Description
Technical field
The utility model relates to a kind of centrifugal blower.
Background technique
Blower fan is generally divided into and is divided into centrifugal blower and axial-flow blower two kinds by air motion direction, and described centrifugal blower air stream axle is compressed after sailing draught fan impeller under centrifugal action, mainly radially flows.
Most centrifugal blower, enters wind wheel front to entanglement at the wind of the formation at wind inlet place, in many ways aweather easily cancels each other or weakens wind-force, and then reduces working efficiency, and in many ways aweather passing wind wheel can form eddy current simultaneously, produces noise; And wind-collection cover installation and removal are inconvenient; When centrifugal blower runs, vibrations are large, and stationary performance is poor; In rotating shaft rotary course, motor easily generates heat, and heat dissipation rate is slow, easily damages motor.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of centrifugal blower.Its working efficiency is not high, fragile and noise is little.
For achieving the above object, the technical solution adopted in the utility model is: it comprises base, be located at the motor on base and the housing being positioned at motor left end, described housing comprises upper shell and lower shell body, housing left end is provided with wind inlet, wind inlet place is provided with wind-collection cover, and described housing upper end is provided with exhaust outlet; Be provided with a cooling between the right wall of described housing and motor to take turns, the outside sheathed fixing frame of described cooling wheel, this fixing frame one end is connected with the right wall of shell, the fixing frame the other end is connected with motor, described cooling wheel and fixing frame are all located in described rotating shaft, and in described rotating shaft, corresponding cooling wheel place is provided with to prevent from lowering the temperature and takes turns the position limit pin of movement; Described wind-collection cover one end is connected with wind inlet edge, the wind-collection cover the other end stretches in wind wheel and forms break-in road with wind wheel wind inlet end, wind-collection cover comprises upper outlet body and is located at the lower cover of upper outlet body lower end, upper outlet body lower edge place is provided with projection, and lower cover upper edge place has with upper outlet body corresponding part the groove matched with projection; Described base comprises vibration damper and assembly department, and described vibration damper top is provided with bolt, and described assembly department is provided with groove, and described bolt fixes with nut through after groove.
Further, described assembly department, for be welded by channel-section steel, is provided with stiffening rib in described channel-section steel.
Further, described assembly department is rectangular, and described groove is arranged on formation and installs on two channel-section steels on minister limit.
Preferably, three vibration dampers are provided with in described every bar groove.
The utility model has following beneficial effect: arrange damping base, reduces vibrations during fan operation, and stationary performance is good; Be provided with break-in road, can the direction of the more wind of postive direction entanglement, make it enter wind wheel towards same direction, avoid because in many ways aweather cancelling each other or weakening wind-force and reduce working efficiency, also avoid in many ways aweather passing wind wheel simultaneously and form eddy current, produce noise; And wind-collection cover is arranged to Split type structure, be easy for installation and removal.Cooling wheel is set, strengthens the cooling-down effect of motor, make its service time longer.
Vibration damper can slide easily in groove, and after adjusting to suitable position, then fastening nut can realize again fixing.When therefore assembling at the scene, user suitably can change the position of vibration damper as required, makes uniform force between each vibration damper, thus avoids occurring because some vibration damper is stressed excessive and damage.Eliminate calculating base center of gravity simultaneously and obtain this step of lead to the hole site, simplify design process.
