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
