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...] about Early warning system heads off downtime
Contamination Control
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...] about How do you remove water from your hydraulic system?
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...] about Particle monitor for real-time analysis
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...] about How does heat affect a hydraulic system?
Miniature in-line screens and breathers from O’Keefe Controls advance particulate control
O’Keefe Controls Co.'s miniature in-line screens/breathers help engineers protect critical components from damage or reduced performance due to clogging or reduced flow rates. Designed to augment the protection of critical components in fluid control systems, the fine screens are intended to prevent the occasional particles that enter the fluid … [Read more...] about Miniature in-line screens and breathers from O’Keefe Controls advance particulate control
What is the “toast” test?
An important characteristic of many hydraulic fluids is the ability to maintain performance at high temperatures. Higher temperatures can cause oxidation—the reaction of the fluid and its constituents with oxygen. The rate of reaction accelerates as temperature increases, as does the presence of catalyst metals like copper and iron, especially at … [Read more...] about What is the “toast” test?
What does hydraulic maintenance mean to you?
By Josh Cosford, Contributing Editor I once had a walk-in customer bring with him an old, rusty spin-on filter, which I believe was originally coloured white below the now orange and brown soup of rust and oil. He needed a replacement filter for his vacuum truck, a machine he said he bought used eight years ago. I grabbed a stock filter head to … [Read more...] about What does hydraulic maintenance mean to you?
Track contamination, not people
Nobody likes a micromanager. A boss constantly looking over your shoulder is at best annoying and more often counterproductive, demotivating and the root cause of high turnover. Yet in recent head-scratching news, Amazon has patented a tracking wristband that monitors a worker’s every move and vibrates when they do something wrong. Ostensibly, … [Read more...] about Track contamination, not people
Contamination begets contamination
By Josh Cosford What I’m about to tell you could be the most profound concept of hydraulic fluid contamination control. Without this understanding, you and your hydraulic system will be forever plagued by contamination-related failure and decay. It’s obvious a hydraulic system requires contamination control, but less obvious how far you … [Read more...] about Contamination begets contamination
Proper hydraulic contamination control
(Following is the unedited transcript from a recent webinar, with Josh Cosford as the presenter.) We're going to talk about proper contamination control today, and what that means to your hydraulic system, how you can apply it, and what it all means in the end. Controlling contamination is the single most important consideration for ensuring … [Read more...] about Proper hydraulic contamination control
