Abstract
The utility model relates to a wind self-cooling magnetic driver, which is a coupling frame coupled with a motor, wherein a driven shaft is arranged in the coupling frame; an inner magnetic rotor of the magnetic driver can be arranged outside the driven shaft; an inner magnet is arranged on the inner magnetic rotor; an isolating sleeve is arranged outside the inner magnetic rotor. An outer magnetic rotor of the magnetic driver is arranged outside the isolating sleeve; an outer magnet is arranged in the outer magnetic rotor; the outer magnetic rotor is coupled with a motor shaft. The utility model is characterized in that blades can be arranged on the outer magnetic rotor; a ventilating hole is arranged on a supporting plate of the outer magnetic rotor; both ends of the coupling frame have a wind inlet and a wind discharging hole. The blades can be driven to rotate after the motor rotates; air can be sucked in from the right (the wind inlet) of the coupling frame and can be discharged from the left (the wind discharging hole); simultaneously, the outer magnet and the isolating sleeve are cooled, causing that the temperature of the outer magnet is reduced.
Description
Technical field
The utility model relates to magnetic driver, can be widely used in centrifugal pump, Roots vacuum pump etc.
Background technology
In the plant equipment of pressure differential is arranged, for example Roots vacuum pump etc. is owing to run up and mechanical wear, make the mechanical seal parts of pump power power transmission shaft be easier to damage leakage, in case leak and seriously to influence vacuum degree, therefore, people have developed the magnetic driver that can solve the mechanical drive shaft sealing problem.But existing magnetic driver is owing to the effect of eddy current, and the heat that interior magnetic produces is by liquid cools, and outer magnetic heating generation temperature raises, only depend on the natural convection air cooling at present, weak effect, the temperature rising can cause the demagnetization phenomenon, makes magnetic driver lose function of use.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of wind-force self cool magnetic driver that can effectively cool off outer magnet and separation sleeve fast to be provided.
The technical scheme of the utility model wind-force self cool magnetic driver is: the hitch that connects motor is arranged, driven shaft is arranged in the hitch, driven shaft is installed magnet rotor in the magnetic driver outward, on the interior magnet rotor inner magnet is installed, interior magnet rotor has separation sleeve outward, separation sleeve has the outer magnet rotor of magnetic driver outward, in the outer magnet rotor outer magnet is installed, outer magnet rotor connects motor shaft, it is characterized in that on the outer magnet rotor fan blade being installed, be shaped on ventilation hole on the magnet rotor supporting bracket outside, be shaped on fresh air inlet and vent at two of hitch.The technical program drives the fan blade rotation after motor shaft rotates, air sucks from hitch the right (fresh air inlet), and the left side (vent) discharges, and cooled off outer magnet and separation sleeve simultaneously, and the outer magnet temperature is reduced.In order to improve wind-force, the fan blade guide plate is installed in the magnet rotor outside.

Fig. 1 is the utility model wind-force self cool magnetic driver organigram;
Fig. 2 is that this wind-force self cool magnetic driver A-A is to schematic diagram.
Embodiment
The utility model discloses a kind of wind-force self cool magnetic driver, it is the hitch 12 that connects motor 13, driven shaft 1 is installed at the middle part of hitch, driven shaft is installed magnet rotor 5 in the magnetic driver outward, inner magnet 4 is installed on the interior magnet rotor, interior magnet rotor has separation sleeve 3 outward, separation sleeve has the outer magnet rotor 7 of magnetic driver outward, outer magnet 6 is installed in the outer magnet rotor, outer magnet rotor connects motor shaft 11, it is characterized in that fan blade 9 is installed on the outer magnet rotor 7, be shaped on ventilation hole 8 on the magnet rotor supporting bracket outside, be shaped on fresh air inlet 10 and vent 2 at two of hitch 12.And in the magnet rotor 7 fan blade guide plate 14 is installed outside.The rotation of this fan blade 9 is to be driven by the rotation of original motor shaft 11, does not need to put in addition power.The wind-force that the fan blade rotation produces directly enters outside the separation sleeve through the ventilation hole of outer magnet rotor supporting bracket, and outer magnet 6 and separation sleeve 3 are cooled off.Fan blade guide plate 14 has been arranged, and cooling effect is better.
