Abstract
The utility model discloses a direct driving type magnetic pump, which comprises a pump and a motor, wherein a motor stator is arranged in the motor, the pump comprises an impeller assembly with a permanent magnet, an isolation sleeve connected with a pump case is arranged in the pump case, the impeller assembly of the pump is arranged in the isolation sleeve, the end part of a motor casing is connected with the pump case, and the motor stator is arranged between the isolation sleeve and the pump case. When a device is adopted for making the direct driving type magnetic pump, the manufacture of a driving shaft assembly is avoided, the ordering of a shaft coupler is avoided, only components behind the isolation sleeve are made, only the motor stator (with a fan) is needed, and the components are assembled into the direct driven magnetic pump, so the resources are saved, the energy sources are saved, the equipment components are reduced, and in addition, the damage rate of equipment is reduced.
Description
Technical field
The utility model relates to a kind of pump, relates in particular to a kind of magnetic drive pump.
Background technique
At present, the purposes of magnetic drive pump more and more widely.Because magnetic drive pump does not need mechanical seal, environmental protection requirement is increasingly high at present simultaneously, and the application of magnetic drive pump is more paid attention to.Traditional magnetic drive pump is as shown in Figure 1, comprises motor 1, coupling 2, drive shaft assembly 3, separation sleeve, slide bearing assembly, impeller, spiral case etc., and its movement process produces the rotation of field drives rotor for send electricity when motor stator after; Driving drive shaft assembly 3 through coupling 2 rotates; The embedded permanent magnetic sheet of driven unit when drive shaft assembly turns round, produces the magnetic force of rotation; Drive the impeller assembly running in the separation sleeve, reach the purpose of fed sheet of a media.There is twice magnetic force transmission in traditional magnetic drive pump, once is that motor stator is passed to rotor with magnetic force, once is that drive shaft assembly is delivered to impeller assembly, causes the loss of twice energy; And existence needs the shortcoming of coupling and two parts of drive shaft assembly.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, and a kind of efficient that not only can improve pump is provided, and can reduce cost and energy-conservation a kind of directly driving type magnetic drive pump.
The utility model is achieved through following technological scheme.
A kind of directly driving type magnetic drive pump; It comprises that pump and Qi Nei are equipped with the motor of motor stator; Described pump comprises the impeller assembly that has permanent magnet, and the separation sleeve that links to each other with pump case is installed in described pump case, and the impeller assembly of said pump is installed in the separation sleeve; The shell end of described motor links to each other with the housing of pump, and described motor stator is installed between described separation sleeve and the pump case.
Adopt the utility model device compared with prior art to have following advantage: when making the directly driving type magnetic drive pump; No longer make drive shaft assembly, no longer order coupling and only do the later parts of separation sleeve, only need motor stator (band fan); Assembling becomes the directly driving type magnetic drive pump; Thereby economize on resources, energy saving reduces equipment unit and has reduced the damage probability of equipment.
Description of drawings
Fig. 1 is the structural representation of existing directly driving type magnetic drive pump;
Fig. 2 is the structural representation of a kind of directly driving type magnetic drive pump of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of directly driving type magnetic drive pump like the utility model shown in the drawings; It comprises the motor 1 and pump 4 that motor stator is installed in it, and described pump comprises the impeller assembly that has permanent magnet, in described pump case, separation sleeve is installed; Separation sleeve links to each other with pump case; Impeller assembly is installed in the separation sleeve, and the shell end of described motor links to each other with the housing of pump, and described motor stator is installed between described separation sleeve and the pump case.
This device operation process is following: after the motor stator energising, produce magnetic field, magnetic field acts directly on the permanent magnet of the impeller assembly that has permanent magnet, and drives impeller is rotated (consistent with the running principle of common electric machine), reaches the purpose of fed sheet of a media.
