Description
Technical field
The utility model is related to a kind of deduster blower fan, more specifically to a kind of deduster blower fan main shaft.
Background technology
Existing deduster uses solid shafting with blower fan main shaft, because solid shafting is heavy, not only wastes substantial amounts of material
Material, and blower fan rotary inertia is big, and starting current is high, and necessary electromotor power also increases, and increases the use cost of centrifugal blower.
In addition, centrifugal blower fan blade wheel is positioned with main shaft by way of round nut and stop washer and the shaft shoulder, this mode
It is more suitable for small-sized fan, but for large fan, because the main shaft of large fan is thicker than the main shaft of small-sized fan, if needing
On the main shaft that centrifugal blower fan blade wheel is navigated to the large fan, then very big round nut and stop washer is needed.Using
This mode, cost that is not only complicated, improving production packing ring and nut, and manufacture also inconvenient, another round nut makes
The easy corrosion in, will so cause to dismount very inconvenient during impeller.
