Description
Technical field
The present invention relates to a kind of road sweeper special-purpose member, specifically a kind of special fan realizing ground refuse and collect on road sweeper.
Background technology
Road sweeper is the new and effective cleaning equipment integrating road cleaning, garbage reclamation and transport, its exploitation and application have promoted the development of road sweeper greatly, along with the market demand, road sweeper also develops into current various ways from single pure sweeping, and product newly energy and quality improves rapidly.At present, conventional road sweeper used is generally brush brush and comprehensive mode drawn by blower fan, such brush brush formula road sweeper has following shortcoming: one, cause because fan design is unreasonable, and this kind equipment noise is comparatively large, and sweeping efficiency is low; Two, blower interior install pipeline is unreasonable, causes air-flow in operation process, and the resistance be subject to is comparatively large and produce vortex phenomenon off-energy comparatively greatly, and the suction therefore produced is less, and functional performance is poor.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of special fan for road sweeper is provided, structure is simple, noise is low, by accurately arranging blower interior assembly and optimizing blower fan runner, make the smooth fluid flow in runner, more meet the actual runner state of air-flow in runner, reduce to cause loss because of eddy current, thus improve fan efficiency.
The present invention is the deficiency solved the problems of the technologies described above, the technical scheme adopted is: a kind of special fan for road sweeper, comprise fan casing, be arranged on the impeller in fan casing, be arranged on the air inlet on fan casing, import airduct, noise damper, main shaft, for the bearing support of supports main shaft, bearing and the support for supporting whole blower fan, one end of main shaft is connected with impeller, the other end is by the motor driven of belt pulley by road sweeper, blower fan entirety is fixed in road-cleaning compartment by support, import airduct is positioned at car bottom, its one end is connected with air inlet, the sucker of other end road sweeper connects, noise damper one end is installed on fan casing air outlet place, the other end is worn a car body top and is led to air.
Described impeller is made up of impeller front disc, impeller blade, impeller hub disk, and impeller blade is forward-type blade.
The present invention, the tapered structure of described impeller front disc; The tapered structure of the air inlet corresponding with impeller front disc.
Described main shaft is arranged in bearing support by two bearings, and bearing support adopts monolithic construction, ensures the concentricity of two bearings, and bearing adopts grease lubrication.
The invention has the beneficial effects as follows:
In one, this equipment, air inlet and impeller front disc design are taper, fan impeller blade is forward-type blade, blower interior assembly is accurately set and optimizes blower fan runner, make the smooth fluid flow in runner, more meet the actual runner state of air-flow in runner, reduce to cause loss because of eddy current, thus improve fan efficiency, and structure is simple, noise is lower; Secondly the air quantity of blower fan generation is to overcome whole system resistance of pipe system, makes air when sucker place formation certain flow rate enters pipeline, produces certain suction, drive ground refuse to enter compartment together, to reach the object of collecting ground refuse, and cleaning ground.
Two, blower fan adopts motor driven, according to ground particulate size, can control rotation speed of fan flexibly, changes blower fan suction, to be applicable to the demand of Different Ground situation, while guarantee reaches cleaning effect, reduces fan energy consumption.
Three, this bearing fan adopts Contiuum type bearing support, to ensure the concentricity of two bearings, improves bearing application life; This fan bearing adopts deep groove ball bearing, and adopts grease lubrication, can prevent bearing support leakage of oil, with the addition of enough greases when mounted, can long-term non-maintaining safe operation.
Four, road sweeper is mainly used in arterial highway, and the road-cleanings such as municipal administration and airfield pavement, uptown, park, belong to the place of densely populated place.Blower fan-matched sound absorber, effectively can reduce the noise that fan operation is, reduce the noise pollution to surrounding enviroment.
Five, blower fan overall structure is the particular design done according to the particular surroundings in compartment, under the prerequisite of actual functional capability, reduces the overall structure size of blower fan to greatest extent, and is equipped with corresponding import airduct, convenient installation.
Six, adopt special fabrication processes, blade uses blanking die blanking, and each blade will be weighed, and selects the blade within one group of weight difference 0.3kg, and use the staggered method be symmetrically welded, speed of welding electric current all requires identical.Welding deformation amount of vane is controlled to minimum.In process, ensure unifying datum, and use moulds of industrial equipment to control its unification.The balance quality of G1 is reached during impeller balance.The vibration values of rectification campaign machine when running up is made to reach below 3mm/s.
