Abstract
The invention discloses an array permanent magnet magnetic suspension shielding electric pump comprising a base portion, a power portion, a pump body portion and a transmission portion. The array permanent magnet magnetic suspension shielding electric pump is characterized in that the transmission portion is fixed on the base portion via a first permanent magnet bearing (4) and a second permanent magnet bearing (6). The array permanent magnet magnetic suspension shielding electric pump has the advantage that the mixing magnetic suspension shielding electric pump device is reasonable in design and power saving, and can realize high rotating speed, is no frictional wear, is stable in performance, long in service life, is free of pollution and is small in maintaining work by utilizing advantages of the array permanent magnet loop array and the Halbach array combining the permanent magnet and the electric magnet.
Description
Technical field
The invention belongs to liquid transfer pump technical field, more particularly, belong to a kind of array permanent magnetism magnetic suspension shielded electric-pump.
Background technique
When in prior art, electromagnetic suspension shielded electric-pump unit is worked, energy consumption is higher is the problem of a generality.In tradition permanent magnetism magnetic suspension shielded electric-pump unit, bearing capacity is not high, working life is short is the problem of a generality.Main cause is that traditional Permanent-magnet bearing is the simple annular radial magnet steel that magnetizes, and low bearing capacity easily touches the fault of rubbing when rotating speed is very high, affects the normal work of shielded electric-pump.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art part and a kind of permanent magnetism magnetic suspension shielded electric-pump device is provided, thereby effectively solve the problems of the prior art.
A kind of array permanent magnetism magnetic suspension shielded electric-pump of the present invention, comprises base part, power section, pump housing part and drive part; It is characterized in that: described drive part is fixed on base part by the first Permanent-magnet bearing, the second Permanent-magnet bearing.
According to above-described array permanent magnetism magnetic suspension shielded electric-pump, preferably: described the first Permanent-magnet bearing comprises internal magnetic ring, outer magnetic ring, outer magnetic ring magnetic array, internal magnetic ring magnetic array.
According to above-described array permanent magnetism magnetic suspension shielded electric-pump, preferably: described the second Permanent-magnet bearing comprises internal magnetic ring, outer magnetic ring, outer magnetic ring magnetic array, internal magnetic ring magnetic array.
The invention has the beneficial effects as follows: described permanent magnetism magnetic suspension shielded electric-pump device, it is reasonable in design, energy-conservation, utilize the advantage of the Halbach array that array permanent magnetism ring array and permanent magnetism combines with electromagnetism can realize higher rotation speed, without fretting wear, reliable performance, the life-span is long, pollution-free, maintenance load is little.
