Abstract
The present invention relates to pump, particularly relate to a kind of axial force magnetic force self balancing device.It comprises fixing magnetic ring gland, the magnetic ring assembly that floats, floating magnetic ring axle sleeve.In the inner chamber that fixing magnetic ring gland and fixing magnetic force ring seat are formed, pump shaft is provided with floating magnetic ring axle sleeve, the magnetic ring axle sleeve that floats is provided with floating magnetic ring assembly; Described floating magnetic ring assembly two ends are symmetrically arranged with fixing magnetic ring assembly A, fixing magnetic ring assembly B and block, and are locked on pump shaft by locking nut.The present invention can make the axial force of petrochemical process pump obtain autobalance, decreases bearing and reduces its service time because bearing axial force, improves operation stability and the reliability of pump, thus extends the life cycle life-span of pump.The axial force that can produce in pump operation process is effectively balanced, and reduces the rate of fault of pump, improves the effective rate of utilization of pump, reduces operation and maintenance cost and the cost of production of enterprise simultaneously.
Description
Technical field
the present invention relates to pump, particularly relate to a kind of axial force magnetic force self balancing device.
Background technique
the axial force that pump operationally produces generally is born by bearing, particularly the axial force of large discharge, high-lift single double-impeller pump and multistage centrifugal pump generation is larger, seriously reduce the working life in cycle of bearing in pump, the rate of fault of pump increases, add operation and maintenance cost and the cost of production of enterprise simultaneously, therefore the axial force produced in pump operation process effectively must be balanced, stability and the reliability of pump operation could be improved, be extended the working life in cycle of pump.
Summary of the invention
Object of the present invention will provide a kind of axial force magnetic force self balancing device exactly, and it can overcome the above problem that prior art exists.The object of the present invention is achieved like this, axial force magnetic force self balancing device, comprises fixing magnetic ring gland, floating magnetic ring assembly, float magnetic ring axle sleeve,
it is characterized in that:in the inner chamber that fixing magnetic ring gland and fixing magnetic force ring seat are formed,
pump shaft is provided withfloat magnetic ring axle sleeve, and the magnetic ring axle sleeve that floats is provided with floating magnetic ring assembly; Described floating magnetic ring assembly two ends are symmetrically arranged with fixing magnetic ring assembly A, fixing magnetic ring assembly B and block, and are locked on pump shaft by locking nut.
The magnetic pole at described floating magnetic ring assembly two ends should to fix magnetic ring assembly A identical with the corresponding magnetic pole of fixing magnetic ring assembly B with two ends, namely should be and be both N pole or be both S pole.
The end face that described floating magnetic ring assembly is corresponding with between fixing magnetic ring assembly A and fixing magnetic ring assembly B, reserved fixing gap, guarantee to produce friction, use the principle that the less repulsive force of distance between magnetic pole homopolar-repulsion, magnetic pole is larger, the axial force produced when carrying out autobalance pump operation.
The present invention can make the axial force of petrochemical process pump obtain autobalance, decreases bearing and reduces its service time because bearing axial force, improves operation stability and the reliability of pump, thus extends the life cycle life-span of pump.The axial force that can produce in pump operation process is effectively balanced, and reduces the rate of fault of pump, improves the effective rate of utilization of pump, reduces operation and maintenance cost and the cost of production of enterprise simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
1. fixing magnetic ring gland, 2. locking nut, 3. float magnetic ring axle sleeve, 4. fixing magnetic ring assembly A, and 5. float magnetic ring assembly, 6. fixing magnetic force ring seat, 7. fixing magnetic ring assembly B, 8. pump shaft.
embodiment:
Below in conjunction with accompanying drawing 1, the present invention will be further described:
In the drawings, axial force magnetic force self balancing device, first fixing magnetic ring assembly 7 is loaded in fixing magnetic force ring seat 6, be connected and fixed with the tail end of pump, the magnetic ring assembly 5 that floats positions fastening with floating magnetic ring axle sleeve 3 by the requirement of axial design fitted position, the magnetic ring axle sleeve 3 that floats loads on pump shaft 8 together with floating magnetic ring assembly 5, lock with locking nut 2 again, fixing magnetic ring assembly 4 is loaded after in fixing magnetic ring gland 1, with fixing magnetic force ring seat 6 bolt, nut check, must be noted that during installation that the magnetic pole that the magnetic pole at floating magnetic ring assembly 5 two ends should fix magnetic ring assembly 4 corresponding with fixing magnetic ring assembly 7 with two ends is identical, namely should be and be both N pole or S pole, and reserved fixing gap makes floating magnetic ring assembly 5 end face corresponding with fixing magnetic ring assembly 4 and fixing magnetic ring assembly 7 not produce friction, use magnetic pole homopolar-repulsion, the principle that the less repulsive force of distance between magnetic pole is larger, the axial force produced when carrying out autobalance pump operation, thus guarantee that pump can be normal, steady running, extend the working life in cycle of pump.
