Abstract
The utility model discloses a mining flame-proof submersible pump and relates to the technical field of water pumps. The mining flame-proof submersible pump comprises a pump motor. The pump motor is a flame-proof motor; the upper end of the pump motor is provided with a junction box; the left side of the junction box is provided with a wire outlet; the upper end of the junction box is provided with a carrying handle; the interior of the junction box is provided with a wiring board; the lower end of the pump motor is connected with a pump body; the pump body and the pump motor are coaxial; the interior of the pump body is provided with an impeller; the impeller is fixedly arranged at the tail end of the rotating shaft of the pump motor; the right side of the pump body is provided with a water outlet; the bottom end of the pump body is connected with a base; and the base is a filter mask provided with a water inlet. The mining flame-proof submersible pump disclosed by the utility model is simple in structure and reasonable in design. The pump motor of the water pump is manufactured into the flame-proof motor, and the flame-proof motor and the pump body are coaxially integrated into a whole to submerge to run, therefore, the complex environment under a mine can be adapted. The mining flame-proof submersible pump is especially safe and reliable when being used under the mine containing gas and dust.
Description
Technical field:
The utility model relates to the pump technology field, relates in particular to a kind of mining flame-proof type submersible pump.
Background technique:
Water under the mine is mainly from Atmospheric precipitation, surface water, aquifer water, tomography water and old empty ponding, and in the mine that uses hydraulic flushing method, hydraulic mining method exploitation, mine water also comprises some waste water that pour in mine.Swallet has been dissolved many mineral substance in the process of flowing of down-hole, also contain simultaneously the impurity such as ickings, quicksand of some.Therefore, the general clear water of mine water proportion is big, when 15 ℃ of water temperatures, is 1015～1025kg/m
3The impurity that swallet contains is a lot, and the particle of state of suspension is wherein arranged, easy abrasion water pump part.Also contain free acid in the swallet, its content shows the acid intensity of water, and acidity is big more, and is just big more to water pump and corrosion of pipe effect.Generally acid degree is described by pH value in the water.Existing nowadays general de-water is to adopt common submersible pump to carry out the drainage works under the mine.Yet along with the development of China's mining industry, increasingly high to the method requirement of draining, common submersible pump has satisfied not people's requirement.
The model utility content:
The utility model technical problem to be solved is to overcome the defective of existing technology; A kind of mining flame-proof type submersible pump is provided; Being applicable to has methane and coal dust explosion hazard property occasion under the coal mine, contain the sewage liquid of non-corrosive solid matters such as cinder, silt in the fed sheet of a media.
The utility model technical problem to be solved adopts following technological scheme to realize.
A kind of mining flame-proof type submersible pump comprises pump motor, it is characterized in that: said pump motor upper end is provided with terminal box; The terminal box left side is provided with wire outlet, and the terminal box upper end is provided with carrying handle, is provided with wire board in the terminal box; The pump motor lower end connects the pump housing, and the pump housing is coaxial with pump motor; In the said pump housing impeller is set, pump housing right side sets out the mouth of a river, and pump housing bottom connects base.
Said pump motor is an explosion separation motor.
Said impeller is fixed on the end of pump motor rotating shaft.
Said base is the filter cap that is provided with water intake.
The utility model is simple in structure, and is reasonable in design, and the pump motor of water pump processes that flame-proof type (dry type) and the pump housing are coaxial can to adapt to the complex environment under the mine for the one operation that pulls the plug, and under the mine that contains gas and coal dust, uses, and is especially safe and reliable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of mining flame-proof type submersible pump comprises pump motor 1; Pump motor 1 is an explosion separation motor, and pump motor 1 upper end is provided with terminal box 3, and terminal box 3 left sides are provided with wire outlet 2; Terminal box 3 upper ends are provided with carrying handle 4; Be provided with wire board 9 in the terminal box 3, pump motor 1 lower end connects the pump housing 7, and the pump housing 7 is coaxial with pump motor 1; In the said pump housing 7 impeller 8 is set, impeller 8 is fixed on the end of pump motor rotating shaft, and the pump housing 7 right sides set out the mouth of a river 5, and the pump housing 7 bottoms connect base 6, and base 6 is for being provided with the filter cap of water intake.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
