Abstract
The invention relates to a pump, in particular to an axial force and magnetic force self-balancing device which comprises a fixed magnetic ring gland, a floating magnetic ring component and a floating magnetic ring shaft sleeve, wherein in a cavity formed by the fixed magnetic ring gland and a fixed magnetic ring seat, the floating magnetic ring shaft sleeve is arranged on a pump shaft, and the floating magnetic ring component is arranged on the floating magnetic ring shaft sleeve; and fixed magnetic ring components A, fixed magnetic ring components B and check blocks are symmetrically arranged at two ends of the floating magnetic ring component and locked on the pump shaft through locknuts. According to the axial force and magnetic force self-balancing device, axial force of a petrochemical engineering process pump is balanced automatically, the condition that the use time of a bearing is shortened due to the fact the bearing bears the axial force is reduced, and the running stability and the running reliability of the pump are improved, so that the service life of the pump is prolonged, the axial force produced in a running process of the pump is effectively balanced, the fault rate of the pump is reduced, the effective utilization rate of the pump is increased, and the operation maintenance expenses and the production cost of an enterprise are reduced at the same time.
Description
Technical field
The present invention relates to pump, particularly relate to a kind of axial force magnetic force self balancing device.
Background technique
Pump produces when operation axial force is generally born by bearing, particularly the axial force that produces of large flow, high-lift single double-impeller pump and multistage centrifugal pump is larger, seriously reduced the working life in cycle of bearing in pump, the rate of fault of pump increases, operation and maintenance cost and the cost of production of enterprise have been increased simultaneously, therefore the axial force produced in the pump operation process must be obtained to effective balance, could improve stability and the reliability of pump operation, extend the working life in cycle of pump.
Summary of the invention
Purpose 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, and axial force magnetic force self balancing device comprises fixedly magnetic ring gland, the magnetic ring assembly that floats, the magnetic ring axle sleeve that floats,
It is characterized in that:Fixedly in magnetic ring gland and inner chamber that fixedly the magnetic force ring seat forms,
On pump shaft, be provided withUnsteady magnetic ring axle sleeve, be provided with the magnetic ring assembly that floats on the magnetic ring axle sleeve that floats; Described unsteady magnetic ring assembly two ends are symmetrically arranged with fixedly magnetic ring assembly A, fixedly magnetic ring assembly B and block, and are locked on pump shaft by locking nut.
The magnetic pole at described unsteady magnetic ring assembly two ends should with the fixing magnetic ring assembly A and fixedly the corresponding magnetic pole of magnetic ring assembly B is identical in two ends, namely should be and be both the N utmost point or be both the S utmost point.
Described unsteady magnetic ring assembly and fixing magnetic ring assembly A and fixing corresponding end face between magnetic ring assembly B, reserved fixing gap, guarantee can not produce friction, use the larger principle of the less repulsive force of distance between magnetic pole homopolar-repulsion, magnetic pole, the axial force produced while carrying out the autobalance pump operation.
The present invention can make the axial force of petrochemical process pump obtain autobalance, has reduced bearing and has reduced its service time because bearing axial force, has improved operation stability and the reliability of pump, thereby has extended the life cycle life-span of pump.The axial force that can produce in the pump operation process obtains effective balance, reduces the rate of fault of pump, improves the effective rate of utilization of pump, reduces simultaneously operation and maintenance cost and the cost of production of enterprise.
