Abstract
A kind of magnetic drive pump axial force automatic balancing structure, including impeller and balance plate washer, the rear portion of balance plate washer and impeller, which is movably connected and encloses, generates a counter balance pocket.It balances plate washer and includes top lip of slice and aulaeum, impeller rear portion is equipped with sealing ring, boss and balance hole；The sealing ring of impeller is connected with balancing the top lip of slice slip of plate washer, and damping is given birth to the liquid flow movable property of impeller outlet and counter balance pocket；Gap delta is equipped 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 hole.The configuration of the present invention is simple, good balance effect.The twice formed by counter balance pocket and sealing ring with balance plate washer top lip of slice, impeller boss with balance plate washer aulaeum damp, and realize the fully automated balance of axial force in the range of magnetic drive pump full flow.
Description
Technical field
The present invention relates to a kind of pump more particularly to a kind of magnetic drive pump axial force automatic balancing structures.
Background technology
The axial force balance of magnetic drive pump is to be related to the normal work of pump and the key technology in service life, common in magnetic drive pump
There are balance hole, back blade etc., and actually these balance modes are all unable to complete equipilibrium axial force, be easy to cause parts in pump
Wear damage, make the service life of magnetic drive pump reduce.
Invention content
The purpose of the present invention is exactly to solve the above-mentioned problems, to provide a kind of magnetic drive pump axial force automatic balancing structure.
In order to achieve the above object, present invention employs following technical schemes：A kind of magnetic drive pump axial force automatic balancing knot
Structure, including impeller and balance plate washer, the rear portion of balance plate washer and impeller, which is movably connected and encloses, generates a counter balance pocket.
The balance plate washer includes top lip of slice and aulaeum, and the impeller rear portion is equipped with sealing ring, boss and balance hole；Institute
The sealing ring for stating impeller is connected with the top lip of slice slip for balancing plate washer, and resistance is given birth to the liquid flow movable property of impeller outlet and counter balance pocket
Buddhist nun；Gap delta is equipped between the boss of the impeller and the aulaeum for balancing plate washer, to the liquid flow movable property of counter balance pocket and balance hole
Raw pressure damping.
The δ is 1-2.5mm.
The present invention is had the following advantages that and feature as a result of above technical scheme：
1st, it is simple in structure：Ingenious in design, 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 that labial lamina is formed, realizes the fully automated balance of axial force in the range of magnetic drive pump full flow.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Specific embodiment
Referring to Fig. 1, magnetic drive pump axial force automatic balancing structure of the invention including impeller 1 and balance plate washer 2, balances shelves
The rear portion of plate and impeller, which is movably connected and encloses, generates a counter balance pocket 3.
Balance plate washer 2 in the present invention includes top lip of slice 21 and aulaeum 22, and 1 rear portion of impeller is equipped with sealing ring 11, boss
12 and balance hole 13, wherein, the sealing ring of impeller is connected with balancing the top lip of slice slip of plate washer, to impeller outlet and counter balance pocket
The life damping of liquid flow movable property；Gap delta is equipped between the boss of impeller and the aulaeum for balancing plate washer, to counter balance pocket and balance hole
Liquid flow movable property gives birth to pressure damping.δ is 1-2.5mm.
The present invention controls impeller ring with balancing the gap of plate washer top lip of slice by Theoretical Design, to impeller outlet with putting down
The liquid flow movable property life damping of weighing apparatus chamber, control impeller boss and the gap of balance plate washer aulaeum are δ, to counter balance pocket and balance hole
Liquid flow movable property life pressure damping.
Impeller is with inlet pressure of the pressure of counter balance pocket that balance plate washer is encircled into more than impeller and less than the outlet of impeller
Pressure, the internal rotor assembly of the magnetic drive pump of design can be in axially free floating, and when magnetic force pump operation, internal rotor assembly is by liquid
Axial force caused by body pressure differential generates axial floating, and the pressure of counter balance pocket changes with the flying height δ of impeller and changed, and works as leaf
In declared working condition, for impeller suspended on some determining position, the resultant force of the axial force of magnetic drive pump is zero to wheel when a little, works as magnetic force
The operating mode of pump is changed towards the direction that flow reduces, the increase of impeller outlet pressure, and the resultant force direction of the axial force of magnetic drive pump is electronic
Generator terminal, impeller float to motor terminal, and gap delta reduces therewith, so as to which the pressure for making counter balance pocket reduces therewith.When pump is in new work
After condition point is stable, the adjust automatically for balancing cavity pressure at this time is in axial force balance state always using pump, protects magnetic
The parts of power pump are not damaged by axial force.
