Applications

a. For Cement industry: cement conveying blower,ventilating, etc.
b. For Sewage Treatment System: aeration blower, back-washing blower, etc.
c. For Pneumatic Conveying: to conveying powder materials, such as flour, cement, sand, grain, etc.

e. For Electric Power Plant: gas conveying, oxygen increasing, ventilating, dust cleaning, etc.


Key Technology

1. Inlet guide vane device

  • position——in front of blower impeller
  • Function——Not only for adjusting the blower capacity within 45% - 100%, but also for ensuring the blower to reach the highest efficiency within its adjusting scope, especially when operation parameters deviating from the designed data (low temperature or low pressure).
  • Adjusting——automatic or manual operation by clicking the touch screen on blower control box. Under the automatic operation, the inlet guide vane is adjusted by electric operator at a set ratio after it receives 4-20mA DC signal, while under manual operation or maintenance condition, the vane is adjusted manually.

2. Mature volute design

Reliable pneumatic performance, high efficiency, multi-variable efficiency of 85 %.

3. Impeller of high efficiency

  • The curve for the impeller is selected recurring to simulate working condition on computer, and better fitting for the actual flowage of gas.
  • Made of aerial aluminum alloy or stainless steel, open path backward bent (its smallest dip angle of 6 degree), surface fine machined.

4. Step-up gear box structure and bearing of high reliability

  • The gear box is of horizontal –split structure, volute casing connected to lower casing and separated from upper casing,through which shorten the time required for unloading box cover.

  • High-speed shaft adopts hard thrust disc technology, high-efficiency and low mechanical loss confirmed by line contact.
  • Ellipse ( dislocation ) bearing adopted for big gear,tilting-pad bearing for high-speed gear.
  • The shaft of blower and gear is made of heat-treated forging steel and proper grinded. Every horizontal critical speed is within the scope of±15% than the normal speed, and torsion resonance speed is within the scope of±10% than the running speed, all rotating parts is dynamic balanced.
  • The step-up gear is of Parallel Axis helical type with integral small gear and rotating shaft.

  • Made of surface-quenching forging alloy steel and precisely grinded, the gear’s service index is 1.8 at least.

5. High-precision gear driving

  • Gear of the higher quality grade adopted
  • Gear precision grade is stabilized at ISO1328 5~4
  • The precision grade can reach 3.
  • Precision grade equal to the standard AGMA or DIN

6. Connection between impeller and high-speed shaft

  • Adopt the connection type of straight end-face key (pin) and triangular shaft
  • The highest power it transferred reaches 3,000 kW.
  • Convenient in assembling and disassembling without damage to parts

7. Seals of high performance

  • The material of seals is alloy of soft texture. (spiral seal adopted)
  • Reliable function, long service life
  • No leakage problem
  • Low cost required for maintenance, convenient in replacement
  • Energy consumption lowered by no friction



Operation result

  • The most Striking feature of GS blower is energy efficiency.

From Mar. 1, 2009, we have started trial running of one blower (Model: GS160) in Qiting Sewage Treatment Plant.

Comparing with two roots blowers each of capacity 80m3/min and motor power 132kW operated before, every month 30000 RMB has been saved after use of GS Single-stage High-speed Centrifugal Blower, though it is not at full load operation.

  • Safer and More Convenient

Controlled full-automatically with every breakdown recorded, more convenient for operator

  • Low noise
