About the course

Various types of compressors are found on an industrial plant; centrifugal, reciprocating, screw and axial compressors. This instructor led training course shows the participants each of these types of compressor, explaining to them the key components, how the compressor works, maintenance, operation and troubleshooting.

The centrifugal compressor is the subject of the first courses, and topics such as removing the casing, types of impellers, balancing, and wet and dry sealing are covered. Reciprocating compressors are then explained, with valve maintenance, clearance pockets and cylinder clearance being among the topics. Screw compressors, both dry and flooded, are then explained. The component and performance of axial compressors are subsequently detailed together with anti-surge control. Maintenance is a key focus in the explanation of all the compressors.

Performance monitoring and troubleshooting for all these types of compressors are explained. Signal processing and frequency analysis are introduced, and it is shown how measurements can be used to troubleshoot for misalignment, unbalance and clearance problems.

The course is formed of 10 modules split across 20 training hours. All modules will be live sessions with the instructor. This training course is available as a company in-house training only; there is a choice between an online training or an onsite training. All training materials will be available through your EngineeringTrainer account.
