For example, if a doorbell does not ring when it should, it is only by means of a systematic approach that one determines that the bell itself is faulty. Bag Length is inconsistent. Locate fault based on analysis, 4. Removing parts of the circuit and testing to see if the fault is still present can also be used to find ground faults. This will usually pinpoint which specific circuit is faulty. connections, open-circuits, short-circuits, device faults (mechanical), supply faults. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. In addition a maintenance aid to fault-finding. This is because the processes of detecting and localizing the fault are happening at basically the same time, both done by the Fault Detection and Isolation (FDI) algorithm. In this case, the most stringent predictive maintenance program should be adopted despite its high cost. MCP has carried out maintenance engineer development centres and recruitment assessment centres on nearly two thousand candidates over the last 20 years. Here are six key points to consider: 1. However, due to consistent advancements in microprocessor-based controls, automation, real-time data acquisition, and systems like Fault Detection and Diagnostics (FDD), the way in which we perform equipment maintenance has been significantly transformed. Tell us your team's CPD needs and we'll come to you with a specialised training programme, customised for your engineering sector. The quantity of information collected is unimportant, what matters is that all information collected is relevant. Sometimes removing the cause of a system failure is not enough, and the fault must then be rectified. What are the fault finding techniques to be used when the equipment fails to operate correctly? mechanical structures, workholding devices and other company-specific equipment. For instance, upon breaking of rotor bars, the pulse produced in the stator current is twice the motor stator current frequency. h! It does not store any personal data.

Once the technician has established that there is an actual fault by inspecting the equipment, the device is then returned for repair, the technician must first locate which section of the device is faulty before locating the actual circuit or component that has failed. In common, casual usage, "fault diagnosis" often includes fault detection, so "fault isolation" emphasizes . We draw on the real-life experience of the course tutor and on established good working practice. With the advent of fast computing technologies, big data processing, and advanced learning algorithms, traditional fault detection has evolved into automatic fault management systems that not only detect faults, but also identify the root cause and implement corrective actions to avoid future recurrence. Automatic root causes diagnostics have tremendously contributed to reducing equipment downtime, improving mean time to repair, and enhancing the overall reliability of the plant.

Pure probability. If a mechanic can easily see all of the historical work orders, inspections, and parts associated with a piece of equipment, it's easier to narrow the list of possible causes of the failure. Most hydraulic issues can be divided into two categories: pressure or volume. Gather Information Ask people when & how the fault occurred. One example of model-based fault detection is the use of time-domain reflectometry (TDR) to detect faults in underground cables. 1 What are the fault finding techniques to be used when the equipment fails to operate correctly? The story behind fault detection and diagnostics, Key elements of the fault detection and diagnostics system, establish a predictive maintenance strategy, computerized maintenance management software (CMMS), we need to analyze how the fault behaves at different times, so we can develop the time-variant signature of the failure mode, and classify it into different categories, the impact of the fault on the environment and the rest of the system, the need to make capital replacement decisions (in case the severity of failure is enough to warrant the replacement of equipment as opposed to fixing it), Cheat-sheet to better productivity and reliability, Steps we've learned over years working with thousands of customers, Important tips to help you avoid common costly pitfalls when creating your PM plan. Although you still have to find out what is wrong with this switch and fix it, at least you've identified the culprit. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis of the discrepancy between the sensor readings . 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. Pulling film down the forming tube is difficult. In some applications, fault detection and isolation go hand in hand; they can, of course, be separate modules of the process. Fault finding techniques on pieces of electrical power equipment. That's why fault diagnosis techniques have been developed for these systems as well. The programme explores the fundamental principles of commissioning. In this case, the less stringent maintenance strategy such as run-to-failure or preventive maintenance could be sufficient to manage the risk. More often than not, the underlying failure modes are mechanical in nature and associated with the rotary part of the motor: shorted rotor windings, bearing failures, and rotor breakdown. This is done to improve the accuracy of isolation and reduce the impact of downtime. The 6-point fault finding technique is a method for finding and fixing mechanical operating malfunctions.

Analytical cookies are used to understand how visitors interact with the website. If the equipment is unable to discover the right failure mode (or if detection is incorrect and triggers false alarms), then the isolation, identification and evaluation will also be ineffective. Failure codes can also be used to uncover a common problem among a group of assets and determine a long-term solution. Here w share our Ten Top Tips for a successful training programme. However; this practice could cause further complications in the repair of the plant or process. It is the most important stage of FDD as all of the downstream processes depend on its accuracy. Applying this approach. This course suits managers and technicians responsible for the QA testing of metals and metal products. In the early days, equipment maintenance was restricted to repairing faulty assets and performing basic routine maintenance based on rigid time intervals. Also an intuitive approach can be used but must be accompanied by a deductive technique. Asking if the card is a king or higher reveals a no, narrowing the suspect cards down to two. Another simple rule-based detection example comes from the series operation of bottle filling, capping, and packaging system on a conveyor belt system. ", "Honestly - the customer support has been fabulous. Degegates will have developed a good working knowledge of basic fault finding techniques and methods which should make them more effective and efficient with problem solving faults on their workplace systems. Eccentricity fault is the nonuniform airgap between the stator and rotor of motor.

Chapter 3: Fault Diagnosis and Rectification. This is because the increased cost of maintenance is warranted to prevent major fallout that will be way more costly. Copyright 2023 Limble CMMS.
What other benefits can a multi-skilled workforce bring. If the fault magnitude is low, the system just needs to be able to endure the fault for an extra time until the fault is cleared by itself. Or want to train a group in house? Determination and Removal of the Cause. Smart sensors perform self-diagnosis by monitoring internal signals for evidence of faults. We have a range of options to help you maximise your training budgets. This GLOMACS training course will allow delegates to interact and gain shared experiences of others along with: An understanding for the need for routine inspection and maintenance. When you're doing an RCA to determine the source of a fault, you'll usually find 3 basic types of problems: physical causes; human causes; organizational causes; You can also do a root cause analysis if you want to drill down and find out exactly why a process or procedure is producing better-than-average results. Turn all switches off again. Half-split again by asking if the card is a jack or higher. It may not always be parts of a circuit you're trying to eliminate. If there is no fault, proceed to the next step. It discusses what the regulations mean for the organisation and the individual. With more sophisticated equipment or systems, it may necessary to fine-tune the system in order to return it to optimum working conditions. Moreover, the necessary alarms can be triggered and fault diagnosis can be conducted, so the operator/technician can take appropriate action. How is a fault finding technique that works? 3 What device can be used for checking electrical problems? With every step in the process, the troubleshooter eliminates half the circuit as the cause of the problem. Common Motor Failures and Faults.
