PRODUCT
HL 107 Circulating Pumps Training Panel
Education / GUNT Hamburg / Thermal Engineering and HVAC / Heating and Ventilation in Buildings /
description

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 HL 100 series, it is possible to set-up a complete heating system.
