mechanical fault finding techniques

Even better when you consider our business is located in a completely different time zone (somewhere in Australia). The programme explores the fundamental principles of commissioning. Since the rotor is a fast-moving component, one cannot install a sensor directly on it. Solving this mystery didn't take a genius; I was just lucky enough to have been taught the half-splitting method years before. 3 0 obj as you would save travel time. The last step in the process is to check the system and make sure it can return to operation. If the fault is not obvious it becomes necessary to trace the system through from beginning to end looking for a loss of function. A yes takes us down to four cards. The areas or regions are systematically reduced in size until a specific part can be identified as being faulty. John Saysell, Training Director at MCP Consulting Group, explains how investing in training is helping the Lucozade plant meet the manufacturing challenges of the future. 1. Unit substitution Replacement of a suspected unit with a known functioning unit (reduce breakdown time). Do you need underlay for laminate flooring on concrete? Analyse Information decide the probable cause. Half-splitting can also be used in all types of circuits, not just series-wired switches. All rights reserved. This could be a switch out of adjustment, a broken or loose wire, a safety door open, or pressure too high in the system. 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. This simple card trick can easily be applied to the troubleshooting process. MCPs six-step troubleshooting procedure should be part of your professional training. Faults can be classified as: Positive fault sustained fault mechanical etc. Example 1: You're working on a CNC machine tool with X, Y, and Z-axis drives. A range of options to help you maximise your training budget. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. In TDR, the signal is sent across the test cable and is received after being reflected from the point of fault. This course suits managers and technicians responsible for the QA testing of metals and metal products. Check the machine or system 5. In the case of the puncture, it is easy to confirm that the cause of the fault and the fault itself has indeed been dealt with satisfactorily, assuming that the tyre remains inflated. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Context is vital when troubleshooting equipment failure. On existing plant add-in the equipment you need for problem-solving. Therefore, intelligent fault diagnosis becomes a hot topic and it includes the following three steps: signal acquisition, feature extraction, and selection based on the signal processing techniques, and fault recognition based on artificial intelligence techniques. 2023 Institution of Mechanical Engineers. Mechanical faults such as eccentricity and bearing faults are seen commonly in rotating machineries.

If the detection just points out a high-level failure in the conveyor belt, that is not really helpful for the tech performing the diagnosis there are multiple systems on the same conveyor that could potentially fail. Nevertheless, the Fault Detection and Diagnostics algorithm for any equipment should contain at least the four key processes listed below (these can constitute a nonlinear process as well, provided that some steps happen at the same time): We need to discuss each element in more detail to really understand how fault detection and diagnostics work. With more sophisticated equipment or systems, it may necessary to fine-tune the system in order to return it to optimum working conditions. 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. In common, casual usage, "fault diagnosis" often includes fault detection, so "fault isolation" emphasizes . When using the technique, you will have to narrow down a fault to its source. All the evidence collected must be relevant to the problem in hand. As each subsystem is proven move to the next until the faulty subsystem is found. Tell us your team's CPD needs and we'll come to you with a specialised training programme, customised for your engineering sector. This is the third crucial skill for troubleshooting: half split, measure, and move. BP. <>>> 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. Contrary to popular belief, the act of troubleshooting is not always about your tools; it's often about your mind. Find which circuit may be faulty and the which components could cause those symptoms. Step 6 You will be expected to use a variety of fault diagnosis methods and techniques, and to utilise a number of diagnostic aids and equipment. Best Answer. For safety reasons, all of these doors must be closed in order for the machine to operate. Turn the electricity back on. Gather Information Ask people when & how the fault occurred. Here are six key points to consider: 1. The FDD, as the name implies, contains the detection and diagnosis of equipment failures. Design extra equipment into a new plant for problem analysis. You continue halving your search group until you find the source of the issue. 4) touch temperature rise, vibration . As an industrial electrician, you'll encounter many complex electrical circuits and drives that will break down as they age. Once the collection is complete, an analysis to consider the validity of the information collection begins. The next question solves the problem. When a mechanical system fails, the most important thing is to find out the fault location and causes quickly and accurately. Rectification of the Fault. Pulling film down the forming tube is difficult. 2013-05-01 08:55:01. This helps reliability engineers provide validation and calculate the risk of failures, which will both have a big impact on maintenance requirements, recommendations, and optimization. With this one measurement, you've proven the functionality of the other five switches. What are the fault finding techniques to be used when the equipment fails to operate correctly? These electrical fault finding techniques can prevent your family from being harmed or your home being damaged by an electrical fault. If no voltage is present, but we know that the circuit control voltage is functioning for other parts of the same control circuit, this would lead us to believe one of our 10 switches has a problem. Lets use a high voltage and high power three-phase AC induction motor as an example. What is the six point fault finding technique? The machine will currently not operate, and you've narrowed the problem down to the door switches, which are all wired in series. Tell us your team's CPD needs and we'll come to you with a specialised training programme, customised for your engineering sector. Basic tips. For instance, a flat bicycle tyre might be the result of a puncture (the fault) in the inner tube. 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. More about in-house and tailored training, Design and development of processes, systems, services and products - For Chartered Engineers: Apply appropriate theoretical and practical methods to the analysis and solution of mechanical engineering problems This course is for engineers and technicians who require a better understanding of the methodologies they can apply to fault-finding, regardless of system type. I can give you several sentences.Use that ingredient as a substitution for the one you don't have.He is going in as a substitution for the . Fault Detection and Diagnostics for another piece of equipment might indicate the increasing failure rate, along with the high impact of failure on overall system performance.
