Abstract
Vehicle circulating pump includes electromagnetic drive device and leaves, said leaves are installed between the pump shell and the pump cover and are supported on the pump shell by axle, said electromagnetic drive device includes magnet conductor which is supported on the pump shell by axle, the magnet conductor is bound by coil around itself, the soil is connected with the control circuit, the main bulk of said leaves is circular column and is nested out the pump shell, the leaves main bulk and the magnet conductor in the pump shell are composed into inner and outer shrink-fit structure. The present invention has the advantages: good sealing performance, small noise and strong anti-electronic jamming, it avoids the ineffective start of motor, raises the effective power of the engine, reduces energy consumption, and also reduces engine waste gas emissions, it meets the environmental requirements and has long product life to make engine remain the best condition.
Description
Technical field
The present invention relates to a kind of pump, particularly a kind of automobile circulating water pump that is used for the automobile cooling.
Background technique
Car engine cooling system is to guarantee motor car engine not overtemperature, the requisite system of automobile normal running, existing car engine cooling system generally drives medium circulation by conventional pump, pump is driven by motor car engine, behind the engine misses, pump just quits work, and therefore can't adapt to various Environmental Conditions.
Water pump in the car engine cooling system is because of its service condition and little, the no electromagnetic interference of environmental requirement noise, and what pump was carried is the liquid of high temperature, high pressure or the medium of semi liquid state.Because the pump housing and motor are an integral body, therefore to guarantee that medium must not leak in motor and the circuit control panel, particularly under the liquid condition of High Temperature High Pressure, to accomplish ten fens difficulties of this point, existing water pump can't satisfy this requirement.Because water pump need could drive by motor, and commutator and brush are arranged in the general electric machine structure, causes quick abrasion because of rubbing contact in the using process, the life-span is short.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above-mentioned defective of prior art and a kind of automotive electronics circulating water pump is provided, and makes its life-span long, anti-interference good.
The present invention solves the problems of the technologies described above the technological scheme that is adopted:
Circulation pump for auto, comprise electromagnetic drive mechanism and blade, described blade places the space between pump case and pump cover, and is supported on the pump case by axle, and described electromagnetic drive mechanism comprises magnet case, magnet case is supported on the pump case by axle, the outer coiling of magnet case, coil links to each other with control circuit, and described blade body is cylindrical body, be enclosed within outside the pump case, and constitute inside and outside shrink-fit structure with placing its inboard magnet case.
The axle of above-mentioned support magnet and the axle of support blade are same axle.
The circuit control panel of above-mentioned control circuit is installed on the axle.
Above-mentioned magnet case can be silicon steel sheet etc.
Above-mentioned blade is equivalent to the rotor of motor, and silicon steel sheet is equivalent to the stator of motor, and the rear blade of therefore switching on just can rotate, thereby drives medium circulation.
Above-mentioned control circuit links to each other with the sensor of motor, and is controlled the break-make of control circuit by the temperature transducer on the motor.Feeding back to module by the temperature transducer on the motor carries out data processing and keeps the engine operating condition temperature difference.After temperature surpassed certain limit, working signal just was sent to the automotive electronics circulating water pump and starts water pump, carried out the engine cycles cooling, and the temperature of motor is controlled in the scope of setting.
Compared with prior art, the invention has the advantages that:
1, blade and electromagnetic drive mechanism are arranged in two cavitys of isolating fully, the electromagnetic system of its rotation of the corresponding driving with it of blade is isolated fully, so medium can not enter in the electromagnetic drive mechanism good seal performance.
2, the electromagnetic drive mechanism of entire mechanism seals fully, so noise is little, and anti-electronic interferences is strong.
3, the medium circulation of pump is controlled separately by circuit, do not work with the rotation of motor, also not because of motor stop to quit work, therefore independence is good, and the good cooling results of automobile has also been avoided the invalid startup of motor, improved the useful horsepower of motor, reduced energy consumption, also the toxic emission of minimizing and motor meets environmental protection requirement.
4, electromagnetic drive mechanism is simple in structure, interelement connection with contact lessly, do not have the commutator and the brush of conventional motors, therefore do not have the wearing and tearing between parts, life of product is long.
5, 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 be according to the variation of the motor temperature difference, the cooling of primer pump circulation in time, dwindle the motor temperature difference at all, make motor keep the optimum state.
6, adopt electromagnetic drive mechanism, volume can be dwindled greatly.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, circulation pump for auto comprises electromagnetic drive mechanism and vane rotor 12, vane rotor 12 places the space of being made up of pump case and pump cover, pump case 3 and pump cover 1 are fixing by screw 11, bring the mouth of a river 101 and water outlet 102 on the pump cover 1 into, vane rotor 12 is supported on the pump case 3 by axle 9 by bearing 10, and axle 9 outer ends are by pad 2, jump ring spacing 13.
Described electromagnetic drive mechanism comprises and coils 4 silicon steel sheet 8, and is supported on pump case 3 centers by axle 9.
Described vane rotor 12 is made by magnetic material, and its main body is cylindrical body, is enclosed within outside the pump case 3, and corresponding silicon steel sheet 8 places pump case 3 inboards, and constitutes inside and outside chimeric mechanism with vane rotor.
The structure of above-mentioned vane rotor 12 is that magnetic strips embeds in the nonmagnetic substance along circumference, to save magnetic material.
Above-mentioned axle 9 the other ends are fixed on the circuit control panel 7, and electronic control plate 7 is fixed on the pump case 3.
Above-mentioned silicon steel sheet 8 and vane rotor 12 are equivalent to the stator and the rotor of motor, therefore when the coil electricity in the silicon steel sheet, just can produce magnetic field, with the magnet effect on the impeller, drive the vane rotor rotation of overcoat, thereby will discharge from water outlet in the medium in the housing, water just forms circulation from the water intake of housing to water outlet.
When not needing to cool off, control circuit is with regard to no electric circuit, and circulation pump for auto is not just worked, so can not influence each other between motor and circulation pump for auto, and cooling system is independent and not with engine operation.
