Abstract
The utility model relates to a centrifugal fan, in particular to a supporting tube group for a gas inlet box of a centrifugal fan shell. According to the supporting tube group, the rigidity of the gas inlet box of the centrifugal fan shell can be increased, and the deformation of the gas inlet box of the centrifugal fan shell is avoided. The centrifugal fan shell comprises the gas inlet box which is provided with the supporting tube group which can increase the rigidity of the centrifugal shell and avoid the deformation of the centrifugal shell. The supporting tube group comprises a protective ring and a supporting tube. The supporting tube group for the gas inlet box of the centrifugal fan shell effectively improves the rigidity of the gas inlet box of the centrifugal fan shell and avoids the deformation of a gas inlet box of a centrifugal fan shell group.
Description
Technical field
The utility model relates to a kind of centrifugal blower, specifically a kind of centrifugal fan casing group inlet box support tube group.
Background technique
Centrifugal blower is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Centrifugal blower is widely used in ventilation, dust discharge and the cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building.
Centrifugal blower is larger, rigidity is more bad, easier distortion, the inlet box of casing group particularly, the plate of inlet box is the thinnest part in the whole casing generally speaking, namely be out of shape the most serious part, think the normal use of casing, must manage to increase casing rigidity, prevent the casing distortion, the reason of centrifugal fan casing group inlet box distortion is a lot, cause the centrifugal fan casing vibration such as the reason owing to air-flow, ground is unequal, but that all is external factor, for centrifugal fan casing group inlet box itself, its Deformation Reasons mainly contains two, the one, the air inlet boxboard is too thin, increases sheet metal thickness and prevents that the casing distortion from not only having increased cost of material, simultaneously manufacture cost, the civil engineering cost at cost of transportation and user scene etc. all can increase, so for large centrifugal fan, the increase sheet metal thickness prevents that the method for casing distortion from being worthless, the 2nd, and the span of inlet box is oversize, and this inlet box will be easy to distortion.
The model utility content
The technical problems to be solved in the utility model provides a kind of centrifugal fan casing group inlet box support tube group, increase centrifugal fan casing group inlet box rigidity, prevent the distortion of centrifugal fan casing group inlet box.
For solving the problems of the technologies described above, the centrifugal fan casing group inlet box support tube group of the technical solution of the utility model, it comprises inlet box, is provided with the support tube group that can increase casing rigidity, prevent the casing distortion at inlet box.
Wherein, owing at inlet box the support tube group has been installed, so inlet box can not be out of shape in the thin situation of the plate of the inlet box that guarantees the casing group, and increased the rigidity of inlet box, even owing to the reason of air-flow causes centrifugal fan casing vibration, ground injustice, the distortion of inlet box can not occur also.Described support tube group comprises guard ring and support tube; this guard ring is located at the support tube two ends, and this guard ring has not only guaranteed the wearing and tearing of the support tube that contacts with inlet box, and so that support tube stably contact with inlet box; and support tube employing steel pipe, so that support effect is better.Described support tube group can be one or several support tube groups, according to the concrete condition of inlet box distortion or the specific works environment of centrifugal blower, increases the number of support tube group, and centrifugal blower inlet box rigidity is increased, and is not easy distortion.
The centrifugal fan casing group inlet box support tube group of the technical solution of the utility model, when centrifugal blower moves, because the support tube group is installed in the inlet box, even the centrifugal blower vibration is violent, centrifugal blower is in the ground injustice, perhaps the span of inlet box is oversize, and inlet box is deformed, and makes inlet box increase rigidity.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes 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 according to these accompanying drawings other accompanying drawing.
Fig. 1 is centrifugal fan casing group inlet box of the present utility model with the structural representation of support tube group.
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.
The utility model provides a kind of centrifugal fan casing group inlet box support tube group, as shown in Figure 1, comprises inlet box 1, is provided with the support tube group 2 that can increase casing rigidity, prevent the casing distortion at inlet box 1.Owing at inlet box 1 support tube group 2 has been installed, so inlet box 1 can not be out of shape in the thin situation of the plate of the inlet box 1 that guarantees the casing group, and increased the rigidity of inlet box 1, even owing to the reason of air-flow causes centrifugal fan casing vibration, ground injustice, the distortion of inlet box 1 can not occur also.
In the utility model; described support tube group 2 comprises guard ring 202 and support tube 201; guard ring 202 is located at support tube 201 two ends; guard ring 202 has not only guaranteed the wearing and tearing of the support tube 201 that contacts with inlet box 1; and so that support tube 201 stably contact with inlet box 1; and support tube 201 can adopt steel pipe, so that support effect is better.
As a kind of specific embodiment of the present utility model, described support tube group 2 can be one or several support tube groups, according to the concrete condition of inlet box 1 distortion or the specific works environment of centrifugal blower, increase the number of support tube group, centrifugal blower inlet box 1 rigidity is increased, can not be out of shape.
The centrifugal fan casing group inlet box support tube group of the technical solution of the utility model, when centrifugal blower moves, because support tube group 2 is installed in the inlet box 1, even the centrifugal blower vibration is violent, centrifugal blower is in the ground injustice, perhaps the span of inlet box 1 is oversize, and inlet box 1 is deformed, and makes inlet box 1 increase rigidity.
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.
