Abstract
The utility model discloses an array permanent-magnet magnetic suspension shielding electric pump which comprises a substrate portion, a power portion, a pump body portion and a transmission portion, and is characterized in that the transmission portion is fixed on the substrate portion through a first permanent-magnet bearing (4) and a second permanent-magnet bearing (6). The array permanent-magnet magnetic suspension shielding electric pump has the advantages of being reasonable in design, energy-saving, capable of achieving high revolving speed through utilization of advantages of an array permanent magnet ring array and a Halbach array with combination of permanent magnetism and electromagnetism, free of friction wear, reliable in performance, long in service life, free of pollution, and small in maintenance workload.
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 electromagnetic suspension shielded electric-pump unit was worked in the prior art, energy consumption is higher to be the problem of a generality.In the 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 bumps the fault of rubbing when rotating speed is very high, affect the normal operation 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 the 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, preferred: 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, preferred: 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.
