Students are to acquire necessary knowledge to trouble-shoot the machinery, reveal main cause of malfunction and prescribe remedial action. Introduction of equipment and devices for engineering diagnosis and skills development for applying them.

In this course students prepare to accumulate engineering knowledge and skill to approach an object, use the technical documentation to understand system operation, apply appropriate methods of check out, collect relevant data, compare the the results with ISO proposed norms, make a decision and specify the list of remedial action.

Lectures: Description of common objects of diagnosis. Typical machinery composition. Subassemblies. Machinery outlines. Different diagnostic models, monitoring priorities and optimization. Diagnosis of: distributing networks for propelants, compressed air, gases, steam, lubricants, etc. Site measurements. Description and classification of different kind of measurements. Diagnostic algorithms and machinery structurizing. Selection of diagnostic parameters. Diagnostic devices. Functions and accessories. Schedule of inspection. Critical machine operating range. Preliminary measurements. Troubleshooting. Reporting. Overhaul and rehabilitaion program definition. ISO verification. Run out check up. NDT inspection. Lubricants inspection.

Exercises, Lab work: Typical machinery - generators, blowers, pumps, compressors, turbines, transportation lines. Site measurements: temperature, pressure, fluid flow, velocity, position, acceleration, displacement. Site diagnosis: troubleshooting, rehabilitation list. Geometry check out: shape, position and dimensional tolerances. NDT inspection: magnetic particles, chemical agents, ultrasound. Vibrodiagnosis: spectral analysis, peak detection, phase lag measurement. Technical liquids and gases analysis. Proactive strategy of maintenance.
