Computer Controlled Thermodynamic Cycle Of A Piston Compressor

Computer Controlled Thermodynamic Cycle of A Piston Compressor

Description

• A Computer Controlled Thermodynamic Cycle of a Piston Compressor training plant for studying the energy transfer in a compressed air system.
• The is controlled by a PC and software.
• It includes industrial sensors and transducers.
• The is designed to connect to the to expand the experimental capability.
• The has been designed and manufactured to incorporate all current safety standards

Experiments

• Analysing the pressure / volume diagram of the first and second stages of the compressor by experiment
• Determining the polytropic index
• Calculating the effective average pressure of the first and second stages of the compressor

Checking the operation of the safety devices

• Using a T-s diagram for air to determine the characteristics of the thermal cycles by experiment
• For detailed study of the air characteristics it is necessary to connect the to the Compressed Air Dehumidification Training Plant
