Description
Technical field
The present invention relates to a kind of motor, relate in particular to a kind of fire-proof motor.
Background technology
Fire-proof motor is a kind of a kind of motor that can use in inflammable and explosive factory, does not produce electric spark during operation.Fire-proof motor is mainly used in colliery, petroleum gas, petrochemical industry and chemical industry.In addition, also be widely used in departments such as weaving, metallurgy, town gas, traffic, grain and oil processing, papermaking, medicine.Fire-proof motor, as main power-equipment, is generally used for driving pump, blower fan, compressor and other gearings.Because the environment for use of fire-proof motor is special, to the heat dissipation problem of motor become particularly important, fire-proof motor is for explosion-proof purpose, and electric inner machine seals, and the heat exchange amount of the casing of enclosed motor and inner air is little, radiating effect is poor, only by being opened in casing, be provided with the spiral channel heat radiation, but spiral channel is positioned at the stator outside, the heat radiation of rotor is especially poor, thereby the excess Temperature that causes bearing, be unfavorable for the safe operation of motor.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of perfect heat-dissipating, especially the good fire-proof motor of the thermal diffusivity of rotor.
Technical solution of the present invention is achieved in that a kind of fire-proof motor, comprise casing, armature spindle, stator and rotor, described armature spindle and stator are arranged in casing, described armature spindle passes stator, be provided with rotor between described armature spindle and stator, be provided with spiral channel in described casing, described spiral channel is positioned at the stator outside, and the front end of described armature spindle is provided with fan; Described armature spindle is provided with wind blocking cylinder; Described wind blocking cylinder is between fan and rotor; The diameter of described wind blocking cylinder is less than the diameter of fan; Have runner in described wind blocking cylinder; The import of described runner is parallel with armature spindle, and towards rotor; The outlet of described runner is perpendicular to armature spindle; Axially have respectively the first ventilation hole and the second ventilation hole on described stator and rotor; Described the first ventilation hole is near spiral channel.
Preferably, the import of described the second ventilation hole and runner is positioned on the same level line.
Preferably, described casing is provided with water inlet and the delivery port that communicates with spiral channel.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Fire-proof motor of the present invention, rotor transfers heat to the air in the second ventilation hole, stator transfers heat to the air in the first ventilation hole, near spiral channel, thermal resistance is little, has increased the heat exchange amount of air and water due to the first ventilation hole, and the rising of the air themperature in the second ventilation hole is rear under the effect of fan, after flowing to runner, through runner, enter in the first ventilation hole, make air themperature reduce the rear circulation that continues.Fire-proof motor of the present invention, radiating effect is obvious, and especially the good heat dissipation effect of rotor, avoid the Bearing Temperature that causes because temperature of rotor is too high, guaranteed the safety and reliability of motor operation.
