What you will learn

  • Understand centrifugal pumps working principles for successful operation of your plant and piping systems
  • Understand centrifugal pumps construction details (impeller, volute, shaft, bearings, packing, mechanical seals, etc)
  • Lear how to read and interpret your pump curves
  • Learn how to determine and interpret your piping system curve
  • Optimize the operation efficiency of  your pumping systems
  • Analyze the problems in operation related to packing, mechanical seals, bearings and flow control
  • Apply the best practices and guidelines for maintenance, problem solving and troubleshooting

Description

Centrifugal pumps of various designs and applications are encountered nowadays throughout refining, petrochemical and process industries as well as in power generation and environmental engineering.

This course is designed to provide you with a complete understanding of the construction details and functioning of centrifugal pumps. This understanding is a prerequisite for the successful operation of the plant and piping system.

The course includes extensive graphics, 3D animations and cut sections to give you a virtual practical exposure on centrifugal pumps.

The objective of this course is threefold :

1. Break down for you all the centrifugal pump operating principles into easily digestible concepts like cavitation, performance curves, head, etc

2. Illustrate through 3D animations and cut-sections the main pump mechanical components like impellers, shafts, bearings, packing, mechanical seals, etc

3. Provide guidelines and best practices for operation, maintenance and troubleshooting

Pre-requisite:

Some engineering or field knowledge is preferable but not mandatory. All of the concepts are explained in depth using an easy to understand language to allow students to build their knowledge from the ground up.
