Specifications
 

Features

• Excellent pneumatic performance    

Semi-closed and mixed-flow type 3D impellers adopted, air flow out obliquely and gently to prevent air vortex for less flow loss.

• Energy efficiency Adjusted by inlet vane, plain blower unit efficiency curve. High energy efficiency achieved even under non-designed operation.

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 reasonable 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
