🔍 Key Concepts

• Flow path and location of line P at the bottom of the centrifuge bowl • How a self-cleaning purifier bowl opens and closes using operating water or control liquid • Difference between priming/filling the bowl and controlling the sludge discharge cycle

💭 Think About

• Look at where line P enters the machine and which space it connects to: does it go to the operating water chamber under the bowl or into the product space? • In the self-cleaning cycle, which step requires water pressure under the sliding bowl bottom: opening the discharge ports, or locking them closed again? • Would a line at the very bottom be the best choice for continuously positioning the oil/water interface, or is it more likely tied to intermittent control actions?

✅ Before You Answer

• Trace line P to see if it feeds the operating water / sliding bowl bottom area rather than the disc stack where oil and water separate • Recall that bowl opening uses a sudden change in water volume underneath the sliding bottom, while bowl closing requires a different water chamber to be filled and held • Confirm whether priming the bowl is normally done through the oil inlet at the top, not a low line like P
