Functioning Of Electric Motors? Can Vibration Unbalance Affect The Functioning Of Electric Motors? Posted on March 18, 2013 by David Manney Click to View Post Reliability is an industry imperative when it comes to motor function. Motor vibration is a critical issue and likely to give rise to various problems. Vibration causes may include: Electrical imbalance in the circuitry Mechanical imbalances arise due to the defects in coupling, bearing, or other part. External imbalance effects that include base and shaft misalignment issues Speed of motor and the resonance produced can also lead to vibration unbalance Though this appears to be a small issue, it is likely to lead to great problems. The type of harm caused varies according to the type of vibration unbalance. The various problems induced by vibration defects are as follows. Driven Machine Imbalances Producing this type of imbalance occurs when the moving parts of the machine are offbalanced. When this imbalance crosses a certain limit, it can affect the moving parts of the motor thereby leading to motor damage. Coupling Imbalance When there is an improper arrangement of key and couplings on the frame, or there is some problem with alignment and mounting capabilities of the machine, this sort of imbalance is likely to occur. This condition may even include the usage of an oversized coupling. This may lead to bending of shaft, extreme imbalance, and rubbing of seals. If this imbalance goes beyond limits, it may result in catastrophic failure of shaft. Thermal Imbalance Rotor movement produces high temperatures, and when there is too much heating in an improper manner, the shaft may bend and the equipment alignment may be disturbed. This affects the rotor placement. Modal Shape and Natural Frequency Unbalance The stator core develops vibrations when applying a magnetic field. The frequency of these vibrations is associated with the modal patterns. In case, the modal pattern’s frequencies match, producing large resonance. This introduces serious vibration, and unbalances the running parts of the motor. Rotor Bar passing Vibration Unbalance When there is excess load on the motor, which induces stator current in the rotor bars, and this gives rise to passing frequency in the rotor bars. This frequency can be quite harmful to the motor if the tolerance limits are crossed. If this happens, the motor is unreliable, and the operations are unpredictable. The motor experiences imbalances in velocity, displacement, and stress in the stator core iron and stator tooth iron. 2 Google+ David Manney 2 Follow 73

Home Power Distribution You Reliability Hydro Product Sales Repair Services About Digital Thermography: See it Before it Burns You L&S Electric > Blog > Predictive Maintenance Programs > Digital Thermography: See it Before it Burns Digital Thermography: See it Before it Burns You Posted on February 19, 2013 by David Manney Our services are the best in the US and we're looking for team players! Curious? Use of digital thermography is one of the most effectively used techniques in monitoring equipment and machinery internal conditions in industrial field. This technique is used in proper verification of and measurement of the temperature of objects’ surfaces. Click to View Post With a precise and dependable conclusion it can be determined if there is high surface temperature in machinery or equipment surfaces. High surface temperature can lead to heat emission that can cause precious loss of energy. With the proper application of digital thermography technique it will be easier to create a reliable and precise output that allows the specialists to effectively evaluate back up and data software. How Digital Thermography Technique Works Technicians using digital thermography make use of special camera that is especially tailored to monitor the infrared emissions of energy. The camera has the ability to detect an object’s electromagnetic energy, which appears as a form of heat. The image taken by the camera is transferred as a video signal that generates the color image that will be used for a comprehensive data analysis. By saving the video signal, specialist can also create software back-up using the infrared thermography. Doing so allows for an elaborate evaluation of the gathered data for further and future analysis. Digital infrared thermography also lets technicians do proper temperature profiling of a machines’ point or surface. The technique makes use infrared based on the theory that every machine releases infrared energy, which is a form of energy that contains specific intensity as a temperature function. A machine’s surface temperature can be easily detected using an infrared scanning device or system. The thermal pointer and scanner, which are thermography instruments, work well together. The pointer measures the specific point or surface temperature and the scanner will record the surface’s thermal profile. Benefits of Using Digital Thermography There are many benefits of using digital thermography than any other techniques used. The first one is the simplicity in approximation of the amount of heat loss during surface temperature increase. With the application of digital thermography, there is the ease in estimating the amount of heat that is lost when there is an increase in surface temperature. Broken insulation can result to • Continued on Next Page 3

