mechanical fault finding techniques
An example might be a conveyor belt that will not move when started. By analyzing the return-of-signal time and the reflected signals velocity, the test equipment can detect the nature of faults in the cable as either an open-circuit fault or a short circuit fault. 6 What to do if there is no fault in a safety relay? Injection and sampling
Location of a defect or fault found through inserting known data signals or functions at selected test points of the system or process. Electrical faults typically result from either an open circuit or a short circuit but can also be a combination of these. For instance, consider the example of TDR testing for underground cable. What are the fault finding techniques to be used when the equipment fails to operate correctly? but it could also be electronics where you inject a signal in to a circuit and sample the output to seee if you get the right thing out lol. As an industrial electrician, you'll encounter many complex electrical circuits and drives that will break down as they age. As a general rule, the technique of swapping identical components should be used only when there is minimal chance of causing additional damage. Failure codes are useful when maintenance troubleshooting because technicians can immediately see common failure codes, determine the best solution, and implement it quickly. Control Circuits (Internal Fuses) - Contactors (Breakdown of Parts) - 3PH motors (Loss of Phases &/Or burnt out coils) - Single Phase Motors - (Carbon Brushes) Initial Faults on newly Installed work Reversed Polarity - Discrimination - loose connections - Protective Devices -Faulty Portable equipment - (NB: Cannot be 'ware and tear') 3 0 obj
Fault finding for maintenance Engineers Half splitting and unit substitution Aims and objectives By the end of this session you should: 1) Understand the half split technique. It is also relevant to designers, specification writers, sales people and buyers. The FDD, as the name implies, contains the detection and diagnosis of equipment failures. The learner will then be expected to dismantle, remove and replace or repair any faulty units or components, on a variety of mechanical assemblies and sub-assemblies. endobj
You have 10 left, so half-split those by checking five of them. What is a sentence using the word substitution? 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. At least, the way I see it: There are 9 types of maintenance split between Preventive Maintenance and Corrective Maintenance. Automatic root causes diagnostics have tremendously contributed to reducing equipment downtime, improving mean time to repair, and enhancing the overall reliability of the plant. For safety reasons, all of these doors must be closed in order for the machine to operate. Example 1. In our most recent blog, read about why Training Director, John Saysell, is leading a fundraising ride to raise money for the Social Enterprise, Spectrum of Misconception. xMoA+ #Ji@@Y!Pzhe3qyLf/OptgMy;fc_>zZh9k\1F

In some cases, the algorithms are sophisticated enough to even initiate failure containment actions to auto-correct the failure itself and restore the equipment to its healthy condition. Engineering projects come in all shapes and sizes and require a variety of skills to your projects on track and within budget, often whilst managing multiple projects at the same time. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. In this case, the most stringent predictive maintenance program should be adopted despite its high cost. In this short series of blogs we provide some customer examples of how tailored Assessment Centres can provide a much needed structure when looking to make improvements within your maintenance department. Is your card a queen? Another no, and we know the card is the jack of clubs. 3 Fault Diagnosis for Mechanical Drives The motion transmission systems play an important role in every engineering system because they are the ones which transfer the power developed by the actuating systems. Trouble is reported on a machine that will not start. Once the collection is complete, an analysis to consider the validity of the information collection begins. These cookies ensure basic functionalities and security features of the website, anonymously. Only 2-5 percent of system faults are symmetrical faults. You also have the option to opt-out of these cookies. To help technicians get to the cause of a fault faster, MCP has developed a course focusing on a logical approach to fault finding. 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. Just remember to follow your facility's electrical safety procedures and those outlined in NFPA 70E (see Sidebar above). Such automation of a series of manual processes has enabled reliability and maintenance engineers to apply predictions on equipment health, derive future equipment performance, and shape optimal maintenance intervals. This helps us understand the impact of the different conditions the motor is subjected to, such as thermal rating, mechanical stress, or some other operating conditions that occur in special circumstances. The areas or regions are systematically reduced in size until a specific part can be identified as being faulty. Sample situations. The same data can be used to establish a predictive maintenance strategy over the remaining life of the motor. This is done by retrieving the parameters of equipment performance such as voltage, current, vibration, temperature, pressure and other relevant process variables while the equipment is working under normal conditions. Or want to train a group in house? You will be expected to use a variety of fault location methods and procedures, such as gathering information from the person who reported the fault, using recognised fault finding techniques and diagnostic aids, measuring, inspecting and operating the equipment. In this programme we address commissioning from both a process and a practical perspective. Each door has a normally open limit switch that is held closed when the doors are closed. These steps include collecting evidence, analyzing evidence, locating faults, determining and removing causes, rectifying faults and running a systems check. Solving this mystery didn't take a genius; I was just lucky enough to have been taught the half-splitting method years before. Fault detection is the process of discovering the presence of a fault in any equipment before it manifests itself in the form of a breakdown. 4 0 obj
Intermittent wiring faults occur because of dirty or poor connections, internally broken wiring and damaged wiring insulation. ", "Honestly - the customer support has been fabulous. If the cause of a fault is not removed, the fault will recur even though the fault has been rectified. 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. 9. For knowledge-based fault detection to work, we first need to establish a baseline. Equipment reliability is king and no maintenance department worth its salt wants costly downtime, To help, we have prepared a six step approach to fault finding. All the evidence collected must be relevant to the problem in hand. 5OJ QJ ^J h! Contact our advisors if you need help finding the most appropriate training for your team. What are the six key steps to approach electrical fault finding? Rather than checking each switch, check 10 of them first. Do you need underlay for laminate flooring on concrete? Application .

In fault diagnosis of mechanical equipment based on multisensor information, the key problem lies in how to make comprehensive use of all monitoring information. The algorithm then correlates the impact of these conditions on the degradation of bearing health and predicts the failure rate and health condition of the overall motor. Example 1: You're working on a CNC machine tool with X, Y, and Z-axis drives. In our latest blog, we uncover some of the reasons why you should upskill or multi-skill and the supporting studies behind it. Creases in film. This piece of equipment has 10 safety switches that have to have their contacts in the closed position before the machine can operate. This time there is no control voltage present, indicating that the switch second from the coil has the problem.
