Abstract
The invention relates to a unilateral fixed bidirectional air inlet centrifugal fan. The centrifugal fan comprises a volute provided with two air inlets. A motor is fixed in the volute through a support. A vane wheel is arranged on a rotor of the motor in a sleeving mode. The support comprises a circular base, a circular adapter and at least three supporting pillars connected between the outer edge of the base and the inner edge of the adapter. The adapter is parallel to the base and is coaxially arranged with the base. The diameter of the inner edge of the adapter is greater than the diameter of the outer edge of the base. A stator of the motor is fixed to the base. The supporting pillars surround the exterior of the vane wheel and symmetrically rotate around a rotary shaft of the motor. The adapter is fixed to one end of the volute and surrounds the air inlet formed in the end, and the supporting pillars extend into the interior of the volute through the air inlet of the end where the adapter is fixed to. The base is located in the volute and does not exceed the air inlet formed in the other end of the volute. The unilateral fixed bidirectional air inlet centrifugal fan has the advantages that the installation structure that one side of the bidirectional centrifugal fan is not provided with a support is achieved through the specially designed support, and the shortage of the prior art is overcome. The unilateral fixed bidirectional air inlet centrifugal fan is simple in structure and convenient to assemble, disassemble and use.
Description
Technical field
The present invention relates to centrifugal blower technical field, particularly relate to a kind of centrifugal blower of one-sided fixing two-way air intake.
Background technique
Centrifugal blower is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the equipment of body, it is a kind of driven fluid machinery; Centrifugal blower is widely used in factory, mine, tunnel, cooling tower, vehicle, the ventilation of boats and ships and building, dust discharge and cooling; The ventilation for boiler and industrial furnace also had and air inducing.
The working principle of centrifugal blower is: centrifugal blower is the principle being converted to potential energy according to kinetic energy, utilizes the impeller of High Rotation Speed to be accelerated by gas, and the flow direction of the gas that then slows down, changes, makes kinetic energy convert potential energy to.In one-stage centrifugal blower fan, gas is from axially entering impeller, and gas flow changes over radial direction when impeller, then enters Diffuser, and in Diffuser, gas and changing flow direction causes deceleration, and this decelerating effect converts kinetic energy to pressure energy.The pressure of this air-flow increases and mainly occurs in impeller, and next occurs in diffusion process.In Multi-stage centrifugal fan, make air-flow enter next impeller with return channel, produce higher pressure.
The ordinary construction of centrifugal blower is: centrifugal fan is generally made up of casing, impeller and motor etc., centrifugal blower pattern on existing market is a lot, two-way air intake and unidirectional air intake two kinds can be divided into according to air inlet mode, unidirectional blower fan is usually one side closed, the uncovered formation intake grill of opposite side, and the stator of motor is fixed on the bottom of casing closed side; Two-way blower fan then both sides all offers intake grill, and air inlet is located at A-frame, is fixed with coupling shaft between two A-frames, and the mantle that powers on is located on described coupling shaft.
In some scenarios, propose such requirement due to concrete operating mode: need centrifugal blower can two-way air intake, but wherein side can not there is the A-frame of protrusion.And the centrifugal blower both sides of traditional two-way air intake support all must be set can fixed electrical machinery, current existing blower fan cannot meet such demand.
Summary of the invention
The object of the embodiment of the present invention is for the structural shortcoming of prior art, a kind of centrifugal blower of one-sided fixing two-way air intake is proposed, by specially designed support, achieve the unsupported mounting structure in two-way centrifugal blower side, solve the deficiencies in the prior art.
In order to reach foregoing invention object, the centrifugal blower of a kind of one-sided fixing two-way air intake that the embodiment of the present invention proposes is achieved through the following technical solutions:
A kind of centrifugal blower of one-sided fixing two-way air intake, comprise the spiral case with two relative circular intake grills, motor is fixed with by support in described spiral case, the rotating shaft of described motor is positioned on two circular intake grill center lines, the rotor of described motor is arranged with impeller, it is characterized in that: described support comprises the base of circle, the transfer panel of ring and at least three pillars be connected between base outer rim and transfer panel inner edge; Described transfer panel is parallel with base and coaxially arrange, and transfer panel inner edge diameter is greater than base external profile diameter; The stator of described motor is fixed on base, those pillars around with in described impeller outer, and around the rotating shaft Rotational Symmetry of motor; Described transfer panel is fixed on one end of spiral case and around intake grill, described pillar stretches in spiral case via the intake grill on this end, and described base is positioned at the intake grill that described spiral case does not exceed the spiral case the other end.
The quantity of described pillar is three.
Bolt between described motor stator and base.
Described base external profile diameter is the 40%-70% of transfer panel inner edge diameter.
Compared with prior art, the invention has the beneficial effects as follows: by specially designed support, achieve the unsupported mounting structure in two-way centrifugal blower side, solve the deficiencies in the prior art.Its structure is simple, is convenient to installation and removal, easy to use.
