Situation

One of sixteen new 25kW 2-pole motors had an insulation failure just a couple months after being installed. The motor application is line-operated, direct across the line-started fans.
A closer look at the failed motor showed that the root cause of the insulation failure was mechanical. Parts of the failing drive-end bearing were flung into the end-turns of the windings, causing a phase-phase short circuit, as seen in Fig. 1.

Schaeffler UK has released its new technical training course programme for 2013. Courses offered include one, two and three-day training for managers, engineers and technicians involved in the selection, operation and maintenance of rolling bearings, as well as condition monitoring, vibration analysis and mounting of rolling bearings.

SATIR G96 – The Feature Rich HD Thermography Camera that's just bursting with features; applications for the G96 include electrical inspection, mechanical systems, building structures, medical, equine, electronic inspection, scientific and non-destructive testing thermography.

With the acquisition of their new Webster Bennett vertical borer, machining capacity has been greatly increased at Rewinds and J Windsor. The machine, probably the largest in the North West, offers machining capability for parts of up to 3m in diameter, 1.5m height and up to 40 tonne weight.

ETher NDE, a UK-based manufacturer of Eddy Current products, is pleased to introduce the VEESCAN ET Wheel Inspection System. The VEESCAN is EThers' first Wheel Inspection System and is available in two different models, VEESCAN H for maximum flexibility and VEESCAN R for optimised productivity. The VEESCAN has a proven mechanical design and established record of breakdown-free operation for 365 days or more. Appealing to many companies in the Aerospace industry and with the choice of two, fully featured options, the VEESCAN is ideal in all aircraft wheel-testing environments.

The Problem:
A former refinery site in Illinois is currently in the process of reclaiming the polluted land on which it sits. A major component to the reclamation of this brownfield site is the pumping of groundwater underneath the former refinery. The water is then treated to remove the contaminants. This also lowers the water table underneath the refinery, forcing surrounding groundwater to flow into the low spot. With this system in place, the contamination will not spread throughout the surrounding water table, which is primarily under residential areas.
The carbon steel piping that carries the contaminated groundwater to the treatment facility is critical to the process. Any unplanned down time caused by a piping failure could potentially cause the water table to rise and spread the contaminants to residential groundwater. With these conditions in place, inspection is vital to ensure that the piping is in good working condition, as well as to have contingencies in place for scheduled repairs.

Supported by some of the Country's leading companies, this one day seminar will explore the background to OAC and the real life experience of senior production and manufacturing directors in its implementation.

Operator Asset Careis based on the principle that the people operating production equipment on a daily basis are the ones most capable of improving equipment reliability and performance.
OAC creates a culture where operators develop 'ownership' of their equipment and work with maintenance, engineering and management to ensure that equipment operates properly every day. The day will be conducted by MCP consultants in partnership with industry colleagues who have overseen and managed programmes within their own organisations.

Our Omniscans are the ideal solution for flange face corrosion inspections utilizing phased array techniques. Depending on the inspection requirements, Oceanscan can provide either an Omniscan 1664 for simple image capture reporting or an Omniscan 16128 for full encoded data capture analysis. Oceanscan has the technology.

Three tried and tested probe positions are on the flange tapper, between the bolt holes and on the outer rim, illustrated below. The shear wave inspection is usually carried out from 35 to 70 degree when fitted with a 55 degree wedge; data is displayed in S-Scan.
