Abstract
The utility model relates to an efficient centrifugal ventilator blade structure and belongs to the technical filed of fans. The technical scheme is as follows: the structure comprises blades (1), a wheel disk (2), a wheel hub strengthening cone (3) and a wheel hub (4); the wheel hub (4) is arranged at the center of the wheel disk (2), the wheel hub strengthening cone (3) is arranged outside the wheel hub (4) and a plurality of blades (1) are arranged at the wheel disk (2) and the wheel hub strengthening cone (3); the sections of the blades (1) are of a single-plate structure in which an arc is connected with a straight line; the front part of the single-plate structure is the arc-shaped line and the rear part of the single-plate structure is the straight line; and the blades are backward blades. By virtue of proper dimensional combination of the arced part and straight line part of each blades of the utility model, the inlet installing angel and outlet installing angle of the blades reach more reasonable values and are in match with an arc-conical wheel cover and the wheel disk (2) with the wheel hub strengthening cone (3) (rectification) and sawtooth-shaped edge, loss of air current in a blade channel is less in the operating section of the fan, thereby enabling the fan to be more efficient. The blade structure has the characteristics of simple blade shape, easiness for processing and manufacturing, low production cost and the like.
Description
Technical field
The utility model relates to a kind of blade structure of centrifugal blower efficiently, belongs to the blower fan technical field.
Background technique
Impeller is the core component of ventilator, and its structure, geometrical shape, size, lobe numbers and accuracy of manufacturing have very big influence to the performance of ventilator.Blade is the critical piece in the impeller, is the most important thing that is related to fan performance.The fan performance major parameter has flow, pressure, efficient, power etc.The structure of blade is that blower fan obtains high efficiency vital factor.The centrifugal blower blade structure of background technique is unreasonable, and efficient is undesirable, and the manufacturing difficulty is big, and cost is high.
The model utility content
The purpose of the utility model provides a kind of blade structure of centrifugal blower efficiently, raises the efficiency, and manufacturing is easy, and cost is low, solves the problems referred to above that background technique exists.
The technological scheme of the utility model is:
A kind of blade structure of centrifugal blower efficiently comprises blade, wheel disc, wheel hub conical stiffener, wheel hub, and wheel hub is arranged on wheel disk center; Wheel hub is provided with the wheel hub conical stiffener outward; Several blades are arranged on wheel disc and the wheel hub conical stiffener, and said blade profile is the one-board structure that circular arc is connected with straight line, and the front portion is the circular arc molded lines; The rear portion is the straight line molded lines, is backward inclined blade.
Wheel disc is a sawtooth pattern outer rim structure, is provided with wheel cap, and wheel cap is the tapered wheel cap of arc, and blade is whole stamping forming blade, and the tapered wheel cap of the top of blade and arc joins, and bottom and wheel hub conical stiffener and wheel disc link.
The good effect of the utility model is: blade pass is crossed the appropriate combination on the size of circular arc portion and straight section; Make blade stagger angle and exit installation angle all reach comparatively rational numerical; Cooperate tapered wheel cap of arc and the wheel disc that has wheel hub conical stiffener (rectification) and sawtooth pattern outer rim again; The loss that the air-flow that makes Ye Daonei produces in blower fan work interval is less, makes blower fan obtain higher efficient, and efficient district broadness comparatively; The utlity model has characteristics such as blade shape is simple, manufacturing is easy, cost of production is low.
