Abstract
The rear portion of a kind of magnetic drive pump axial force automatic balancing structure, including impeller and balance plate washer, balance plate washer and impeller, which is movably connected and enclosed, produces a counter balance pocket.Balancing plate washer includes top lip of slice and aulaeum, and impeller rear portion is provided with sealing ring, boss and balance pipe；The sealing ring of impeller is connected with balancing the top lip of slice of plate washer and sliding, and impeller outlet and the life of the liquid flow movable property of counter balance pocket are damped；Gap delta is provided between the boss of impeller and the aulaeum for balancing plate washer, pressure damping is given birth to the liquid flow movable property of counter balance pocket and balance pipe.The utility model is simple in construction, good balance effect.Damped by counter balance pocket and sealing ring with balance plate washer top lip of slice, impeller boss and the twice of balance plate washer aulaeum formation, realize the fully automated balance of axial force in the range of magnetic drive pump full flow.
Description
Technical field
The utility model is related to a kind of pump, more particularly to a kind of magnetic drive pump axial force automatic balancing structure.
Background technology
The axial force balance of magnetic drive pump is commonly used in the key technology in the normal work and life-span for being related to pump, magnetic drive pump
There are balance pipe, back blade etc., and actually these balance modes are all unable to complete equipilibrium axial force, easily cause parts in pump
Wear damage, making the service life of magnetic drive pump reduces.
Utility model content
The purpose of this utility model, exactly in order to solve the above problems, there is provided a kind of magnetic drive pump axial force automatic balancing knot
Structure.
In order to achieve the above object, the utility model employs following technical scheme：A kind of magnetic drive pump axial force is put down automatically
Weigh structure, including impeller and balance plate washer, and the rear portion of balance plate washer and impeller, which is movably connected and enclosed, produces a counter balance pocket.
The balance plate washer includes top lip of slice and aulaeum, and the impeller rear portion is provided with sealing ring, boss and balance pipe；Institute
Top lip of slice of the sealing ring for stating impeller with balancing plate washer, which is slided, to be connected, and impeller outlet and the life of the liquid flow movable property of counter balance pocket are hindered
Buddhist nun；Gap delta is provided between the boss of the impeller and the aulaeum for balancing plate washer, to counter balance pocket and the liquid flow movable property of balance pipe
Raw pressure damping.
The δ is 1-2.5mm.
The utility model has the following advantages that and feature as a result of above technical scheme：
1st, it is simple in construction：Design is ingenious, and rationally distributed, structure and manufacture craft are simple.
2nd, good balance effect：By counter balance pocket and sealing ring with balance plate washer top lip of slice, impeller boss with balancing under plate washer
The twice damping of labial lamina formation, realizes the fully automated balance of axial force in the range of magnetic drive pump full flow.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
Referring to Fig. 1, magnetic drive pump axial force automatic balancing structure of the present utility model, including impeller 1 and balance plate washer 2, put down
The rear portion of weighing apparatus plate washer and impeller, which is movably connected and enclosed, produces a counter balance pocket 3.
Balance plate washer 2 in the utility model includes top lip of slice 21 and aulaeum 22, the rear portion of impeller 1 provided with sealing ring 11,
Boss 12 and balance pipe 13, wherein, the sealing ring of impeller is connected with balancing the top lip of slice of plate washer and sliding, to impeller outlet and balance
The liquid flow movable property life damping of chamber；Gap delta is provided between the boss of impeller and the aulaeum for balancing plate washer, to counter balance pocket and balance
The liquid flow movable property life pressure damping in hole.δ is 1-2.5mm.
The utility model controls the gap of impeller ring and balance plate washer top lip of slice by Theoretical Design, to impeller outlet
Damping is given birth to the liquid flow movable property of counter balance pocket, it is δ with the gap of balance plate washer aulaeum to control impeller boss, to counter balance pocket with putting down
The liquid flow movable property life pressure damping in weighing apparatus hole.
The pressure for the counter balance pocket that impeller is encircled into balance plate washer is less than the outlet of impeller more than the inlet pressure of impeller
Pressure, the internal rotor assembly of the magnetic drive pump of design can float axially free, and when magnetic force pump operation, internal rotor assembly is by liquid
Axial force caused by body pressure differential, which is produced, axially floats, and the pressure of counter balance pocket changes and changed with the flying height δ of impeller, works as leaf
Wheel in declared working condition impeller suspended in some defined location, when a little the axial force of magnetic drive pump to make a concerted effort be zero, work as magnetic force
The direction that the operating mode of pump reduces towards flow changes, the increase of impeller outlet pressure, points to the axial force of magnetic drive pump with joint efforts electronic
Generator terminal, impeller floats to motor terminal, and gap delta reduces therewith, so that the pressure of counter balance pocket reduces therewith.When pump is in new work
After condition point is stable, the adjust automatically for now balancing cavity pressure is in axial force balance state all the time using pump, protects magnetic
The parts of power pump are not damaged by axial force.
