The Pneumatic Troubleshooting Learning System is set up with realistic loads, pressures, and heavy-duty pneumatic components, just like learners will see in the workplace. The features also make the Pneumatic Troubleshooting Learning System an excellent system for teaching advanced pneumatics, as well as pneumatic system tuning, installation, and maintenance. Pneumatic Troubleshooting Learning System models a real-world electropneumatic troubleshooting machine, driven by MicroLogix 1200 programmable logic controller, and features over 30 electronically-inserted pneumatic, mechanical and electrical faults using state-of-the-art fault insertion software. Understanding how to troubleshoot problems that arise in pneumatic systems is a vital industrial skill that is irreplaceable for maintenance technicians and others in industries like packaging, pharmaceutical, automotive, and more. These components will be used to cover major topics like vacuum pick-and-place, rotary actuator operation and troubleshooting, air-over-oil system operation and troubleshooting, and quick exhaust valves. Learners will immediately practice applicable hands-on pneumatics skills after studying each topic to increase understanding of how theoretical concepts are directly related to the real-world pneumatic troubleshooting applications. The Pneumatic Troubleshooting Learning System includes real-world components such as pressure gauges, pneumatic cylinders, pneumatic motor, directional control valves, flow control valves, limit switches, and more.
Features:
Computerized fault insertion system avoids damage to equipment
Computer-based fault insertion
Pre-mounted components, industrial fittings, and standard connections

This valve sets the temperature of the boiler return flow and the feed flow. Cold water connections enable the heat generated to be dissipated. A pump circulates water through four radiators. The temperature of the radiators is set using thermostatic valves.The differential pressure across the pipe system is limited using a relief valve. Temperatures can be read on dial thermometers. A digital controller keeps the room temperature constant by driving the four-way mixing valve.

A force board is clamped into the working area of Universal Frame and Stand single and double pulleys sets can be fixed round the perimeter of the to produce an infinite variety of multi-directional forces in a vertical plane. Two cord rings held together by a short cord are used for non-concurrent force experiments. The lines of action of the cords are transferred onto a sheet of paper clipped to the force board using the board clips provided. By using a single cord ring (concurrent forces), up to six cords can be attached and the cords tensioned with load hangers and weights to obtain Equilibrium of Forces. The set of weights for the experiment is included.
