🔍 Key Concepts

• Dynamic balancing of rotating machinery like pump impellers • Risks of drilling, welding, or chemically attacking an impeller • Proper machining practices to correct imbalance

💭 Think About

• Which methods could introduce new cracks, stress concentrations, or distortion into the impeller? • Which choice describes a controlled, accurate way to remove a known amount of material while keeping the impeller true and concentric? • How would each method affect the impeller’s strength and long‑term reliability under high-speed rotation?

✅ Before You Answer

• Compare which options use controlled machining versus rough or uneven material removal • Consider the dangers of heat input (welding) and random hole drilling on a high-speed rotating component • Ask which method is most likely to preserve the impeller’s structural integrity and balance while correcting the heavy side
