I. Development
content & scope & requirement:
|
1.
|
Based on the
existing lectotype software program, the data in the database is
input. The data in the database includes the existing fan weight
(rolling and sliding), starting torque (Actuator selection) and
original no dimension point. Additionally, the function of bidding
part for fan selection (including lectotype quotation list and
successful bid scheme, etc.) is enlarged and perfected.
|
|
2.
|
Integrate the
pneumatic calculation and structure strength from similar design
and variation design including critical speed calculation of the
rotor, impeller strength, rigidity calculation, rigidity
calculation of casing, startup time, GD2 calculation and finite
element analysis, etc.
|
|
3.
|
Second
development of the connection between the fan and solid-work, and
establish the 3D model parameterization for fan
components.
|
|
4.
|
The commercial
software (CFD) from fluent Company is used to simulate the internal
flow field of the fan and establish the value test platform of the
fan as well as realize the value and visualization of test. The
verification of static-blade adjustable axial fan model including
effect and replacement of every component and model performance
determination and expansion was finished in 2006. The geometric
parameter of the dynamic blade and the static blade were defined as
well. At the same time, the analysis and optimization of blower
performance has been completed. For existing model machine in the
factory at present, CFD flow field analysis was performed to
determine the correctness of original model of the machine and
modification opinion.
