Abstract
The utility model discloses an upper motor lower pump type mining submersible multistage electric pump comprising a submersible pump and a submersible motor connected with the submersible pump. The submersible motor is disposed above the submersible pump. A water inlet port of the submersible pump is disposed in a bottom end of the pump, and a water outlet pump of the submersible pump is provided with a water guide cover. The water guide cover is sleeved on the outside of the submersible pump, and a water outlet port is disposed in the top of the water guide cover. The utility model adopts the upper motor lower pump type structure, thereby the on-site environment water level can be reduced, the excavation workload of a flooding well can be reduced, and at the same time, the water from the water pump flows through the housing of the motor, and can take away a large amount of heat energy to reduce the temperature rise of the motor, and the service lifetime of the motor can be prolonged.
Description
Technical field
The utility model relates to a kind of mining pump series products, mainly is the multistage electric pump of the mining diving of a kind of up-machine down-pump type.
Background technique
Showing the present domestic multistage electric pump structure of mining diving is that motor is descending, and water pump is promptly gone up machine formula structure under the pump on the top of motor; Motor at whole unit bottom, water outlet connects lifting pipe topmost; Thereby when unit is worked, sufficiently high depth of immersion must be arranged, increased the cutting depth of whole waterflooding well, in the low place of some environment water levels; The depth of immersion of unit does not reach the needs of product, can't satisfy the requirement of operating mode; Motor is in the bottom of water pump simultaneously, and the motor outside is an Environmental Water, and flow velocity is minimum, can only take away the part heat that motor produces.
The model utility content
The utility model technical problem to be solved provides the multistage electric pump of the mining diving of a kind of up-machine down-pump type; It adopts the up-machine down-pump type structure, can reduce on-the-spot environment water level, reduces the excavation workload of waterflooding well; The water pump water outlet shell of motor of flowing through simultaneously; Can take away a large amount of heats that motor produces rapidly, reduce the temperature rise of motor, prolong the working life of motor.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
The multistage electric pump of the mining diving of a kind of up-machine down-pump type; Include submersible pump, the submersible motor that is connected with submersible pump is characterized in that: described submersible motor is positioned at the top of submersible pump; On the said submersible pump water intake be positioned at the lowermost end of pump; The water outlet place of said submersible pump is equipped with water guide cover, and described water guide cover is enclosed within outside the submersible motor, and the top of said water guide cover is provided with water outlet.
The utility model adopts motor on top, and water pump is in the bottom, i.e. up-machine down-pump type structure, make whole water pump water intake at unit bottom, very low for the requirement of site environment water level, only need flood water intake, electric pump gets final product work; Can reduce on-the-spot environment water level, depth of immersion is little simultaneously, reduces the excavation workload of waterflooding well, has practiced thrift construction cost.Simultaneously water intake unit below, reduced the cavitation of water pump.
Motor is on the top of water pump, and from must the flow through shell of motor of the water of pump outlet, flow velocity is big, can take away a large amount of heats that motor produces rapidly, reduces the temperature rise of motor, improves the Environmental Conditions of motor, prolongs the working life of motor.
After submersible pump and submersible motor assemble completion respectively, dock.When using at the scene, connect outside installation system more separately, simple in structure, easy to operate.
The utility model has the advantages that:
The utility model adopts the up-machine down-pump type structure, can reduce on-the-spot environment water level, reduces the excavation workload of waterflooding well; The water pump water outlet shell of motor of flowing through simultaneously; Can take away a large amount of heats that motor produces, reduce the temperature rise of motor, prolong the working life of motor.
