The centrifugal blower current collector adjusting device is simple in structure and convenient to operate, the nut is loosened, the adjusting ring is adjusted through the handle, after the adjusting ring is loosened, the current collector is moved up and down and left and right by hands, an opening clearance between the current collector and the impeller meets the standard requirement, the nut is screwed after the opening clearance is adjusted, so that performance of a blower is guaranteed, and the service life of the blower is improved.
Description
Technical field
The utility model relates to the ventilator technical field, specifically is a kind of centrifugal blower slip ring controlling device.
Background technique
The import slip ring is the important accessory of blower fan, forms tapered runner with streamlined windscreen, and air-flow is accelerated at this, sets up uniform velocity field and pressure field before the import of blower fan, improves fan efficiency to reduce flow losses.Because gas flow rate is little in the slip ring, pipe range is shorter, and flow losses own are little, can satisfy uniform flow field and the guaranteed efficiency of condition for import generally speaking.
The import slip ring is located at the front end of impeller intake grill, and blower fan need to be regulated impeller and met design requirement with the size that the import slip ring contains mouthful gap in assembly process, and performance reaches design load during the assurance fan operation.Can't adjust but existing centrifugal blower, slip ring and impeller contain mouthful gap in the process of assembling, can not meet design requirement; The performance of blower fan can't guarantee in the process of using, and collision easily between slip ring and the impeller simultaneously is easy to wear, the working life of having reduced blower fan.
The model utility content
The utility model proposes a kind of centrifugal blower slip ring controlling device, easy to operate, simple in structure, regulate mouthful gap that contains between impeller and the import slip ring quickly and easily.
The technical solution of the utility model is achieved in that a kind of centrifugal blower slip ring controlling device, comprise the controlling device of being located on the slip ring, described controlling device comprises the Adjusting ring of being with handle, and described Adjusting ring is fixed on the slip ring with connecting bolt, nut by briquetting.
As preferably, described briquetting is positioned on the Adjusting ring, and described connecting bolt runs through briquetting, Adjusting ring and slip ring to be fixed by nut.
As preferably, be provided with plain washer between described connecting bolt and the slip ring inwall.
As preferably, be provided with lock washer between described briquetting and the nut.
As preferably, weld between described handle and the Adjusting ring.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, easy to operate, unclamp nut and regulate Adjusting ring by handle, Adjusting ring transfer the pine back manually about, move forward and backward slip ring, guarantee that mouthful gap that contains between slip ring and the impeller reaches standard-required, after containing a mouthful gap and mixing up, fastening nut again, thereby guaranteed the performance of blower fan, improved the working life of blower fan.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model controlling device.
Among the figure: 1, slip ring; 2, handle; 3, Adjusting ring; 4, bolt; 5, nut; 6, lock washer; 7, briquetting; 8, plain washer; 9, impeller.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, a kind of centrifugal blower slip ring controlling device comprises the controlling device of being located on the slip ring 1, and described controlling device comprises the Adjusting ring 3 of being with handle 2, and described Adjusting ring 3 is fixed on the slip ring 1 by briquetting 7 usefulness connecting bolts 4, nut 5.This controlling device is simple in structure, easy to operate, unclamp nut 5 and regulate Adjusting rings 3 by handle 2, Adjusting ring 3 transfer the pine back manually about, move forward and backward slip ring 1, assurance contains a mouthful gap and reaches standard-required, after containing a mouthful gap and mixing up, fastening nut 5 again, thereby guaranteed the performance of blower fan.
Wherein, described briquetting 7 is positioned on the Adjusting ring 3, and it is fixing by nut 5 that described connecting bolt 4 runs through briquetting 7, Adjusting ring 3 and slip ring 1.Adjusting ring 3, briquetting 7 are fixed by bolt 4, nut 5, are convenient to dismounting, install, and are convenient to regulate.
Further, be provided with plain washer 8 between described connecting bolt 4 and slip ring 1 inwall.Plain washer 8 reduces the friction of bolts 4 and slip ring 1 inwall, can also prevent flow leakage, has to isolate and prevent from getting loose or the effect of dispersive pressure.
Further, be provided with lock washer 6 between described briquetting 7 and the nut 5.Lock washer 6 prevents that nut 5 is loosening after tightening.
Further, welding between described handle 2 and the Adjusting ring 3.Handle 2 is connected with Adjusting ring 3, is convenient to regulate.
The utility model Adjusting ring 3 is fixed on the air intake tube by briquetting 7 usefulness attachment bolts 4, nut 5, plain washer 8, lock washer 6, handle 2 is welded on the Adjusting ring 3, in the blower fan assembly process, when needs regulate between slip ring 1 and the impeller 9 contain mouthful gap the time, unscrew nut 5, move Adjusting ring 3 by handle 2, then about, move forward and backward slip ring 1, guarantee that containing a mouthful gap reaches standard-required.After containing a mouthful gap and mixing up, at last nut 5 is tightened.Whole process operation gets up easily, and impeller 9 contains mouthful gap with slip ring 1 and also guarantees easily, thereby has guaranteed the performance of blower fan.
The above only is 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 modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
