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 can transfer 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
