Y6-30 Boiler Fan

Patent No.:

★ Overview

    China now more varieties of boilers burning coal are quite different , and because of the installation of dust removal equipment and waste heat utilization equipment resulting from pumping force is insufficient , thus affecting the normal operation. In order to overcome due to the above causes pumping enough in the boiler combustion chamber pressure and other effects , and normal operation of the phenomenon , special design and manufacture of its wind, air pressure and boiler operating conditions match Y6-30-12 -type high efficiency centrifugal Boiler fan, for users to select applications .

★ Type

    1 ) . Direction of rotation of the fan can be made of two types of left and right .

    2 ) . The fan outlet angle can be made 0 °, 45 °, 90 °, 135 °, 180 °, 225 °, 270 ° seven kinds of patterns.

    3 ) . The fan drive is C type .

★ Structure

    1 ) . Blower mainly by the impeller, casing, air inlet , gear, damper components.

    2 ) . Impeller blades, front disc , rear disc and shaft plate , whose aerodynamic good performance , high efficiency , low noise , smooth operation, and by the sophisticated balancing check.

    3 ) . Chassis system made of high quality steel welded scroll .

    4 ) Transmission device consists of spindle bearing housing , pulleys and other components , spindle made of high quality steel refined, Rolling bearings .

    5 ) . Damper is used to adjust the size of the device fan flow , so that the wind, air pressure adjusted to the boiler running at its best.

★ Selection and Application

    1 ) . Fan performance

  Fan performance to the fan flow , total pressure , spindle speed , shaft power and efficiency parameter indicates ( see fan performance table ) , the performance parameters are given in the table according to the temperature t = 200 ℃, atmospheric pressure P = 101300Pa, smoke gas density ρ = 0.745kg/m3 calculated . If the fan does not match the above conditions of use , its performance should be translated at the actual working conditions .

    2 ) of fan selection

    ( 1 ) The fan connection with boiler supporting design, so you can just press the performance table selection , but the boiler output is subject to change by the transformation should be based on actual soot volume and resistance to re- press performance table for selection .

    ( 2 ) In the alternative use , should be translated according to the media after the selection criteria .
