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.

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.
The Piping Loss Apparatus Large is intended to be used with a Hydraulic Bench or an outside water supply. Friction loss is measured by a pressure drop and coefficient of discharge is determined from a pressure drop and a flow rate. Piping Loss Apparatus Large is a comprehensive unit for studying the friction losses in pipes, pipe fittings, and valves and to determine coefficients of discharge for primary flow measuring devices at various flow rates. The pressure drop is measured by differential pressure using manometers. Pressure tapping in by valves with quick connection. All pressure taps are connected by flexible hoses to a set of specially arranged manifolds such that differential pressure across any component can be measured simply by opening valves without removing the hoses. All friction loss components and the flow measuring devices are arranged on a water proof panel which is attached to a floor standing steel frame. Flow rate is obtained from a water meter and a stop watch.

The parts are clearly laid out on a base plate. All parts are precision-manufactured on CNC machines and feature standard engineering tolerances and surface finishes. The surfaces of the parts have a gunmetal finish to prevent corrosion. The kit contains all the parts required to assemble a functional lever press. Multiple trays are stackable, providing for space-saving storage. The kit is ideally deployed for student exercises during teaching, with two/three students able to work with each kit. As well as the primary technical drawing focus of the teaching, other topics that can be covered include machine elements, assembly processes, and manufacturing technology. The comprehensive and clearly structured instructional material is laid-out in line with modern principles, and is of great help with lesson preparation. The lever press model can be considered as a project enabling interdisciplinary, action-oriented teaching.

The Hydrostatic Pressure On Submerged Surfaces system is designed to study and calculate of the pressure force acting on a submerged surface Hydrostatic Pressure On Submerged Surfaces is a simple and completely autonomous equipment that can be easily located in a laboratory without any installation.
It is possible to use liquids of different densities to determine the different exerted forces between them.
With this equipment it is possible to perform the following experiments:
Obtaining and verifying the momentum created by pressure force acting on a submerged curved surface.
Measure and verify the momentum created by the pressing force acting on a submerged flat vertical surface. For that it is necessary to determine both the magnitude of the force and its pressure center. It is possible to distinguish two different cases:
Partially submerged surface.
Complete submerged surface.
Hydraulic cylinder with hydraulic pump to generate pressure
Hermetically sealed hydraulic system, maintenance-free
Investigation of the stresses and strains in a thin-walled cylinder under internal pressure
Strain gauge application on cylinder surface at various angles
