Description
Affiliated technical field
The utility model relates to a kind of magnetic drive pump, specifically relates to the magnetic transmission structure of driven pump.
Background technique
The magnetic drive pump of prior art generally all is the rotatingshaft that Motor torque is sent to pump by magnetic coupling, between the inside and outside magnet rotor of magnetic coupling, there is spacer that electric motor drive parts external rotor and pump drive parts internal rotor are separated, simultaneously the pump drive part sealed again.Because working medium and interior magnet rotor separation sleeve are in together in the chamber during pump running, interior magnet rotor magnetic is easily degenerated, for magnetic is rotated effectively, the thickness of separation sleeve is generally about 2-4mm, energy proper functioning in common medium, but in special trades such as light fluorine acid, wireless, plating, this pump can not normally use.
Summary of the invention
In order to overcome the shortcoming that prior art exists, the utility model provides a kind of high temperature resistant, anticorrosive, lining NEOFLON FEP resin magnetic force driving pump that moulding is excellent, safe and reliable.
The technical solution of the utility model is: comprise that mainly motor is connected in outer magnet coupler, separation sleeve and bearing support are fixed on the support respectively, interior magnet rotor is fixed on the axle, bearing is separately fixed at that retainer shaft is steady state of motion on bearing support and the separation sleeve, impeller is fixed on the axle by impeller nut, described bearing support is provided with vent, the axle center is provided with pod apertures, the axle center is provided with the interior pod apertures of lubrication hole and bearing and cooperates, impeller nut is provided with conduction hole and communicates with the pod apertures at axle center, and impeller is provided with rotating ring and cooperates with the stationary ring that the pump housing is provided with.
The pump housing, impeller, bearing support, the impeller nut at this magneto drive type pump institute contact liq position is the compression molding of lining NEOFLON FEP resin (PFA) material, have excellent moldability, incombustibility, under high temperature and low temperature environment, has reliable Security, excellent electric performance, chemicals had excellent repellence, be exposed to the open air for a long time and also do not change its mechanical property, its surperficial friction ractor is low, and heatproof is 200 ℃--between 200 ℃;
Other component of this pump such as axle sleeve, lining, axle, dynamic and static ring all adopt the silicon carbide material thermal sintering, it adapts to various media and high and low temperature, have characteristics such as not easy to wear, indeformable, not oxidation, strong alkali-acid resistance, solved because axle sleeve, lining, axle, dynamic and static ring damage influence the pump drawback in working life;
This pump work medium does not directly contact with interior magnet rotor, because lining NEOFLON FEP resin, high temperature resistant and low temperature resistant, use magnetic force not degenerate for a long time, solved because pump uses for a long time and produced the drawback that high temperature causes interior magnet rotor magnetic degradation effects pump capacity and lift.
This pump casing adopts the precision stainless steel casting, has characteristics such as indeformable, high temperature resistant, corrosion-resistant;
The magneto drive of this pump partly adopts high-strength magnetic, NdFEB magnet (Nd-Fe-B magnetic pole) and China fir cobalt permanent magnet to make, and has characteristics such as high temperature resistant, long-time use is not demagnetized, magnetic is strong, guarantees pump duty and lift.
