Abstract
The utility model relates to the technical field of a ventilator, in particular to an integral impeller for a ventilator. The existing ventilator has the defect that the angles of the impellers are inaccurate owing to processing inaccuracy, inaccuracy in measuring the vane installation angle, error caused by electrical welding thermal distortion, processing skills level of workers and so on, thereby the intensity of the ventilator is lowered, the noise becomes louder, and the working efficiency is reduced with enormous electrical energy consumption and high maintenance. In order to overcome the defects, the utility model has the technical scheme as follows: the integral impeller for a ventilator comprises vanes, a wheel hub, a spoke, a bearing bush; wherein, the vanes, the wheel hub, the spoke and the bearing bush are connected and cast into a whole. The integral impeller for a ventilator provided by the utility model is cast at one time, without the problems occurred in the existing impeller processing such as insufficient soldering, untight riveting and so on. Besides, the ventilator has the advantages of high intensity, high security, simple manufacturing technique and low production cost.
Description
Technical field
The utility model relates to the ventilator technical field, is specifically related to a kind of blower fan integral wheel.
Background technique
The energy consumption of ventilator, noise and its core component---fan blade has direct relation, and blade technology has determined the final properties of ventilator.And the tiny deviation that produces on the Placement of ventilating vane and wheel hub, setting angle and the processing method process, performance that all can fan is brought significant impact.
The fan blade of existing ventilator is that each sheet fan blade is processed separately, gold is pulled in employing, welding, processing mode monolithic moulding such as die casting, because existing high blast, high every blade of air quantity ventilator fan and adjacent blades are all having overlapping along impeller shaft to direction projection, traditional die processing method can't be processed integral wheel, so blower fan manufacturer all adopts the independent moulding of blade to be fixed on the wheel hub by rivet welding technology more at present, this processing method is because wheel hub and blade separate machined, when carrying out gang welding, be subjected to machining error, blade installation angle measurement error, the electric welding thermal deformation errors, many cause influences such as workman's processing technique level can cause deformable blade, the blade angle inaccuracy, thus make the blower fan reduction in strength, it is big that noise becomes, inefficiency, power consumption is huge and maintenance rate is high.
Summary of the invention
The utility model provides a kind of precision height, intensity is big, efficient is high, maintenance rate is low blower fan integral wheel.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of blower fan integral wheel comprises blade 1, wheel hub 2, spoke 3, bearing housing 4, and its special way is: the integral body that described blade 1, wheel hub 2, spoke 3, bearing housing 4 form for the once casting that links together.
The blade that any one blade of above-mentioned impeller is adjacent is all having overlapping along impeller shaft to direction projection.
Above-mentioned blade 1 is the curved three-dimensional twisted blade of combination orthogonal type of plunderring.
The end projection and the blade 1 root projection angle of cut are acute angle relation on the above-mentioned blade 1.
Compared with prior art, advantage of the present utility model is as follows:
For casting once forms, there is not common problem in the existing Impeller Machining such as rosin joint, riveted joint are tight in the blower fan integral wheel that the utility model provides, and intensity is big, and Security is good; And manufacturing process is simple, low production cost.Adopted fan efficiency height of the present utility model, noise low, compared with similar products at home and abroad, its rated efficiency has improved 5%～10%, actual operating efficiency on average improves 35%, reduces by 10～20dB, energy saving consumption than A sound level aerodynamic noise, improve environmental condition, increase economic efficiency.
Description of drawings
Fig. 1 is the utility model overall structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, the utility model provides a kind of blower fan integral wheel, comprises blade 1, wheel hub 2, spoke 3, bearing housing 4, the integral body that described blade 1, wheel hub 2, spoke 3, bearing housing 4 form for the once casting that links together.The blade that any one blade of above-mentioned impeller is adjacent is all having overlappingly to direction projection along impeller shaft, blade 1 is the curved three-dimensional twisted blade of combination orthogonal type of plunderring, and the end projection and the blade 1 root projection angle of cut are acute angle relation on the blade 1.
The utility model has saved the medium tache in the impeller production and processing in manufacture process, the controllable degree height, and design data is lost little in course of working.Once there is not common problem in the existing Impeller Machining such as rosin joint, riveted joint are not tight in the integral wheel that forms of casting, and intensity is big, Security good and easy for installation, applicable to all kinds of blower fans.
