When it comes to detecting and analysing machine wear, testing for ferrous density – the presence of iron or steel particles in an oil sample – is especially important.
Particle density analysis should be routinely carried out on the wear mechanisms responsible for the largest amounts of ferrous particles.
Of the principal wear metals, iron is by some way the most significant for monitoring purposes. This contaminant tends to accumulate in dynamic clearances and so cause a chain reaction of wear. Closed loop systems – hydraulics and pumps for example – are particularly prone to this. Traditional barrier protection alone will not provide adequate protection from debris, and it only takes a small amount of contaminant to start damaging the system over an extended period of time.
A Continuous Monitoring programme will make use of ferrous density testing, among other techniques, to ensure equipment is being lubricated properly without needing to shut down the machine and suspend production.
Analyse wear debris
Parker Kittiwake supplies a range of instruments which analyse wear debris to determine the origin, wear mechanism and contamination levels, thereby allowing engineers to identify the worn parts of a machine before severe damage occurs.
ANALEX fdMplus Ferrous Debris Monitor
This robust magnetometer measures wear metal particle contamination in oil and grease samples, with results displayed in industry-standard parts per million (PPM) values. It can test and analyse samples in the field as well as in the laboratory, making it especially suitable for remote, unmanned locations such as wind turbine farms where a full laboratory analysis is not possible.
Whether employed at power plants, mines or railways, by measuring debris in all types of oil ANALEX instruments are making production more efficient and operations more profitable.
The Ferrous Wear Meter (FWM)
This simple-to-use instrument offers all the usual Parker Kittiwake quality and accuracy, but has been designed for clients who do not need an instrument as sophisticated as the fdMplus. It can test samples on-board, including in remote locations, and provides a direct reading in PPM on its LCD screen. Featuring a magnetometer adapted for on-site use, FWM testing is performed by placing a 5ml test tube containing the sample directly in the instrument’s aperture. The sample’s metallic content appears on the screen in less than two seconds. No time needs to be spent preparing the sample.
In a competitive marketplace, it is highly advantageous to minimise downtime and so keep costs down. By ensuring lubricants and components are free of contaminants operators can improve the overall reliability of their equipment.
Parker Kittiwake has over two decades’ experience in fluid condition monitoring equipment for fuel, oils and water, and provides a comprehensive range of test kits and on-site analysis solutions for marine, offshore and other applications.
