Abstract
The invention relates to a motor with a leak-proof isolation hood. The motor comprises a motor shell, a rotor, a stator and a transmission shaft, wherein the stator is arranged in the motor shell, and the rotor is fixed on the transmission shaft. The motor is characterized in that: the leak-proof isolation hood is fixedly arranged in the motor shell through an isolation hood flange, and the leak-proof isolation hood is isolated between the rotor and the stator. The motor overcomes the defect that the mechanical seal of the conventional sailing thruster and the conventional stirring reaction kettle or the conventional chemical pump is easy to leak, overcomes the limitation of torque force and transmission speed of a magnetic transmission device, and reduces the manufacturing cost. The motor provides possibility for trial manufacture and manufacture of special equipment with strict process requirements, provides multiple choices for tooling equipment, reduces the equipment running noise and saves the manufacturing cost.
Description
Technical field
The present invention relates to a kind of motor, especially a kind of motor that has the anti-leak cage.
Background technology
At present, the rotation of known navigation device, stirring-type reactor or chemical pump all is a drive of motor, and revealing appears in its mechanical seal meeting; Currently be regarded as comparatively advanced magnetic drive device, also have the limitation of torsional forces, transmission speed.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of leakage problem that has not only solved the rotary seal of navigation device and stirring-type reactor or chemical pump is provided, and has solved the motor that have anti-leak cage of magnetic drive device in limitation aspect torsional forces, the transmission speed.
According to technical scheme provided by the invention, the described motor that has the anti-leak cage, comprise motor casing, rotor, stator and power transmission shaft, rotor rotation is installed in the motor casing, rotor is fixed on the power transmission shaft, stator is fixed on the motor casing, and feature is: be installed with the anti-leak cage by the cage flange in motor casing, described anti-leak cage is every between rotor and stator.
Described rotor exterior is enclosed with protective layer.Described protective layer is moulded by fluorine or macromolecular material is made.
The present invention not only overcomes the easy deficiency of revealing of mechanical seal of existing navigation propeller and stirring-type reactor or chemical pump, and has overcome the torsional forces that magnetic drive device exists, the limitation of transmission speed, also in order to reduce manufacturing cost.Motor of the present invention provides possibility for the special installation trial-production and the manufacturing that require harshness on the technology, and the multinomial selection of tooling device is provided, and has reduced the equipment operation noise and saved manufacturing cost.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention mainly is made of parts such as anti-leak cage 1, rotor 2, stator 3, protective layer 4, power transmission shaft 5, cage flange 6 and motor casings 7.
This has the motor of anti-leak cage, comprise motor casing 7, rotor 2, stator 3 and power transmission shaft 5, stator 3 is installed in the motor casing 7, rotor 2 is fixed on the power transmission shaft 5, be installed with anti-leak cage 1 by cage flange 6 in motor casing 7, described anti-leak cage 1 is every between rotor 2 and stator 3.
Described anti-leak cage 1 is by the metal or the nonmetallic materials of shielding magnetic are not made.
At rotor 2 outer wrap matcoveredns 4.Described protective layer 4 is moulded by fluorine or macromolecular material is made.
The present invention is installed in stator 3 outside the anti-leak cage 1, and rotor 2 is installed within the anti-leak cage 1, and anti-leak cage 1 is with the metal or the nonmetallic materials of armoured magnetic field are not made; Cage flange 6 is connected with stirring-type reactor or chemical pump, constitutes an airtight space.Produce rotating magnetic field after stator 3 energized, the rotor 2 in the anti-leak cage 1 transfers out moment of torsion at the effect backspin of electromagnetic field, directly drives the shaft or the pump shaft rotation of reactor.
Because this rotor that has the anti-leak cage is to adopt squirrel-cage or magneto, its operation principle is equal to common AC asynchronous motor, can obtain very big starting torque when loaded starting.The problem of moment of torsion deficiency when the invention solves present existing magnetic drive device because of the constant loaded starting that causes of moment of torsion.Because this rotor 2 that has anti-leak cage 1 is to move, thoroughly solved the leakage problem that stirring-type reactor, navigation device or chemical pump cause because of mechanical rotation again in confined space.And because the rotor top layer can matcoveredn, protective layer 4 can be that fluorine is moulded or other macromolecular materials, so can solve the etching problem of medium to rotor effectively.
The lower end of anti-leak cage 1 is the type of attachment of cage flange 6, can link to each other in reactor or chemical pump, make motor at stator 3 with among rotor 2 is in different media environments.Rotor 2 transfers out moment of torsion at the effect backspin of electromagnetic field after stator 3 energized, directly drives the shaft or the pump shaft rotation of reactor.Rotor can prevent to be corroded by container inner medium by matcoveredn 4.
