Abstract
The utility model discloses a kind of small flow multistage centrifugal blower, comprise base, and the motor, coupling and the centrifugal blower that are arranged on base, dynamic output shaft on described motor, dynamic input shaft on described centrifugal blower, described pto＝power take-off connects described power input shaft by coupling.The utility model by by direct-connected for centrifugal blower motor, instead of the belt transmission of roots blower, centrifugally instead of positive displacement, and all comparatively roots blower is simple for the operation of Multi-stage centrifugal fan, installation, maintenance and maintenance, and working life is also long than roots blower.
Description
Technical field
The utility model relates to a kind of small flow multistage centrifugal blower.
Background technique
The long-time use of roots blower both domestic and external in China through all trades and professions, find a lot of problem, main frame working life short (continuous service time is 3-5), equipment noise and vibration equipment larger, main frame impeller requires high to coaxial bearing degree, impeller engagement easily damages, belt is long for running time, easily loosen, also easily damage, standby redundancy is changed many, particularly filter core and lubricant oil, fuel tank internal is splash lubrication, and bearing and synchromesh gear heat radiation have problem, and inner impeller heat radiation is slower.
Model utility content
The utility model proposes a kind of small flow multistage centrifugal blower, by by direct-connected for multistage centrifugal blower motor, instead of the belt transmission of roots blower, centrifugally instead of positive displacement, the operation of Multi-stage centrifugal fan, install, maintenance and maintenance all comparatively roots blower are simple, and working life is also long than roots blower.
Of the present utility modelly to realize particular by following technological scheme:
A kind of small flow multistage centrifugal blower, comprise base, and be arranged on motor, coupling and the centrifugal blower on base, dynamic output shaft on described motor, dynamic input shaft on described centrifugal blower, described pto＝power take-off connects described power input shaft by coupling.
Further, described base is provided with coupling shield, and it is inner that described coupling is in described coupling shield.
The beneficial effect that the utility model produces is: the parameter of the utility model centrifugal blower can substitute roots blower completely, has lacked belt transmission, and efficiency comparatively roots blower is high by about 8%, control simple and convenient, fault is less, and noise is also little, maintenance and easy to maintenance, working life, comparatively roots blower was long.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of small flow multistage centrifugal blower, comprise base 1, and the motor 2, coupling 4 and the centrifugal blower 3 that are arranged on base 1, dynamic output shaft 5 on described motor 2, dynamic input shaft 6 on described centrifugal blower 3, described pto＝power take-off 5 connects described power input shaft 6 by coupling 4, base 1 is provided with coupling shield 7, and it is inner that described coupling 4 is in described coupling shield 7.
Working principle of the present utility model is: motor 2 is opened, and the pto＝power take-off 5 on motor 2 rotates, and drives power input shaft 6 to rotate by coupling 4, and power input shaft 6 rotates startup centrifugal blower 3 and carries out work.By the direct-connected motor of coupling 4 and centrifugal blower in the utility model, instead of the belt transmission of roots blower, centrifugally instead of positive displacement, the operation of Multi-stage centrifugal fan, install, maintenance and maintenance all comparatively roots blower are simple, and working life is also long than roots blower.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
