Abstract
The utility model discloses a rectangular low-noise centrifugal pipeline fan, which comprises a centrifugal fan the rotating shaft of which is vertically arranged, a housing the horizontal section of which is rectangular is arranged outside the centrifugal fan, the two ends of the housing, at horizontal direction of the housing, are respectively provided with an air inlet and an air outlet, the inner air inlet of the centrifugal fan is communicated with the air inlet of the housing, and the inner air outlet of the centrifugal fan is communicated with the air outlet of the housing. The rectangular low-noise centrifugal pipeline fan has simple structure, and is convenient to install and maintain. Since a motor is arranged on the outer wall of the housing, the pipeline fan of the utility model can be suitable for the high-temperature air flow transmission.
Description
Technical field
The utility model relates to the Fan Equipment field, relates in particular to a kind of low noise rectangle centrifugal pipeline blower fan.
Background technique
The centrifugal pipeline blower fan is the mechanical energy that relies on input, improve supply gas the side by side machinery of body of gas pressure, it is a kind of driven fluid machinery, mainly is to utilize the impeller of high speed rotating that gas is quickened, slow down, change the flow direction then, make kinetic energy convert potential energy (pressure) to.In the one-stage centrifugal pipeline fan, 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.In the multistage centrifugal pipeline fan, make air-flow enter next impeller with return channel, produce more high pressure.
No matter be one-stage centrifugal pipeline fan or multistage centrifugal pipeline fan, the general spirality casing structure that adopts, and adopt welding manner to finish each parts assembling more, intake grill and exhaust outlet are positioned on two different direction planes, difficulty is applied to narrow and small place, space, and because the irreqularity of its external structure, also transportation of the loading of inconvenient centrifugal blower and installation.
Summary of the invention
The utility model provide a kind of simple in structure, be convenient to installation and maintenance and can be applicable to the low noise rectangle centrifugal pipeline blower fan that high temperature gas flow is carried.
A kind of low noise rectangle centrifugal pipeline blower fan comprises the centrifugal blower that rotating shaft vertically is provided with, and described centrifugal blower is provided with the shell that the horizontal section is a rectangle outward, and the two ends on the shell substantially horizontal are respectively equipped with intake grill and exhaust outlet; The interior intake grill of centrifugal blower is communicated with the intake grill of described shell, and the interior exhaust outlet of centrifugal blower is communicated with exhaust outlet on the described shell.
The pipeline fan shell generally adopts the cuboid shell, and intake grill and exhaust outlet are located at the two ends of rectangular structure, is convenient to being connected between pipeline fan and the pipeline; Adopt the shell of regular rectangular structure on the other hand, help the parallel arrangement of a plurality of pipeline fans, save the space.
Centrifugal blower comprises in spirality casing and the casing that by motor-driven impeller, the casing bottom surface is provided with interior intake grill, and interior intake grill edge is bent upwards and extends to form slip ring.The spirality fan casing makes the direction of the air-flow after impeller quickens consistent with interior exhaust outlet direction, more helps reducing turbulent flow, effectively reduces the noise that produces in the process of air delivery.Slip ring is general selects directly that compacting forms, the favourable further acceleration air-flow velocity of the employing of slip ring and reduce turbulent flow.
Motor is fixed on the outer wall of shell, makes blower fan use the conveying with high temperature gas flow, avoids the damage of high temperature gas flow to motor, helps prolonging electrical machinery life.Maintenance for the ease of blower fan is provided with access door at outer casing top surface, and being provided with highly and size of access door can be determined according to actual needs.
The beneficial effects of the utility model are embodied in:
(1) the rectangular structure flow blower casing helps the installation carrying of centrifugal pipeline blower fan, makes installation more firm, guarantees traveling comfort, reduces the mechanical shock noise, enlarges application area;
(2) centrifugal blower adopts the spirality flow blower casing, makes the direction of the air-flow after impeller quickens consistent with interior exhaust outlet direction, more helps reducing turbulent flow, effectively reduces the noise that produces in the process of air delivery;
(3) electric machine external structural design guarantees that pipeline fan can adapt to higher gas flow temperature, and Applicable scope is wider, is convenient to the installation and maintenance of motor simultaneously.
