It also contains step- by-step instructions for dismantling and assembly of the separator for service and repair. Fault Finding Refer to this chapter if the separator functions abnormally.

  • Page 18: Design And Function

    2 Read this first & Separator Basics 2.2 Design and function 2.2.1 Application The P 615 is a high-speed centrifugal separator intended for marine and land applications. It is specifically designed for cleaning of mineral oils from water and solid particles (sludge). The cleaned oil is discharged continuously, while the sludge is discharged at intervals.
  • Page 19 2 Read this first & Separator Basics 2.2 Design and function 2.2.2 Design The P 615 separator comprises a frame consisting of the frame lower part, the intermediate part and the frame top part with a frame hood. The separator bowl (C) is driven by an electric motor (A) via a flat-belt power transmission (D) and bowl spindle (B).
  • Page 20 2.2 Design and function 2 Read this first & Separator Basics 2.2.4 Separating function Liquid flow Separation takes place in the separator bowl to which unseparated oil is fed through the inlet pipe (201). The oil is led by the distributor (T) towards the periphery of the bowl.
  • Page 21 2 Read this first & Separator Basics 2.2 Design and function Water seal in purification To prevent the oil from passing the outer edge of the top disc (I) and escaping through the water outlet (221), a water seal must be provided in the bowl.
  • Page 22 2.2 Design and function 2 Read this first & Separator Basics Clarifier disc In the clarification mode, the gravity disc is replaced by a clarifier disc which seals off the water outlet. In this case no water seal is required and consequently there is no oil/water interface in the bowl.
  • Page 23 2 Read this first & Separator Basics 2.2 Design and function Bowl opening The key event to start a sludge discharge is the downward movement of the operating slide. This is accomplished by supply of opening water (372) to the discharge mechanism. Water is drained off through nozzles (Y) in the bowl body.
  • Page 24 2.2 Design and function 2 Read this first & Separator Basics 2.2.6 Power transmission Bowl spindle In addition to its primary role in the power transmission system, the bowl spindle also serves as: • pump for the closing water • supply pipe for the closing water •...

  • Page 38 Disintegration hazard Inspect regularly for erosion damage. Inspect frequently if the process liquid is erosive. Always contact your Alfa Laval representative if the largest depth of any erosion damage exceeds 1,0 mm. Valuable information as to the nature of the damage can be recorded using photographs, plaster impressions or hammered-in lead.
  • Page 39 Always replace a part if cracks are present It is particularly important to inspect for cracks in rotating parts. Always contact your Alfa Laval representative if you suspect that the largest depth of the damage exceeds 1,0 mm. Do not continue to use the separator until it has been inspected and cleared for operation by Alfa Laval.
  • Page 40 3.3 Check points at Intermediate Service 3 Service Instructions 3.3.4 Discharge mechanism Dirt and lime deposits in the sludge discharge mechanism can cause discharge malfunction or no discharge. • Thoroughly clean and inspect the parts.

  • Page 41 3 Service Instructions 3.3 Check points at Intermediate Service 3.3.5 Bowl hood and sliding bowl bottom Poor sealing between the bowl hood seal ring and the edge of the sliding bowl bottom will cause a leakage of process liquid from the bowl. A Sealing surface in the bowl between bowl hood and sliding bowl bottom.
  • Page 42 3.3 Check points at Intermediate Service 3 Service Instructions Check the sealing edge (a) of the sliding bowl bottom. If damaged through corrosion or erosion or in other ways it can be rectified by turning in a lathe. Minimum permissible height of sealing edge: 4,5 mm.
  • Page 43 3 Service Instructions 3.3 Check points at Intermediate Service 3.3.6 Spindle top cone and bowl body nave Impact marks on the spindle cone or in the bowl body nave may cause the separator to vibrate while running. Corrosion may cause the bowl to stick firmly to the spindle cone and cause difficulties during the next dismantling.
  • Page 44 The measure A in millimetres (mm) is obtained by calculating bowl outside diameter D times 0,2. If the marks are illegible, an Alfa Laval representative should be contacted for (MAX 25 ) determination and punching of new alignment marks.
  • Page 45 3 Service Instructions 3.3 Check points at Intermediate Service Damage Contact surfaces to inspect on the bowl The position of threads, contact and guide surfaces are indicated by arrows in the illustration.
