Battery powered vehicles have been with us for many years and acknowledged as the workhorses for the milk delivery industry, as golfing buggies and in many other niche or specialist applications.Latterly the impact of two major drivers has focused greater attention on the acceptability and benefits of electric vehicles, thrusting them once more into the headlines; these being the rocketing price of hydrocarbons and city pollution.

 One leading edge UK manufacturing company, Zytek, saw the need for electric vehicles in 1994 when Co-founder Bill Gibson, a long-time exponent of light-weight, very high performance electric vehicles, began the development of what was to become the highest power/density ratio, electric vehicle drivetrain to date.

 

Why Monitor?
The concept of Predictive Maintenance has now become accepted practice, world wide.

Locating, defining and acting on potential problems before they become catastrophic is the main objective of a predictive maintenance programme. Techniques include thermography, vibration analysis and motor monitoring. Routine monitoring is not only the most effective method of determining an early diagnosis, but has many other positive aspects.

Michell Instruments has re-launched its Coreci and Rense ranges of relative humidity instruments and sensors under the Michell Instruments brand. A new catalogue containing the complete range, as well as dew point transmitters and calibration instruments, is now available.

Michell acquired the Coreci RH division in 2008, adding their range of innovative RH instruments and sensors to those of the Dutch company, Rense Instruments, which Michell bought in 2006.

It was in 1816 that the Revd. Robert Stirling propounded the idea of a heat engine which he termed an ‘Economiser’ now universally known as a ‘Stirling Engine’. The operational concept is that it acted as a heat exchanger, retaining heat from the hot portion of the engine as air passed to the cold side, and released heat to the cooled air as it returned to the hot side and in the process converting energy to mechanical work, with near perfect efficiency.

Stirling engines were widely developed in the 19C until the advent of the electric motor superseded it. Modern versions of the engine are in existence, having been used for specialist civil and military applications. But the need for the development of alternative power sources and the availability of modern technology and materials have resulted in renewed interest and exciting developments in this area.

Bombardier Transportation has its global headquarters in Berlin, Germany with a presence in over 60 countries. It has an installed base of over 100,000 vehicles worldwide.

The Group offers the broadest product portfolio and is recognized as the leader in the global rail sector.Within the UK Bombardier has established a world class engineering maintenance and repair site based at Crewe, the historic railway engineering town established by the Midland Railway in 1839.

More and more often, industrial applications expect mobility and flexibility from compressed-air processing. For example for the employment at different sites or outdoors. A solution to that is the installation of complete compressed-air stations in transportable sea containers. These mobile performance centres make special demands on the technology applied, in particular as far as compressed-air drying is concerned.

A company which recognised the growing need for mobile compressed-air stations particularly early is Karl Uhl GmbH in Bochum, Germany. For 80 years now already, the experts from the Ruhr area have operated as wholesalers and service providers of compressed-air technology.

In practice noise date are not always consistent. Noise at machines can stem from unknown sources. It is important to know what noise levels can be found in the system and what causes them. PRUFTECHNIK Condition Monitoring performs acceptance measurements of noise emissions and compares the results with the latest standards. If necessary, suitable measures for noise reduction are identified and recommended. Measurements are made with the data analyzer VIBXPERT and evaluated with DBSpectra and the software OMNITREND. Dominant noise sources can be identified using third octave or narrow band spectra.
 

“Achievable noise reductions, e.g. in gear drives, can be up to 5 dB: through measures on housings, up to 7 dB: through measures on rotors, toothing and housings and up to 10 dB: through secondary noise shields or enclosures” says Dr. Edwin Becker, Manager Service and Diagnostic Center.

Entry-level data collector

VIBROTIP is an extremely rugged and easy-to-use
hand-held data collector for five key indicators of machine condition. All sensors are built in, with no cumbersome cables or fragile plugs.

VIBCODE (optional) can be used to eliminate mixups of measurement location and type, and OMNITREND PC software automatically archives trend data, issues warnings and alarms and programs VIBROTIP with all desired measurements.

Intrinsically safe data collector

For monitoring and diagnosing machine conditions in the chemical industry, in refineries, in the oil and gas industry and in any other potentially explosive environment that requires intrinsically safe measuring systems.

 

Technical Specifications

The DC 1800 EX is suitable for general cleaning and source extraction. The DC 1800 is small and lightweight, therefore suitable for those that need a highly portable machine that still is powerful enough for source extraction. With its low weight it is easy to carry onto the job site and it can be easily stored or rolled under a workbench.

The DC 1800 is equipped with a steel container and a plastic bag can be used inside the container. It is equipped with a brushless motor (for spark-free operation) and is certified to IP5X standard.
