A motor driven multi-stage centrifugal compressor mounted on a stainless-steel plinth with transparent air inlet and air outlet ducts. A manually operated adjustable aperture allows the air flow rate to be varied at constant fan speed. A calibrated orifice plate is used on the discharge to measure the air flow rate.
Electronic sensors measure the pressure head developed across the blower, the pressure across the orifice plate (and hence the flow rate) and the air temperature.
The compressor speed is accurately controlled by an advanced electronic inverter. This inverter also calculates the torque produced at the motor drive shaft allowing the power used by the fan to be derived. The also provides the conditioning electronics for the sensors and allows their readings to be displayed on the computer software.
Multi-stage compressors are used industrially for high pressure deliveries of gas flows or suction duties.
The kinetic energy imparted to the gas by the impeller rotation is converted into pressure energy which progressively increases from stage to stage.
