Description
Technical field
The present invention relates to the Pumps ﹠ Fans technology, particularly a kind of axial-flow pump machine with suspended propeller.
Background technique
Traditional pump or fan, motor are two kinds of separate equipment, and coupling commonly used is linked together work.As Fig. 1, the structural representation that is linked together for a kind of existing bent-tube boiler axial flow pump or fan and motor.The axial flow pump or fan is made up of impeller 1, support 2, bearing 3, curved pipe 4, axle 5, bearing 6, and the axial flow pump or fan is linked together with coupling 7 and motor 8.This pump or fan is at pipeline 4 domestic demand mounting brackets 2, and support 2 and axle 5 convection cells have no small resistance, thereby efficient is not high; Need sealing at bearing 6 places, this sealing is dynamic seal (packing), and the friction of the axle 5 that Sealing is rotated was easily lost efficacy and caused leakage.
As Fig. 2, be the schematic representation of the axial flow pump or fan of another kind of existing conventional.Impeller 9 is directly installed on the axle of motor 12, uses support 11 support fixation motors in straight pipeline 10.Because of the external diameter of motor 12 is bigger than the diameter of the axle 5 of preceding a kind of pump or fan, so the resistance of the support 11 of this pump or fan and motor 12 convection cells is bigger, efficient is lower.
Summary of the invention
The present invention designs a kind of axial-flow pump machine with suspended propeller, is intended to overcome the above-mentioned defective of existing axial flow pump or fan, utilizes permanent magnetism power to make impeller suspended, utilizes electromagnetic energy and permanent magnetism to drive, and realizes efficient, energy-conservation.
The present invention realizes by following technological scheme.
The present invention is made of stator, rotor, control system; Permanent-magnetic clamp is set on rotor, rotor is suspended among the stator; At the fixed annulus that some permanent magnetism magnetic poles are arranged of the impeller periphery of 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 sensor, and (visualizer is the hardware of estimation rotor-position and velocity information and the abbreviation that comprises algorithm, and visualizer 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 system of coordinates with respect to the position signal of stator tooth or visualizer.Visualizer has mature technique.As sliding mode observer etc.) determine the position signal 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, thereby drives impeller, and driving the generator for electricity generation of described motor, the electricity that sends deposits storage battery in through rectification voltage regulator.
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 working 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 present invention 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 invention is greater than the electric energy of need input.Square being directly proportional of magnetic induction intensity between the electromagnetic pole of the motor stator of motor of the present invention and the rotor permanent-magnet pole in amount of force and the gap between them, and the superposition value that this magnetic induction intensity value is electromagnetic pole and permanent-magnet pole magnetic induction intensity, if keep this value constant, improve the magnetic induction intensity value of permanent-magnet pole in described gap, reduce the magnetic induction intensity 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 present invention 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 impeller, 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 invention and working 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 invention 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 invention 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 motor of the present invention 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 hysteresis loss in rotor core.And the magnetic line of force that the stator field of motor of the present invention enters rotor is seldom, in rotor induction very weak, so the present invention is energy-conservation significant more than magneto.
For fear of flowing through fluid in the described axial-flow pump machine with suspended propeller, can beat the non magnetic insulated enclosure cylinder of lining at the inwall of stator to the internal corrosion or the wearing and tearing of pump machine stator.
The present invention is a pump, is again blower fan, can do separately pump with or make blower fan usefulness separately, can be as the propulsion device of ship and aircraft; If stator coil is all received rectification voltage regulator, the present invention is exactly wind-driven generator or hydraulic turbine generator or steam turbine generator.
The present invention has following advantage:
1, because impeller suspended in stator, does not need bearing, support, thereby avoided the resistance of convection cell, avoided extra energy loss;
2, since impeller suspended in stator, thereby exempt to lubricate, vibrate little, noise is little, the life-span is long;
3, 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 power consumption of the present invention seldom, and loss is little, and is energy-conservation, and efficient is high, and operating cost is very low;
4, the present invention produces power and drives impeller occurs in described control system and rotor simultaneously, and has only movement parts of rotor, and volume is little, and is simple and compact for structure, so reliability is very high, and low cost of manufacture;
5, sealing does not fully have and leaks environmental protection.
