Q

The first step when resetting the slide valves on a duplex reciprocating pump is to __________.

🔍 Key Concepts

• Function of slide valves in a duplex reciprocating pump steam end • Relationship between steam piston position and valve setting • Why initial mechanical position matters before any measurements or adjustments

💭 Think About

• Think about what physical position of the moving parts makes it easiest and most accurate to set the slide valves evenly. • Ask yourself: before you can measure or compare port openings, what condition must the pistons and valves be in? • Consider which piston position would place the valve gear in the most neutral, central, or balanced condition for adjustment.

✅ Before You Answer

• Identify which step is truly the starting condition before any measuring or fine adjustment is done. • Check which options describe a specific piston stroke position versus a later verification/measurement step. • Verify which choice would logically let you set both directions of travel (forward and return stroke) symmetrically.
