Description
Technical field
This technology relates to a kind of electromagnetic induction energy-saving governor, especially a kind of with water-fog type Wind-cooling type electromagnetic induction energy-saving governor.
Background technology
Electromagnetic induction energy-saving governor, along with state's energy-saving industry is flourish, has started progressively to become one of energy saving speed regulating device generally using in industrial circle.CN102157997A discloses a kind of permanent magnetic speed-adjusting machine with cooling cover, although it is with cooling cover, but in concrete application, for example, in the special producing technological process of metallurgy, chemical industry, if electromagnetic induction energy-saving governor ambient temperature of living in is higher, still there is some problems in its heat radiation with the conductor rotor of cooling cover so.Accumulation as lasting in heat and ambient temperature maintain high temperature, may cause permanent magnet demagnetization.
Summary of the invention
The object of this technology be to provide a kind of simple in structure, reliability is high, easy for installation and there is the air-cooled electromagnetic induction energy-saving governor of water-fog type of better thermal diffusivity, it can effectively reduce the driving temperature of rotor with induction copper ring, expands the use occasion of electromagnetic induction energy-saving governor.
The air-cooled electromagnetic induction energy-saving governor of water-fog type of this technology, comprises mainly by power shaft, the driving rotor portion that drives rotor, induction copper ring, magnetic conduction steel loop forms, mainly by driven that rotor, permanent magnet, output shaft form by driving rotor portion; Permanent magnet is spaced at and is driven rotor periphery, with drive rotor coaxial line driven rotor and output shaft to become power transmission in the circumference to be connected, to be slidably connected at axial one-tenth; Be arranged on the interior Zhou Youyu permanent magnet of the driving rotor on power shaft at radially relative magnetic conduction steel loop, induction copper ring is installed in magnetic conduction steel loop in week; It also comprises for regulating the adjusting device by driving rotor with respect to the axial location of output shaft; Fan housing comprises the ring flat-plate radially extending and the cylinder extending vertically, and outer ring and the cylinder of ring flat-plate join; Driving between rotor one end and ring flat-plate along the flabellum that drives rotor radial to extend; On driving rotor one end relative with ring flat-plate, have air inlet, air inlet is relative with the air gap between induction copper ring and permanent magnet; Cylinder ring around drive rotor periphery and and drive between rotor and have inlet channel; In the periphery that drives rotor, have the cooling bath extending vertically; It also comprises to driving the periphery ejection cooling fluid of rotor or the spray equipment of cooling mist; When flabellum and fan housing rotate with driving rotor, a part of wind enters described air gap through air inlet, blows to the other end that drives rotor; Another part wind blows to along driving rotor periphery the other end that drives rotor through inlet channel.
The beneficial effect of this technology: when this technical work, power shaft connects with prime mover, and output shaft is connected with load, is driven and is driven rotor to do axially reciprocating by adjusting device, thereby make permanent magnet reciprocating motion vertically.So, magnetic flux on induction copper ring change, in induction copper ring, inducing eddy-current power changes, the magnetic field power that vortex flow produces is along with changing, the magnetic field that vortex flow produces and the magnetic field interaction force of permanent magnet be also along with change, and then realize the object of regulation output torque, power output and rotating speed.Water smoke/the water droplet spraying by spray head is taken away fast and is driven the amount of heat accumulating on rotor, simultaneously, the wind that flabellum produces and water smoke/water droplet are jointly to driving rotor, being driven rotor cooling, ensure that permanent magnet, within normal working temperature scope, is improved the stability of electromagnetic induction energy-saving governor and fail safe.
The air-cooled electromagnetic induction energy-saving governor of above-mentioned water-fog type, spray equipment is arranged on ring flat-plate one side; When flabellum and fan housing rotate with driving rotor, under the wind effect that cooling fluid or cooling mist produce at flabellum, a part enters described air gap through air inlet, blows to the other end that drives rotor; Another part blows to along driving rotor periphery the other end that drives rotor through inlet channel.
Spray equipment ejection cooling fluid or cooling mist, meanwhile, along with the wind that the flabellum that drives rotor to rotate produces, part cooling fluid or cooling mist enter air gap with part wind through air inlet, blow to the other end that drives rotor; Also have part cooling fluid or cooling mist to blow to along driving rotor periphery the other end that drives rotor through inlet channel with part wind.Owing to there being cooling bath, can move along cooling bath from inlet channel cooling fluid or cooling mist out, effectively prevent that cooling fluid or cooling mist from departing from the outer peripheral face that drives rotor, strengthened cooling effect.Along mobile cooling fluid or the cooling mist of outer peripheral face of cooling bath and driving rotor, and along the mobile cooling fluid of air gap or cooling mist, take away fast and drive rotor and driven the amount of heat accumulating on rotor, ensure that permanent magnet is within normal working temperature scope, stability and the fail safe of electromagnetic induction energy-saving governor are improved, expand the use occasion of electromagnetic induction energy-saving governor.What adopt this technology is the liquid-cooled electromagnetic induction governor of 250 kilowatts for power, and at water, during as cooling fluid, flow is 48-52L/h(l/h), permanent magnet temperature is the highest at 90 DEG C, has prevented the demagnetization of permanent magnet.
Although as mentioned above, on driving rotor, have cooling bath and can strengthen cooling effect, but applicant's test of many times finds to drive the temperature of rotor still very high, and by changing the quantity of width, the degree of depth and cooling bath of cooling bath, find that cooling-down effect all remains unchanged substantially.In order further to strengthen cooling effect, the air-cooled electromagnetic induction energy-saving governor of above-mentioned water-fog type has cooling annular groove in the other end periphery near driving rotor.Increase after cooling annular groove, it is the liquid-cooled electromagnetic induction governor of 250 kilowatts for power, at water during as cooling fluid, flow is 48-52L/h(l/h), permanent magnet temperature is the highest at 85 DEG C, this may be due to along the mobile cooling fluid of cooling bath or cooling mist after the driving rotor other end arriving away from flabellum, can enter again in cooling annular groove, under the driving rotor rotating drives, again can be in cooling annular groove enters the cooling bath away from the driving rotor other end of flabellum, so cooling effect is better.
The air-cooled electromagnetic induction energy-saving governor of above-mentioned water-fog type, cooling annular groove have two at least, and the degree of depth of cooling annular groove is not less than the degree of depth of cooling bath.Like this, be more conducive to cooling fluid or cooling mist enters cooling annular groove through cooling bath, then enter cooling bath, reduced cooling fluid or the moving resistance of cooling spray.
