Mechanical Maintenance Career Opportunities
The acquisition of a degree is an indication of a willingness to invest substantial time, money, and effort in the pursuit of academic preparation and training for career competence. Employers often consider that an individual who has made this commitment is not only better informed but is more likely to have the proven critical thinking and problem solving skills to assume greater responsibilities as time passes. This is evidenced by employer comments to the effect that while a degree may not insure position, individuals with degrees will nearly always realize more rapid responsibility and income growth in their organizations.

Mechanical Maintenance Engineering covers a broad spectrum of potential employment options. In addition to the options which are open to Heating, Ventilation, Air Conditioning and Refrigeration (HVAC/R) Technicians and Electricians, graduates of this program would be likely candidates for entry level into industrial and institutional maintenance engineering positions, industrial refrigeration service and other career paths which require maintenance and service of large, complex systems.
Educational Objective
The objective of this course is to provide training and education in adequate depth and breadth to allow graduates access to diverse and demanding career positions. Students are required to complete each phase with a proven degree of competence. Upon completion of the program and acquiring an Associate of Occupational Studies Degree in Mechanical Maintenance Engineering, students should have the necessary skills to fulfill this objective.
NOTE: First academic year is concluded upon successful completion of (24) semester credits and 30 weeks of training. Second academic year is concluded upon successful completion of (48) semester credits and 60 weeks of training.
Content & Philosophy
Graduates of this program will complete a
schedule of courses which effectively encompass all the requirements of the Electro-Mechanical Technologies Program and a subsequent series of phases with none being dependent upon the other. Therefore, the only prerequisite of any phase or course is the equivalent of the Electro-Mechanical Technologies Program. This allows maximum flexibility to students in scheduling the start of their studies.
Students in later phases of training will have an educational experience which is much more of an academic exercise than encountered in other programs at RSI. The intent is to build upon the foundation of previous training, which includes a great deal of hands-on activities, and more focus on academic exercise.
The coursework in this program is as outlined in the
Electro-Mechanical Technologies Program plus five (5) additional phases of
training. Each of these additional phases will encompass four (4) of the following topics in an order consistent with completion of prerequisites, and each will accrue six (6) semester credits.
Pneumatics:
This unit includes the study of typical pneumatic control systems: The evaluation, maintenance, operation and troubleshooting of the air station, controlled devices, controllers, receiver controllers, transmitters, relays and switches which make up a pneumatic control system. An introduction to air compressors which drive a pneumatic system is also discussed.
Preventing Compressor Failures:
This unit covers why and how compressors fail, how to detect the cause of compressor failures and how to prevent repeat compressor failures. Commercial serviceable hermetic reciprocating compressors are covered, as well as Rotary and Scroll compressor operation and servicing. Also covered are maintenance of reciprocating, rotary and centrifugal air compressors and compressed air systems. |
