The impeller stated is made of rear trochal disc, blade, core wheel and preceding wheel disc, and wherein rear trochal disc, blade and preceding wheel disc are using Q345E material
Material, can meet intensity and life requirements simultaneously.Impeller is meeting aeroperformance using 24 blades for forward centrifugal impeller
It is required that while but also the noise of blower has obtained effective control.Impeller is fixed by retaining ring and lock washer with left-hand bolt
In on motor-shaft extending end.
The spiral case is made of front side board, top plate, back side panel and the side of spiral case is provided with mounting rack, which is
L-type mounting rack, motor are placed at the lower end of mounting rack, and mounting rack is welded on spiral case back side panel, to guarantee blower bonding strength,
It is set on crossbeam and stiffening plate on mounting rack there are four mounting hole, is provided with two width resilient cushions, two width dampings on each mounting hole
Platform sling is provided between pad, which is mounted on motor-car with bolt by the screw hole on platform sling with traction blower
On group vehicle bottom, the suspension centre for lifting is respectively equipped on front side board and mounting rack, the spiral case of above-mentioned part composition is that entire blower mentions
Runner and support construction are supplied.
The motor is double independent winding blowers, and motor connects support by the motor mounting plate on spiral case, and passes through
Motor flange is fixed on spiral case back side panel.
Setting is improved the reinforcing rib of spiral case intensity on the mounting rack.
The utility model has the advantage of the centrifugal blower running environment is severe, therefore need to be equipped with sandstorm filter, but pacifies
It is limited to fill space, it is contemplated that integral layout, thus sandstorm filter and transition air duct is separately installed, pass through vehicle with fan main body
The air duct at bottom connects, and has not only been able to satisfy performance noise requirements, but also confirmation installation does not have interference.Independent filter is connected by transition air duct
It connects and is installed at vehicle bottom, meet customer requirement.Blower and 4 tie points of car body are not in same level, therefore blower fan structure mostly uses
High-strength aluminum alloy bending and molding, both guaranteed it is taken up space small, it is light-weight, but guarantee blower intensity.
