The model utility content
In order to solve the deficiencies in the prior art, the utility model provides a kind of and utilizes blower fan self power and do not need the structure of the air-cooled bearing of exterior power, mainly solves the problem that existing fan bearing temperature raises easily, and forms one with blower fan.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of fan bearing air cooling equipment, comprise main shaft, frame, impeller and bearing unit, described main shaft is installed on the frame by bearing unit, installed inside has impeller on the described main shaft, it is characterized in that, also comprise a cover body, described cover body be installed on the frame of bearing unit periphery and by coat and bearing unit between form an air channel, the inside and outside frame that connects in described air channel is inside and outside.
Described cover body comprises semi-circle housing and rack sleeve, semicircle housing wherein is coated on the periphery of bearing unit, rack sleeve is nested with the extension part in the main shaft outside, the sectional area of the air-flow path between its rack sleeve and the main shaft forms the gas shock effect less than the sectional area of semi-circle housing and bearing unit.
A kind of cabinet type fire-fighting blower fan, comprise casing, impeller, main shaft, bearing unit, the air intake flange, outlet air flange and drive motor, wherein, described main shaft is installed on the frame by bearing unit, installed inside has impeller on the described main shaft, described casing forms a cavity by the mode that coats impeller, described air intake flange and outlet air flange are arranged on the both sides, front and back of casing, and casing is installed on the frame, it is characterized in that, also comprise a cover body, described cover body be installed on the frame of bearing unit periphery and by coat and bearing unit between form an air channel, air inlet duct is assisted in inside and outside frame and enclosure interior and the outside of connecting, described air channel, takes away the heat of bearing unit in air current flow.
Described cover body comprises semi-circle housing and rack sleeve, semicircle housing wherein is coated on the periphery of bearing unit, rack sleeve is nested with the extension part in the main shaft outside, the sectional area of the air-flow path between its rack sleeve and the main shaft forms the gas shock effect less than the sectional area of semi-circle housing and bearing unit.
The beneficial effects of the utility model are: by a cover body is set in frame, form an air channel between cover body and the bearing unit, air-flow by this external world, air channel can enter enclosure interior, form a substantial auxiliary air channel, can take away most bearing in the time of air current flow because the heat that rolls and produce, reduce the temperature of bearing unit, form reasonable air cooling effect.The power that whole process utilizes the impeller rotation to produce fully carries out air-cooled, and blower fan main shaft and impeller position are not done any adjustment, can the intensity of main shaft and impeller not had any impact.