When defective areas are not immediately repaired, severe damage in equipment could be the result and there will be the need to purchase Click to View Post replacement to faulty units. Digital thermography allows provides non-invasive technique which means that it also works on specific parts of the equipment that it needs to deal with. Other parts will not be invaded thus are safe from any possible invasion damages. Industrial facilities gain a lot of benefits with the use of digital thermography, because this technique allows the plant manager to effectively establish if there is any possible malfunction in electrical machinery and motors. The plant engineer will be able to come up with the best solutions before the entire machine system shuts down because of the faulty or heated conditions. This significant feature of this technique prevents loss or decreased in the plant production. Another important benefit is that digital thermography allows the plant engineers to guarantee safety of the all plant machinery and equipment. When heat loss in machinery and equipment is prevented, the plant can save a lot of money, because they will be able to solve the issues of faulty and heated industrial units’ surfaces. Thus, business owners save money from unit repair or replacement. Early detection of possible malfunctions simply means early solutions to problems can be formulated. Therefore, costly repairs can be prevented and unit replacement totally eliminated. Use of digital thermography in determining the temperature of equipment, machinery and other industrial units, allows the industry to see the possible fault before it burns them down. 14 Google+ David Manney Follow 73 Related Posts via Taxonomies Rhinelander, WI may be next to lose a paper mill (2) Glossary of Useful Machinery Alignment Terms (2) Counterfeit Ball Bearings (2) Predicting Bearing Failure (2) Ultrasonic Detection Testing (2) Understanding Motor Power Factor (2) Introducing Ludeca’s New Laser Align App (2) Giving your equipment the finger.

Home Power Distribution Reliability Hydro Product Sales Repair Services About L&S Electric > Blog > Predictive Maintenance Programs > Giving your equipment the finger. Wait, what? Giving your equipment the finger. Wait, what? Posted on November 13, 2013 by David Manney Predictive maintenance programs use many sophisticated tools to Click to View Post help determine the health of your equipment. Did you know your finger can also help? Looseness can be detected with a vibration analyzer. When you see looseness, use your finger as a sensor and run it around the interfaces of the bearing pedestals, housings, and foundations. It is surprising how sensitive one can be to the phase difference of shaking parts that have become loose. See that it is remedied before it causes catastrophic failure. In the article, Ludeca relates a study that Toyota performed regarding premature equipment failure. 80% of all premature equipment failures are the result to three causes that could have been prevented the failure: 1. Looseness 2. Improper Lubrication 3. Contamination In addition, inadequate lubrication can be the culprit for other types of equipment failure. Often, by the time poor lubrication is detected, a considerable amount of damage has already been done. An electric motor’s winding insulation breakdown rate is doubled for every 18° F rise over 165° F. This is why motor cooling fins are actually for cooling and not for holding dust, grime, or whatever. Common sense and some basic observations go a long way in ensuring the health and longevity of your equipment.

Home Power Distribution Reliability Hydro Product Sales Repair Services About Laser Shaft Alignment: Cornerstone Laser Shaft Alignment: Cornerstone of Predictive of Predictive Maintenance Maintenance L&S Electric > Blog > Predictive Maintenance Programs > Laser Shaft Alignment: Cornerstone of Predictive Maintenance Posted on September 30, 2013 by David Manney Laser shaft alignment is a way of measuring misalignment between two or Click to View Post more shafts and is the industry standard for predictive maintenance and machinery alignment. The manufacturing industry today uses laser shaft alignment heavily because machinery alignment is a costeffective solution whenever critical functions are at risk. When a driver like an electric motor or a turbine is coupled to a pump, a generator, or any other piece of equipment, it is essential that all the shafts are accurately aligned. Any misalignment between them increases stress on the shafts and will almost certainly result in excessive wear and premature failure of the equipment. This can be exceedingly Laser Shaft Alignment Testing completed by L&S Electric costly. When your equipment is down, is profitability being sacrificed for shortsighted or outdated policies? These days, who can afford that? Typical causes of misalignment range from initial fabrication to operational vibration, overheated components, bearing issues, the high-energy usage, load imbalance and rotor bar problems. In addition, older, low-resolution, dial indicator technology cannot measure accurately enough for today’s specifications and applications. Dial technology is also subject to reading errors, ratedependent hysteresis and sticky dials. In contrast, laser alignment systems make shaft alignment faster, easier and more accurate than dial technology as they eliminate the sag and thermal changes inherent in dial indicators. In order to keep your machinery operating at the lowest cost and highest yield, you have, no doubt, implemented a routine maintenance schedule. Maintenance can be broken down into four levels: 1. 2. 3. 4. Reactive (aka run-to-failure) Basic preventive maintenance and routine inspections Combination predictive/preventive maintenance methodologies Incorporating a computer maintenance management system (CMMS) with laser shaft alignment, vibration analysis, infrared thermography, etc., and predictive and preventive maintenance methodologies Laser shaft alignment is a natural fit with CMMS because it does all the calculations and graphically prompts you through each step of the alignment process. It collects reliable information regarding the condition of a machine that might otherwise go undetected until the machine runs to failure. Researchers estimate that as much as 50% of the damage to rotating machinery directly relates to misalignment. Therefore correcting this problem is critical to production. However, these are not the only reasons. Laser shaft alignment can dramatically reduce your operating costs through: Earlier identification of problems, enabling proactive maintenance Lower overall cost of doing business through exceptional reduction in machine failures Lower labor costs as a result of fewer emergency repairs Production optimization by maximizing uptime Increased quality of production and extended useful lifecycles via significant reduction in mechanical vibration Consistently accurate, error-free measurements to 0.0001″ (2.54μ), with reports generated directly from the instrument in conformity with current ISO requirements Quantifiable energy savings In summation, laser shaft alignment is the cornerstone of predictive maintenance. Maintaining manufacturing machinery using laser shaft alignment is no longer an option; it is a must if you expect to remain competitive in today’s economy. As a matter of policy, laser shaft alignment should be an absolute necessity before your machinery is put in service. 2 Google+ 6

