Uneven is attached on impeller, gradually destroys the dynamic balancing of blower fan, is gradually increased bear vibration, once vibration reaches blower fan
During the maximum 11mm/s of permission（The maximum permissible value represented with amplitude is as follows）, blower fan must shut down repairing（Remove dust
Accumulation, reforms dynamic balancing）.Because being at this moment breakneck, user ten million can not use by force.In the close danger of fan vibration
During the value of danger, the meeting for having vibration measuring instrument is alarmed.Blower fan is China to the custom of gas compression and gas conveying machinery abbreviation, usual institute
The blower fan said includes：Ventilation blower, air blower, wind-driven generator.Gas compression and gas conveying machinery are the mechanical energy rotation
Be converted to gas pressure energy and kinetic energy, and the machinery that gas is transferred out.
However, traditional blower fan, during continuous use, bearing can cause temperature to raise because of prolonged friction,
Temperature is too high to damage bearing, the existing typically no heat dissipation design of fan bearing.
The content of the invention
The purpose of this utility model be to provide a kind of new main shaft can heat radiating type blower fan, to solve in above-mentioned background technology
The traditional blower fan proposed is during continuous use, and bearing can cause temperature to raise because of prolonged friction, temperature mistake
Height can damage bearing, the existing typically no heat dissipation design problem of fan bearing.
To achieve the above object, the utility model provides following technical scheme：A kind of new main shaft can heat radiating type blower fan, bag
Pump case is included, gas outlet is provided with above the pump case, and the bosom opening position of pump case is provided with radiating axle sleeve, it is described to dissipate
The surface of hot axle sleeve is provided with fin, and the right-hand member for the axle sleeve that radiates is provided with impeller, and the left end of the radiating axle sleeve is provided with
Belt pulley, pump bowl flange is provided with the left of the pump case, and the left side of pump case is provided with main bush on the inside of belt pulley
Set, the belt pulley, mainshaft bushing, radiating axle sleeve are connected with impeller by main shaft.
Preferably, the fin is evenly distributed on the surface of radiating axle sleeve, and fin is flake.
Preferably, the pulley rotation passes through motor and belt drive.
Preferably, the belt pulley, mainshaft bushing, radiating axle sleeve and impeller pass through main shaft synchronous axial system.
Preferably, the mainshaft bushing is bolted to connection with radiating axle sleeve.
Preferably, the pump bowl flange is bolted to connection with pump case.
Compared with prior art, the beneficial effects of the utility model are：The radiating axle sleeve in fan bearing indoor design, dissipate
Hot axle sleeve is fixed on the outside of bearing, and fin is devised on axle sleeve, and fin is passed through by bearing by the air-flow of air blower
The high temperature on surface is taken away, and reaches the purpose for reducing bearing temperature, extends the service life of fan bearing.
