A Powerful Ally for Gearbox Protection: Power Plant Edition - Special Magnet Filter -
Magnet Filter MAGNOM (Magnum)
Achievements developed in the harsh environment of F1 racing. Please take a look at the field report on the gearbox of the coal pulverizer operating in a thermal power plant.
"Magnum" was originally developed to improve the durability of transmissions in the harsh environment of F1 racing. It was later proven to make a significant contribution to the protection of large gearboxes used for pulverizing coal, which is the fuel for coal-fired power plants. Amid calls for the abolition of coal-fired power plants in pursuit of a decarbonized society, these plants continue to operate as electricity consumption expands worldwide. Naturally, unexpected system failures can lead to significant losses. The reasons why conventional barrier-type filters are ineffective, which led to the introduction of "Magnum," include the following: - They create pressure loss. - The viscosity index of the lubricating oil used is high. - They inadequately remove tiny iron-based particles that can damage the system. In any system, it is essential to quickly remove the increasing contamination to prevent a chain of wear. Since the installation of "Magnum" at the Didcot A power plant 18 months ago, it has been reported that the issues with the pulverizing mill gearbox, which occurred about four times a year previously, have become nonexistent. The earlier "Magnum" is installed, the more effective the protection of the mill, which means reduced losses!

basic information
■Removal of fine particles is possible The Magnum can capture fine magnetic particles (submicron: 10μm to 0.07μm) that cannot be removed by filters using filter paper or mesh, such as cartridge filters. ■No clogging Due to its special structure, which sandwiches the magnet between special plates, it does not block the flow path in the area where iron powder is captured. Therefore, it does not cause any clogging or pressure loss. Even when the capture capacity limit is reached, it does not hinder the operation of the device. ■Powerful capturing ability The magnet enhances the magnetic flux through a special arrangement, resulting in a significant difference in the capturing ability of iron powder compared to simple magnets. Unlike conventional magnetic filters, which can only capture contaminants from liquids close to the magnet, this structure greatly improves the cleanliness of the fluid. ■No re-release Captured contaminants are stored in a powerful accumulation area separate from the flow path. The dangerous phenomenon that can occur with regular magnetic filters, where the magnetic force weakens as one moves away from the magnet, causing once-captured and solidified contaminants to re-release as a lump, does not occur at all.

Magnets have been used for a long time. However, a standalone magnet has a limited range of magnetic force, and trying to improve efficiency leads to new problems such as clogging and reflow. To overcome these issues, Magnum was developed. It is a groundbreaking magnet filter core technology that leverages the advantages of conventional filters while overcoming their disadvantages. By installing it within a circuit, it efficiently removes fine wear particles without causing clogging or reflow. Its performance is recognized worldwide, maintaining the performance of aircraft, racing vehicles, and various hydraulic and lubrication equipment.

Historically, OEMs and end users of hydraulic systems have recognized the issue of iron and have attempted to address it using some form of magnetic device. For example, consider a simple magnet-type drain plug. After regular equipment repairs or system failures, when the magnetic drain plug is removed, there is always a state where iron contamination is "attached" to the magnet. Dirt adheres to the surface of the magnet. Magnetic energy decreases in strength as the distance increases, following the inverse cube law (the inverse square law of distance). This means that unless you are close to the magnetic field lines, it is clear that contaminants cannot be adsorbed or removed. In other words, the more particles come into contact with the magnet, the further they move away from the magnet (or energy source), and as the contaminants move away from the energy source, they ultimately get washed away. Because the particles were exposed to the magnetic field, they remain as weakly magnetized clumps. When parts concentrated with high carbon steel are the first to arrive, it is natural that they often experience catastrophic failures.
