    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 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 (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 highest quality grade adopted
    • Gear precision grade is stabilized at ISO1328 5~4
    • The highest 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 can be 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
