Description
This specialized closed-circuit laboratory apparatus is designed to evaluate the operational behavior and performance characteristics of a centrifugal pump. It consists of the following key visible elements:
- Centrifugal Pump: The dark blue electric motor-driven pump assembly positioned on top of the rig.
- Storage / Sump Tank: The large rectangular blue base cabinet, which stores the fluid (typically water) circulated through the testing circuit.
- Pressure Indicators: Two dial pressure gauges arranged inline to measure the system’s static pressure differentials at the suction (inlet) and delivery (discharge) points.
- Piping Network & Valves: Off-white piping pathways fitted with manual flow control valves to introduce system resistance and alter flow rates during live tests.
General Educational Applications
The setup is utilized by engineering students to determine and graph the standard performance relationships of hydraulic pumps, focusing on:
- Total Head vs. Discharge Rate (H vs. Q)
- Brake Horsepower vs. Discharge Rate (P vs. Q)
- Overall Efficiency vs. Discharge Rate (η vs. Q)
