New guarding standard EN ISO 14120 tightens requirements
Following final approval by the European Commission, from September 2014, EN ISO 14120 (Safety of machinery - Guards - General requirements for the design and construction of fixed and movable guards) will replace EN 953.
Internet machine servicing, servitization and Industry 4.0
By adopting Industry 4.0 technologies as an enabler for servitization (also referred to as servitisation), machine builders and process equipment suppliers can maximise their revenues by offering new value-added services that improve their customers' performance, says John Pritchard, Managing Director at MAC Solutions.
Intelligent design of new generation IP68 enclosures
When talking about enclosure quality, IP68 certification is the Holy Grail. IP68 enclosures are able to protect against water ingress even when fully submerged, making them suitable for applications in harsh environments. In order to guarantee the water resistance, most manufacturers resort to cumbersome, double housing or gel-filled designs. While these can be quite bulky and time consuming to install, the inconvenience is generally accepted as a necessary hassle to achieve the required protection. But is that still the case? Alan Lewis, Business Development Manager for Retex UK, explains how thoughtful design is leading to a new generation of IP68 enclosures which offer end-users greater flexibility of choice and reduced installation times.
Specification advise for cable glands and enclosure accessories
Cable gland design has become increasingly varied as manufacturers begin to realise that they need to offer their customers a distinct advantage in order to hold on to their market share. With all this variation it can be hard to find the cable gland that is right for your application. Hylec-APL provides a range of mainstream and specialist options which offer end-users and OEMs the flexibility to choose the right option for their application.
Sizing of pipework for steam applications for reliable operation
Steam is used in a wide range of industries for a variety of processes, from a basic small heating circuit to large scale hygienic steam production, involving specialist equipment which needs to be designed and maintained properly to ensure efficient and reliable operation of the process equipment. Ian Webster, Hygienic Processing Segment Manager at Bürkert UK offers steam training courses; here he looks at some of the basic calculations that should be understood by design and maintenance engineers in order to achieve a safe and efficient process.
High-pressure, high-volume pump design for harsh environments
Pump designs fall mainly into two categories – centrifugal and reciprocating (piston) type – each with its own benefits and constraints. Mike Sherman, Marketing Manager at RMI Pressure Systems, looks at the design criteria and some of the applications.
When two-speed motors are the best option
Two-speed motors are an often-overlooked technology, but they can be a good choice of prime mover when robustness, simplicity and low cost are required, alongside operational flexibility. Jerry Hodek of Wellingborough-based industrial motor specialists, Rotor UK, explains where they fit into the spectrum of drives.
Metal vs. plastic: specification of large outdoor enclosures
Large, outdoor enclosures are a necessary aspect of the general infrastructure of day-to-day life. Used to house vital control panels and electrical connections, these enclosures must be able to withstand all that is thrown at them to protect their contents; this includes extreme temperatures, rain, UV exposure and even vandalism attempts. Due to its inherent strength, steel has traditionally been the material of choice despite several shortcomings; but can glass-reinforced polyester (GRP) offer a robust alternative which offers protection where steel cannot?
