Description
Technical field
The present invention relates to the unidirectional magneto formula of a kind of interchange water pump, relate in particular to a kind of traditional motor with cup rotor, induction machine etc. given up, adopt the water pump that exchanges unidirectional magneto.
Background technique
At present, traditional water pump is because the narrow limitation on structure and principle generally all is used a pump cover with a pump housing, and the same pump housing can not be used the pump cover of different structure instead, and perhaps the pump housing can not break away from pump cover and use separately; Simultaneously; Being provided with the motor driving wheel rotation in the pump housing, often all is to adopt impeller to be mounted on the installation form in the pump housing, when needs clean impeller demolition; After need dismantling other component in the pump housing one by one; Could dismantle impeller, like this, clean, install, dismantle just comparatively trouble and inconvenience of impeller; In addition, traditional motor that water pump adopted generally all is motor with cup rotor or induction machine, and the shortcoming of motor with cup rotor is that efficient is low big with slippage, causes motor dirty stifled easily; And the shortcoming of induction machine is that power factor lags behind, the underloading power factor is low, speed adjusting performance difference etc.These two kinds of motor application stability and efficient to water pump on water pump has certain reduction, influences the working life of water pump.
Hall transducer is a kind of magnetoelectric transducer based on Hall effect, be a kind of when alternating magnetic field through the sensor of out-of-date generation output voltage pulse, the amplitude of pulse is that therefore, Hall transducer does not need extraneous power supply power supply by the field intensity decision of excitation field.Hall transducer is because semiconductor has much higher Hall coefficient than metal, so the Hall transducer of processing with semiconductor has characteristics such as the magnetic-field-sensitive degree are high, simple in structure, easy to use; Not only be used to measure electromagnetic parameters such as electric current, voltage, power and magnetic induction intensity, in non-electrical quantity measuring technology, also be widely used in non electrical quantities such as measuring straight-line displacement, angular displacement and pressure.Hall transducer is a kind of good detection control unit, and when the control electric current was constant, the voltage of Hall output was directly proportional with the magnetic field size, can be used to determination sensor magnetic field on every side.When magnetic intensity fixedly the time, then can measure the electricity ginsengs such as electric current, voltage of Hall plate.The product that utilizes hall electromotive force to control electric current and magnetic field size then can be made into various arithmetic mean unit.To Non-Electricity Measurement then is to change parameter α through changing the position of Hall plate in magnetic field, comes Displacement Measurement, pressure, acceleration etc. thereby change the output hall electromotive force.
Therefore, Hall transducer is applied in more and more widely and is used to measure electromagnetic parameters such as electric current, voltage, power and magnetic induction intensity etc. on the existing water pump.But,, between Hall transducer and the circuit board inseparable relation is arranged because existing Hall transducer is installed separately with the circuit board that is installed in the water pump.Can produce great amount of heat energy when some elements are worked on the circuit board, can influence it when overheated and use, so circuit board need be installed in the position near the water pump water-cooled, so that the transmission of heat.Because the mounting point of Hall transducer is closely bound up with the working efficiency of water pump, good and the bad direct starting and the efficient that influences water pump of Hall transducer mounting point.Being installed separately of Hall transducer and circuit board, the heat that circuit board gave out can be delivered to Hall transducer, influences the measured data of Hall transducer.
Summary of the invention
The objective of the invention is to solve the existing defective of water pump in the existing technology, a kind of water pump that exchanges unidirectional magneto that adopts is provided, give up employed motor with cup rotor of traditional water pump or induction machine, solve this two kinds of existing defectives of motor; Also solve simultaneously existing Hall transducer of water pump and the existing problem of circuit board in the existing technology.
The technical solution adopted for the present invention to solve the technical problems is: the unidirectional magneto formula of a kind of interchange water pump; The impeller that comprises the motor that is provided with in the pump housing, the pump housing, drives by rotor, bonnet, water intake and the water outlet at capping pump housing rear portion; Wherein aforesaid motor adopts and exchanges unidirectional magneto; Water-cooled position near motor in the pump housing is provided with the circuit board of controlling motor action, and circuit board is provided with Hall transducer, and Hall transducer and circuit board become one.The characteristics that exchange unidirectional magneto are: simple in structure, volume is little, in light weight, loss is little, efficient is high.Exchange unidirectional magneto owing to there is not rotor current, rotor loss is very little; It does not need idle field current, and power factor is high, and stator current and stator loss reduce, and therefore, exchange unidirectional magneto overall efficiency than the high 5%-10% of induction machine.In addition, the comparable induction machine of ratio of maximum output torque and rotor inertia that exchanges unidirectional magneto is a lot of greatly, and it is superior therefore to exchange unidirectional magneto dynamic performance, fits the servocontrol motor of what as highi degree of accuracy, high dynamic performance.So water pump of the present invention is given up the employed motor with cup rotor of water pump and the induction machine of existing technology, can solve this two kinds of existing defectives of motor, guarantee the proper functioning and the working life of water pump.In addition, simple, the advantages of small volume of board structure of circuit of the present invention, with Hall transducer become one the back directly install insert in the pump housing after, need not to install separately again Hall transducer, simple and efficient, install simple; Because can produce great amount of heat energy during the work of some elements on the circuit board, can influence its protection and use when overheated, so circuit board need be installed in the position near the water pump water-cooled; Simultaneously, circuit board and Hall transducer are installed together, and can not make the heat transferred Hall transducer circuit board and Hall transducer remain at the normal temperature state during circuit board heat radiation, guarantee the proper functioning of circuit board and Hall transducer.The heat-conducting resin of filling in the water pump can have enoughly very much drains the heat that circuit board distributed, and improves the working efficiency of water pump greatly.
As the further design to the aforementioned techniques scheme: the position of mounting circuit boards is provided with the Hall installation fixing position that makes the Hall transducer mounting point fixing in the aforesaid pump housing.Hall installation fixing position order is each can to install to same place when Hall transducer is installed with circuit board, makes the installation of circuit board and Hall transducer can both be fast and convenient, and one goes on foot in placely, directly inserts the interior Hall installation fixing position of the pump housing and gets final product.
