Abstract
The utility model discloses a kind of proof submersible sand discharging pump with alignment bearing, including the pump housing, it is arranged on main shaft in the pump housing, pump cover and impeller, the water pilot bearing coaxial with the main shaft is provided with the pump cover, the water pilot bearing includes the bearing block fixed with the pump cover, guide bearing is provided with the bearing block, axle sleeve in the guide bearing, is provided with, the bottom of the main shaft is connected with the impeller through the axle sleeve.One water pilot bearing is set between main shaft and impeller, and the medium cooling that Bearing support water pump is pumped, the bearing ensure that cantilever end main shaft amount of deflection is unlikely to excessive.The guide bearing constitutes friction pair by the bearing block on the axle sleeve and pump cover on main shaft, it is ensured that the stable operation of pump, reduces the phenomenon of choma abrasion, it is to avoid the appearance of spindle abrasion phenomenon, extends the service life of unit.
Description
Technical field
This utility model is related to proof submersible sand discharging pump, especially, is related to a kind of proof submersible sand discharging pump with alignment bearing.
Background technology
At present, the pump section of proof submersible sand discharging pump uses a main shaft with submersible motor.But, it is past in large diving dredge pump
Toward needing to use thrust bearing, this results in the lengthening of impeller cantilever.As proof submersible sand discharging pump belongs to receded disk impeller, deposit
In theoretical radial force, cantilever is long to cause main shaft cantilever lateral deflection to become big, impeller port ring serious wear, with the mill of choma
Damage and deepen, main shaft occurs to wear and tear in machine sealing position, causes main shaft to damage, with abrasion aggravation, substantially shaking occurs in whole pump, and affects whole
Pump stable operation.
Utility model content
This utility model purpose is to provide a kind of proof submersible sand discharging pump with alignment bearing, to solve proof submersible sand discharging pump cantilever
It is long that main shaft cantilever lateral deflection can be caused to become big, impeller port ring serious wear, as the abrasion of choma is deepened, main shaft is in machine sealing position
Generation is worn and torn, and causes main shaft to damage, and with abrasion aggravation, substantially shaking occurs in whole pump, and affects the technology of whole pump stable operation to ask
Topic.
For achieving the above object, this utility model provides a kind of proof submersible sand discharging pump with alignment bearing, including the pump housing, arranges
Main shaft, pump cover and impeller in the pump housing, is provided with the water pilot bearing coaxial with the main shaft, the water on the pump cover
Guide bearing includes the bearing block fixed with the pump cover, is provided with guide bearing, is provided with the guide bearing in the bearing block
Axle sleeve, the bottom of the main shaft are connected through the axle sleeve with the impeller.
Further, the two ends of the axle sleeve protrude from the two ends of the bearing block and the guide bearing respectively.
Further, the bearing block is fixed with the pump cover by screw.
This utility model has the advantages that：
One water pilot bearing is set between main shaft and impeller, and the medium cooling that Bearing support water pump is pumped, the bearing ensure
Cantilever end main shaft amount of deflection is unlikely to excessive.The guide bearing constitutes friction pair by the bearing block on the axle sleeve and pump cover on main shaft, protects
The stable operation of card pump, reduces the phenomenon of choma abrasion, it is to avoid the appearance of spindle abrasion phenomenon, extends the service life of unit.
Description of the drawings
Below with reference to figure, this utility model is described in further detail.Constitute the accompanying drawing of the part of the application
Further understand to of the present utility model for providing, schematic description and description of the present utility model is used to explain this reality
With new, do not constitute to improper restriction of the present utility model.In the accompanying drawings：
Fig. 1 is a kind of structural representation of the proof submersible sand discharging pump with alignment bearing of this utility model；
Fig. 2 is the enlarged diagram in a regions in Fig. 1.
Specific embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2, a kind of proof submersible sand discharging pump with alignment bearing, including the pump housing 1 are referred to, is arranged in the pump housing 1
Main shaft 2, pump cover 3 and impeller 4, the water pilot bearing coaxial with the main shaft 2, the water pilot bearing are provided with the pump cover 3
Including the bearing block 5 fixed with the pump cover 3, guide bearing 6 is provided with the bearing block 5, in the guide bearing 6, axle is provided with
Set 7, the bottom of the main shaft 2 is connected through the axle sleeve 7 with the impeller 4.One water is set between main shaft 2 and impeller 4
Guide bearing, the medium cooling that Bearing support water pump is pumped, the bearing ensure that cantilever end main shaft amount of deflection is unlikely to excessive.The guide bearing by
The composition friction pair of bearing block 5 on axle sleeve 7, guide bearing 6 and pump cover 3 on main shaft, it is ensured that the stable operation of pump, reduces choma mill
The phenomenon of damage, it is to avoid the appearance of 2 wear phenomenon of main shaft, extends the service life of unit.
Preferably, the two ends of the axle sleeve 7 protrude from the two ends of the bearing block 5 and the guide bearing 6 respectively.That is the axle
The length of set 7 is greater than bearing block 5 and guide bearing 6, so protects bearing block 5 not frayed with the oral area of guide bearing 6.
Preferably, the bearing block 5 is fixed with the pump cover 3 by screw 8.So facilitate the installation of bearing block 5.
Preferred embodiment of the present utility model is the foregoing is only, this utility model is not limited to；For this
For the technical staff in field, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. are should be included within protection domain of the present utility model.
