The magnetic transmission centrifugal pump is simple and reasonable in structure and is supported by two ends of the shaft, so that the magnetic transmission centrifugal pump is stable and reliable in operation, the common engineering plastics are replaced by specific engineering plastics such as fluoroplastics, the comprehensive performance is high, the long-term service temperature is about 150 DEG C, and according to a magnetic part, a ferrite magnetic material is replaced by strong magnetic materials such as neodymium iron boron and samarium cobalt, so that the magnetic transmission centrifugal pump is compact in structure, attractive in appearance, small in volume and low in noise.
Description
Technical field
The utility model relates to a kind of centrifugal pump, particularly a kind of magnetic drive centrifugal pump.
Background technique
That magnetic drive centrifugal pump has is hermetically sealed, do not have leak, pollution-free, vibration is little and noise is low distinguishing feature, be used to carry the liquid that oils, acid, alkali etc. are inflammable, explosive, be prone to befouling environment in a large number, to guarantee the cleaning of production safety and environment.The pump shaft of existing small-sized magnetic drive centrifugal pump adopts cantilever structure, and pump shaft is for filling F4 bag core (No. 45 steel) design, and with spacer be one; Not only processing technology is complicated; And galloping, working life is short, usually uses one or two month pump shaft to rupture; Parts such as the pump housing mostly adopt the unskilled labor engineering plastics, and decay resistance is low, are not suitable for the conveying of some strong acid, highly basic liquid; The magnetic transmission part adopts ferrite, and magnetic property is low, and moment of torsion is little, and is bulky.
The model utility content
The utility model technical problem to be solved is, overcomes the defective that existing technology exists, and provides a kind of and turns round steadily, the life-span is long, can carry strong acid and strong base liquid, compact structure, beautiful shape, volume is little, noise is low magnetic drive centrifugal pump.
The utility model addresses the above problem the technological scheme that is adopted: this magnetic drive centrifugal pump, comprise the pump housing, pump shaft, impeller, magnetic coupling, support and drive motor, and the pump housing has pump inlet; It is characterized in that: said magnetic coupling comprises outer magnet rotor, interior magnet rotor and non-magnetic separation sleeve; Separation sleeve is fixedly connected with the pump housing, and the output shaft of outer magnet rotor and drive motor is connected, and interior magnet rotor is located in the separation sleeve; Interior magnet rotor internal fixation has axle sleeve; Axle sleeve is enclosed within on the pump shaft, and an end of pump shaft is supported on the pump housing, and the other end of pump shaft passes through bearings on separation sleeve.
Magnet rotor comprised magnetic part and serves as a contrast the lining plastomer of moulding in the magnetic part outside in the utility model was described, and described impeller is an integral structure with the lining plastomer.
The material of described pump shaft of the utility model and axle sleeve is a pottery.Because stupalith has advantages such as self lubricity, friction ractor are little, thereby improved the working life of pump greatly.
The material of magnetic part is neodymium iron boron or SmCo in described outer magnet rotor of the utility model and the interior magnet rotor.
The material of the described pump housing of the utility model, separation sleeve, lining plastomer and impeller all is a perfluoroethylene-propylene.
The utility model compared with prior art has the following advantages: simple and reasonable, the two end supports of employing axle makes operation more steadily, reliably; Adopt the special engineering plastics fluoroplastic to replace the unskilled labor engineering plastics, comprehensive higher, long-term serviceability temperature is about 150 ℃; Magnetic part replaces the ferrite magnetic material with ferromagnetic material neodymium iron boron, SmCo, makes compact structure, beautiful shape; Volume is little, and noise is low.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1, the present embodiment magnetic drive centrifugal pump comprises the pump housing 1, pump shaft 2, impeller 3, magnetic coupling, support 4 and drive motor 5; Magnetic coupling comprises outer magnet rotor 6, interior magnet rotor 7 and non-magnetic separation sleeve 8, and separation sleeve 8 is fixedly connected with the pump housing 1, and the output shaft of outer magnet rotor 6 and drive motor 5 is connected; Interior magnet rotor 7 is located in the separation sleeve 8; Interior magnet rotor 7 internal fixation have axle sleeve 9, and axle sleeve 9 is enclosed within on the pump shaft 2, and an end of pump shaft 2 is supported on the pump housing 1; The other end of pump shaft 2 is supported on the separation sleeve 8 through bearing 10, and the pump housing 1 has pump inlet 11.Interior magnet rotor 7 comprises magnetic part and serves as a contrast to mould at the outside lining of magnetic part to be moulded
Body, impeller 3 is an integral structure with the lining plastomer.
The material of present embodiment pump shaft 2 and axle sleeve 9 is a pottery.The material of magnetic part is neodymium iron boron or SmCo in outer magnet rotor 6 and the interior magnet rotor 7.The material of the pump housing 1, separation sleeve 8, lining plastomer and impeller 3 all is a perfluoroethylene-propylene.
During present embodiment work, when magnet rotor 6 turned round outside drive motor 5 drives, magnetic field was through air clearance and separation sleeve 8, and magnet rotor 7 rotates synchronously in driving, thus impeller 3 work.
Present embodiment adopts the two end supports of pump shaft 2; Make operation more steadily, reliably; Impeller 3 is global design and integral plastic lined forming with interior magnet rotor 7, and the axle sleeve 9 of pottery is housed in interior magnet rotor 7 endoporus, and it is secondary that the axle sleeve 9 of pottery and the pump shaft of stupalith 2 form a moving static friction; Because stupalith has advantages such as self lubricity, friction ractor are little, thereby improved the working life of magnetic drive centrifugal pump greatly.
