Abstract
The utility model discloses a double-way admission type centrifugal air-blower which can enhance the blowing pressure, comprises a machine base, a left bearing, a left inlet, a left impeller, an outlet, a right impeller, a right inlet, a right bearing, a volute casing, a coupling, and a rotation axis. Wherein the left bearing is supported by the left bearing base and fixed on the left of the machine base, the right bearing is supported by the right bearing base and fixed on the right of the machine base, the rotation axis is supported by the left bearing and the right bearing, the volute casing is arranged between the left bearing and the right bearing, the left and right impellers are arranged in the volute casing and fixed on the rotation axis, the impeller is composed of a rear chassis of the impeller and the procline vanes, the procline vanes are evenly fixed on the rear chassis of the impeller. The arc supercharging vane is arranged between the procline vanes and evenly interval arranged along the rear chassis edge of the impeller, which vane is fixed on the rear chassis of the impeller to enable the outlet air pressure higher, can meet the actual requirements of the scene.
Description
Technical field:
The utility model relates to a kind of bidirectional air inlet type centrifugal blower that can improve blast pressure.
Background technique:
Bidirectional air inlet type formula centrifugal blower mainly is the high speed rotating that relies on left and right impeller, makes air under action of centrifugal force, is discharged for stove wind by exhaust outlet.Present bidirectional air inlet type centrifugal blower mainly is made of support, left bearing, left intake grill, lobus sinister wheel, air outlet, lobus dexter wheel, right intake grill, right bearing, volute casing, coupling, rotatingshaft etc., the blade of impeller is generally single garden arc or lineal shape, blade is welded on the impeller hub disk, though this blade has good moulding process, but pneumatic overall target is not fine, blast is lower under the kindred circumstances, can not satisfy field demand.
The model utility content:
The purpose of this utility model provides a kind of simple in structure, blast and the higher bidirectional air inlet type centrifugal blower of efficient.
To achieve these goals, the utility model comprises: support, left bearing, left side suction port, the lobus sinister wheel, the air outlet, the lobus dexter wheel, right suction port, right bearing, volute casing, coupling, rotatingshaft, left bearing is supported and is fixed on the left part of support by left shaft holder, right bearing is by the right bearing seat supports and be fixed on the right part of support, rotatingshaft is supported by left bearing and right bearing, volute casing is positioned in the middle of left bearing and the right bearing, lobus sinister wheel and lobus dexter wheel are positioned at volute casing and are fixed on the rotatingshaft, impeller is made of impeller hub disk and FC blade, the FC blade evenly is fixed on the impeller hub disk, it is evenly to be arranged at intervals with arc supercharging blade at plate edge between the FC blade and behind the impeller, and arc supercharging leaf is fixed on the impeller hub disk.Left and right like this impeller because arc supercharging blade makes the gas pressure of air outlet higher to the promotion pressurization of gas, can satisfy on-the-spot actual requirement in the high speed rotating process, have simple in structure, blast and efficient than characteristics such as height.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a blade wheel structure schematic representation of the present utility model.
Embodiment:
As seen from Figure 1, Figure 2, the utility model comprises: support 1, left bearing 3, left suction port 4, lobus sinister wheel 6, air outlet 7, lobus dexter wheel 8, right suction port 11, right bearing 12, volute casing 9, coupling 13, rotatingshaft 14.Left bearing 3 supports and is fixed on the left part of support 1 by left shaft holder 2, and right bearing 12 supports and be fixed on the right part of support 1 by right bearing seat 15, and rotatingshaft 14 is supported by left bearing 3 and right bearing 12.Right-hand member at rotatingshaft 14 is provided with a coupling 13, is used for being connected of rotatingshaft and motor rotary shaft.Volute casing 9 is positioned in the middle of left bearing 3 and the right bearing 12, lobus sinister wheel 6 and lobus dexter wheel 8 are positioned at volute casing 9 and are fixed on the rotatingshaft 14, air outlet 7 is positioned at the top of volute casing 9, and left suction port 4 is positioned at the left part of lobus sinister wheel 6, and right suction port 11 is positioned at the right part of lobus dexter wheel 8.In order to guarantee that air inlet reduces noise smoothly, left suction port 4 is provided with left slip ring 5, and right suction port 11 is provided with right slip ring 10.Impeller is made of impeller hub disk 18 and serpentine FC blade 16, FC blade 16 evenly is weldingly fixed on the impeller hub disk 18, between FC blade 16 and along impeller hub disk 18 edges, evenly be arranged at intervals with arc supercharging blade 17, arc supercharging leaf 17 is weldingly fixed on the impeller hub disk 18, the length of arc supercharging blade 17 can be provided with as required, generally FC blade 16 length 1/3 to 1/4 between.During installation, serpentine FC blade 16 bending directions on lobus sinister wheel 6 and the lobus dexter wheel 8 should be opposite, to guarantee the air inlet simultaneously of left and right suction port.
