High-Efficiency and Low Noise Suspension Centrifugal Blower with
Foil Bearing Technology for Industrial Applications
Product Description
Foil Bearing High-speed Centrifugal Blowers is a
high-efh.ciency,energy-saving,green and environmentally
friendlyproduct, its mechanical structure is simple, the moving
partsare few, the control robustness is good, and the maintenanceis
convenient. It adopts automotive-grade oil-free andhigh-reliability
dynamic pressure foil bearing, which has nofriction and small
mechanical loss during operation. Usingadvanced permanent magnet
synchronous motortechnology, the maximum speed can reach 95000rpm,
and itonly takes 5s to run at full speed.The motor effciency is
ashigh as 97%, which meets the two-stage energy effciencystandard.
The high-effciency ternary flow impeller used in the FoilBearing
High-speed Centrifugal Blowers breaks through thekey technology of
low specifc speed design and has higheffciency. The integrated
special design of the main enginemakes the noise less than 75dB(A)
and the vibration less than12um. It adopts stepless adjustment, and
the blower can startand stop quickly, and the number of continuous
starts andstops exceeds 200,000 times.
Foll Bearing Technology
Foil bearing has physical contact between therotor and the bearing
before starting, therelative movement of the rotor and the
bearinggenerates air pressure when starting, when therotor rotates,
the speed of the air around therotor can be converted into pressure
energy, andthe air pressure makes the rotor float when therotor
reaches a certain rotation speed and playsa lubricatingrole. Foil
bearing technologyeffectively solves theproblems of lowefficiency,
short life, and the need forregularmaintenance and lubrication of
the traditiona!mechanical support transmission system.

When the atmospheric conditions and medium are varied,the relative
performance conversion calculation will
be different,we can re-designed in accordance wth the requirement
of users to adape to different working condi
tion. There are two cooling methods for air suspension centrifugal
blower: self-circulating water cooling and forced
air cooling. If you have special requirements on the cooling mode,
please tell us in advance.

High Performance Aerodynamic Design Methodology for Wide Service
Conditions
By studying the influence of impeller and volute flow on efficiency
and working stability, the R&D team proposed a flow control
method and a pneumatic optimization design method to improve the
performance of the main engine, which greatly improved the
efficiency of the main engine.
Manufacturing & Equipment Base
has built laboratories, R& D buildings, processing workshops, etc.,
with internationally advanced and China leading high-precision
processing equipment.
High power density permanent magnet synchronous motor technology
Based on the thermal multiphysics coupling design technology of
electro magneticmachine, the R&D team independently developed a
permanent magnet synchronous motor (PMSM); Through the
electromagnetic optimization design technology of high speed
permanent magnet motor coordinated with the control strategy, the
problems of large rotor heat, high torque ripple and large motor
noise are solved, so that it has the advantages of high
reliability, high temperature resistance and low wind resistance
loss. The design and process of rotor structural integrity were
overcome, and a permanent
magnet synchronous motor with high power density, low cost and high
efficiency was developed.
