Abstract
The utility model discloses a parallel type centrifugal fan, which comprises a left centrifugal fan, a right centrifugal fan and an intermediate motor cavity, wherein the left centrifugal fan and the right centrifugal fan are respectively positioned on two sides of the motor cavity; a double-shaft output motor is fixed inside the motor cavity; the motor cavity is absolutely closed and not mutually communicated with a left and a right centrifugal fan casings; a left-side output shaft of the double-shaft output motor passes through the casing wall and is fixedly connected with a centrifugal impeller through a shaft sleeve; a left and a right centrifugal impellers are driven by a power system to simultaneously work; and the aims of air intake and exhaust can be achieved by changing the operation direction of the power system. With the parallel type design, the requirement for increasing the air quantity and the air pressure can be met, the work efficiency of a ventilator can be improved under the same condition and the aim of saving energy can be achieved simultaneously; and the motor cavity is absolutely closed and is not mutually communicated with the left and the right centrifugal fan casings so as to ensure that the power system is not influenced when conveying high-temperature air current or air current with corrosive media.
Description
Technical field
The utility model belongs to fan-type ventilation equipment, particularly relates to a kind of centrifugal fan equipment.
Background technique
Centrifugal blower is the principle that is converted to potential energy according to kinetic energy, utilizes the impeller of high speed rotating that gas is quickened, and slows down, changes the flow direction then, make kinetic energy convert potential energy to, gas is from axially entering impeller, and gas stream changes over radially when impeller, enters Diffuser then.In Diffuser, gas and changing flow direction cause deceleration, this decelerating effect converts kinetic energy to the pressure energy.Increased pressure mainly occurs in the impeller, and next occurs in the diffusion process.
Summary of the invention
The utility model is attempted the structural feature by existing one-stage centrifugal blower fan, by using the power assembly of two shaft blower fans, invents a kind of parallel centrifugal blower.
The parallel centrifugal blower of the utility model is to realize purpose by following technological means:
Parallel centrifugal blower has two centrifugal blowers and two shaft motor combination to form, promptly form by left centrifugal blower, right centrifugal blower and middle part motor cavity three macrostructures, left side centrifugal blower and right centrifugal blower be position and motor cavity both sides respectively, and with it by the bolt riveted fixing.Left side centrifugal blower and right centrifugal blower all are made up of housing, centrifugal impeller, slip ring and flange three part-structures.Structure characteristic with left centrifugal blower is an example, two left side shafts that go out shaft motor pass shell body wall fixedlys connected by axle sleeve with centrifugal impeller, housing right flank and centrifugal impeller laterally correspond to the intake grill position, intake grill is provided with slip ring, exhaust outlet is positioned at the horizontal rectangular opening on housing top, has flange on the exhaust outlet extension.The structure of the right centrifugal blower feature of arranging is the horizontal mirror image performance of left centrifugal blower.Described motor cavity internal fixation has two shaft motors that go out, and its outer wall is provided with terminal box, the definitely airtight not intercommunication of motor cavity and left and right sides centrifugal blower housing.Wherein said centrifugal blower housing is all spiral shaped housing mutually with common centrifugal blower.
The beneficial effect of the parallel centrifugal blower of the utility model is: two centrifugal impellers were worked simultaneously about a power system drove, and the rotation direction that changes power system reaches the purpose of air intake or air draft.The requirement that strengthens airflow pressure has been satisfied in parallel design, has under equal conditions improved the working efficiency of ventilator, has reached purpose of energy saving simultaneously; The absolute airtight not intercommunication of motor cavity and left and right sides centrifugal blower housing can guarantee that power system is unaffected when the air-flow of wind chamber conveying high temperature or band Korrosionsmedium.
