The programme of exercises enables familiarisation with six different drive implementation and analysis methods: understanding the brief and the drawing, assembly, setting, adjusting, testing, and making calculations. This laboratory system is used to introduce the basics of gearing and the correct method of assembling drive elements. A robust tubular steel frame with a square profile and bearing elements provide the accuracy for the setting of precise gearing. All the system components are kept ready to hand and well protected in a housing system. Offers three assembly kits in this product series, each focussing on different aspects. Each kit is used entirely independently of the other kits within the series. The flexibility of the set-up and the modularity of the components simplifies experimentation and implementation of the students' own ideas.

Compact Series And Parallel Pump Test Set Multi Speed is a self contained bench top unit for studying the series and parallel pump characteristics at three different speeds. By manipulating flow control valves, each pump can be operated individually or both pumps connected in series or parallel. The unit consists of two centrifugal pumps with multi speed motors and a storage tank on a steel base, and measuring instruments.
Experiments:
Flow rate vs head at a fixed speed for two pumps connected in series or parallel.
Flow rate vs head at various speeds for individual pump.
The equipment uses normal clean dry air, as it behaves as an ideal gas over the range of pressures used in this equipment. A thermocouple measures the temperature of the heater surface for the controller. Two thermocouples measure the temperature of the air in the vessel. A pressure transducer measures the pressure of the heated air in the vessel. A hand-operated valve at the bottom of the vessel allows students to normalize the air in the vessel to ambient conditions. A digital display shows the absolute pressure, both temperatures and their average value. The bench-mounting equipment includes a back plate that holds a low-pressure vessel. The vessel holds a fixed volume of air surrounded by an insulated heater, controlled by an electronic temperature controller. They then record the changes in pressure as the temperature increases and plot the results to prove Gay-Lussacs Law. Students set the controller for the range of temperatures needed during the experiment.
Experiments:
The principle of a vapour pressure thermometer.
Demonstrates change of pressure of a fixed volume of gas during heating.
Proving Gay-Lussacs Law by experiment.
A reversible flat plate located inside a rectangular duct. The duct has removable profile plates that can establish an increasing or decreasing pressure gradient in the direction of flow. The plate has one smooth and one artificially roughened face.
This may be moved toward the plate in measured intervals using a micrometer adjustment. The growth of the boundary layer along the plate may be investigated.
To investigate the growth of the boundary layer profile in a variety of conditions along the plate a micro- tube is provided.
The pump has a very simple and robust set-up and never the less has a very high capacity. The pressure and suction valve and the oil duct are cut open. If the rotor is turned, the enlargement and reduction of the working area can be seen particularly well, as can the contact of the slide shoes in each position of the vane. In order tosupply a vacuum for brake boosters, vacuum pumps are used in both diesel and,increasingly, in Otto engines.
