• ‘Sci-Cal’ Computer Control Software & Interface in ‘LabVIEW’ Software for data acquisition, visualization and operation1

Gear pumps belong to the group of positive displacement pumps with a continuous flow. Two counter-rotating gears transport the medium from the intake side to the delivery side. The transported medium is between the housing and the tooth spaces. The pulsation-free flow increases linearly with speed. These pumps are particularly suitable for the generation of medium-high pressure at low flow rates.

The experimental unit provides the basic experiments to get to know the operating behaviour and the most important characteristic variables of gear pumps.

Sci-tech Gear Pump Test Apparatus Model FM 085 features a closed circuit with a tank and a gear pump with variable speed via frequency converter. The pump gears are mounted in a transparent housing and can be observed during operation. Flow rate and head are adjusted via a needle valve and an overflow valve. Oil is used as the medium.

The experimental unit is fitted with sensors for pressure and temperature. The oval wheel meter is especially used for the accurate flow measurement of viscous liquids. Oval wheel meters operate on the positive displacement principle with two precise oval gear wheels.

Optionally ‘Sci-Cal’ Computer Control Software & Interface in ‘LabVIEW’ microprocessor-based measuring technique is well protected in the housing. All the advantages of software-supported experiments and evaluation are offered by the software and the microprocessor.

The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
