The present invention solves the technical problem of a kind of Impeller Pumps with Active Magnetic Bearings of sewage disposal device of offer, It has been largely overcoming that common vane pump is easy to wear, need sealed shortcoming to be continuously run there is provided a kind of long-term No leakage, There is the Novel leaf wheel pump of good application prospect.
In order to solve the above technical problems, one aspect of the present invention is:There is provided a kind of sewage disposal device Impeller Pumps with Active Magnetic Bearings, including rotating shaft bar, bearing sleeve, shaft position sensor, radial displacement transducer, axial direction Magnetic bearing stator, stator coil, vane rotor magnet steel and vane rotor, described rotating shaft bar are horizontally set on bearing sleeve Centre position, described shaft position sensor is horizontally set on the front end of rotating shaft bar, and described radial displacement transducer is vertical It is arranged on rotating shaft bar and positioned at the front end of bearing sleeve, described vane rotor magnet steel and vane rotor are arranged at rotating shaft bar Go up and be located inside bearing sleeve, described axial magnetic bearing stator is respectively provided on the periphery of vane rotor, described stator Coil is arranged on the periphery of vane rotor magnet steel.
In a preferred embodiment of the present invention, described vane rotor magnet steel is located between two vane rotors.
In a preferred embodiment of the present invention, described Impeller Pumps with Active Magnetic Bearings is also fixed including radial direction magnetic bearing Son, described radial direction magnetic bearing stator is vertically provided between axial magnetic bearing stator and stator coil respectively.
In a preferred embodiment of the present invention, described radial direction magnetic bearing stator is incited somebody to action by the retainer ring of non-magnet material Each group electromagnet core, which is fixed together, to be combined.
In a preferred embodiment of the present invention, described vane rotor is by the excellent soft magnetic materials manufacture of magnetic property Form.
In a preferred embodiment of the present invention, described bearing sleeve uses totally enclosed structure.
The beneficial effects of the invention are as follows:The Impeller Pumps with Active Magnetic Bearings of the sewage disposal device of the present invention, very big Overcome that common vane pump is easy to wear, need sealed shortcoming to be continuously run there is provided a kind of long-term No leakage in degree, there is good Application prospect Novel leaf wheel pump.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, makes required in being described below to embodiment Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for For those of ordinary skill in the art, on the premise of not paying creative work, it can also obtain other according to these accompanying drawings Accompanying drawing, wherein:
Fig. 1 is the structural representation of a preferred embodiment of sand blasting room of the present invention;
Reference is as follows:1st, rotating shaft bar, 2, bearing sleeve, 3, shaft position sensor, 4, radial displacement transducer, 5, axially Magnetic bearing stator, 6, stator coil, 7, vane rotor magnet steel, 8, vane rotor, 9, radial direction magnetic bearing stator.
Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model that the present invention is protected Enclose.
As shown in figure 1, the embodiment of the present invention includes:
A kind of Impeller Pumps with Active Magnetic Bearings of sewage disposal device, including rotating shaft bar 1, bearing sleeve 2, axial displacement sensing Device 3, radial displacement transducer 4, axial magnetic bearing stator 5, stator coil 6, vane rotor magnet steel 7 and vane rotor 8, it is described Rotating shaft bar 1 be horizontally set on the centre position of bearing sleeve 2, described shaft position sensor 3 is horizontally set on rotating shaft bar 1 Front end, described radial displacement transducer 4 is vertically set on rotating shaft bar 1 and positioned at the front end of bearing sleeve 2, described leaf Wheel rotor magnetic steel 7 and vane rotor 8 are arranged on rotating shaft bar 1 and inside bearing sleeve 2, and described axial magnetic bearing is determined Son 5 is respectively provided on the periphery of vane rotor 8, and described stator coil 6 is arranged on the periphery of vane rotor magnet steel 7.Wherein, Described vane rotor magnet steel 7 is located between two vane rotors 8.
Further, described Impeller Pumps with Active Magnetic Bearings also includes radial direction magnetic bearing stator 9, described radial direction magnetic axis Stator 9 is held to be vertically provided at respectively between axial magnetic bearing stator 5 and stator coil 6.Wherein, described radial direction magnetic bearing stator 9 be that each group electromagnet core is fixed together by the retainer ring of non-magnet material to combine, therefore magnetic circuit is independent, is not present Magnetic coupling problem;In order to prevent on electromagnetic bearing stator each group electromagnetism iron circuit, stator blade wheel magnetic circuit, thrust bearing magnetic circuit etc. it Between produce magnetic coupling, influence quiet, the dynamic property of electromagnetic bearing, thus by the internal surface of bearing sleeve 2 plate not magnetic conduction and Erosion-resisting material;In working condition, because the gap between rotor and stator is hydraulically full, described bearing sleeve 2 Using totally enclosed structure, any fluid composition can not possibly be leaked to outside bearing sleeve 2.
In the present embodiment, described vane rotor 8 is by the excellent soft magnetic materials of magnetic property(Silicon steel)It is fabricated by;It is described Shaft position sensor 3 and radial displacement transducer 4 either level or vertical direction, be all differential with two sensors The displacement of vane rotor 8 is detected, therefore two screwed holes of placement sensor must be coaxially conllinear in one direction, level The requirement of certain perpendicularity must is fulfilled for the axis of vertical direction.The import and export part of bearing sleeve 2 is by lucite system Make, enabling clearly see the running situation of vane rotor 8.
In use, only needing to access 220V alternating currents in outside, open after controlling switch, pump can just be realized long-term continuous Operating.
In summary, the Impeller Pumps with Active Magnetic Bearings of sewage disposal device of the invention, is largely overcoming Common vane pump is easy to wear, need sealed shortcoming to continuously run there is provided a kind of long-term No leakage, there is good application prospect Novel leaf wheel pump.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks Domain, is included within the scope of the present invention.
