08/11/2011 - Security Summit in London highlights the importance for IT and Automation collaboration to mitigate cyber risks to critical infrastructure
Rockwell Automation and Cisco Systems use strategic alliance to show how vigilance and unity across IT and Engineering can help protect critical infrastructure, such as that owned by Severn Trent Water, from potential security threats
02/11/2011 - Total Cost of Ownership: A Crucial Consideration
In the oil and gas sector, where costs and profitability are major concerns, it might be expected that lowest total cost of ownership (TCO) would be one of the most important factors to be considered when procuring new equipment. Unfortunately, many of the procurement procedures in use today favour equipment with the lowest up-front capital cost over equipment with the lowest TCO.
27/10/2011 - Choosing the Right Flowmeter from the Dozens of Types Available is Difficult...Paul Trevitt of Burkert UK provides a few insights.
There are so many different flow measurement solutions on the market today that discussing all the possible options is an impossible task. However, as with all technologies, some designs of flowmeter are more widely used than others. In this article we look at five of the most popular units, discuss their advantages and disadvantages and highlight their major areas of application.
With the Water Framework Directive (WFD) and the AMP (Asset Management Plan) 5 spending round now firmly on the agenda, there is increasing pressure on wastewater treatment works to improve efficiency and implement life cycle costing strategies. Simon Lambert, Sales and Marketing Director at Mono, explains how progressing cavity (PC) pump technology is evolving to help facilities meet the demands of modern wastewater treatment.
Determining that electric motors are properly loaded enables users to make informed decisions about when to replace them; and decisions about which replacements to choose. Measuring motor loads is relatively quick and easy with the right equipment, and every company with a significant motor stock should be looking to perform a motor load and efficiency analysis as part of their preventative maintenance and energy conservation programmes.
Engineers are always under pressure to reduce costs, improve quality and optimise plant utilisation, but as the saying goes, if you can’t measure it, you can’t control it. Stuart Hannah of HMS Industrial Networks explains how the use of cloud computing and the Internet make remote management of your plant and assets a much simpler and more attractive proposition than in the past.
07/09/2011 - Identifying and correcting the causes of bearing failure
Identifying and analysing the root cause of a bearing failure is critical in order to prevent similar failures from occurring again. Brian Williams, Quality Director at The Barden Corporation, urges companies to introduce a regime that enables the symptoms of bearing damage to be recognised early, as well as putting a systematic procedure in place for securing damaged bearings.
18/07/2011 - Don’t Jump to Conclusions over Drive Efficiency
Fitting variable speed drives to motors is often put forward as a way of saving energy, and this idea appears to have influenced the wording of part of the European Ecodesign Directive. However, as Phil George of Eaton’s Electrical Sector explains, variable speed drives are not always the most energy efficient choice.
17/06/2011 - Substantial savings to be made with revolutionary bearings
Phil Burge, Communication Manager for SKF, explores the options of motor replacement and repair looking in detail at the latest bearing technology that is enabling considerable energy savings to be realised.
25/05/2011 - The next big thing?
35 years ago the salesperson selling compressed air generation and treatment equipment had very few tools at his disposal. Many systems were oversized because there was no low cost means of deciding the size of the system so educated guesswork was the order of the day. The only scientific way to determine component sizes was to note all equipment consuming compressed air and then observe the cycles or take a usage factor ie if using a drill it is unlikely that the drill would be in constant use as the hole would normally be drilled to insert a screw or bolt. Even doing this usually led to a calculation which would oversize a system because the biggest sin would be to not have a system with adequate capacity. Air quality was poor relative to today. Filter manufacturers were still focussing on sterile air and process filters rather than the new kid on the block-compressed air. Dryer manufacturers were making fridge dryers with no great attention to power consumption or pressure drop and desiccant dryers were selected on capital cost rather than running costs resulting in more “heatless” dryers purchased but wasting up to 20% of compressed air through purge loss.
