HM 286 Experiments with a Gear Pump

description

The HM 286 demonstration unit enables the operating behaviour of a gear pump to be investigated. These pumps are particularly suitable for the generation of medium-high pressures at low flow rates. In practice this type of pump is predominantly used in oil-based hydraulics. The demonstration model consists of a system of pipes made of steel and a tank made of Plexiglass. Electronic sensors provide the flow rate, relevant pressures, the temperature of the pumped medium as measured values. The pump output can be changed using a needle valve. The software for data acquisition and visualisation makes the experiments especially clear and enables fast execution of experiments with reliable results.
