Description
Technical field
The present invention relates to the water pump that a kind of automobile cooling system is used, particularly a kind of automobile cooling water pump that adopts the magnetic transferring power, can work according to the operating mode of motor.
Background technique
Car engine cooling system is to guarantee motor car engine cooling, the requisite system of automobile normal running, existing car engine cooling system generally drives water cycle by common water pump and cools off, and water pump is directly driven by motor car engine, behind engine misses, water pump just quits work.After the engine start, then water pump is being worked always, and the work of water pump can't be according to actual conditions and start-stop, or because of can not in time moving the order that does not reach cooled engine, but still work when not needing to cool off and waste energy, so it can't adapt to various Environmental Conditions.
Because developing rapidly of automotive engineering, a new generation's its operating mode of engine-cooling system is harsh more, medium temperature during work is at-40 ℃～120 ℃, instantaneous temperature can reach 132 ℃, instantaneous pressure can reach 4Kg, because the poor sealing performance of its live axle of common water pump and pump house leaks very serious; Also, the cooling flow can not be changed, therefore this requirement can't be satisfied according to the actual conditions of motor because the prior mechanical circulating water pump is determined the cooling flow with engine speed.
Summary of the invention
Technical problem to be solved by this invention be overcome the above-mentioned defective of prior art and provide a kind of good seal performance, cooling effect good, can change the automobile cooling water pump that adjust operating mode with motor.
The present invention solves the problems of the technologies described above the technological scheme that is adopted:
Automobile cooling water pump comprises a motor, a Centrifugal water pump pump housing, also comprises a magnetic transmission device, between the rotating shaft of described motor and the blade of Centrifugal water pump by the transmission of magnetic transmission device.
Described magnetic transmission device comprises magnet rotor, a separation sleeve and capsul in the outer magnetic ring rotor,, and micro motor is fixed on the capsul, and the outer magnetic ring rotor is fixed in the rotating shaft of micro motor, with the separation sleeve Spielpassung; The interior magnet rotor of one band rotating shaft is arranged in separation sleeve, and rotating shaft one splaying is assemblied in the rotary axis groove of separation sleeve, and the vanes fixed of described Centrifugal water pump is on interior magnet rotor.
Described motor links to each other with control circuit, and control circuit is controlled by the temperature transducer on the motor.The working signal of motor carries out providing after the data processing to module by the feedback of the temperature transducer on motor motor difference variation again.
For improving magnetic, above-mentioned outer magnetic ring rotor and interior magnet rotor adopt permanent-magnet materials such as neodymium iron boron, ferrite, SmCo, nickel cobalt.
The structure of above-mentioned outer magnetic ring rotor and interior magnet rotor is that magnetic strips embeds in the nonmagnetic substance along circumference, to save magnetic material.
During work, by the temperature operating mode of motor, the signal that provides according to the temperature transducer control circuit and starting electrical machinery, thus driving blade rotation by the magnetic transmission device starts the water cycle cooled engine, makes motor keep the optimum state.
Compared with prior art, the invention has the advantages that:
1, adopt magnetic indirect drive and reliable sealing mechanism is arranged, avoided the leakage that in the past brought by the axle ways of connecting between live axle and blade, guarantee that medium does not leak on the micro motor, so good seal performance.
2, owing to adopt temperature-control circuit to control motor, feed back to module by the temperature transducer on the motor and carry out data processing, can in time start water pump circulation cooling according to the variation of the motor temperature difference, dwindle the motor temperature difference at all, make motor keep the optimum state.
3, can adjust working state according to the operating mode of motor, when motor was not worked, water pump still can be worked, and continued cooled engine; And the cool cycles frequency of water pump is constant substantially, and constant flow is not subjected to the variation of engine speed and changes, and traditional mechanical type water pump along with its circulation frequency of variation of engine speed also along with variation.
4, adopt independent motor driving, drive water pump, therefore avoided the invalid startup of motor, improved the useful horsepower of motor, reduced energy consumption, also reduced the toxic emission of motor, more meet environmental protection requirement without motor.
5, adopt the driven by motor water pump, volume can be dwindled greatly.
