INTRODUCTION

This course covers both the theories and practical applications of pumps and cooling towers in buildings. The course leader will assist the participants to understand the fundamental theories of water pumps, highlighting the important requirements for proper installations. In the application of the water pumps, different system configurations will be introduced. Emphasis will also be made in the area of energy saving regarding the design and operation of the pumps. This course will also cover the service maintenance of water pumps.

Objective

  • Describe the operation of a basic cooling water sys­tem.
  • Describe what occurs in the tower during the cooling process.
  • Describe the operation of various types of cooling
  • Explain how cooling occurs in a cooling tower
  • Describes the general design and operation of nat­ural-draft and mechanical-draft cooling towers: in­duced-draft towers and forced draft towers.
  • Describe the functions of the auxiliary componentsused with cooling towers.
  • Understand typical cooling towers maintenance re­quirements
  • Describe general procedures for shutting down and starting up cooling tower.
  • Describe the maintenance regimens for cooling tow­ers
  • Perform troubleshooting techniques for cooling tow­ers.
  • Explain how problems caused by suspended and dis­solved solids can be minimized.
  • Explain what dissolved gases and micro-organisms are, how they affect cooling water systems, and how their effects can be minimized.
  • Describe ways chemicals are added to cooling water systems.
  • Describe precautions when working with hazardous chemicals

Who should attend?

  • Facilities and maintenance technicians, engineers and managers
  • Test, utilities, plant, process, control engineers and managers
