🔍 Key Concepts

• Identify in the illustration where the operating slide, seal ring, and sludge ports are located and how they move during sludge ejection. • Recall that bowl opening on a self-cleaning centrifuge is a hydraulically actuated movement, not a separation process function. • Think about which fault would prevent the bowl from physically moving to the open position, versus just reducing purification efficiency or partially restricting flow.

💭 Think About

• Which of the listed faults would stop hydraulic pressure from acting effectively on the sliding mechanism so the bowl never opens at all? • Which options mainly affect the quality of separation (inside the disk stack or ports) rather than the mechanical actuation of the bowl opening? • If operating water pressure were incorrect, would "too high" or "too low" more likely cause a failure to open? How does that help you eliminate one option?

✅ Before You Answer

• Be clear on what actually makes the bowl open in this type of centrifuge (look at the water chambers and sliding parts in the lower section). • Decide which component, if defective, would cause loss of operating water pressure at the slide rather than a simple blockage. • Eliminate any choices that would still allow the bowl to open mechanically but would only cause reduced sludge discharge or poor separation.
