Course Description
The course is a continuation of EN‑1222 Auxiliary Machinery I and covers the installation, operation, maintenance, and repair of operating machinery including steam traps, strainers, pumps, compressors, heat exchangers, vacuum pumps, air injectors, deaerators, hydraulic and pneumatic systems, and basic operating characteristics of combined-cycle operation. The lab consists of the breakdown and repair of operating pumps and compressors including the electrical demand parameters of the machinery both loaded and unloaded. The lab uses cutaway equipment and operational trainers and simulators to enhance the understanding of the material presented in the course. [Lab time required]
This course consists of three 1-hour classes a week for a semester, six 4-hour labs with practical assessments, and a comprehensive final exam.
