Description
Technical field
The utility model belongs to pump technology field, is related to a kind of deep well pump, more particularly to a kind of oil immersed type deep well pump bottom
Seat.
Background technology
Deep well pump is that motor and water pump direct-connected integrated pull the plug the water lift equipment of work, with simple structure, unit effect
Rate is high, and noise is small, safe and reliable to operation, advantage convenient to install and maintain.Must be hydraulically full in suction line and pump before turn on pump, open
Impeller rotates at a high speed after pump, and liquid therein rotates, under the influence of centrifugal force, flies away from impeller and outwards penetrate together with blade
Go out, the liquid of the injection speed in pump case diffuser casing is gradually slack-off, and pressure gradually increases, then flowed out from pump discharge discharge pipe,
Both the vacuum low-pressure area without liquid without air, liquid pool are now formed because liquid is thrown toward surrounding at blade center
In liquid flow into pump in the presence of the atmospheric pressure of pond face.
The characteristics of oil immersed type deep well pump is that motor internal is full of machinery oil, and fluid transfers out rapidly the heat of motor internal
Come, cooling effect more preferably, makes the temperature rise of motor significantly decline, thus increased the overload capacity of deep well pump.In addition, oil immersed type
The bearing of deep well pump works in being immersed in fluid, and lubrication is guaranteed with cooling, so deep-well of the bearing life than other patterns
Pump will be grown.The motor of current oil immersed type deep well pump is all mounted to pump housing bottom, caves inward to form limiting stand by the pump housing
Rank is fixed, thus motor be more easy to biasing it is not high with the axiality of impeller, deep well pump in use easily vibrations run
It is unstable.
The content of the invention
The purpose of this utility model is directed to the above-mentioned problems in the prior art, there is provided a kind of axiality more it is high simultaneously
And the more stable oil immersed type deep-well pump frame of operation.
The purpose of this utility model can be realized by following technical proposal：A kind of oil immersed type deep-well pump frame, including circle
The pump housing of cylindricality and the motor being arranged in the pump housing, the bottom of the pump housing cave inward to form limited step, the motor
Bottom is set with the pump housing by limited step card, and the bottom of the pump housing is accumulator, and the bottom of the motor is provided with thrust
Bearing, it is characterised in that limited step lower section is located on the inwall of the accumulator and is provided with positioning seat, on described positioning seat
The locating slot for being available for thrust bearing to snap in is offered, the center of the locating slot offers and is available for machinery oil circulation in accumulator
Oil-through hole, is structure as a whole between described positioning seat and the pump housing.
In a kind of above-mentioned oil immersed type deep-well pump frame, lubricating cup is provided with described accumulator, described lubricating cup leads to
Jump ring is crossed to fix.
In a kind of above-mentioned oil immersed type deep-well pump frame, the bottom surface of the positioning seat is globoidal structure.
The technique effect of this oil immersed type deep-well pump frame is：It is integrated and the pump housing between by being set in oil storage chamber interior walls
The positioning seat of structure, by the locating slot on positioning seat by the thrust bearing location and installation of motor bottom, only leads to relative to tradition
Cross limited step to position due to being integrative-structure locating slot higher in the axiality after opening up between the pump housing motor, make deep-well
The operation of pump is more stablized, for the support force for further increasing positioning seat and the volume that increases accumulator sets its bottom surface
It is globoidal structure.
This oil immersed type deep well pump makes motor internal fill machinery oil and and oil storage by opening up oil-through hole on locating slot
Room is circulated, and rapid the transferring out of the heat that can be come out motor operation is come, then is dispersed into water therefore is dissipated by the pump housing
Thermal effect is more preferable.
Compared with prior art, this oil immersed type deep-well pump frame makes it by setting the positioning seat of integrative-structure in the pump housing
Have the advantages that axiality is higher and it is more stable to run.
