Problems solved by technology
CN102157997A discloses a permanent magnet speed governor with a cooling air cover. Although it has a cooling air cover, in specific applications, such as in special production processes of metallurgy and chemical industry, if the electromagnetic induction energy-saving speed governor The ambient temperature is relatively high, so there are still some problems in the heat dissipation of the conductor rotor with the cooling wind cover
If the heat continues to accumulate and the ambient temperature remains high, it may cause permanent magnet demagnetization

The invention provides a spray-type air-cooled electromagnetic induction energy-saving speed governor which is simple in structure, convenient to install and better in heat dissipation performance. The temperature of a driving rotor can be lowered, and the using occasions of the electromagnetic induction energy-saving speed governor are expanded. The spray-type air-cooled electromagnetic induction energy-saving speed governor comprises a driving rotor part and a driven rotor part. A driven rotor is connected with an output shaft in a sliding mode in the axial direction. A magnetic conduction steel ring is arranged on the inner circumference of the driving motor, and an induction copper ring is arranged on the inner circumference of the magnetic conduction steel ring. A fan housing comprises an annular plate and a cylinder, and fan blades are located between one end of the driving rotor and the annular plate. An air inlet opposite to an air gap is formed in one end of the driving rotor. An air inlet channel is arranged between the cylinder and the driving rotor. A cooling groove is formed in the periphery of the driving rotor. The speed governor further comprises spraying devices for spraying cooling liquid or cooling spray to the periphery of the driving rotor. When the fan blades and the fan housing rotate along with the driving rotor, one part of air enters the air gap through the air inlet to be blown to the other end of the driving rotor, and the other part of the air is blown to the other end of the driving rotor along the periphery of the driving rotor through the air inlet channel.
Description
technical field [0001] The technology relates to an electromagnetic induction energy-saving speed regulator, in particular to a water mist air-cooled electromagnetic induction energy-saving speed regulator. Background technique [0002] With the vigorous development of the domestic energy-saving industry, the electromagnetic induction energy-saving speed controller has gradually become one of the energy-saving speed controllers commonly used in the industrial field. CN102157997A discloses a permanent magnet speed governor with a cooling air cover. Although it has a cooling air cover, in specific applications, such as in special production processes of metallurgy and chemical industry, if the electromagnetic induction energy-saving speed governor The ambient temperature is relatively high, so there are still certain problems in the heat dissipation of the conductor rotor with the cooling wind cover. If the heat continues to accumulate and the ambient temperature remains high...
