The single stage compressor trainer is an educational unit designed to investigate isothermal and volumetric efficiency of single stage single acting reciprocating compressor at constant or variable speed operation. The compressor is driven by an electric motor through a v-belt when combined with drive & brake unit, and is connected to two tanks; an intake tank and a delivery tank.

                                     
  • A single stage single acting reciprocating compressor driven by an electric motor through v-belt when combined with the main drive and brake system.
  • The motors torque, rotational speeds of motor and compressor, compressor inlet and outlet temperatures, suction and delivery pressures and flow rate are measured via various sensors.
  • The training system is equipped with software system o which all experimentation, data logging and presentation are performed.
  • A data-acquisition system conditions and transfers the measured signals to the digital displays or the touch screen computer.
  • Both the motor and compressor rotational speeds are monitored via sensors to evaluate compressor efficiency which is a ratio of useful power to input power from the motor.
  • The slipping that takes place in the v-belt transmission system is accounted for by the control software.
  • The compressor is connected to a suction tank fitted with suction filters to help stabilize the flow to the compressor.
  • The compressor is connected to a delivery tank fitted with a solenoid valve that is to be operated via a switch on the control panel to discharge the tank.
  • The delivery tank is also fitted with an output throttling valve that may be used for stabilizing the delivery pressure in the tank.
  • The compressor’s suction line is fitted with venturi flow meter to measure the actual compressor flow rate.
  • Steady state condition can be achieved releasing compressed air through blow off valve.
  • The blow off valve is supplied with a silencer in order to diffuse the released air through a larger surface area which reduces turbulence and thus decreases noise levels.
  • Volumetric flowrate at the intake vessel can be determined through a provided nozzle installed within the system.
  • Safety precautions are implemented in this system by a set of pressure switches and safety valves to ensure safe operation of the system and safety of the users.
  • All of the system readings can be displayed and analyzed on a software system that is supplied with the training system.
  • The software system can be operated on an external PC that is connected to the system through USB port.
