The assembled element system - journal bearing or gear unit - is mounted on the test bed. Here, the complete system is properly assembled, with particular regard to the alignment of the system components. The units (shaft with journal bearings) and (combination gear units) are tested with unit. A successfully completed assembly project can then be examined in operation with a formal final test. Parameters examined during test procedure are; running noise, heat generation, vibration or leakage. The T-slots allow the installed length to be varied, and therefore can be easily adapted to the drive element. Two couplings connect the element system to the motor and the brake. Includes a single-phase asynchronous motor drive, a magnetic particle brake with adjustable braking torque, and a rigid machine bed with T-slots on which the motor and the drive element under test are mounted. The controls are on the switch box. The braking torque is set here using a potentiometer. The students must align the connections between the motor and the element system, and between the element system and the brake.

The Internal Combustion Engines Test Bed is perfectly vibration free and can be installed in any room or laboratory. Engines are quickly and easily installed on the test frame in pairs, to be tested in rapid succession. In its design, all teaching needs have been taken into account, together with practical requirements, in terms of installation and replacement of the engines to be tested.
Internal Combustion Engine Test Bed has been specially designed for use in testing laboratories, and to ensure the greatest possible teaching effectiveness in the field of i.c. engines. A data acquisition and analysis system for Personal Computer, called SAD/End, is available and make it possible to perform several functions automatically taking measurements, displaying torque and power curves on screen or printing them out, filing the test data on disk, or printing them out. The engines are coupled to a dynamometric unit for the determination of torque and power values.
A separate instrumentation console allows measurement and display of the engine torque, speed, air consumption, fuel consumption, inlet air temperature and exhaust gas temperature.
A floor mounted modular internal combustion engine test stand with regenerative dynamometer and a range of optional internal combustion engines up to 4kW shaft power.
The unit is supplied with a detailed experimental operating and maintenance manual giving example experimental results and sample calculations.
An optional computerized data acquisition upgrade is available that allows all relevant system parameters to be automatically recorded on a PC.
Accessories and spares for two years normal operation together with a full two year warranty are also included as standard.
Possible Demonstrations:
Function of a differential gear
Synchronization
Shifting all gears.
The structure of the electric control line components is plank and hanging box.
Device is provided with a voltage - and current leakage protector, which can make sure of the operators safety.
It can be used as electrical instrumentation and lighting circuits operating training device. And it can also be used in Labor Occupational Skill Testing departments, colleges, vocational school, and technical school of the early, middle and senior maintenance electrician skills assessment.
Training circuits and devices are connected to secure socket and highly reliable pistol inserted wire sheath structure.
All components are leaded to the terminals by wire. And apprentices just need to wiring on terminals.
It can be carry out process training and conduct trace walking.

This patented and unique engine features transparent engine construction, which exposes all the moving parts of a 4-cycle engine. Since the is oil-less too, it enables the students to observe clearly the crankcase components and internal combustion of the engine. The Oil Less Four Cycle Multi Fuel Engine Performance program has made the study of 4-cycle engines a simple task and opened the door for the student to conduct multiple experiments in alternate fuels. Includes variable timing and compression.
