Description

“Zero Leakage” Inlet Guide Vanes

• Adjustable inlet guide vanes provide optimum flow patterns as well as precise and continuous control across the machine’s full operational spectrum
• Self-energizing back plate maintains zero sidewall clearance for maximum expander efficiency
• Zero backlash variable guide vane configuration provides smooth turn-up capability to 125% of design flow

Rugged Rotor Design

• Stiff rotor shaft and high capacity tilt pad bearings assure maximum stability at all operating loads and speeds
• Sealing design offers robust construction and reliable performance
• Uniformly loaded drive tangs provide the high torque capacity necessary to handle upset conditions

Self-Aligning Wheel Attachment

• Tapered bore and stretch rod design automatically compensates for thermal and mechanical changes to maintain alignment under all operating conditions
• Precision machined tapered bore/shaft attachment allows independent balancing of turbine wheel and shaft to facilitate field repair
