Roller-pack bearings are precision bearings made specifically for the machine tool axes to provide precision positioning of the axis under heavy load. The Roller Pack Machine Tool Axis Learning System adds Mechanical Drives 1 Learning Systems to teach machine tool axis drives based on the roller-pack type bearing. Students will learn industry-relevant skills related to this new topic including operation, installation, performance analysis, troubleshooting, and design.
The axis can also be combined with the ball screw components of the Mechanical Drives 4 System to become a fully operational machine tool axis. The Roller Pack Machine Tool Axis Learning System includes 12 roller-pack bearings and other components to assemble a machine tool axis; student learning materials for both theory and lab, and teachers guide.
Features:
Industry-relevant skills
Teaches machine tool axis drives based on the roller-pack type bearing.
Experiments:
Study and understanding of the operation of a chiller unit
Detecting the system operating parameters
Plotting of the refrigerant cycle on a pressure-enthalpy diagram of the refrigerant gas
On-off control of the cooled water temperature
Plant start-up and system monitoring using the incorporated protection and safety devices
Calculation of thermal balances for the refrigerant and water circuit
Safety control using the high and low pressure switch and flow switch.
The Study of Microcontroller
....
A self contained bench top service unit designed to provide services for up to five different chemical reactors:
Transparent Batch Reactor
Plug flow reactor
Continuous Stirred Tank Reactor
Tubular Reactor
Laminar Flow reactor
Fully computer controlled and supplied with educational software (32/64 bit) specific to each reactor type. Simple interfacing to the (user supplied) computer by a USB interface
Provides PID temperature controlled hot water in order to maintain reactor temperature.
Complete with two thermocouples, an input for a third (user) thermo couple and a dual range conductivity sensor.
Two peristaltic feed pumps with individually variable flow rates, 0-140 ml/min.
The Controller is for use with most products in Control Engineering range, but it will work with any other compatible laboratory equipment.
These blocks mimic the important parts of industrial controllers. Clear diagrams on the front panel of the controller show the blocks, each of which has its own set of connection sockets. This compact unit has analogue electronic circuits connected in blocks. The user connects the blocks in any way that they need and then connects them to their chosen products in the range.
The blocks include:
Fully adjustable potentiometers that can work as setpoints or attenuators
A function generator and digital voltmeter
Proportional and integral blocks
A complete three-term PID (proportional, integral, derivative) block
Phase lead
Summing junctions.
The controller can operate as a configurable PID controller and as a 2-point controller. In the latter case, as well as the setting of the reference variable, the hysteresis can also be pre-set. The recorder function provides continuous recording of controlled, manipulating and reference variables. The software ideally supports the experimentation and learning process of demonstration models. Its key features are the software controller and the recorder function. It plots responses to changes in the reference (e.g. step input) and disturbance variables. The controller included with each demonstration unit can also be used instead of the software controller. Measured values can be printed out and saved to data media. Connection to a PC is by a USB port. The supplied USB interface module provides an adequate number of analogue inputs and outputs, enabling even complex circuits, such as a cascade to be controlled. In this case, controlled, manipulating and reference variables can be plotted, displayed and saved by the program's recorder function.

The PLC Programmable Logic Controller And Automation Training System has a built-in powerful industrial PLC employing the latest technology features which allows the management of all the typical variables of an industrial process. The PLC Programmable Logic Controller and Automation Training System is today the core of most of the control systems. The PLC programs can be managed by a PC and dedicated software for Windows. The system is supplied with manuals which describe all parts of the unit, the installation and utilization procedures, as well as many exercises with the relative results. In fact, very often in any automated system the commands and controls are processed and executed by PLC. The unit makes available in a single structure all the equipment required to carry out exercises at any level of complexity, from the simplest to the most demanding.
