PROGRAM DETAILS

Introduction

Compressors & pumps became widely adopted and many thousands of sets are now installed worldwide.  The development of pumps & compressors from the theoretical stage to its present worldwide adoption has three main inputs. These may include:

  • The practical and theoretical work of established on pumps & compressors.
  • Intensive and aerodynamic work on compressors. By aero-engine manufacturers, arising particularly from the development of aero engine superchargers
  • Metallurgical developments, which provided alloys capable of withstanding the continuous high temperatures and stress to which the pumps & compressors are subjected.

This course will provide an excellent opportunity to learn and understand the operations, the constructions, maintenance, the vibration problem troubleshooting and problem solving in all types of pumps & compressors. Moreover people are becoming increasingly aware on causes and how to diagnose faults and the reasons behind some pumps & compressors problems and how to solve them. 

Pumps and compressors are generally critical machines in any production process, and hence it is vital that maintenance is most effective for these units. Delegates will be provided with a comprehensive understanding of how to use a combined predictive and preventive maintenance approach to achieve maximum reliability and greatest understanding of any deterioration that may occur.

Learning Objectives

Upon completion of this short course, the participant will be able to understand the principle of compressors and compression technology and the principles of their operations.  They will appreciate the applications of compressors. They will be able to assess and measure vibration, calibrate vibration measurement systems.  They will also be able to understand how to manage and solve other problems related to pumps & compressors.

The course adopts an analytical approach to understanding the failure of all types of pumps and compressors.

From a component-by-component perspective, the course investigates the root causes of failure, and relates these to operating conditions and process parameters. Design, installation, lubrication and wear related failure mechanisms are identified and a detailed understanding of the troubleshooting and diagnostic methods needed to detect and identify these is developed.
The training course provides participants with the knowledge needed to be effective in the inspection, monitoring and diagnostics of pumps and compressors, with emphasis placed upon the importance of a combined condition monitoring and strip-down inspection approach to maintenance.

Who Should Attend?

  • Operators and engineers who are involved with pumps & compressors, operation and maintenance
  • Those who have engineering backgrounds and works on pumps & compressors.

It is also suitable for Engineers, supervisory and technical staff involved in the monitoring, predictive maintenance and diagnostics of pumps and compressors.

Training Methodology

The course is delivered in a combination of lecture style and group workshops. In addition, a significant amount of time is set aside for small working group activity when addressing case study problems. Extensive use is made of case study material to underline the key aspects of the course and to give the delegates exposure to current best practice.

The course will be taught in English (materials and notes will be in English).  It is up to British approach and standard.  The course will be theoretical teaching and calculations, covering case studies.
