Reciprocating Gas Compressor Operations and Maintenance Course
Introduction:
Course Objectives:
This course is designed for engineers and supervisors involved in the operation and maintenance and troubleshooting of reciprocating compressors. The course provides an in-depth study of reciprocating compressors technology, performance, operation and maintenance. Participants will be able to solve operation and mechanical problems. Participants will practice a complete compressor overhauling and parts inspection at the workshop and report the compressor condition.
