Level : Proficiency

Course Content

  • E-learning: HYDRODYNAMICS BASICS

    Module 1: BASICS IN FLUID FLOW

      • Pipe system:
      • Liquid flows in pipes: friction losses.

  • Module 2: BASICS IN CENTRIFUGAL PUMP TECHNOLOGY

      • Centrifugal pump construction, main components.
      • Internal forces and mechanical criteria: balancing, wear ring clearances.
  • CLASSROOM TRAINING

    HYDRODYNAMICS APPLIED TO A PUMPING SYSTEM

      • Pump performance:
      • Flow in a pump, velocities triangle, internal flow and energy losses.
      • Theoretical and practical head: characteristic curve.
      • Other characteristics: efficiency, power, NPSH required.
      • Changes in characteristics vs. rotation, viscosity, impeller shape, cavitation.
      • Pipe system:
      • System curve, resistance of flow and throttling control.
      • Operating point: normal and maximum capacities, change in fluid characteristics and incidence on operating conditions.
      • Exercises with a dynamic simulator.

  • CENTRIFUGAL PUMP TECHNOLOGY & SELECTION

      • Centrifugal pump:
      • Impeller and pump shape, suction operating conditions.
      • Mechanical seal:
      • Selection according to API 682 standard and type.
      • Friction face heating.
      • Safety and environment: typical arrangements (single, dual, dry seal).
      • Specific solutions: canned motor pump, magnetic drive pump.
      • Installation:
      • Suction and discharge pipe design.
      • NPSH available; base plate and grouting.
      • Ancillary lines and equipment.
      • Coupling and driven machines.
      • Safety and environment.

  • POSITIVE DISPLACEMENT PUMP TECHNOLOGY & PERFORMANCE

      • Technology: different types of pumps (rotary and reciprocating pumps). Operation and performance of the different types of pumps.
      • Influence of clearance, internal leaks, nature of product on flow rate and pressure. Flow rate control.
      • Installation guidelines: position of tanks, line diameters, metering drums, pulsation dampeners, pressure valves.

  • PUMP OPERATION

      • Preparation: filling and draining. Start-up/shutdown: priming, hammer shock, risks to the process and the pump.
      • Monitoring parameters (vibration levels, noises, bearing housing temperature, motor intensity, pressures).
      • Parallel and serial operation. Safety conditions.
      • Reliability: types and source of failures (wear, ruptures, cavitation, leakages); improvement methods.
      • Exercises with dynamic simulator.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • describe the behavior and the operation of pumps,
  • participate actively in troubleshooting analysis and help to diagnose failures,
  • identify main parameters in pump selection.

Ways & Means

  • Actual examples from the refining, petrochemical and chemical industry.
  • Active participation is encouraged through case studies.
  • Use of a centrifugal pump dynamic simulator.
  • E-learning session previously to the presential one.
