Maximising production efficiencies in food and beverage processing plants

By selecting, maintaining and monitoring critical components and inside rotating plant and machines such as gearboxes, electric motors, pumps and fans, food and beverage processing companies can improve their plant efficiencies, eliminate production downtime and increase the operating life and reliability of plant equipment, says Dr Steve Lacey, Engineering Manager at Schaeffler UK. In food and beverage processing, production is typically based on highly automated, fast moving processes and systems, where every second of production counts. In these operating environments, the cost of production downtime can equate to hundreds of thousands of pounds per day. Total maintenance costs for a typical food or beverage manufacturer are around 15-20% of total costs. Although maintenance departments are set up to deal with problems like these, often, because of time and resource constraints, maintenance becomes reactive, with problems around the plant dealt with as they occur rather than in a proactive, planned manner. Condition monitoring (CM) prevents the unnecessary replacement of components and the subsequent introduction of possible new and unrelated problems. Maintenance teams can benefit from the use of CM technology to predict when failures are likely to occur and plan replacement during production shutdowns. In too many companies, components are replaced on a time basis rather than on a condition basis because this is considered to be the safest option. However, there are numerous technology safeguards available which, when compared to the cost of lost production, are relatively inexpensive. These safeguards use the latest CM technologies and predictive maintenance systems, including vibration monitoring, wear monitoring and automatic lubrication to protect plant and machines. Intelligent monitoring FAG SmartCheck is an extremely...

WEG’s new synchronous motors are tough and dynamic

WEG, a leading global manufacturer of drive technology, has introduced a new series of robust and efficient synchronous motors, the SM40 series, for the power range from 5 to 35 MW. The motors provide exceptional reliability in demanding applications with extended maintenance intervals, enabling users to reduce servicing costs and increase process uptime.With shaft and rotor made from a single piece of forged steel and high starting torque, the new SM40 is ideal for high-inertia applications including centrifugal compressors in air separation plants or the oil and gas industry, large fans in the steel industry or power plants, and high-power pumps and pulp mills. The SM40 motor has a robust rotor construction with high mechanical strength and stability, and has been designed to eliminate the risk of detachment of individual pole shoes or pole mounting screws. The stator consists of high-quality, low-loss silicon steel laminations and top-grade bobbin windings insulated using a special vacuum/pressure impregnation (VPI) process while an optimised thermal design ensures uniform temperature distribution along the stator, prolonging the service life of the winding insulation.   The motors have a high starting torque and low starting current enabling users to achieve significant energy savings, which is particularly important in energy-intensive applications. The low starting current also minimises the impact of the motor on the power supply network and means starting aids such as starting chokes, autotransformers or variable speed drives become unnecessary, thus bringing costs down further. M40 motors can also help plants reduce power costs and improve the efficiency of the power network to which they are connected because the deliver high efficiency over a wide...

How efficient are your motors… really?

How efficient are your motors… really?

Around the world, legislation relating to electric motor efficiency is tightening in an attempt to reduce carbon emissions and damage to the environment. However, far less attention is paid to some of the practicalities. Here, Lucie Hodkova of Exico looks at how best to determine the efficiency of an installed motor. Motors are the greatest consumers of electricity in the world, with about 70% of all power generated being used by them. Since the Rio Earth Summit a generation ago, there has been a continuous effort to improve motor efficiency, with much effort being put into drafting efficiency standards and new testing methods for newly manufactured motors, which get gradually tighter over the years. However, this approach misses the point that there is a huge number of motors already in use around the world and their efficiency does not come under anything like so much scrutiny. So, a review of the motors in your place of work may well lead to the identification of significant improvements to your energy efficiency, carbon footprint and – perhaps most importantly – saving on your utilities bill. If you use machine tools, automated manufacturing systems, conveyors, or other ‘technical’ equipment, each of these is likely to use a number of motors. If you have air-conditioned offices, there will be motors driving pumps and fans. Medical equipment, displays, test stands, lifts, escalators, extractor fans in kitchens and laboratories are all motor-driven and, typically, their efficiency may never have been checked! All motors should have their efficiency checked and it may be best to start with those motors that are used a lot; if a...
