  • Page 19: Factors Influencing The Separation Result

    3 Separator Basics 3.1 Basic principles of separation 3.1.1 Factors influencing the separation result Separating temperature For some types of process liquids (e.g. mineral oils) a high separating temperature will normally increase the separation capacity. The temperature influences oil viscosity and density and should be kept constant throughout the separation.
  • Page 20 3.1 Basic principles of separation 3 Separator Basics Phase proportions An increased quantity of water in an oil will influence the separating result through the optimum transporting capacity of the disc stack. An increased water content in the oil can be compensated by reducing the throughput in order to restore the optimum separating efficiency.
  • Page 21 3 Separator Basics 3.1 Basic principles of separation Disc stack A neglected disc stack containing deformed discs or discs coated with deposits will impair the separating result. Gravity disc The position of the interface is adjusted by altering the outlet diameter of the heavy liquid phase, that is by exchanging the gravity disc.

  • Page 22: Overview

    3.2 Overview 3 Separator Basics Overview The separator comprises a processing part and a driving part. It is driven by an electric motor. Mechanically, the separator machine frame is composed of a bottom part and a collecting cover. The motor is flanged to the frame. The frame feet have vibration damping.

    3 Separator Basics 3.3 Separating function Separating function Unseparated process liquid is fed into the bowl through the inlet pipe and is pumped via the distributor towards the periphery of the bowl. When the process liquid reaches holes of the distributor, it will rise through the channels formed by the disc stack where it is evenly distributed.

  • Page 25: Purifier Bowl

    3 Separator Basics 3.3 Separating function This bowl has two liquid outlets. The process liquid flows through the centre and out under the distributor. The liquid flows up and is divided among the interspaces between the bowl discs, where the liquid phases are separated from each other by action of the centrifugal force.

  • Page 26: Liquid Seal

    3.3 Separating function 3 Separator Basics 3.3.3 Liquid seal In a purifier bowl the liquid seal prevents the light liquid phase from passing the outer edge of the top disc, thus eliminating flow out through the outer path. The bowl must therefore be filled with sealing liquid before the process liquid is admitted.
  • Page 27 3 Separator Basics 3.3 Separating function The gravity disc is located inside the bowl hood. A gravity disc with a larger hole will move the interface towards the bowl periphery, whereas a disc with a smaller hole will place it closer to the bowl centre.
