CAT NO: DIDACTICNLE-Export-191003
Centrifugal Compressor Test Rig.
Centrifugal Compressor Test Rig
The test rig consists of a centrifugal blower driven by a variable
speed electric motor. A motor controller is used to regulate the blower
speed. Ducts are fitted to inlet & outlet of the blower. A damper in
inlet duct is provided to regulate the intake air flow of the blower. A
Pitot tube with differential manometer is used to measure the air flow
rate. Two manometers are provided to measure intake & discharge
pressure of air. Two temperature sensors are used to measure the air
temperature at inlet & outlet. Blower speed & power consumption
are displayed using digital panel indicators.
Experimental Capabilities:
• To investigate performance of Centrifugal Compressor.
• To study effect of blower speed on delivery pressure, air flow rate.
• To study blower characteristics as function of speed, air flow rate & delivery pressure.
• To determine mechanical efficiency of centrifugal compressor.
