impeller 9, base 10, fixedly connected with volute 8 in the upper end portion of base 10, be provided with impeller 9 in the volute 8, the upper end portion of volute 8 is provided with closed chamber 7, the upper surface of closed chamber 7 is provided with electric machine casing 4, position up and down in the electric machine casing 4 is respectively arranged with the upper bearing bracket 3 and the step 6 of fixed electrical machinery rotor 5, to guarantee that liquid can not uply cause damage to step under the rotor 56 and upper bearing bracket 3 in the water pump.
Its processing and fabricating of flame-proof mine immersed sewage electric pump of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
