What do miners, lumber jacks and bull dozer operators all have in common? Besides choosing dangerous heavy duty jobs as occupations, they all work with some pretty powerful and extreme machinery everyday. Their equipment, along with trenchers, marine winches, cranes and car crushers, use intense amounts of power to do their job. But where does energy powerful enough to flatten cars or move massive amounts of earth come from? The answer is hydraulic motors-components of hydrostatic power transmission systems that convert hydraulic energy into mechanical energy. These motors are able to harness the immense power generated from fluid pressure and supply energy to the most massive and extreme machines.
The full range of today’s hydraulic presses is some of the most powerful and versatile manufacturing equipment. Achieving the highest compressive force of all the power presses, these machines are crucial for the forming and molding of a wide spectrum of materials: metals, plastics and composites, rubber, wood, and laminates. From deep drawing essential parts, such as tanks and fenders, for the production of motorcycles to creating 2,640 plastic credit cards per hour, the manufacturing realm would be lost without hydraulic presses. The scrap metal processing industry also relies on shear hydraulic press force to smash discarded cars and such into compact, manageable squares of reusable material for pop cans, paper clips, etc.
The current types of water filtration systems dominating the market today-multimedia, screen or fixed barrier, disposable and membrane filters-may soon have a tough competitor. Undergoing testing at the US EPA in Cincinnati and the University of Alberta, R3F, or radial flow fluidized filter technology, is yielding very positive results. R3F filters could soon be available to manufacturers for the municipal, industrial and agricultural sectors of filtration systems. This filtration equipment uses both radial flow cartridge and non bonded media in the form of small, spherical glass beads. It is similar to microfiltration technology, but has significant cost and operational benefits. University of Alberta testing found that as they used smaller and smaller media (glass beads), the percentage of small particles were separated from the filtered water, a benefit known as selective removal, which is used to remove cysts and pathogens. The glass beads are as efficient as using sand, but more cost effective.
Manufacturing practices are becoming increasingly more scrutinized for their effect on the environment. Real changes are underway in the area of emissions, byproducts, packaging materials, fluid selection, and power consumption – to name only a few. While environmental payback may be the goal, many of these initiatives encounter obstacles, not the least of which is additional operational costs. Not so with lubrication – the greener the better. Utilizing very small amounts of lubricant at controlled intervals is productive for a number of reasons…
