The above technical scheme is adopted in the utility model, establish the water conservancy diversion screen panel on the frame of stator, during the rotatory axial air supply of flabellum, the static pressure is changed into through the conversion of water conservancy diversion screen panel to the dynamic pressure that the air current produced, reduces the disturbance of air current, can make the fan little at operation in-process noise, and the vibration is low, and application scope is wider.
In the flow guide screen cover fan, the end surface of the flow guide screen cover is provided with the buckle, and the buckle is buckled on the outer frame. Through the buckle, the water conservancy diversion screen panel can be dismantled with the frame and be connected, can make things convenient for the water conservancy diversion screen panel of quick replacement different grade type, realizes different conversion function, convenient to use.
In the diversion net cover fan, the diversion net cover comprises the outer ring and the inner ring, and a plurality of diversion strips are uniformly distributed between the outer ring and the inner ring. The amount of wind that the flabellum was carried, when the water conservancy diversion screen panel, through the guide of a plurality of water conservancy diversion strips for the air current that flows from the water conservancy diversion screen panel has regularity, becomes more dynamic pressure into static pressure, and the amount of wind becomes the output at the uniform velocity, thereby plays the effect that reduces the turbulent flow, reduces the fan noise.
The stator of the diversion mesh enclosure fan comprises an outer frame, a wire frame and a stator iron core, wherein the outer frame axially extends to form a hollow cavity, the wire frame is arranged on the periphery of the hollow cavity, and the stator iron core is arranged on the wire frame. When the stator iron core is electrified, a rotating magnetic field is generated to drive the rotor to rotate, and when the rotor rotates, the fan blades are driven to rotate to supply air.
The blades of the diversion net cover fan comprise a fan frame and the blades, and the blades are integrally formed on the fan frame.
In the diversion mesh enclosure fan, the rotor comprises the rotor core, the rotor core is arranged on the inner side of the fan frame and surrounds the stator core, and the fan frame is rotatably arranged in the hollow cavity through the shaft core. The rotor core rotates when the stator core generates a rotating magnetic field, and the rotor core is arranged on the fan frame to drive the fan frame to rotate, so that the blades in the fan frame stir airflow to supply air.
In the flow guide mesh enclosure fan, the hollow cavity is internally provided with the bearing, and the bearing is sleeved on the shaft core. The bearing supports the shaft core to rotate in the hollow cavity.
The utility model discloses the beneficial effect who gains is: by adding the diversion net cover, dynamic pressure generated by the fan blades during rotating air supply can be converted into more static pressure, turbulence is reduced, and noise of the fan in operation is reduced.
