SR362 Comparison Of Pumps Educational Equipment Hydrodynamics Laboratory
1. Description The experiments familiarise students with various pump types, such as centrifugal and positive displacement pumps. The trainer includes two centrifugal pumps, one piston pump as a positive displacement pump and a self-priming side-channel pump. The side-channel pump works primary as a centrifugal pump and, depending on liquid level, can also act as a Positive displacement pump. This means, as a special feature, the side-channel pump also permits gases to be pumped.
The pump is investigated pumps water in a closed circuit. In the process, the performance data of the pump and pressure losses in the pipeline are recorded. The centrifugal pumps can also be operated in parallel or in series configuration. Each pump is driven by a All of the motors of the centrifugal pumps is variably adjustable by a frequency converter. All motors are mounted on swivel bearings, so the torque can be measured by way of a force sensor, enabling the mechanical drive power Output to be determined. One free position is followed equipped with a reversible three-phase AC motor with variable speed. This position can be used for mounting of any pump.
Experiments demonstrate the basic operating lessons of various pump types.
