🔍 Key Concepts

• Purpose of a fuel oil centrifuge in protecting engine components such as injectors and bearings • How improper assembly (e.g., bowl parts, sealing surfaces, or disc stack) could let contaminants or water pass through at high speed • The potential for mechanical failure at high RPM leading to damage to machinery and danger to personnel

💭 Think About

• From the cross‑section, think about what happens to unseparated solids and water if the disc stack or sealing rings are not correctly seated—where do those contaminants go next in the fuel system? • Consider what a bowl or cover failure at several thousand RPM would do inside an enclosed engine room space—who or what would be in the line of fire? • Ask yourself whether the effects of poor separation and possible bowl damage would be limited to just one engine component, or could reasonably affect several areas at once.

✅ Before You Answer

• Verify how dirty fuel can affect fuel injection equipment and main bearings over time • Check whether a high‑speed rotating assembly like the one in the illustration can cause projectile or bursting hazards if assembled incorrectly • Before choosing, decide if only one, two, or all listed consequences are realistic outcomes of running this type of centrifuge improperly assembled.
