What is the typical allowable thrust clearance end play on an auxiliary turbine?

• A. .005 to .010 inch
• B. .008 to .012 inch
• C. .010 to .015 inch
• D. .015 to .020 inch

Answer: (C)

In the context of auxiliary turbines, thrust clearance or end play is critical for the proper functioning of the system. The typical allowable thrust clearance end play for an auxiliary turbine is established to ensure that there is sufficient space for thermal expansion of parts while still maintaining effective contact to transmit forces and power. The correct range, which in this case is .010 to .015 inch, allows for optimal performance of the turbine, ensuring that components do not excessively rub against each other or become misaligned due to thermal or operational fluctuations. This range provides a balance between too tight, which can cause binding and excessive wear, and too loose, which can lead to excessive vibrations and inefficiency in operations. Understanding this specification is essential for ensuring that the machinery operates smoothly and efficiently, thus preventing mechanical failures and extending the lifespan of the equipment.
