Mechanical EngineeringQ&A LibraryYour task in the maintenance department, for a compressed air systems company, is to investigate any faults or modifications and critically evaluate parameters that would affect the volumetric efficiency of reciprocating compressor. Figure.4 shows compressed air system diagram used to deliver a high pressure for a laser cutter and a pneumatic robotic arm in fabrication lab for innovative projects. In this diagram, component (1) is the source pressure container (at ambient conditions), component (2) is the compressor and line (3) is the delivering high pressure line. The required delivered pressure must be 8 bars and due to leakage in the delivering high pressure line, the technician compressed the air up to 10 bars to compensate for this leakage. After carrying out the required maintenance procedures and fixing the leakage issue, it was found that compressor consumes less power and exhibits higher volumetric efficiency. Additionally, you have suggested to insulate the compressor as a design modification to increase the stroke and bore specifications of the compressor to obtain better performance in terms of volumetric efficiency Figure.4: Diagram of compressed air system Show that the volumetric efficiency of ideal reciprocating compressor is given by: Nvot = 1-c Based on the observations and discussion in the introduction of this task, critically evaluate parameters that would affect the volumetric efficiency of reciprocating compressor. Make use of the above formula to thermodynamically and mathematically interpret its parameters effect on these observations and the discussion presented previously.Start your trial now!
