🔍 Key Concepts

• High-speed rotating machinery safety checks before startup • Critical components of a centrifugal separator bowl assembly • Consequences of improper securing of major rotating parts

💭 Think About

• Which part, if not properly secured before startup, could cause the most severe mechanical damage or safety hazard when the unit reaches full speed? • Looking at the diagram, what key rotating component must be firmly attached to the drive/spindle for safe operation of this type of separator? • Among the choices, which item is most directly related to physically holding the main rotating bowl in place?

✅ Before You Answer

• Identify the main type of machine shown (centrifugal separator/oily water separator arrangement) • Determine which option concerns the primary rotating assembly itself, not just auxiliary systems like pumps or controls • Confirm which component, by manufacturer procedure, is always checked for correct tightness/securement before starting this kind of high-speed device
