This equipment comprises of a FD Centrifugal Blower coupled to a Motor. Three interchangeable impellers with forward, backward and radial vanes are provided with the test rig. A Pitot Tube is provided in the delivery line of blower for static and dynamic pressure measurement.

For (Variable Speed)

• Power input to the DC Motor is varied by means of a Thyristor controlled DC Drive to vary the RPM of motor. A RPM Indicator with Proximity sensor indicates the RPM of Blower.

For (Fixed Speed):

• AC motor is provided with MCB for overload protection.

Experimentation:

• To study the effect of forward curved, back curved and radial curved impeller
• To find out the discharge, head and efficiency of the Centrifugal Blower.
• To plot the graph Efficiency Vs Discharge
• To plot the graph Discharge Vs Head

Technical Details:

• FOR (Variable Speed): DC motor with Thyristor controlled DC
• Drive for variable speed
• FOR (Fixed Speed): AC motor, 1 HP Crompton make

Single Stage Air Compressor Test Rig consists of a single stage reciprocating type air compressor driven by 1 HP motor through a belt. The outlet of the air compressor isconnected to reservoir (Tank) and suction is connected to another air tank with an orifice plate and a water manometer. Bellow is fitted on one side of this air tank to regulate the flow. Temperature of inlet and outlet of air and pressure at outlet can be measured by Temperature sensor and pressure gauge.

Experimentation:

• To calculate the volumetric efficiency.
• To calculate isothermal HP.
• To calculate compression ratio

• Tachometer to measure RPM

Technical Details:

• Compressor: Single Stage, Capacity 4 CFM (max.)
• Manifold Tank: Suitable Capacity
• Flow Measurement: Orificemeter with Manometer
• Temp. Measurement: RTD PT-100 type sensor (2 Nos.)
• Pressure Gauge: Bourdon Type
• Energy measurement: Electronic Energy meter, L&T make.
• MCB: For overload protection.
• Instruction Manual: An ENGLISH instruction manual will be
• The whole set-up is well designed and arranged in a good quality painted structure.

Two Stage Air Compressor Test Rig consists of a double stage reciprocating type air compressor driven by 2 HP Motor through a belt. The outlet of the air compressor is connected to reservoir (Tank) and suction is connected to another air tank with a calibrated orifice plate and a water manometer. Bellow is fitted on one side of the air tank to regulate the flow. Temperature of inlet air, after single compression, inlet and outlet of second compression and pressure in reservoir and at intermediate stage can bemeasured by Temp. Sensors and gauges.

Experimentation:

• To calculate the volumetric efficiency.
• To calculate isothermal Horse Power.
• To calculate compression ratio.

Additional Information:

• Item Code: SHD-55
• Production Capacity: 100 units/month
• Delivery Time: 10-15days
