Description
Technical field
The utility model relates to electromechanical integration technology, particularly a kind of magnetic energy seal driver.
Background technology
The rotating shaft of device such as traditional pump, valve, reactor and the sealing between the housing realize with the rotating shaft of static seals double team, are dynamic seal (packing)s, and fluid wherein can leak into the outside unavoidably.Magnetic drive is applied to such as pump, valve, reactor etc., it can be modified into hermeticly, and the fluid of thoroughly stopping to flow through wherein outwards drips, emits, oozes, leaks, thereby increases the service life, and economizes on resources, and brings bigger economic benefit and environmental benefit.Yet there is defective in existing hermetically sealed magnetic drive, thereby application is restricted.Be made up of the pump housing, magnetic drive, magnetic drive support, shaft coupling, motor (or driving machine) such as existing hermetically sealed magnetic drive pump, this pump is bigger than conventional pump complex structure, the volume be made up of the pump housing, shaft coupling and motor, efficient is low, cost is high.Also there are similar defective in existing hermetically sealed magnetic drive valve, reactor etc.
Summary of the invention
The utility model designs a kind of magnetic energy seal driver, overcomes the defective of existing magnetic drive, utilizes electromagnetic energy and permanent magnetism can drive, and energy simplified structure, reduced volume, reduces cost, and realizes efficient, energy-conservation.Thereby purposes is wide.
The utility model is realized by following technical scheme.
The utility model is made of stator, rotor, control system, cooling fan; Rotor is got in touch with bearing, and rotor is sealed among the stator fully, armature spindle head erector workpiece (as driving wheel, rotor plate etc.); Some permanent magnetism magnetic poles are arranged on rotor, some teeth that the foreskin coil surrounds that are insulated are arranged on the stator, form electromagnetic pole, described rotor and control system constitute a kind of special machines, it has motor and generator, control system is by rotor-position sensor, controller, storage battery and rectification voltage regulator are formed, controller measures rotor magnetic pole according to transducer, and (observer is the hardware of estimation rotor-position and velocity information and the abbreviation that comprises algorithm, and observer estimates described rotor-position and speed according to electric current in the described stator coils of motor of input and voltage at the component of setting under the coordinate system with respect to the position signalling of stator tooth or observer.Observer has mature technique.As sliding mode observer etc.) determine the position signalling of rotor magnetic pole with respect to the motor stator tooth, respectively organizing coil for motor stator from the storage battery power taking switches on regularly, then rotor be subjected to because of its permanent-magnet pole the motor stator tooth electromagnetic pole attraction moment and repel moment and rotate, and driving the generator for electricity generation of described motor, the electricity that sends deposits storage battery in through rectification voltage regulator.Drive cooling fan with the magnetic transmission.
Suppose the rotor that the permanent magnetism magnetic pole of the rotor of the motor portion of described motor is made plurality of teeth with pure soft iron is replaced, its operation principle is very similar to switched reluctance machines so, disregard loss, the electric energy that switched reluctance machines output energy equals to import, not energy-conservation.And the utility model makes the rotor permanent-magnet pole obtain the repulsion square that electromagnetic pole of corresponding motor stator attracts moment and another electromagnetic pole simultaneously, and gravitation square or repulsion square provide jointly by electromagnetic field and permanent magnetic field; Switched reluctance machines only is the soft iron tooth of its rotor of electromagnetic attracting force of stator tooth, and this gravitation is only provided by electromagnetic field.So the motor output energy of motor of the present utility model is greater than the electric energy of need input.Square being directly proportional of magnetic flux density between the electromagnetic pole of the motor stator of motor of the present utility model and the rotor permanent-magnet pole in amount of force and the gap between them, and the superposition value that this magnetic flux density value is electromagnetic pole and permanent-magnet pole magnetic flux density, if keep this value constant, improve the magnetic flux density value of permanent-magnet pole in described gap, reduce the magnetic flux density value of electromagnetic pole in described gap equally, then described motor machine output energy value is constant, but reduced the electric energy of required input significantly, energy output input difference becomes big in other words.So the ingenious use permanent magnetism of the utility model physical efficiency, make energy increment, and increment increases substantially with the enhancing of permanent magnetic field, most of outwards output of this value-added energy drives described driving wheel, fraction is used for described generator for electricity generation, to support described motor operation.
It should still be noted that, electric motor structure of the present utility model and operation principle and magneto (detail knowledge can with reference to interrelated data) have substantial different, magneto utilizes the rotary electromagnetic field of stator to interact with the rotor field of containing permanent magnet and drives rotor, be based on electromagnetic induction principle, and motor of the present utility model is based on gravitation between electromagnet and the permanent magnet and repulsion.Permanent magnet motor stator electromagnetic force and rotor permanent magnetism power are big not as of the present utility model to the torque that its rotor produces, reason is that this stator electromagnetic force only produces the gravitation square to rotor, and the rotor permanent-magnet pole of the utility model motor is subjected to the attraction moment and the repulsion moment of the electromagnetic pole of corresponding stator tooth simultaneously.The rotary electromagnetic field of permanent magnet motor stator can induce eddy current and cause energy loss in rotor core and permanent magnet, and eddy current gives birth to heat and work the mischief, and rotary electromagnetic field also can produce magnetic hysteresis loss in rotor core.And the magnetic line of force that the stator field of the utility model motor enters rotor is seldom, in rotor induction very weak, so the utility model is energy-conservation significant more than magneto.
For fear of internal corrosion or the wearing and tearing of fluid, can beat the non magnetic insulated enclosure cylinder of lining at the inwall of stator to the magnetic energy seal driver stator.
If the utility model stator coil is all received rectification voltage regulator, when rotor of the present utility model is driven by external force, the utility model is exactly a generator.
The utility model has following advantage:
1. because the utility model is designed to one with described work package and their drive motors, the axle that has saved magnetic drive in existing hermetically sealed magnetic drive pump, hermetically sealed magnetic drive valve, the hermetically sealed magnetic transmission reactor, magnetic drive support, shaft coupling, drive motors, thereby the utility model is simple in structure, volume is little, material is cheap, good manufacturability, easily assembling, so the utility model cost is low.
2, fully permanent magnetism can be converted to the directly mechanical energy of actual use, the energy that permanent magnetism can be exported significantly rises in value than the energy of importing, thereby the utility model power consumption seldom, and loss is little, and is energy-conservation, and efficient is high, and operating cost is very low;
3, sealing does not fully have and leaks environmental protection.
