Magnetic Filtration Benefits and Applications

1. Magnetic Filtration Benefits and Applications Achieving optimum longevity, reliability and performance is essential to Oil filtration in industrial and automotive machinery. Lubricant cleanliness is very crucial and with numerous options, lubrication practitioners are provided for controlling and filtering contamination, including centrifugal separators, cleanable filters, disposable filters and strainers. This article reviews the many applications of Motor arc Magnets, magnetic filters and discusses the mechanism of particle separation and separators in the lubrication industry today. Here is a brief guide to products of commercial filtration. The magnet has played a prominent role in the ferrous solids from fluid streams separation. Even magnetic filtration and separation technology in the control of contamination from hydraulic fluids and in-service lubricants has found a useful niche. Currently, employing the use of magnets in various configurations and geometry there are a number of conventional and advanced products on the market. Magnetic Filters Role The importance of clean oil in achieving machine reliability is known to every car mechanics, Car owners, reliability engineers, maintenance technicians and equipment operators. In some machines as much as 90 percent of all particles suspended in the oil can be ferromagnetic (steel or iron particles), Tribologists and used oil analysts are also aware. One or both lubricated rolling or sliding surfaces will have steel or iron metallurgy typically. In piston/cylinders, rolling-element bearings, gearing, etc, these include frictional surfaces.

2. The majority of these filters incur a cost for each gram of particles removed and are disposable while it is true that conventional mechanical filters can remove particles in the same size range as magnetic filters. For using conventional filtration, there are other penalties including flow restriction caused by the fine pore-size filter media causing power or energy consumption. Causing the power needed to filter the oil to escalate, the restriction increases proportionally as pores become plugged with particles. Working of Magnetic Filters Most magnetic filters work by producing a loading zones or magnetic field that collect magnetic steel and iron particles while a large number of configurations exist. To form a magnetic field having a no uniform flux density, Magnets are geometrically arranged. When there is a strong magnetic gradient (rate of change of field strength with distance) from low to high, Particles are most effectively separated. In other words, the stronger the attracting magnetic forces the higher the magnetic gradient, acting on particles drawing them toward the loading zones. By alignment of the Magnetic Filter Rod, spacing and flux density, the strength of the magnetic gradient is determined. In these filters (see sidebar), various types of magnets can be used. As high as 28,000 gauss, Magnets used in some filters can have flux density (magnetic strength). Higher is the potential magnetic force and magnetic gradient acting on nearby steel and iron particles the higher the flux density. The following are general classifications for common magnetic products used in hydraulic fluid and lubricating oil applications while there are many configurations of magnetic separators and filters used in process industries.
