Abstract
A magnetic force pump technology for solving the technical disadvantage that weak pressure-bearing capability of the nonmetal material spacer sleeve affects operation of the magnetic force pump. The magnetic force pump provided by this utility model comprises a pump casing, a pump shaft disposed axially inside the pump casing, a pump shaft impeller, a sliding bearing mechanism of the pump shaft, a pump shaft magnet driven rotor and a motor output shaft magnet driving rotor. Wherein the motor output shaft magnet driving rotor is inner magnet rotor and the pump shaft magnet driven rotor is outer magnet rotor, which are disposed inside and outside the spacer sleeve correspondingly. The spacer sleeve port edge is fixed on the pump casing. The technical scheme changes disposing direction of the spacer sleeve, thereby increases its pressure-bearing capability and anti-deformation capability, adopts nonmetal material spacer sleeve to solve vortex temperature rising, and creates conditions for highly reliable operation.
Description
Technical field
The utility model relates to the magnetic drive pump technology.
Background technique
The agent structure of existing magnetic drive pump constitutes: the magnetic driving mechanism, pump shaft impeller and the bearings mechanism that are made of magnet rotor in outer magnet rotor of the motor shaft in the pump housing and the pump shaft constitute jointly, be provided with separation sleeve between its China and foreign countries magnet rotor and interior magnet rotor, interior magnet rotor be provided with the space with outer magnet rotor separated by spaces be set and come.The technical problem underlying that this product structure exists is: its separation sleeve works in the interior high temperature rise environment of pump, also to bear the big pumping pressure that comes from pumped medium, separation sleeve expands, distortion is unavoidable, and directly influences reliable, the safe operation of magnetic drive part.For solving this technical problem, Chinese patent CN200420002447.4, name are called the patented technology scheme of " plastics magnetic drive pump ", make separation sleeve by fiber-reinforced resin, and are provided with the metal strengthening net.Though this technological scheme has improved separation sleeve resistance to high temperature and corrosion resistance, owing to fundamentally do not change the bearing structure of separation sleeve, so that its technique effect that reaches is still is extremely limited.
The model utility content
Thereby goal of the invention of the present utility model is to provide a kind of makes separation sleeve have reliable pressure ability to bear structure so that adopt non-metallic material to make the magnetic drive pump that separation sleeve is eliminated its eddy current temperature rise.Magnetic drive pump technological scheme of the present utility model, its major technique content is: a kind of magnetic drive pump, its structure includes pump case, pump case axially is provided with sliding bearing mechanism, pump shaft magnetic driven rotor and the motor output shaft magnetic power rotor of pump shaft, pump shaft impeller, pump shaft, the technical characterstic of the technical program is that its motor output shaft magnetic power rotor is interior magnet rotor, its pump shaft magnetic driven rotor is outer magnet rotor, interior magnetic power rotor is corresponding with outer magnetic driven rotor to be arranged at inside and outside the separation sleeve, and its separation sleeve running-on edge is fixed in pump case and constitutes.
Magnetic drive pump technological scheme of the present utility model, by changing the structure that is oppositely arranged of outer magnet rotor and interior magnet rotor, change the direction that fixedly installs of separation sleeve, thereby made full use of the bearing capacity of high pressure-bearing position that separation sleeve self possessed realizing improving separation sleeve with and the technical purpose of non-deformability, thereby for avoiding the eddy current temperature rise to adopt the nonmetallic material separation sleeves, realizing that the reliable operation of magnetic drive pump created condition.In addition, this structure has also been simplified the structure that fixedly installs of separation sleeve.
Description of drawings
Accompanying drawing 1 is looked the sectional structure schematic representation for the master of the utility model magnetic drive pump.
Embodiment
As shown in the figure, magnetic drive pump of the present utility model, include the pump case that constitutes by the pump housing 1 and pump hitch 2, the pump housing 1 inner relative pump cover 3 that is mainly used in sliding bearing 40 support structure pump shafts 4 that is provided with the pump housing, pump chamber one end of pump shaft 4 is provided with impeller 41, the other end is provided with magnetic driven rotor 42, drives the magnetic power rotor cooperate 5 with magnetic driven rotor 42 magnetic and is arranged on the motor output shaft by coupling.The magnetic power rotor 5 of its motor output shaft is interior magnet rotor, its pump shaft magnetic driven rotor 42 is outer magnet rotor, between interior magnet rotor and the outer magnet rotor separation sleeve 6 is set, magnetic power rotor 5 as interior magnet rotor places in the separation sleeve 6, magnetic driven rotor as outer magnet rotor places outside the separation sleeve 6 corresponding to interior magnet rotor, the curved end 60 of separation sleeve 6 is provided with respect to the cool cycles inner chamber 30 of the outer magnet rotor of pump shaft, and separation sleeve running-on edge 61 is fixed on the projecting inward side end face 20 of pump hitch 2.Be the eddy current temperature rise of avoiding magnetic drive pump separation sleeve 6 in service to produce, this separation sleeve adopts nonmetallic material to make.
