Abstract
The utility model discloses a high-power flameproof submersible pump for mines and relates to the technical field of water pumps. The submersible pump comprises a pump motor which is a flameproof motor, a junction box is arranged at the upper end of the pump motor, a wire outlet is arranged on the left side of the junction box, a wiring board is arranged in the junction box, carrying handles are symmetrically arranged on two sides of the pump motor and hinged to the pump motor, a pump body is connected with the lower end of the pump motor, and the pump body and the pump motor are coaxially connected with each other; and a impeller is arranged in the pump body and fixed at the tail end of a rotation shaft of the pump motor, a water outlet is arranged on the right side of the pump body, a base is connected with the bottom end of the pump body, the base is a filtering cover which is provided with a water inlet, and an external grounding terminal is arranged on the outer side of the filtering cover. The high-power flameproof submersible pump for the mines is simple in structure and reasonable in design, the pump motor of the water pump is manufactured into the flameproof motor (dry motor), the pump motor and the pump body are coaxially arranged into a whole and submerge into the water for operating, and the submersible pump is capable of adapting to complicated environments under the mines and is particularly safe and reliable in usage in the mines having gases and coal dust.
Description
Technical field:
The utility model relates to the pump technology field, relates in particular to a kind of high-power flame-proof type mining diving 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 high-power flame-proof type mining diving 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 high-power flame-proof type mining diving pump; Comprise pump motor, it is characterized in that: said pump motor upper end is provided with terminal box, and the terminal box left side is provided with wire outlet; Be provided with wire board in the terminal box; Said pump motor both sides are provided with carrying handle, and 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, and the filter cap arranged outside has external ground.
Said carrying handle is provided with in the pump motor bilateral symmetry, and carrying handle and pump motor are hinged.
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 high-power flame-proof type mining diving pump comprises pump motor 3; Pump motor 3 is an explosion separation motor, and pump motor 3 upper ends are provided with terminal box 5, and terminal box 5 left sides are provided with wire outlet 7; Be provided with wire board 6 in the terminal box 5, pump motor 3 both sides are provided with carrying handle 4, and carrying handle 4 is in pump motor 3 bilateral symmetry settings; Carrying handle 4 is hinged with pump motor 3, and pump motor 3 lower ends connect the pump housing 10, and the pump housing 10 is coaxial with pump motor 3; In the said pump housing 10 impeller 8 is set, impeller 8 is fixed on the end of pump motor rotating shaft, and the pump housing 10 right sides set out the mouth of a river 2, and the pump housing 10 bottoms connect base 9, and base 9 is for being provided with the filter cap of water intake, and the filter cap arranged outside has external ground 1.
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.
