Abstract
The utility model relates to the technical field of fans, in particular to an insertion-type fan. The wing-type insertion-type fan comprises an insertion-type fan main body comprising a fan outer shell. An impeller is arranged in the fan outer shell, blades are arranged on the impeller, and the blades are wing-type blades. Due to adoption of the wing-type blades, radian of the front ends of the blades enables airflow to be separated and accelerated along the backs and the tops of the blades when the airflow enters the blades, and turbulent flow is not generated at the front ends of the blades relative to straight-plate blades; meanwhile, when the airflow leaves tails of the blades, two streams of airflow meet at the tails of the blades slowly and the turbulent flow is not generated either, and energy loss is reduced; and meanwhile, noise occurring when the turbulent flow is produced due to collision of the airflow is eliminated, and high efficiency and low noise are achieved on the whole.
Description
Technical field
The utility model relates to the blower fan technical field, relates in particular to a kind of plug-in type flow fan.
Background technique
Year, the development of automobile industry has driven the development of related industry.In the industry relevant to automobile industry, as vehicle spray painting industry, oven dry industry, dehumidifying industry, all can use the plug-in type blower fan.The plug-in type blower fan that uses in these industries, often continuous running in long-term 24 hours, so the efficient of plug-in type blower fan and power consumption can directly affect the productivity effect of applying unit.
But existing plug-in type blower fan mostly is greatly the blower fan of straight-plate-type hypsokinesis blade, the conventional plug-in type blower fan of the manufacturer production such as, Chinese Shanghai general such as Singapore KRUGER, Chinese Shanghai Dehui.This kind draught fan impeller is the hypsokinesis prismatic blade, and impeller band tapering shroud, and design is backward and efficient is low.And blade quantity is 8 blades or 10 blades, angle and the undesirable efficient that affects of camber design.The air intake horn mouth is compacting simultaneously, the horn mouth depth as shallow, and it is large that the air intake mill is examined coefficient, and high at horn mouth and impeller stack place turbulence scale, energy consumption is large.Therefore there is very large defective in existing plug-in type blower fan aspect efficient, develop a kind of high static pressure for this reason, high efficiency wing blade plug-in type blower fan is imperative.
The model utility content
The purpose of this utility model is, a kind of wing blade plug-in type blower fan is provided, and solves above technical problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Wing blade plug-in type blower fan comprises a plug-in type fan main body, and described plug-in type fan main body comprises a flow blower casing, is provided with an impeller in described flow blower casing, it is characterized in that, described impeller is provided with blade, and described blade is wing blades.
Because blade is wing blade, when the radian of blade front end makes air-flow enter blade, air-flow is along vacuum side of blade and the separated acceleration of end face, with respect to straight blade, do not produce turbulent flow at the blade front end, two strands of air-flows meet gently and also do not produce turbulent flow at the blade afterbody when air-flow leaves the blade afterbody simultaneously, thereby when reducing energy loss the place to go because air-flow bumps against the noise that occurs when producing turbulent flow, integral body realizes high efficiency, low noise.
The number of described blade is the 8-12 sheet, is preferably 9, and 9 blades equidistantly are welded on the shroud and hub disk of described impeller.The design proposal of 9 blades is by the classical CFD cfdrc of Belgium, utilize two two dimensional surfaces intersection superposition calculations to simulate fluid in the interlobate three-dimensional rotation flow field of impeller, the calculation Design optimization, the utility model is after adopting 9 blades, had higher efficient, lower turbulent flow.Because blade and shroud and hub disk are full welding, realized high-strength characteristic, guaranteed that impeller can reach the above rotating speed of 4000RPM, makes blower fan can reach the highest static pressure 3000PA.
Described flow blower casing is provided with an air intake horn mouth, and described air intake horn mouth is that the place ahead bore is greater than the ring body of rear bore.Described air intake horn mouth is outstanding molded the in full accord of the horn mouth hyperboloid molded line after processing and design that guaranteed of complete series full automatic mechanical one, guarantee simultaneously material in the molded line cross section consistency of thickness everywhere.Described air intake horn mouth is preferably the air intake horn mouth that steel plate is made, and can make like this spinning process meticulous steadily, and the spinning surfacing is fine and smooth.In guaranteed performance, aesthetic in appearance.
Described impeller is the impeller that aluminum-magnesium alloy is made.Described wing blades adopts the wing blade of hollow machine, and described blade is provided with stiffening rib.The wing blade of hollow machine can effectively reduce the impeller overall weight, reduce rotary inertia, thereby reaches the purpose that reduces energy consumption.Described stiffening rib adopts crisscross stiffening rib, is convenient to improve the strength and stiffness of blade.Adopt the wing twisted shape, aeroperformance is good, and efficient district is broad, and energy-saving effect is remarkable.
Described shroud is the reinforced shroud of the outer astragal arc of inner ring, and reinforced shroud can make impeller have more wide in range blade area to carry air quantity, with under rotating speed, can guarantee to export more air quantity and pressure, thereby raise the efficiency.
The center of described impeller connects a rotating shaft, and described rotating shaft connects a drive motor by a driving mechanism, the flexibility of installing to improve drive motor.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, wing blade plug-in type blower fan comprises a plug-in type fan main body.The plug-in type fan main body comprises a flow blower casing, is provided with an impeller 1 in flow blower casing, and impeller 1 is provided with blade 2, and blade 2 is wing blades.Because blade is wing blade, when the radian of blade front end makes air-flow enter blade 2, air-flow is along blade 2 back sides and the separated acceleration of end face, with respect to straight blade, do not produce turbulent flow at the blade front end, two strands of air-flows meet gently and also do not produce turbulent flow at the blade afterbody when air-flow leaves the blade afterbody simultaneously, thereby when reducing energy loss the place to go because air-flow bumps against the noise that occurs when producing turbulent flow, integral body realizes high efficiency, low noise.
The number of blade 2 is the 8-12 sheet, is preferably 9, and 9 blades 2 equidistantly weld on the shroud and hub disk of impeller 1.The design proposal of 9 blades 2 is by the classical CFD cfdrc of Belgium, utilize two two dimensional surfaces to intersect superposition calculations and simulate fluid in the three-dimensional rotation flow field of 2, the blade of impeller 1, the calculation Design optimization, the utility model is after adopting 9 blades 2, had higher efficient, lower turbulent flow.Because blade 2 and shroud and hub disk are full welding, realized high-strength characteristic, guaranteed that impeller 1 can reach the above rotating speed of 4000RPM, makes blower fan can reach the highest static pressure 3000PA.
