Pumps & Compressors: Predictive Maintenance & Diagnostics

Pumps & Compressors: Predictive Maintenance & Diagnostics

OBJECTIVES

The program assumes familiarity with the design and construction of pumps and compressors. From this starting point it adopts an analytical approach to understanding the failure of all types of pumps and compressors.

From a component-by-component perspective, the program 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 program 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.
