Filtration: The Basics

An Interview with Paul Gasaway of Atico - Internormen The following are excerpts of an interview with Paul Gasaway of Atico - Internormen concerning the basics "How's" and "Why's" of Fluid Filtration. RHI - Why is Filtration Important? PG - First, it is important to understand the functions of lubricants in a hydraulic sys-tem. These functions basically include; cleaning, cooling, sealing, reducing friction and wear, and protecting against rust. If the ability of a lubricating fluid to perform these tasks is inhibited in any way, even under standard operating conditions, the result could be premature failure of system components. In short... Filtration provides a means of capturing and removing contaminants from the fluid before the tasks they are designed to do are com-promised or inhibited in any way. RHI - What causes wear on hydraulic parts ? PG - Machinery wear is primarily caused by abrasion, corrosion, and metal to metal contact. Abrasive wear occurs when solid particles enter into the areas between lubricated surfaces. Corrosive wear is generally caused by the products of oxidation of lubricants or the presence of water. Metal to Metal contact (Adhesive wear) results from the breakdown of the lubricant film. With abrasive wear, a chain reaction occurs within the system. Abrasive particles become work hardened. These work hardened particles then make contact with internal surfaces and produce MORE abraided particles. These new particles continue the cycle and become work hardened them-selves, producing more particles on an expo-nential scale. This process continues until the particles are removed with filtration, or the equipment fails. RHI - How do contaminates get into a system ? PG - Contaminates can be introduced into a hydraulic system in many ways. These Methods include: Internally generated during normal operation. Introduced with initial fluid fill. Introduced when adding makeup oil. Introduced through breathers, hatches and non-sealed reservoirs. Introduced during the manufacturing and installation of the system. Part 2 of the Atico-Internormen interview will be in the next issue of The Pipeline.

Vendor Profile: Oilgear

Oilgear Inc. started with a single hydraulic press line that was introduced soon after their founding in 1921. Since that time, Oilgear has grown to today's extensive line of hydraulic products for virtually every fluid power application, including fluid power pumps (ranging from 2 to 900 HP) and a full range of other hydraulic components. Oilgear was among the early trailblazers, entering the world arena with manufacturing facilities and sales offices on both sides of the Atlantic and Pacific, and today Oilgear provides fully-integrated manufacturing, service and training facilities in more than 50 countries world wide. Oilgears success depends upon doing things better than the competition. Better quality - Better service - More innova-tive, value-added products - all at the lowest possible cost, and in the least amount of time. Your complete satisfaction is Oilgear's primary mission, and this mission involves every Oilgear employee.

Down The Pipe

Go Figure! The process of preserving food in metal "Cans" was invented for the British Navy in 1813... Unfortunately the first practical can opener wasn't invented until 1870. In The Works. Synchronized "I"-Beam Leveler This photo shows a custom system that was manufactured for Deken Power Inc. by RHI. The system uses synchronized cylinders in place of servo-valves to automatically raise and level the I-Beams used in the construction of mobile homes.