Home Quality Power Distribution Reliability Hydro Product Sales Repair Services Maintenance Tips to Cut Costs and not Quality About L&S Electric > Blog > Predictive Maintenance Programs > Maintenance Tips to Cut Costs and not Maintenance Tips to Cut Costs and not Quality Posted on October 28, 2013 by David Manney There are tips aplenty promising to cut your maintenance costs, but at what cost? If using This saves $100 each month, but raises the cost Click to View Post of That, is it really a savings? In the spirit of offering some really good tips that save money and not quality, Ludeca presents five tips to consider. 1: Establish a Reliability Centered Maintenance Program A well established Reliability Centered Maintenance Program helps identify correct maintenance tasks to increase the reliability of the assets and cut costs by eliminating unnecessary PM tasks. Reliability Centered Maintenance Programs assist in clarifying maintenance responsibility and prevent costly unplanned downtime. 2: Perform a Criticality Assessment of all Assets Criticality Assessments will determine which components are critical to an operations efficiency and should receive the focus. Criticality Assessments quantify safety, environmental, operation, and repair cost consequences in the event of a functional failure. Perform Criticality Assessments on your spares inventory. Do you have the correct spares and quantity of spares in stock? Do you have unnecessary spares in stock that take up warehouse space and tie up capital that could be used elsewhere? 3: Avoid Costly Repairs by Analyzing Vibration Data on a Consistent Basis Consistent analysis allows the ability to monitor trends and detect problems before catastrophic failure occurs. Consistent analysis and trending allows flexibility in scheduling maintenance and reduced maintenance costs by preventing unscheduled downtime. 4: Avoid Fixing Repeat Offenders by Completion of Root Cause Failure Analysis Root Cause Failure Analysis will determine the underlying problem causing the failure to determine the best course of action Many failures are caused by operational issues instead of equipment or maintenance issues. A minor process adjustment may increase reliability and reduce costs. 5: Ask Questions Vibration analysis and other PdM technologies can help identify a potential issue but sometimes can be difficult to understand. Do not be afraid to seek expert guidance when potential issues are identified. Have you implemented any of these tips already? If so, what savings have you measured? 7

PdM: Programs Saving Money & Headaches Home Power Distribution Reliability Hydro Product Sales Repair Services About L&S Electric > Blog > Predictive Maintenance Programs > PdM: Programs Saving Money & Headaches PdM: Programs Saving Money & Headaches Posted on October 25, 2013 by David Manney Predictive proven Maintenance methodologies evaluate predicting the (PdM) and condition optimal times of use programs in-service for corrective Click to View Post provide technologies assets to by equipment maintenance based on a direct relationship between an asset and operating conditions. PdM provides a high return on investment (ROI) by virtually eliminating catastrophic failure. When you know which equipment needs maintenance and why, PdM replaces unscheduled maintenance stops without shutting down most of the equipment, thus increasing operational uptime. If the equipment shut down is scheduled, PdM offers a quicker turnaround as well as Lockout/Tagout protocols, ensuring that machines are properly shut off and not restarted prior to the completion of service. Other advantages include: Extended equipment lifetime Lower impact on the environment Optimized spare parts handling An effective PdM program uses non-destructive testing, such as: Acoustic Emission Analysis Acoustic analysis is used for the inspection of critical air and gas conveyance components in your facility, making it possible to “hear” rotating machinery noise that are typically drowned out by ambient noise. Ultrasonic technology detects distinctive sounds caused by friction and stress waves. Changes in these waves suggest deteriorating conditions earlier than technologies such as vibration or oil analysis. With proper ultrasonic measurement and analysis, it’s possible to differentiate normal wear from abnormal wear, physical damage, imbalance, and lubrication problems. Ultrasonic detectors also catch corona and arcing of power transmission lines in daytime. Infrasonic technology measures the intensity of ultra-low frequencies generated by large, wind turbines near populated areas. Thermographic Analysis Infrared (IR) light and analysis provides the widest, non-invasive range of applications, from high to low-speed equipment and can be effective for spotting both mechanical and electrical • Continued on Next Page 8

