Abstract
The utility model relates to integrated heat abstractor in parallel.One end of its spiral case (2) is totally-enclosed, the other end is air inlet and impeller (3) import, the male half coupling of aforesaid male flange (6) and spiral case (2) other end coordinate with seam locates and is connected with another bolt, 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).There is structure simple, reduce heat abstractor volume, improve air quantity and blast, the feature such as noise decrease and resonance.
Description
Technical field
The utility model patent relates to machine field, is the integration heat abstractor in parallel for motor radiating.
Background technology
Existing heat abstractor, pressure cooling is carried out to motor in the rear and front end, top generally adopting 2 common centrifugal blowers to be arranged on motor respectively, common centrifugal fan noise is large, vibration is large, volume is large, air quantity is little, blast is low, particularly now much high-power, high rotating speed, little inertia, compact variable frequency high-speed motor, although note when designing increasing impedance to suppress high order harmonic component, but because being pass through inverter supply, make the voltage that motor inputs, electric current non-sine, its harmonic component produces extreme influence to the runnability of asynchronous machine, motor is additionally generated heat, temperature rise is too high, efficiency reduces.At this moment, Wind Volume must be installed, heat that motor produces by the heat abstractor of high blast takes away, pressure cooling is carried out to motor.But; because common centrifugal blower volume is too large; the (see figure 1) when the variable frequency high-speed motor that volume is little needs installation 2 centrifugal blowers; cannot realize at all; 1 centrifugal blower that power is little, air quantity is little, blast is low can only be installed and carry out symbolistic cooling; adopt a kind of method that method is cured the symptoms, not the disease again: on motor winding, configure temperature sensor; the hard stop when motor temperature is too high; after motor temperature reduces, continue start run; motor only can be made not burn because of heating, but be certain to reduce electric efficiency, reduce motor useful life.
Existing heat abstractor is generally employing 2 common centrifugal blowers, its defect have following some:
A. during common centrifugal blower mounted in pairs owing to being that 2 common electric machines drive 2 snail box-shrouded impellers respectively, volume is large, cost is high, and the high-speed electric expreess locomotive causing significant volume little cannot realize mounted in pairs at all;
B. 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, particularly powerful centrifugal blower, 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 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, adopts motor for double-ended drive to drive the integration of two blower fans heat abstractor in parallel.
Employing technical scheme of the present utility model, comprise Double shaft-extension motor, spiral case, impeller, 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, 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.
It is simple that the utility model has structure, reduces heat abstractor volume, and improve air quantity and blast, noise decrease and resonance, provide the features such as the heat abstractor met the demands for high-speed electric expreess locomotive.
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-bearing pedestal 6-male flange.
Embodiment
See Fig. 1, comprise Double shaft-extension motor 4, spiral case 2, impeller 3, the both sides end cap central of aforesaid motor 4 has bearing pedestal 5, one end of aforesaid end cap coordinates with the support seam of motor 4 locates, bolt connects, the other end is male flange 6, between male flange 6 and bearing pedestal 5, radial end face has air inlet and reinforcement, one end of its spiral case 2 is totally-enclosed, the other end is air inlet and impeller 3 import, the male half coupling of aforesaid male flange 6 was located with coordinating with seam of spiral case 2 other end, and connect with another bolt, the both sides shaft extension of motor 4 is connected with flat key with the axle sleeve of impeller 3 respectively, carry out fastening with locking nut 1.
Integration combination of radiating device in parallel assembling: first respectively two impellers 3 are inserted in shaft extension position by air inlet direction, and adopt flat key to be connected, locking nut carries out fastening; Again respectively by two spiral cases 2 and end cap male flange 6 carries out seam location, another bolt is connected.Finally by the inverter output terminal sub-connection that the power line of motor is intact with debugging, opening frequency converter can run.When integration heat abstractor in parallel runs, 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.
Claims (1)
1. an integration heat abstractor in parallel, comprise Double shaft-extension motor (4), spiral case (2), impeller (3), the both sides end cap central of aforesaid motor (4) has bearing pedestal (5), one end of aforesaid end cap coordinates with the support seam of motor (4) locates, bolt connects, the other end is male flange (6), between male flange (6) and bearing pedestal (5), radial end face has air inlet and reinforcement, it is characterized in that one end of spiral case (2) is totally-enclosed, the other end is air inlet and impeller (3) import, the male half coupling of aforesaid male flange (6) and spiral case (2) other end coordinate with seam locates, and connect with another bolt, the both sides shaft extension of motor (4) is connected with flat key with the axle sleeve of impeller (3) respectively, carry out fastening with locking nut (1).
