Description of Compact Series And Parallel Pump Test Set Motor Dynamometer

Compact Series And Parallel Pump Test Set Motor Dynamometer is a self contained bench top unit for studying the series and parallel pumps characteristics. The unit consists of two sets of centrifugal pump and motor dynamometer for measuring true pump input power, a storage tank, on a steel base, and measuring instruments. Speed control is by two inverters. By manipulating flow control valves, each pump can be operated individually or both pumps connected in series or parallel.

Experiments of Compact Series And Parallel Pump Test Set Motor Dynamometer

1. Flow rate vs head at various speeds for individual pump.
2. Flow rate vs head at a fixed speed for two pumps connected in series or parallel.
3. Power input, output and true efficiency at various speeds for individual pump and two pumps connected in series or parallel.
