Background technique
Centrifugal blower is the principle that potential energy is converted to according to kinetic energy, is accelerated gas using high-speed rotating impeller, then
Slow down, change flow direction, kinetic energy is made to be converted into potential energy.
Centrifugal blower is widely applied in fields such as metallurgy, steel, chemical industry and building materials, but due to the running environment of centrifugal blower
Compare severe, impeller is easily worn breaking-up, and safety accident is even resulted in when serious.The most easily worn position of impeller be blade into
Gas end, vane inlet are close to the position of the blade of mid-game position and mid-game and the working face weld seam of blade.
In order to improve the wear-resisting property of blade, two methods are mainly used in the prior art: 1) using wear-resisting wlding in leaf
Piece air inlet end continuously or discontinuously build-up wear-resistant material, although the processing method can guarantee that draught fan impeller steadily be transported in the short time
Row, as runing time lengthens, wearing layer can sharply wear the effect for not having protection blade；2) in original general steel plate blade
Upper plug welding or bolt fix one layer of wearing plate, although the processing method can guarantee impeller longtime running, it is greatly increased
Impeller weight increases operation power, influences fan safe operation, and furthermore the width of wearing plate is less than width of blade, works as dust-laden
When measuring bigger, what the place that blade is not covered by wearing plate was still easy to be worn, therefore, using above two method
The blade of processing has been difficult to meet the needs of user.
However in view of the deficiencies of the prior art, a kind of design is reasonable, structure is simple, wear-resisting property it is necessary to develop by developer
Good, long service life, significantly reduces impeller overall weight, reduce impeller operation power and security performance it is high for from
The abrasion proof impeller of heart blower.
