Compressor Operation, Maintenance and Troubleshooting Course
Introduction:
The course provides a comprehensive overview of the general technology and design principles of pumps and compressors. It encompasses the working principles of these machines, including their process and mechanical aspects, as well as considerations related to wear, lubrication, and troubleshooting. Participants will learn how to analyze vibrations and utilize other techniques for fault detection and diagnosis.
Course Objectives:
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
Who Should Attend?
This course is intended for engineers, supervisory and technical staff involved in the maintenance and inspection of pumps, compressors and plant engineers in the oil, chemical and other process industries who require a wider and deeper appreciation of pumps and compressors design, including their design, performance and operation. No prior knowledge of the topic is required.
