Abstract
The utility model belongs to water pump technology, refers in particular to a kind of thrust sealing structure of sewage pump.The utility model discloses a kind of thrust sealing structures of sewage pump, include motor shaft, bearing and bearing block are installed on the motor shaft, the shaft end outer wall of the motor shaft extends radially outwardly in inclined-plane, the shaft end is socketed with the sealing cover of axial movement, one side end face of bearing is provided with the sealing ring being socketed on motor shaft, the sealing ring coordinates with motor shaft, bearing and bearing block sealing, the top surface of the sealing ring is higher than the top surface of bearing block, the edge bending of the sealing cover, the bending of the sealing cover are in bearing block end face outer rim and correspond to.Simple in structure, easy for installation, sealing performance is excellent, while sealing ring is also avoided to scratch damage by the solid particle in impurity, it is therefore prevented that the fibre object impurity in sewage is wrapped in motor shaft, protection motor safe handling.
Description
Technical field
The utility model belongs to water pump technology, refers in particular to a kind of thrust sealing structure of sewage pump.
Background technology
Sewage pump belongs to one kind of Non-blinding pump, has a variety of patterns, mainly for delivery of municipal sewage, excrement or contain
The liquid of fiber.Due to containing the easily fibre object of winding or pack in transported medium, therefore this kind pump runner is easy to block, and pumps
Once pump cisco unity malfunction can be made or even burn motor by being blocked, so as to cause blowdown not smooth, to urban life and environmentally friendly band
Carry out serious influence.Liquid enters inside motor in order to prevent, and water pump on the market is all by being set on motor shaft at present
Mechanical seal, and sewage pump, due to containing impurity in the medium of conveying, common sealing structure is easily by the solid in impurity
Grain damage, the sealing effect that causing sealed ring deformation makes water pump decline, motor entering water may be made when serious and is burnt out.
Utility model content
First, technical problems to be solved
The purpose of this utility model is for the above problem present in the prior art, provides a kind of simple in structure and energy
The thrust sealing structure of enough sewage pumps that motor is effectively avoided to burn out.
2nd, technical solution
In order to solve the above technical problems, the thrust sealing structure of the utility model sewage pump, includes motor shaft, above-mentioned electricity
Bearing and bearing block are installed on arbor, wherein, the shaft end outer wall of above-mentioned motor shaft extends radially outwardly in inclined-plane, shaft end set
Be connected to the sealing cover of axial movement, above-mentioned one side end face of bearing is provided with the sealing ring being socketed on motor shaft, the sealing ring with
Motor shaft, bearing and bearing block sealing cooperation, the top surface of above-mentioned sealing ring are higher than the top surface of bearing block, the edge of above-mentioned sealing cover
Bending, the bending of above-mentioned sealing cover are in bearing block end face outer rim and correspond to.
As an optimization, the outer wall of above-mentioned motor shaft offers the seal groove of arc surface, and above-mentioned sealing ring is sealed with seal groove
Cooperation.
3rd, the beneficial effects of the utility model
Simple in structure, easy for installation, during sewage is conveyed, hydraulic pressure can axially elapse sealing cover, sealing cover
Inner bottom surface can be pressed on sealing ring, reached and further sealed and prevent leak to protect motor, while also avoid sealing ring quilt
Solid particle in impurity scratches damage, it is therefore prevented that the fibre object impurity in sewage is wrapped in motor shaft, and protection motor makes safely
With.
Description of the drawings
Fig. 1 is the thrust sealing structure cross-sectional view of the utility model sewage pump.
In figure, 1 is motor shaft, and 2 be bearing, and 3 be bearing block, and 4 be sealing cover, and 5 be sealing ring, and 6 be bending.
Specific embodiment
The thrust sealing structure of the utility model sewage pump is described further below in conjunction with the accompanying drawings：
Embodiment one：As shown in Figure 1, the thrust sealing structure of the utility model sewage pump, includes motor shaft 1, on
It states and bearing 2 and bearing block 3 is installed on motor shaft 1, the shaft end outer wall of above-mentioned motor shaft 1 extends radially outwardly in inclined-plane, the axis
End cap is connected to the sealing cover 4 of axial movement, and above-mentioned 2 one side end face of bearing is provided with the sealing ring 5 being socketed on motor shaft 1, should
Sealing ring 5 coordinates with motor shaft 1, bearing 2 and the sealing of bearing block 3, and specifically, the outer wall of motor shaft 1 offers arc surface
Seal groove, above-mentioned sealing ring 5 coordinate with seal groove sealing, and the top surface of above-mentioned sealing ring 5 is higher than the top surface of bearing block 3, above-mentioned close
The edge bending 6 of capping 4, the bending 6 of above-mentioned sealing cover 4 are in 3 end face outer rim of bearing block and correspond to.
In use, motor shaft 1 rotates and the impeller being fixedly mounted on motor shaft 1 is driven to rotate together, herein
In the process, sewage is constantly extracted, and during sewage is extracted, the hydraulic pressure of sewage can be applied on sealing cover 4, made close
4 axial movement of capping, this is made up to further but also the inner bottom surface of sealing cover 4 can be tightly pressed against the end face of sealing ring 5
Sealing；In addition, when the axial movement of sealing cover 4 is extruded on sealing ring 5, can just be covered in axis at the bending 6 at 4 edge of sealing cover
In bearing 3, fibre object or particulate contaminant in sewage can be effectively kept out, sealing ring 5 and motor shaft 1 can be effectively protected
Safe handling.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
