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 by being blocked, or even burn motor, so as to cause blowdown not smooth, to urban life and environmentally friendly band
Carry out serious influence.Liquid enters motor internal 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 magnetic seal structure of enough sewage pumps for effectively avoiding motor from burning out.
2nd, technical solution
In order to solve the above technical problems, the magnetic seal 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
The sealing cover of axial movement is connected to, above-mentioned one side end face of bearing is provided with the sealing ring being socketed on motor shaft, the sealing ring point
Face sealing not corresponding with motor shaft, bearing and bearing block coordinates, and the inner bottom surface of above-mentioned sealing cover is installed with magnet ring A, on
The side end face for stating sealing ring is provided with magnet ring B, and above-mentioned magnet ring A is opposite with magnet ring B homopolarities, and the end face of above-mentioned sealing ring is embedded with
Separator disk, above-mentioned magnet ring B one sides are provided with and the matched plug ring of separator disk inside groove.
As an optimization, the edge bending of above-mentioned sealing cover, the bending of above-mentioned sealing cover are in bearing block end face outer rim and correspond to.
3rd, the beneficial effects of the utility model
It is simple in structure, easy for installation；Sealing effect is good and prevents leak to protect motor, while also avoids sealing ring miscellaneous
Solid particle in matter scratches damage, it is therefore prevented that the fibre object impurity in sewage is wrapped in motor shaft, and protection motor safety uses.
Brief description of the drawings
Fig. 1 is the magnetic seal structural profile structure diagram of the utility model sewage pump；
Fig. 2 is the M portions enlarged drawing of Fig. 1.
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, and 7 be magnet ring
A, 8 be magnet ring B, and 9 be plug ring, and 10 be separator disk.
Embodiment
The magnetic seal structure of the utility model sewage pump is described further below in conjunction with the accompanying drawings：
Embodiment one：As illustrated in fig. 1 and 2, the magnetic seal structure of the utility model sewage pump, includes motor shaft 1,
Bearing 2 and bearing block 3 are installed, the shaft end outer wall of above-mentioned motor shaft 1 extends radially outwardly in inclined-plane, should on above-mentioned motor shaft 1
Shaft end is socketed with 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,
The sealing ring 5 is sealed with motor shaft 1, bearing 2 and 3 corresponding face of bearing block respectively to be coordinated, and the inner bottom surface of above-mentioned sealing cover 4 is fixed
Magnet ring A7 is installed, a side end face of above-mentioned sealing ring 5 is provided with magnet ring B8, and above-mentioned magnet ring A7 is opposite with magnet ring B8 homopolarities, on
The end face for stating sealing ring 5 is embedded with separator disk 10, and above-mentioned magnet ring B8 one sides are provided with and the matched plug of 10 inside groove of separator disk
Ring 9；The edge bending 6 of above-mentioned sealing cover 4, the bending 6 of above-mentioned sealing cover 4 are in 3 end face outer rim of bearing block and correspond to.
In actual use, motor shaft 1 rotates and drives the impeller being fixedly mounted on motor shaft 1 to rotate together,
In the process, sewage is constantly extracted, and during sewage is extracted, the hydraulic pressure of sewage can be applied on sealing cover 4,
Move axially sealing cover 4, it is constantly close to magnet ring B8 to be arranged on the magnet ring A7 of 4 bottom surface of sealing cover, due to magnet ring A7 and magnetic
Ring B8 is that homopolarity is opposite, and caused repulsion constantly can elapse magnet ring B8 along the axial direction of motor shaft 1, and be arranged on magnet ring
The plug ring 9 of B8 one sides can be stepped into the inside groove of separator disk 10, in the present embodiment, the shape in 9 single section of plug ring
To be trapezoidal, after plug ring 9 is inserted into 10 inside groove of separator disk, both sides separate separator disk 10 to the left and right, are extruded during separated
Sealing ring 5 so that sealing ring 5 is further sealed with the surface of motor shaft 1 and bearing block 3, can effective waterproof, with protection
Motor safety uses；In addition, when sealing cover 4 moves axially, can just be covered in bearing block 3 at the bending 6 at 4 edge of sealing cover
On, the fibre object or particulate contaminant in sewage can be effectively kept out, sealing ring 5 and the safety of motor shaft 1 can be effectively protected
Use.
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, some 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.
