Abstract
The invention discloses an array permanent magnet bearing magnetic drive pump comprising a base portion, a power portion, a pump body portion and a transmission portion. The array permanent magnet bearing magnetic drive pump is characterized in that a rotating shaft 916) of the transmission portion is fixed on the base portion of the array permanent magnet bearing (10). Compared with the prior art, the array permanent magnet bearing magnetic drive pump is reasonable in design and simple in structure, 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 magnetic drive pump technical field, more particularly, belong to a kind of array permanent magnetism bearing magnetic drive pump technology.
Background technique
In prior art permanent magnetism magnetic suspension magnetic drive 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 magnetic drive pump.Therefore consider that novel Permanent Magnet Bearings is applied to magnetic drive pump and has important realistic meaning.
Summary of the invention
The present invention, in order to solve above technical problem, has provided a kind of array permanent magnetism bearing magnetic drive pump.
A kind of array permanent magnetism bearing magnetic drive pump of the present invention, comprises base part, power section, pump housing part and drive part; It is characterized in that: the rotating shaft of described drive part is fixed on base part by array permanent magnetism bearing.
The present invention is compared with prior art: have advantage reasonable in design, simple in structure, to utilize Halbach array permanent magnetism bearing can realize higher rotation speed, without fretting wear, reliable performance, the advantage such as the life-span is long, pollution-free, maintenance load is little.
