By Josh Cosford, Contributing Editor It was 20° here in Burlington, Ontario yesterday. No, not 20° Fahrenheit, but 20° Celsius … equating to something like 68° F. Nevertheless, it was warm enough to have our entire family outside playing basketball in the driveway. Because of the weather and the lack of human gatherings, I’m seeing a number of … [Read more...]
How does hydrolysis affects seals?
Literally, every fluid power system counts on soft-sealing technology to contain high-pressure liquid, allowing hydraulic energy to transmit useful work. The most common rubber technology in today’s fluid power system is synthetic, such as Buna nitrile or urethane. Each type of polymer has its advantages, but they also differ in their … [Read more...]
Hydraulic tank design is a HIT
The Hybrid Integrated Tank offers a cost-effective upgrade for mobile hydraulic systems. Hydraulic tank systems for mobile equipment must be crafted to handle diverse and multifaceted requirements. OEMs often take a do-it-yourself approach: purchase individual components such as tanks, filters, connectors, breathers and oil level indicators, … [Read more...]
Varnish removal and prevention system
Des-Case has launched a new varnish removal and prevention system. Varnish is a common problem for a wide range of hydraulic fluids and lubricants, especially in turbine and plastic injection molding applications. Compatible fluids include mineral oil, synthetic ester, and phosphate esters. It results in: valves sticking shorter fluid … [Read more...]
A review of hydraulic fluids and contamination control
It’s critical for equipment manufacturers and the engineers they employ to possess a sound understanding of the composition of oils, the properties of lubricants, and how hydraulic fluids can impact machine performance. With that fact in mind, IFPE 2020 will offer attendees an education session entitled “Hydraulic Fluid Properties, Efficiency … [Read more...]
How do water hydraulics work?
By Josh Cosford, Contributing Editor Most of you are familiar with the use of oil as the fluid medium for hydraulic systems, which is inherently excellent at its job. It lubricates well, provides good heat capacity and is stable over various pressure and temperature ranges. As good as oil is, it’s not the only power transmission liquid in use … [Read more...]
Online app calculates hydraulic oil viscosity at different pressures
Webtec has launched a new on-line hydraulic oil viscosity calculator app which calculates the viscosity of hydraulic oil at different pressures. Hydraulic fluid suppliers provide oils with different viscosities. These oils are most-often badged in terms of their ISO number or grade, where common grades for hydraulic circuits include ISO 32, 46 … [Read more...]
Freudenberg upgrades quality process with new vision inspection units
Freudenberg’s inline spring inspection machine, a packaging marvel no bigger than a standard microwave oven, scrutinizes 6-12 mm diameter garter springs at a rate of four per second for defects including kinks, gaps, irregular diameters and poorly joined ends. The machine segregates defective components out of a typical batch of 10,000 springs and … [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...]
Purity FG Synthetic Fluid 46 designed for food-grade applications
While exhibiting at Reliable Plant in Cleveland a few weeks ago, Petro-Canada Lubricants Inc. highlighted unique hydraulic fluids designed to give users peace of mind in tough environments. The company's Purity FG Synthetic Fluid 46 was awarded Husky Approval last year, for use in Husky injection molding systems, particularly in food-grade … [Read more...]
