🔍 Key Concepts

• Centrifuge bowl construction – notice whether the bowl itself moves or if an internal piston moves to open the sludge ports • Self‑cleaning vs solid bowl – look for sludge discharge ports and a water seal arrangement, which indicate automatic self‑cleaning • Pump vs purifier – compare the presence of a disc stack, sludge space, and outlet paring devices (purifier features) versus cylinder blocks and pistons (axial piston pump features)

💭 Think About

• Study the lower part of the bowl in the illustration: what component actually moves to open the sludge discharge ports – the outer bowl or an inner piston? • Look around the periphery of the bowl: do you see openings/ports and a sludge space that would let solids be discharged automatically, or does the design suggest a permanently closed (solid) bowl? • Compare the internal stack of conical discs and paring chambers at the top with what you would expect inside a hydraulic pump – which machine does this arrangement more closely resemble?

✅ Before You Answer

• Verify whether there are sludge discharge ports around the rim of the bowl – that would rule out a simple solid bowl design • Identify if the disc stack and paring chamber at the top match typical fuel oil purifier construction, helping you eliminate the axial piston pump option • Decide from the drawing whether the vertical motion during cleaning would be from a sliding piston inside the bowl or a sliding bowl shell itself, and match that to the remaining centrifuge choices
