At Fluid Power World’s recent Fluid Power Technology Conference in Cleveland, Tom Wanke of the Milwaukee School of Engineering discussed the importance of contamination control in hydraulic systems. One focus was on gaseous contamination. Here are some highlights of his presentation. We can break physical contaminants in a hydraulic system … [Read more...]
White paper looks at contamination control
In every industrial market, from ag and mining to pulp and paper and power generation, contamination is an issue. LubriSource, Dayton, Ohio, has published a white paper, “Water & Particulate Contamination in Oil & Lubricated Systems” that delves into the problem and offers numerous solutions. It’s authored by Tony Arenas of Y2K Fluid Power, … [Read more...]
More desiccant and increased airflow means longer life for breathers
Des-Case has recently improved its breather designs, featuring more desiccant and increased airflow without increasing the external dimensions of the breather, which adds up to 25-50% longer breather life. Now its VentGuard, Standard and HydroGuard breathers feature the new options, including: Domed cap to allow for better washdown … [Read more...]
Trelleborg opens new production line at its Swedish brake shim facility
On November 26, the Trelleborg Sealing Solutions facility in Kalmar, Sweden, inaugurated a new production line that will increase brake shim capacity at the facility significantly. The line includes triple stations of adhesive lamination and a vision system with marking robots to ensure flexibility in manufacturing and enhanced quality control, … [Read more...]
Adsorber filters protect against harmful condensation
Water in the oil is a serious issue for many hydraulic systems, because it can lead to increased wear and leakage. Adsorber filters which prevent moisture ingress via the tank breather system provide a remedy, according to engineers at HANSA-FLEX, Bremen, Germany. Unfortunately, although these filters can prevent serious damage and high … [Read more...]
Hydraulic plugs provide positive seal to prevent contamination, leakage
Polymer Molding’s new hydraulic plugs are designed to provide a positive seal for SAE straight thread o-ring ports and MIL-MS-33649 bosses. The FFP Series threaded plugs are knurled to protect against contaminants and for easy assembly and removal on fluid power components. An integrated O-ring type bead seals in the bevel of the port to prevent … [Read more...]
Early warning system heads off downtime
Unit Fluid Monitoring (UFM) systems permit in-depth monitoring of hydraulic power packs and lubrication systems, according to officials at Hainzl, a manufacturer of hydraulic, automation and robotic products based in Linz, Austria. The main focus is on analyzing the oil for signs of humidity, aging and degree of contamination, as well as monitoring … [Read more...]
How do you remove water from your hydraulic system?
It’s common knowledge that particulate contamination is unwanted in hydraulic systems. Contamination in hydraulic oil can damage mobile and industrial machinery. Of as much concern should be water in oil, as it too can lead to component failure. Water in hydraulic fluid can be seen as free, dissolved or emulsified and can reduce hydraulic … [Read more...]
Particle monitor for real-time analysis
The redesigned Stauff LPM-II-plus particle monitor is an optical particle counter with high-performance LEDs that automatically detects the degree of contamination of hydraulic fluids and determines particle sizes in compliance with ISO 4406, NAS 1638, AS 4059E and ISO 11218 standards. It is for continuous measurement or analysis in … [Read more...]
How does heat affect a hydraulic system?
Everyone knows that contamination can be catastrophic to a hydraulic system. But heat can also be detrimental to hydraulic fluid and the components within that system. Heat contamination reduces oil viscosity, which in turn reduces the fluid’s ability to lubricate components. This thinning of the oil causes surface-on-surface wear. Without … [Read more...]
