Industrial Machines Control Assembly Training Stand Kit
....
The two-stage gear unit kit contains all the parts required to construct the gear unit. All parts are clearly laid out and well protected in a sheet-steel tool box. Small parts are supplied in a box with a transparent lid. This assembly exercise permits wide-ranging and, above all, interdisciplinary work to be carried out by the students. It consists of a spur gear stage as its input, with a downstream worm gear stage (multistage gear combination). The fit seatings of the gear unit are designed to allow the complete assembly process to be carried out by hand. This, in conjunction with students working in an independent capacity, as well as developing team working skills, ensures that the unit serves as an excellent learning tool. The project unit is particularly well suited to action-based teaching.

The unit consists of a pump, a storage tank and a water proof panel on which all friction loss components and the flow measuring devices are arranged. Friction loss is measured by a pressure drop and coefficient of discharge is determined from a pressure drop and a flow rate. Piping Loss Test Set, Large is a self contained water circulating 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. Flow rate is obtained from a water meter and a stop watch. 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. The unit is on stainless steel frame on wheels. The pressure drop is measured by differential pressure using manometers. Pressure tapping is by small ball valves with quick connection.
