Abstract
The utility model discloses a magnetic drive pump. A support is arranged between a pump body and a motor; the upper end of the support is connected with a motor shell, and the lower end is arranged on the pump body; a motor shaft penetrates through a support cavity, enters the pump body and then is connected with an impeller in the pump body; the motor shaft in the motor shell is provided with an inner magnetic rotor, outside which an outer magnetic rotor is arranged; and a cylindrical ceramic isolating sleeve is arranged between the inner magnetic rotor and the outer magnetic rotor, and the opening end of the isolating sleeve is connected with the upper end of the support. The surface of the impeller and the inner walls of the pump body and the support are respectively coated with a teflon protective layer. The magnetic drive pump realizes the functions of resisting corrosion and high temperature, prolonging the service life and facilitating maintenance.
Description
Technical field
The utility model relates to a kind of magnetic drive pump.
Background technique
Existing magnetic drive pump majority is a straight connection type; the pump shaft of the magnetic drive pump of this structure is mounted in the two ends of pump case and separation sleeve; magnetic drive pump is when work; the rising of temperature and the increasing of pressure in the pump case; usually can cause the separation sleeve distortion; magnet rotor and outer magnet rotor collision, friction cause separation sleeve, interior magnet rotor, outer magnet rotor to damage, and then magnetic drive pump can't be worked in making.When component such as separation sleeve, interior magnet rotor, outer magnet rotor occur to damage, need repairing, when changing, existing magnetic drive pump need be pulled down motor or relevant pipeline, and this makes to maintenance of existing magnetic drive pump very inconvenient.In addition, the serviceability temperature of existing magnetic drive pump generally can not surpass 80 degree.
The model utility content
The purpose of this utility model is to provide a kind of corrosion-resistant, high temperature resistant, long service life, magnetic drive pump easy to maintenance.
The technical solution of the utility model is: a kind of magnetic drive pump, comprise the pump housing, motor, motor shaft, impeller, separation sleeve, interior magnet rotor, outer magnet rotor, it is characterized in that: between the pump housing and motor, establish a bearing, the bearing upper end connects motor housing, the lower end is installed on the pump housing, motor shaft passes the bearing cavity and enters the pump housing, and connects the impeller in the pump housing; Magnet rotor in installing on the motor shaft in the motor housing, its outside is outer magnet rotor, establishes the cylinder-shaped ceramic separation sleeve between interior magnet rotor, the outer magnet rotor, the separation sleeve opening end is connected with the bearing upper end.
Described impeller surface applies one deck Teflon protective coating.
The described pump housing and bearing inwall apply one deck Teflon protective coating.
The beneficial effects of the utility model are: impeller, the pump housing and bearing inwall apply the Teflon protective coating, separation sleeve adopts stupalith to make, the performance anticorrosive, high temperature resistant, resistance to deformation of pump is increased substantially, bump, rub and cause the possibility of damage thereby reduced between component, can be when 150 spend trouble free service.If damaging appears in component, need repairing, when changing, only need pull down bearing and get final product, this feasible maintenance to magnetic drive pump becomes very convenient.
