The utility model is the deficiency that solves the problems of the technologies described above, the technological scheme that adopts is: a kind of road sweeper special fan, comprise fan casing, be arranged on the impeller in the fan casing, be arranged on the air inlet on the fan casing, the import airduct, baffler, main shaft, the bearing support that is used for supports main shaft, bearing and be used for to support the support of whole blower fan, one end of main shaft links to each other with impeller, the other end is by the engine-driving of belt pulley by road sweeper, blower fan integral body is fixed in the road-cleaning compartment by support, the import airduct is positioned at the bottom, compartment, the one end links to each other with air inlet, the sucker of the other end road sweeper connects, baffler one end is installed on fan casing exhaust outlet place, and the other end is worn a car body top and led to atmosphere.
Described impeller is made up of impeller shroud, impeller blade, impeller hub disk, and impeller blade is the forward-type blade.
The utility model, the tapered structure of described impeller shroud; The tapered structure of the air inlet corresponding with the impeller shroud.
Described main shaft is arranged in the bearing support by two bearings, and bearing support adopts monolithic construction, guarantees the concentricity of two bearings, and bearing adopts grease lubrication.
The beneficial effects of the utility model are:
The design of air inlet and impeller shroud is taper in one, this equipment, fan impeller blade is the forward-type blade, the blower fan internal component accurately is set and optimizes the blower fan runner, make smooth and easy the flowing of fluid in the runner, more meet the actual runner state of air-flow in the runner, reduce because eddy current causes loss, thereby improve fan efficiency, and simple in structure, noise is lower; Secondly the air quantity of blower fan generation makes air when sucker place formation certain flow rate enters pipeline to overcome the whole system resistance of pipe system, produces certain suction, drives ground refuse and enters the compartment together, to reach the purpose of collecting ground refuse, cleaning ground.
Two, blower fan adopts engine-driving, can control rotation speed of fan flexibly according to the ground particulate size, changes blower fan suction, in order to be fit to the demand of Different Ground situation, reduces fan energy consumption when guaranteeing to reach cleaning effect.
Three, this bearing fan adopts integrated type bearing support, to guarantee the concentricity of two bearings, improves bearing working life; This fan bearing adopts deep groove ball bearing, and adopts grease lubrication, can prevent the bearing support leakage of oil, has added enough greases when mounted, can long-term non-maintaining safe operation.
Four, road sweeper is mainly used in arterial highway, and road-cleanings such as municipal administration and airfield pavement, uptown, park belong to personnel's places with dense.Blower fan adapted silencing apparatus can effectively reduce the noise that fan operation is, reduces the noise pollution to surrounding enviroment.
Five, the blower fan overall structure is the particular design of doing according to the particular surroundings in compartment, under the prerequisite of actual functional capability, dwindles the overall structure size of blower fan to greatest extent, and is equipped with corresponding import airduct, the convenient installation.
Six, adopt special fabrication processes, blade uses the blanking die blanking, and each blade will be weighed, and selects one group of weight and differ blade within the 0.3kg, uses the staggered method that is symmetrically welded, and the welding speed electric current all requires identical.Make welding deformation amount of vane control to minimum.In course of working, guarantee unifying datum, and use moulds of industrial equipment to control its unification.Reach the balance quality of G1 during the impeller balance.The vibration values of rectification campaign machine when running up reached below the 3mm/s.
