Motor body of the present utility model is located on the mounting platform, and its overcoat electrical machinery cover, mounting platform and electrical machinery cover are provided with thermal-protective coating, isolated to guarantee motor body with the hot gas in the housing of flowing through, make motor not be subjected to the influence of outside high temperature, thereby can under hot environment, work for a long time, therefore, make the low motor of supporting insulation class also can meet the requirement of fire-fighting blower fan, reach the job requirement of high insulation class motor, for example, with insulation class is the B3 type common electric machine of B level, just can reach the same long time of B5 type motor continuous operation under equivalent environment of F level, thereby reduce of the required precision of fire-fighting blower fan, its manufacture cost is reduced with motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial cutaway diagrammatic sketch of the right elevation of Fig. 1.
Embodiment
As shown in Figure 1, fire-fighting blower fan of the present utility model comprises the housing 1 that is provided with intake grill 11 and exhaust outlet 12 and is located at electric axial flow machine 4 in the housing 1.Intake grill 11 and exhaust outlet 12 are located at respectively on the two symmetrical sides of housing.Housing 1 bottom is provided with the mounting platform 3 that is used to install motor 4, and the table top of mounting platform 3 is equipped with the thermal-protective coating that can stop hot gas.Motor 4 comprises motor body 41 and impeller 43, motor body 41 outer sheathed one electrical machinery cover 2 with its sealing, be provided with the thermal-protective coating 9 that the hot gas in the housing 1 that prevents to flow through contacts with motor body between the inner and outer surface of electrical machinery cover 2 or inner and outer surface interlayer, thermal-protective coating 9 mainly is made of heat preservation rock.Electrical machinery cover 2 is provided with the side opening 21 that power supply machine main shaft 42 stretches out, and the size of side opening 21 and electric machine main shaft coupling are to reach better sealing effect, and electric machine main shaft 42 is connected between motor body 41 and the impeller 43.
As Fig. 2, mounting platform 3 is the T type, and it is provided with above housing 1 bottom, with better that motor body 41 is isolated with the hot gas in the housing 1.U type mounting groove 31 is located on the mounting platform 3, is equipped with thermal-protective coating on it.And electrical machinery cover 2 be can with the U type mounting groove 31 fixing inverted U of pegging graft, thereby make things convenient for installing and fixing of motor body and electrical machinery cover 2, mounting groove 31 is in relative seal space with the fixedly connected motor body 41 that makes of electrical machinery cover 2, better and the hot gas isolation.Also be provided with a power line that is used for motor power-supply wire is drawn to the terminal box 8 on the housing 1 on the mounting platform 3 and go out spool 7.
In order to make motor body 41 can be in work under the normal temperature environment, and in time the hot gas that self produced is discharged, mounting platform 3 is provided with air intake pipe 5 and the air outlet tube 6 that is communicated with housing 1 space outerpace, as Fig. 2, tube wall into and out of pipe 5,6 is equipped with thermal-protective coating 9, in case the hot gas of fluid stopping in housing 1 enters, on airduct 5,6, also be provided with a protection wind net 10.
When the utility model is worked under hot environment, motor 4 operations drive aial flow impeller 43 and rotate, high-temperature gas is sucked from intake grill 11, and the housing 1 of flowing through is discharged from exhaust outlet 12 again, be subjected to the influence of hot environment, the temperature in the housing 1 raises rapidly along with the increase of motor working time, and owing to be provided with one deck thermal-protective coating 9 in the inverted U electrical machinery cover 2, the housing 1 interior high-temperature gas of flowing through almost can't infiltrate in the electrical machinery cover 2, thereby little to the influence of motor 4.And because mounting platform 3 is provided with in/out air tube, after the axial-flow leaf that motor 4 carries rotates, housing 1 outer gas at normal temperature is inhaled into by air intake pipe 5, and blow to the radiation tooth on motor 4 surfaces from the heat-dissipating fan of motor 4, discharge from air outlet tube 6 again, heat and a small amount of heat that infiltrates in the electrical machinery cover that motor 4 produces are discharged, thereby make the lower motor of insulation class, as supporting insulation class is the B3 type common electric machine of B level, can move continuously above 30 minutes under 280C ° of hot environment.
