The port labeled "H" of the device shown in...

🔍 Key Concepts

• Self-cleaning centrifugal purifier bowl layout – where sludge exits versus where water enters/drains • Function of operating water: opening water, closing water, and any drains that keep the operating slide moving freely • Physical location of port H in relation to the operating slide (R) and the sludge space (O) in the cross‑section

💭 Think About

• Trace the flow path from the operating water inlets at the top (A, B, C) down to the bottom of the bowl – where would water need to be removed so it does NOT interfere with the movement of the operating slide? • Look at where actual sludge leaves the bowl during a dump – does it pass anywhere near port H, or does it leave through entirely different openings in the bowl periphery? • Ask yourself whether port H appears to supply water into a space, or to drain/relieve water from beneath the moving parts at the bottom of the bowl.

✅ Before You Answer

• Verify whether port H is connected to the sludge space (O) or to a small passage leading away from underneath the operating slide R. • Check if port H is drawn as a small drain passage rather than a large discharge opening for sludge. • Confirm which exam choice describes a function that matches a small drain under the operating slide versus a main operating-water inlet or sludge discharge.

The port labeled "H" of the device shown in the illustration, is used to __________. See illustration MO-0012.

prevent water from accumulating beneath the operating slide

provide water flow for closing the bowl at the end of the desludging cycle

bleed off the opening water to permit the closing sequence of the bowl at the end of the desludging cycle

directly discharge accumulated sludge from the bowl
