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, 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.
  • The unit includes a large control panel that features operation switches, digital displays.
  • The control panel includes trainer's on/off switch, electric motor on/off switch, delivery tank drain solenoid valve switch, electric motor speed control knob and emergency switch, also a schematic diagram of the 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.
  • A data-acquisition system conditions and transfers the measured signals to the digital displays.
  • 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 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 flow meter to measure the actual compressor flow rate.
