Abstract
The utility model discloses an external magnetic rotor having fan blades. The external magnetic rotor having the fan blades comprises an external magnetic cylinder, wherein an inner wall of a front end of the external magnetic cylinder is provided with a ring of external magnetic steel, an inner portion of a back end of the external magnetic cylinder is provided with a shaft sleeve, a plurality of fan blades are connected between an external wall of the shaft sleeve and the inner wall of the external magnetic cylinder, and gaps are arranged among the fan blades. The external magnetic rotor having fan blades guarantees reliable operation of mechanical pump equipment and further settles a disadvantage of obvious reduction of a magnetic couple driving torque because of temperature rising.
Description
Technical field
The utility model relates to magnetic driver and makes the field, is specifically related to a kind of outer magnet rotor with fan blade, is mainly used in the equipment such as fluoroplastics magnetic force driven centrifugal pump, extractor.
Background technology
Magnetic drive pump because of have stationary seal, without the advantages such as leakage, be particularly suitable for carrying the media such as deep-etching, poisonous, inflammable and explosive, precious liquid, be widely used in the industries such as chemical industry, pharmacy, non-ferrous metal.Because the distance of the inside and outside magnet rotor of magnetic force idol is very big on the impact of magnetic drives moment of torsion; so the separation sleeve between inside and outside magnet rotor will be done thinly as far as possible; consider the factors such as pressure-bearing, mechanical strength, corrosion resistant, magnetic force penetrate; separation sleeve is usually used fluoroplastics outer casing stainless steel cover and is made; during work; inside and outside magnet rotor High Rotation Speed between stainless steel sleeve; the metal stainless steel sleeve produces fever phenomenon because cutting magnetic line generates eddy current; eddy-current heating often can cause pump to damage, can not work, and has had a strong impact on the user and has normally used.
The utility model content
The utility model provides a kind of outer magnetic (claiming again to drive magnetic) the driving function of rotor and the heat sinking function of aerofoil fan is combined with the outer magnet rotor of fan blade.
The technical solution adopted in the utility model is:
Outer magnet rotor with fan blade, include outer magnetic cylinder, it is characterized in that: the inwall of the front end of described outer magnetic cylinder is provided with a circle outer steel, the inside of the rear end of described outer magnetic cylinder is provided with an axle sleeve, be connected with a plurality of fan blade between the outer wall of axle sleeve and the inwall of outer magnetic cylinder, between described each fan blade the space arranged.
Described outer magnetic cylinder, outer steel, fan blade, axle sleeve form an integral body by hot investment casting.
Described fan blade is set as spatial warping shape, and its direction of twist is determined according to the direction of rotation of magnetic drive pump.
When prime mover drove outer magnet rotor High Rotation Speed, fan blade will produce high velocity air from back to front, and the stainless steel sleeve between the inside and outside magnet rotor of eddy-current heating and outer magnet rotor are carried out air blast cooling, had taken away rapidly the heat of eddy current generation.
The utility model has the advantages that:
The utility model provides the approach of air blast cooling, has guaranteed the reliability service of pump equipment, has solved simultaneously the drawback that magnetic force idol driving torque Yin Wendu raises and obviously reduces.
Description of drawings
Fig. 1 is cutaway view of the present utility model.
Fig. 2 is vertical view of the present utility model.
Embodiment
As shown in Figure 1, 2, outer magnet rotor with fan blade, include outer magnetic cylinder 1, the inwall of the front end of outer magnetic cylinder 1 is provided with a circle outer steel 2, the inside of the rear end of outer magnetic cylinder 1 is provided with an axle sleeve 4, be connected with a plurality of fan blade 3 between the inwall of the outer wall of axle sleeve 4 and outer magnetic cylinder 1, between each fan blade 3 slit arranged.
Outer magnetic cylinder 1, outer steel 2, fan blade 3, axle sleeve 4 form an integral body by hot investment casting.
When outer magnet rotor is pressed direction rotation shown in Fig. 1 under prime mover drives, just can produce the air blast cooling air-flow that blows to outer steel 2 directions, the large I of air quantity is considered the factor designs such as rotating speed, leaf curling angle according to fluid mechanics and Theories of Cascades.
Claims (3)
1. outer magnet rotor with fan blade, include outer magnetic cylinder, it is characterized in that: the inwall of the front end of described outer magnetic cylinder is provided with a circle outer steel, the inside of the rear end of described outer magnetic cylinder is provided with an axle sleeve, be connected with a plurality of fan blade between the outer wall of axle sleeve and the inwall of outer magnetic cylinder, between described each fan blade the slit arranged.
2. the outer magnet rotor with fan blade according to claim 1 is characterized in that: described outer magnetic cylinder, outer steel, fan blade, axle sleeve form an integral body by hot investment casting.
