  • WEEK 2: HANDS-ON ACTIVITIES IN WORKSHOP

      • Hands-on activities in our workshops with our tools and metrology instruments:
      • Work on motor/pump block (asynchronous motor/overhung centrifugal pump) and work on double shaft centrifugal pump.
      • Receipt of a pump from the plant or the site(*).
      • Use of the technical file, maintenance routings and understanding of anything related to the schemes and information files: dimensions, adjustments, tolerances, functional clearance
      • Identification of the spare parts(*).
      • Presentation of the tools in a metrology workshop, performances and rules of use.
      • Compliance with disassembling/assembling procedures.
      • Geometrical inspection of the piece of equipment.
      • Inspection of the condition of the elements and the wearing parts at disassembly: corrosion, defects, coupling, wear, rupture.
      • Inspection of clearances at disassembly.
      • Functioning and use of support equipment: bearing heating by induction, monochromatic light for mechanical seal inspection(*)
      • Tests after repair and compliance with good practices.
      • Preparation of an intervention report.
      • For in-house courses, the above-described hands-on activities can be carried out in your workshops and on-site, on a piece of equipment to be repaired or overhauled, with your tools and metrological instruments.
      • (*): indicates activities that can only be performed in the case of an in-house course in your workshop.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • know the basics of technical drawing, characterize a part, a mechanical assembly,
  • master the rules of the art of mechanical system design, identify the main assemblies such as bearing assemblies,
  • know the main elements of power transmission (gears, gimbals…),
  • wisely use the metrology instruments used in the workshop (use, performances, calibration),
  • carry out a disassembly and assembly routing of a centrifugal pump – and more generally of a machine – by completing the dimensional and geometrical inspection required.

Ways & Means

  • Very interactive animation by highly experienced trainers.
  • Stepwise approach, from the dimensioning of a simple part to the assembly in the workshop.
