Description
Technical field
The utility model patent relates to machine field, is the integration for motor radiating and receipts or other documents in duplicate air outlet heat abstractor.
Background technology
Existing heat abstractor, pressure cooling is carried out to motor in the top, any one end, two ends generally adopting common centrifugal blower to be arranged on motor, and common centrifugal fan noise is large, vibration is large, volume is large, air quantity is little, blast is low, can not adapt to the development of modern industry completely.
Existing heat abstractor be generally adopt common centrifugal blower, its structure and shape great majority for shown in Fig. 1, its defect have following some:
A. the drive motors of common centrifugal blower is installed in spiral case single shaft in 90 °, single flange cantilever type, what matched is again common serial motors, noise is large, vibration is large, noise level limit and the vibration limit value of variable frequency high-speed motor can not be met completely, motor bearings can be caused to burn because of the resonance of centrifugal blower transmission;
What c. the drive motors of common centrifugal blower was matched is common serial motors, and its rotating speed is generally about 2900r/min, and air quantity is little, blast is low, the high heat that variable frequency high-speed motor produces cannot be taken away, and effectively forces cooling to variable frequency high-speed motor.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, improves air quantity and blast, the integration also receipts or other documents in duplicate air outlet heat abstractor of noise decrease and vibration.
Employing technical scheme of the present utility model, comprise Double shaft-extension motor, spiral case, impeller, wind-guiding base, the end cap central on aforesaid motor both sides has bearing pedestal, one end of aforesaid end cap coordinates with the support seam of motor locates, bolt connects, the other end is male flange, between male flange and bearing pedestal, radial end face has air inlet and reinforcement, aforesaid wind-guiding base has in Y-shaped air duct, upper end is two air intakes, lower end is single air-out, one end of its spiral case is totally-enclosed, the other end is air inlet and impeller inlet, the male half coupling of aforesaid male flange and the spiral case other end coordinate with seam locates, and connect with another bolt, the both sides shaft extension of motor is connected with flat key with the axle sleeve of impeller respectively, carry out fastening with locking nut.Two air inlet of wind-guiding base upper end is equal with two spiral case lower end air outlet sizes, and is connected with other bolt with flange respectively.
It is simple that the utility model has structure, energy-conservation, noise reduction, air quantity and the feature such as blast is large.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the utility model sectional structure schematic diagram.
In figure: 1-locking nut 2-spiral case 3-impeller 4-motor 5-wind-guiding base
6-Y font air duct 7-bearing pedestal 8-male flange.
Embodiment
See Fig. 1, comprise Double shaft-extension motor 4, spiral case 2, impeller 3, wind-guiding base 5, the end cap central on aforesaid motor 4 both sides has bearing pedestal 7, one end of aforesaid end cap and the support of motor 4 coordinate with seam locate, bolt is connected, the other end is male flange 8, between male flange 8 and bearing pedestal 7, radial end face has air inlet and reinforcement
Aforesaid wind-guiding base 5 has in Y-shaped air duct 6, its upper end is two air intakes, lower end is single air-out, one end of aforementioned spiral case 2 is totally-enclosed, the other end is air inlet and impeller 3 import, the male half coupling of aforesaid male flange 8 is located with coordinating with seam of spiral case 2 other end and is connected with another bolt, and the both sides shaft extension of motor 4 is connected with flat key with the axle sleeve of impeller 3 respectively, carries out fastening with locking nut 1.Two air inlet of wind-guiding base 5 upper end is equal with two spiral case 2 lower end air outlet sizes, and is connected with other bolt with flange respectively.
The inverter output terminal sub-connection intact with debugging by the power line of motor, opening frequency converter can run.During integrated also receipts or other documents in duplicate air outlet heat abstractor operation, required a large amount of air intake of device all sucks from the enterprising air port of end cap, because wheel speed is high, the Wind Volume produced, high blast directly carry out pressure cooling to high-speed electric expreess locomotive, and effetive zone is walked high-speed electric expreess locomotive and additionally to be generated heat produced heat.
Integration also receipts or other documents in duplicate air outlet heat abstractor adopts the global design in parallel of 1 motor driven, 2 impellers, two axial force of impeller are balanced to holding, axial force more than 97% can be reduced, this device is motor Double shaft-extension, double flange flange coordinates wind-guiding base to form stable support with 2 spiral cases to install respectively, can noise decrease and vibration about 30%.
Integration receipts or other documents in duplicate air outlet heat abstractor drive motors need not fan cooling, while a large amount of wind regimes required when plant running all enter from motor rear and front end lid air inlet, effective cooling is carried out to the surface temperature of the drive motors of this device, electrical machinery life more than 15% can be extended.
