Abstract
A kind of centrifugal blower fan blade wheel is the utility model is related to, there is disk and impeller lower wall on impeller；Multiple blades are equipped between the impeller front disc and impeller hub disk；Air outlet is formed between adjacent blades；Disk and/or impeller lower wall are equipped with multiple balance adjustment grooves for being used to fill balance mud along pivot center circle distribution on the impeller.The utility model eliminates the use of balance clamp, uses balance mud instead, and security is greatly improved, while the noise also effectively reduced.The Position Design of the utility model balance adjustment groove so that dynamic balancing regulating effect is more preferable.
Description
Technical field
A kind of impeller is the utility model is related to, more particularly to a kind of centrifugal blower fan blade wheel.
Background technology
Centrifugal blower is by the mechanical energy of input, heightens gas pressure and supplies gas side by side the machinery of body, it is a kind of driven
Fluid machinery.Centrifugal blower is mainly used for axial flow becoming circumferentially air-flow, and the impeller of centrifugal blower is exactly to change gas
Flow the critical component in direction.With the continuous improvement of change and the user demand of use environment, centrifugal blower needs the effect of higher
Rate, lower noise and more preferable security.
Existing centrifugal blower needs to do dynamic balance running to impeller to ensure the effect of efficient stable when dispatching from the factory,
And it is adjusted by balance clamp.With use, balance clamp easily departs from impeller, so as to cause security risk.Balance at the same time
Folder can not ensure integraty with impeller, therefore the presence of balance clamp will also result in certain noise.
Utility model content
The purpose of this utility model is to provide a kind of safe, low noise, the good centrifugal blower of dynamic balancing regulating effect
Impeller.
Realizing the technical solution of the utility model aim is：The utility model has disk and impeller lower wall on impeller；It is described
Multiple blades are equipped between impeller front disc and impeller hub disk；Air outlet is formed between adjacent blades；Disk and/or leaf on the impeller
Take turns lower wall and be equipped with multiple balance adjustment grooves for being used to fill balance mud along pivot center circle distribution.
Above-mentioned balance adjustment groove is arranged on the outer ring of impeller front disc and/or impeller hub disk and at air outlet.
As an optimization, disk and/or impeller lower wall are equipped with annular groove on above-mentioned impeller；Along pivot center in the annular groove
Multiple partitions are distributed with even circumferential；Annular groove is separated into multiple balance adjustment grooves by the partition.
Above-mentioned impeller front disc and/or impeller hub disk are equally spaced equipped with multiple along pivot center circumference, and for representing
The angle mark of current location angle value.
Adjacent angular mark is separated by 45 degree of angles.
The ratio of above-mentioned outlet air open height b2 and impeller outer diameter D2 is 0.22~0.26.Wherein optimum ratio is 0.24.
The utility model has positive effect：(1) the utility model eliminates balance clamp, avoids because balance clamp departs from
Security risk caused by and, while it also avoid noise problem caused by balance clamp resonance；
(2) balance adjustment groove is positioned close at air outlet by the utility model, according to centrifugal principle, can be conducive to dynamic flat
The adjusting of weighing apparatus；
(3) balance adjustment groove by being separated again in annular groove, greatly increases balance adjustment groove in the utility model
Quantity, further beneficial to dynamically balanced adjusting；
(4) the utility model is identified by angle, further improves the convenient degree of dynamic balancing adjusting.
