Abstract
The utility model relates to a high-heat radiation electric blower. The main air intake of the present various electric blowers does not pass through the outer circle of an electric motor. A high-heat radiation electric blower of which the complete air intake passes through the outer circle of the electric motor is designed in order to decrease the temperature rise of the electric blower, clean the working environment of the electric motor and improve the efficiency and the service life. The high-heat radiation electric blower is particularly suitable for the operation of long time and can be used in the environment with dust or corrosive gas.
Description
A kind of high efficiency and heat radiation electric blower that is different from existing product air intake mode, the existing electric blower that generally uses, its main air output be without the motor cylindrical, but 2. air intake of the crust of weathering in the past.The back crust of weathering that also allows that has is opened a garden shape mouth also bigger than motor diameter in the middle of 3., allows the gap of distinguished and admirable mistake between them, makes the heat radiation of motor one end; Also have plenty of the front and rear cover of allowing and constitute many vents, make and a spot ofly distinguished and admirablely go into motor internal and dispel the heat, motor itself has sink besides.Some heat radiation of existing electric blower is undesirable, and some temperature rise is also easily stopped up rotor by dust, increases bearing wear, has influenced product performance to some extent.
Task of the present utility model is by improving the air intake mode of electric blower, reducing the temperature rise of motor.The working environment of cleaning motor, thereby the efficient and the working life of improving electric blower.
The utility model Fig. 1 is a plan view, Fig. 2 is a plan view, 7. fan housing locates to be broken section, 2. the preceding crust of weathering seals, front cover 5. with rear end cover 9. due to the trim ring at iron core two ends 6. being benchmark and seam is joined name, and 8. be fixed as integral body with three long screws, 3. described overall fixed goes up at the back crust of weathering, 3. the back crust of weathering has intake grill, and 3. the complete machine air quantity is entered by the back crust of weathering.But it is very important to open a great intake grill at the back crust of weathering on 3., and this opening section is long-pending, and deduct the motor front cover 5. be 2.2 to 2.8 with the ratio of exhaust outlet minimum sectional area behind the maximum secting area.Make a fan housing and 7. cover motor, form air inlet duct, fan housing is front opening 7., and the rear end be many ventilation cellular types, 1. is fixed on front cover by three screws and 5. goes up, and makes an air door more 10., the adjusting air output, minimum air output by air door 10. center hole enter.Back crust of weathering intake grill 3. also can with front cover 5. maximum secting area equate, but this moment, 5. 3. the back crust of weathering should have certain distance with front cover.
Advantage of the present utility model has been that 7. fan housing has formed ventilation flue, and 9. 5. the front cover on the motor play fixed stator with rear end cover, and more important is protection, and motor does not blow into dust.Reduced technology difficulty and processing cost after saving stator casing, the stator cylindrical is directly exposed in the ventilation flue, more helps heat radiation.The utility model electric machine temperature rise is than the low 45-65% of existing product, and the active power of motor improves greatly, needn't often overhaul, and also prolong greatly working life.
3. 3. intake grill sectional area when 5. maximum secting area equates with front cover of the crust of weathering behind the utility model, the back crust of weathering multiply by 2.2 to 2.8 times that should be the exhaust outlet minimum sectional area behind the front cover girth 5. with front cover distance 5..Air intake door 10. with fan housing 7. not the ratio of total air intake sectional area at the place of overlapping each other and exhaust outlet minimum sectional area also should be 2.2 to 2.8.This specification all is suitable for the high, medium and low voltage electric blower.The utility model optimum long-play and be used in dust or the environment of the gas that is corrosive in.
Claims (6)
