Abstract
The utility model belongs to high pressure centrifugal ventilator field, is specifically related to a kind of mesohigh centrifugal blower for high-pressure delivery material.A kind of mesohigh centrifugal blower for high-pressure delivery material, comprise casing, impeller, air inlet ring group, rivet, wheel hub, motor, support, flat key, axle head disk and bolt, described impeller includes shroud, hub disk, the blade be arranged on hub disk, described blade is backward inclined blade, and vane type line adopts logarithmic spiral molded line.Compare prior art, the fan performance after the utility model improves obtains larger lifting, and peak rate of flow improves 20%, total head improves 15%, and total pressure efficiency improves 15%, and energy consumption reduces by 15% simultaneously, about noise reduction 5dBA, comparatively prototype blower fan is low for overall cost.
Description
Technical field
The utility model belongs to high pressure centrifugal ventilator field, is specifically related to a kind of mesohigh centrifugal blower for high-pressure delivery material.
Background technique
9-19 Series Centrifugal ventilator is a kind of forward inclined type mesohigh centrifugal blower, is widely used in high-pressure delivery material, conveying air or non-corrosiveness, nonflammable explosive, not containing the gas of stickum, also can be used for high pressure forced ventilation.Although this serial fan pressure is higher, total pressure efficiency is lower, and energy consumption is comparatively large, but this serial fan is very wide in every profession and trade using scope, cannot be substituted in a short time, and the blower fan cost of some new models increases, Difficulty.Prototype 9-19 serial fan impeller adopts Forword vane large outlet angle to obtain higher total head, and Forword vane exists shortcomings such as total pressure efficiency is low, noise large, efficient energy conversion is lower.
Model utility content
For the technology Problems existing that above-mentioned existing 9-19 Series Centrifugal ventilator exists, the utility model improves for existing 9-19 Series Centrifugal ventilator, provides the high pressure centrifugal ventilator for high-pressure delivery material that a kind of flow is higher, total head is higher, energy consumption is lower, noise is smaller.For realizing this object, the utility model adopts following technological scheme:
A kind of mesohigh centrifugal blower for high-pressure delivery material, comprise casing, impeller, air inlet ring group, rivet, wheel hub, motor, support, flat key, axle head disk and bolt, described impeller 2 includes shroud, hub disk, the blade be arranged on hub disk, described blade is backward inclined blade, and vane type line adopts logarithmic spiral molded line.Retain casing and the air inlet ring of former centrifugal blower, be optimized impeller, original Forword vane changes backward inclined blade into, and the total head that backward inclined blade produces is less, but static pressure head portion in total head is comparatively large, and runner energy loss is little, and efficiency is higher; Vane type line adopts logarithmic spiral shape line.
Further, described hub disk is provided with attached blade.Increase attached blade and improve total head and total pressure efficiency.
Further, described blade 22 is 12.
Further, described attached blade 24 is 12.
Further, the length of described attached blade is 1/5 ~ 1/2 of described impeller diameter.
Further, the balance level of described impeller is 5.6mm/s.
To compare prior art, the beneficial effect that the utility model has: the fan performance after improvement obtains larger lifting, peak rate of flow improves 20%, total head improves 15%, and total pressure efficiency improves 15%, and energy consumption reduces by 15% simultaneously, about noise reduction 5dBA, comparatively prototype blower fan is low for overall cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is prior art blade wheel structure schematic diagram;
Fig. 3 is the utility model blade wheel structure sectional view;
Fig. 4 is the utility model blade wheel structure side view;
In figure, 1-casing, 2-impeller, 21-shroud, 22-blade, 23-hub disk, the attached blade of 24-, 3-air inlet ring group, 4-rivet, 5-wheel hub, 6-motor, 7-support, 8-flat key, 9-axle head disk, 10-bolt.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is further described.
A kind of mesohigh centrifugal blower for high-pressure delivery material, comprise casing 1, impeller 2, air inlet ring group 3, impeller 2 be fixed on wheel hub 5 by rivet 4, motor 6, support 7, flat key 8, axle head disk 9 and bolt 10, described impeller 2 includes shroud 21, hub disk 23, the molded line employing logarithmic spiral molded line backward inclined blade 22 be arranged on hub disk 23, and described hub disk 23 is provided with attached blade 24.
The quantity of described blade 22 and attached blade 24 is 12; The length of described attached blade 24 is 1/5 ~ 1/2 of described impeller 2 diameter; The balance level of described impeller (2) is 5.6mm/s.
When other parameters are identical, the centrifugal blower peak rate of flow after improvement improves 20%, and total head improves 15%, total pressure efficiency improves 15%, and energy consumption reduces by 15%, about noise reduction 5dBA simultaneously, overall cost comparatively prototype blower fan decreases, not adding users cost.
Last it is noted that above embodiment only in order to illustrate the utility model and and technological scheme described by unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement; And all do not depart from technological scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