Thermography allows you to “see” a thermal 2D or 3D image of potential problems with Click to View Post power transmission lines, electrical panels, substations, rotary equipment, and other mechanical and process related components that lead to catastrophic damage if not replaced early. Lubricant Analysis Lubricant analysis extends machine and oil life. There are two categories of lubricant analysis, Used Oil Analysis and Wear Particle Analysis: Used Oil Analysis determines the condition and quality of the lubricant and its suitability for continued use; Wear Particle Analysis determines the mechanical condition of lubricated machine components, allowing you to detect and identify the composition of solid material present and evaluate particle type, size, concentration, distribution, and morphology. Vibration Analysis Vibration analysis is most effective on high-speed rotating equipment. Vibration analysis easily diagnoses pending equipment failures as well as lubrication needs. According to ISA Automation Week, 25 years of documented savings show a 20:1 benefit-to-cost ratio for vibration analysis programs. In conclusion, the advantages of a PdM program are manifold and should be an integral part of any serious maintenance program. The US Department of Energy (DOE) estimates an 8%–12% cost savings over preventive maintenance. In fact, according to the DOE, the following average savings are typical within industrial settings: Up to 1000% ROI 70%–75% reduction in equipment breakdowns 35%–45% reduction in process downtime 25%–30% reduction in maintenance costs, including parts and labor 20%–25% increase in production 2 Google+ David Manney Follow 73 Related Posts via Taxonomies Reliability: layered like an onion (3) Predictive Maintenance: an overview (video) (3) Giving your equipment the finger.

  11. 11. Reliability: Layered like an Onion • From Previous Page With thanks and praise, we (consultants and employees) march forward with the confidence that our recommendations of tangible equipment to process manufacturers are solid and reliable in theory as well as practice. So one concern is Click to View Post assuaged on the front of reliability but what about the other concerns? Reliability of design, or more importantly the reliability of the Solution, and then thinking back to the nature of a process and thinking, again, about the definition of reliability. The challenge then becomes how do we take a process, which due to physics or nature could be inconsistent, and make it consistent? Or worse, how do we take a process input that by its nature is inconsistent, like a variable-BTU fuel, and make its inconsistent make up look and feel consistent in our control process? And once we’ve done that what have we gained and have we resolved the question of reliable? Well, isn’t this just the challenge that keeps Emerson’s Industry Consultants up at night and make their brains churn with the possibilities and pitfalls? It turns out that is quite an onion to peel! Let’s take a look at the paradigm Emerson’s Industrial Energy Consultants follow and how they started to peel the onion! First, they listen and listen a lot. One of the resounding themes they hear is that operators struggle to respond to normal variations in utility demands and that becomes even more difficult under abnormal circumstances. The abnormal circumstances they discuss are things like process trips or process variation in the form of up or downstream upsets, equipment issues, and human error due to lack of information or a deluge of information, the general stress that comes with unexpected events. Now starts the opportunity to help and begin to create order out of what seems to be chaos! So, barring a very specific complaint that would direct a consultant to a particular problem first, the team goes to the basement and starts at the beginning. I know it sounds ridiculously basic, but we all know the acronym (K.I.S.S.), Industrial Energy consultants attack in a systematic methodology; they go out, look and listen to what the equipment and process tells them. What is the condition of things? Are the critical items installed correctly and do they work? What does the air flow measurement installation look like? Is it installed correctly? Is the tubing crimped or bent? What type of airflow is it? What maintenance history does it have? We look at dampers that sometimes groan and creak at the thought of movement not exactly the picture of “reliable”. So goes the step-by-step examination of the patient. You may ask, why; why start here and not with the control system? Well, it won’t do much good to tear out the parking lot in a vehicle without wheels, why would I think reliable control is within reach if I don’t have reliable instrumentation and control elements. We know this because as a consulting group, it would frighten most of the team to quote the combined years of experience invested in looking, listening, and analyzing equipment and processes, and then revising and testing new ideas. And if it s hould be a greenfield project, we take the same lessons learned and look at P&ID‘s, instrument lists and performance specifications. How will this process unit fit into the whole picture? How does it have to contribute the surrounding process? This basic survey helps start to identify what the major “reliability” challenges are as related to equipment and gets that first layer off. In my next post, we’ll talk about where to go from here what’s in the solution that makes it special. Reliability is a broad term encompassing predictive maintenance (PdM). Taking that snapshot of your piece of equipment that provides an overview of its help is an important step towards giving you the ability to plan downtime instead of an unexpected failure. If you’re interested in learning more about how a PdM program can help you, let us know. 11
