Abstract
The utility model relates to a direct coupled two-stage axial-flow fan with one motor, which comprises an outer cylinder, wherein a casing is composed of the outer cylinder and a wind collecting device and a diffusion cylinder which are arranged at both sides of pf the outer cylinder; a rectifying cover, a first-stage moving blade, a motor, a second-stage moving blade and a rectifying body are orderly arranged in the casing; an inner cylinder is arranged out of the motor; the first-stage moving blade and the second-stage moving blade are directly connected with shafts protruded from both sides of the motor; guide blades are arranged between the inner cylinder and the outer cylinder. The motor rotates to drive the first-stage moving blade and the second-stage moving blade to rotate in the same direction; airflow passes flows through the first-stage moving blade, the guide blades and the second-stage moving blade at uniform flow velocity after the finishing of the rectifying cover and the wind collecting device, is decelerated and pressurized by the diffusion cylinder, and flows out of the axial-flow fan with designed pressure and flow quantity. The utility model omits a shaft coupling and a bearing seat, which can reduce the processing quantity, can shorten the construction period and can reduce the cost.
Description
Technical field
The utility model relates to a kind of axial-flow blower, the two-stage axial-flow blower that particularly a kind of separate unit motor is direct-connected.
Background technique
Axial-flow blower is the universal machine that is widely used in the industrial or agricultural every field, is made of rotor and stator two large divisions.The rotor of axial-flow blower is by motor driving, general multistage axial flow blower fan, as the early stage blower fan series of promoting such as 2K56 of China's blower fan industry, all need to be connected with fan rotor by shaft joint, so just need a major axis and corresponding bearing support, this just causes the machining amount of sizable axle and bearing support, and the manufacture cycle is long, and the user prepares the also corresponding increase with cost of capital construction cycle on motor basis and bearing basis for blower fan simultaneously.
Summary of the invention
Use the amount of machining that shaft joint and bearing support bring and the increase of cost in order to solve, the two-stage axial-flow blower that provides a kind of separate unit motor direct-connected is provided the purpose of this utility model, this blower fan has saved shaft joint and bearing support, has shortened the duration, has reduced cost.
The technological scheme that the utility model adopted is: the direct-connected two-stage axial-flow blower of separate unit motor, comprise urceolus, the wind collecting unit on urceolus and its both sides and diffusion barrel are formed housing, in the housing, cowling, first order movable vane, motor, second level movable vane, rectification body are provided with in proper order, motor is provided with inner core outward, and first order movable vane directly is connected with the axle that stretch out at the motor two ends with second level movable vane.
The utility model is also on the inner core, install stator between inner core and the urceolus.
The utility model can also be in the perforate along the circumferential direction of the surface at inner core two ends, the passage open interior of stator.
The shape of stator can make the wing blade or the common veneer blade profile of wing blade or inner hollow.
The beneficial effects of the utility model are: adopt the two ends that the two-stage axial flow fans rotor are directly installed on rotor axis of electric on the structure, shaft joint and bearing support have been saved, simultaneously, the stator between the two-stage movable vane is as support, and motor is installed in the stator of stator support.The machined piece of blower fan has only few parts such as wheel hub of fan rotor, has significantly reduced amount of finish, has shortened the duration, cost is reduced.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1. cowling, 2. wind collecting unit, 3. first order movable vane, 4. stator, 5. motor, 6. inner core, 7. second level movable vane, 8. urceolus, 9. rectification body, 10. diffusion barrel, 11., 12..
Embodiment
Below in conjunction with accompanying drawing structure of the present utility model and working principle are elaborated.
The direct-connected two-stage axial-flow blower of separate unit motor, comprise urceolus 8, urceolus 8 is formed housing with the wind collecting unit 2 and the diffusion barrel 10 on its both sides, in the housing, cowling 1, first order movable vane 3, motor 5, second level movable vane 7, rectification body 9 orders are provided with, the motor 5 outer inner cores 6 that are provided with, first order movable vane 3 directly is connected with axle 12 with the axle 11 that stretch out at motor 5 two ends with second level movable vane 7, stator 4 is installed on the inner core 6, between inner core 6 and the urceolus 8, stator 4 plays the supporting effect of inner core 6, stator 4 be shaped as common veneer blade profile.
The shape of stator 4 can also be made the wing blade of wing blade or inner hollow, as the heat dissipation channel of motor, can also adopt in addition in the perforate along the circumferential direction of the surface at inner core 6 two ends, at the passage open interior of stator 4, as the heat dissipation channel of motor.
When axial-flow blower is worked, the rotation of motor 5 drives first order movable vane 3 and second level movable vane 7 rotates in the same way, air-flow is through the arrangement of cowling 1 and wind collecting unit 2, flow to first order movable vane 3 with even velocity, air-flow through first order movable vane 3 add merit after, the pressure of air-flow, speed and direction all have bigger variation, pass through the adjustment of stator 4 again, flow into second level movable vane 7 in mode preferably, after second level movable vane 7, the air-flow outside merit that adds of not reentrying, but through diffusion barrel 10 deceleration superchargings flows out blower fan by the pressure and the flow of design.
