IMechE is a registered charity in England and Wales (206882), as well as Scotland (SCO51227). Copyright 2023 Limble CMMS. mechanical etc. Plus, when the machine finally becomes operational, no one has learned anything because so many random things were done. Although it is difficult to achieve a sensor that can carry out self-diagnosis of all possible faults that might arise, it is often possible to make simple checks that detect many of the more common faults. The purpose of this article is to present an overview of Fault Detection and Diagnostics as they are applied to improve the equipment maintenance process and boost asset reliability. This is also where I would have a quick look at the safety relay which has indication lights on it to indicate ready state or fault state. This piece of equipment has 10 safety switches that have to have their contacts in the closed position before the machine can operate. Troubleshooting a pneumatic system is neither art, nor science, nor should it be viewed as hit-or-miss; it is a procedural effort requiring 12 steps to accomplish. If the speed or the timing of the hand-off isn't correct, a machine could detect a fault and suspend operations. Bag Length is inconsistent. Another simple rule-based detection example comes from the series operation of bottle filling, capping, and packaging system on a conveyor belt system. Analyse the Evidence. Here we outline two alternative approaches to achieving competence. Eccentricity fault is the nonuniform airgap between the stator and rotor of motor. Pure probability. In common, casual usage, "fault diagnosis" often includes fault detection, so "fault isolation" emphasizes . What other benefits can a multi-skilled workforce bring. If the circuit control voltage is still present, then the five switches between that point and the source are closed, leading you to believe the problem is in the five switches between your voltmeter leads. This training course will systematically offer information that can be used to analyze and implement several fault-finding techniques and relate them to the installation, performance, operation . The first question would be, Is your card red? Let's say he says no. Now we know the card is black, having already eliminated 26 cards from the deck not too bad with one question. This could be a switch out of adjustment, a broken or loose wire, a safety door open, or pressure too high in the system. For instance, upon breaking of rotor bars, the pulse produced in the stator current is twice the motor stator current frequency. Solid-state electronic AC motor drives are becoming more A range of options to help you maximise your training budget. zPFM-H*3TMreU,hVN:$jia9q8^ ]UC(^7YXg88$dc9jqH6G6G6G6Y#eTURl,ZaXz Design extra equipment into a new plant for problem analysis. Is your card a queen? Another no, and we know the card is the jack of clubs. Our old Maintenance software was very difficult to use and was very expensive.". If the cause of a fault is not removed, the fault will recur even though the fault has been rectified. Let's take a look at some electrically focused hypothetical examples to further explain this method. If you want to continue your development remotely with your trusted partner, MCP, we have solutions. The returned pulse signal from the cable simultaneously indicates the presence and the location of fault through time and velocity of the returned pulsed signal. Preventive Maintenance is done before a failure occurs and consists of maintenance types like: Time-Based Maintenance, Failure Finding Maintenance, Risk-Based Maintenance, Condition Based. Once the collection is complete, an analysis to consider the validity of the information collection begins. If not, replace the faulty component.
