The trainer contains a pipe system with two circulating pumps. It is possible to switch between series and parallel operation using ball valves.
Two rotameters with different measuring ranges are provided for the measurement of the flow rate. Manometers indicate the pressure at all relevant points in the system. The temperature can be read on a bimetallic thermometer.
The trainer has a closed water circuit with expansion vessel and is thus independent of the water mains.
Learning Objectives / Experiments
Pump characteristics at varying speeds
Determination of pipework characteristics and operating points
Series operation of circulating pumps
Parallel operation of circulating pumps
Comparison of experiment and calculation In conjunction with other training panels in the trainer for heating and plumbing system series, it is possible to set up a complete heating system.
