Abstract
An energy-saving centrifugal fan is characterized in that: a motor is fixed on a volute, a motor shaft is provided with an impeller whose shaft disk is connected with a rear disk by a rivet, and a front disk is installed on the shaft disk, sixty four half-arc leaves are installed between the rear disk and the front disk, a mesh board is fixed in an air inlet by a bolt and a nut, the left end and the right end of the shaft disk of impeller are provided with a shaft shoulder washer and a shaft head washer separately, the air inlet of fan is bigger while the air outlet of fan is smaller, the impeller size is small and the space between the impeller and the shaft is reduced to make air quantity large. Since the air quantity is large and the vortex is small, the noise become small, especially the power consumption is less.
Description
Technical field
The utility model relates to a kind of energy saving centrifugal ventilator, is the equipment that is used for the high pressure forced ventilation or carries air or non-ignitibility material, belongs to the technical field of ventilator.
Background technique
The blast and the air quantity of existing centrifugal blower are less, and noise is but obviously higher, and its power consumption is also big, and the blade that impeller is installed above often is about 12; Blade quantity is few, intake grill is less, also little with the ratio of exhaust outlet, machine volume is big, but capacity is little, the eddy current effect of impeller blade is big, especially power consumption is many.
Summary of the invention
The purpose of this utility model is that a kind of energy saving centrifugal ventilator will be provided, the supporting centrifugal blower of 5.5kw motor for example, and its air pressure air flow also is not less than existing 9-19 type high pressure centrifugal ventilator.
The motor of centrifugal blower is fixed on above the volute, impeller has a reel to connect a hub disk with rivet, one shroud is housed again on the reel, the blade that 64 circular arcs are housed between the dish of front and back evenly distributes along circumference, intake grill is fixed a web plate, and end is equipped with shaft shoulder packing ring and spindle nose packing ring respectively about the reel of impeller.
The advantage of this ventilator is that blade is 64, and common blower fan has only 12 blades; Intake grill is bigger in addition, and exhaust outlet is less, and blade adopts circular arc that air quantity is increased and blast also increases, and the complete machine size is less, uses steel few; Also shortened the space between impeller and the axle in addition, made energy-saving effect remarkable, the impeller blade eddy current reduces, so the also corresponding reduction of noise.
Description of drawings
Fig. 1. the energy saving centrifugal ventilator schematic representation
Fig. 2. the impeller schematic representation
Fig. 3. the impeller side view
By Fig. 1, motor (1) is with bolt (2) and nut (3), packing ring (4) and spring washer (5) are affixed with volute (6), impeller (7) in the volute (6) is contained on the motor shaft (1), the intake grill (10) of volute (6) compresses web plate (11) and be fixed on above the end face of intake grill (10) with sunk screw (15) and flange (14), spindle nose packing ring (12) is fixed on bolt (8) and spring washer (9) on the right side of reel (21) of impeller (7), between the left side of the impeller reel (21) of impeller (7) and the motor shaft shaft shoulder packing ring (13) is housed, bolt (16), spring washer (17), packing ring (18), rubber pad (19) is fixed on the right side of volute (6), between the left side of volute (6) and motor (1) bottom surface asbestos slate (20) is housed.
By Fig. 2,3, the reel of impeller (21) middle part is a plane disc (26), left part is connected with a cylindrical body (27), right-hand member be a cone (28) and with rivet (29) with the plane disc (26) of reel (21) and impeller hub disk (30) riveted joint, impeller shroud (31) is contained in above the cone (28), totally 64 and evenly distribute along circumference of circular arc vanes (32) are housed between impeller shroud (31) and the impeller hub disk (30), the radius of blade (32) is 26mm, thickness is 1.5mm, the tangent line of the point on the tangent line of one end and the hub disk becomes 8 ° of inclinations, the tangent line of the blade the other end and A, the line that B is 2 intersects 104 °.
Embodiment
Impeller (7) need be made overspeed test, and rotating speed is 3200 rev/mins, and test period should not be less than 5 minutes.Trying fast rear blade must not have loosening phenomenon, and impeller should not have distortion yet.
This blower fan is single inhalation type, and blade can be made left-handed or dextrorotation, and the exhaust outlet angle can be made into 0 °, 45 ° 90 °, 135 °, 180 °, 225 °, 270 °, and as with power of motor 5.5kw, pressure range is 4630～5589Pa, and flow is 2590～2905m
3/ h is equivalent to 9-19 type blower fan.
By actual specific, 2 degree that per hour economize on electricity, 24 hours is 48 degree, be equivalent to 24 yuans, 720 yuan of the expenses of can economizing on electricity in month, annual by calculating 7200 yuan of the expenses of can economizing on electricity in 10 months, impeller blade is improved to 64 by 12 of common blower fans, and the big air-out of intake grill is young, and blade adopts circular arc.Impeller outer diameter is less, and shroud place intake grill is big, has shortened the space between impeller (7) blade, has played energy-conserving action.The unit external diameter is little in addition, uses steel few, and the eddy current of impeller is very little, so noise also reduces.
Claims (2)
