Agriculture electrifies without bailing on hydraulics
Efficient farming is top of mind for the agricultural industry, but not at the environment’s expense. Though net-zero targets tend to push OEMs toward fully electric and even autonomous machines, there are ways to partially electrify without overhauling a design. HAWE Hydraulik provides examples of how to increase efficiency by electrifying functions strategically. Electrify work […]
How do I know I’ve oversized my pump?
By Josh Cosford, Contributing Editor Oversizing your hydraulic pump is a relatively common error by beginner fluid power professionals or, more likely, entirely untrained individuals tasked with maintaining machinery. Everyone wears many hats these days, so don’t take it personally if you’ve inherited a role that requires skills above your pay grade. More than once […]
How do you know when to replace your hydraulic pump?
By Josh Cosford, Contributing Editor Hydraulic pumps are a fundamental component in hydraulic machinery and they play a pivotal role in ensuring everything runs with the force and reliability you expect from hydraulics. Over time, though, pumps might show signs of wear and tear, just like any other piece of equipment. And just like most…
Energy management system for electrohydrostatic actuation systems
Moog Inc. announced a new Energy Management System (EMS) for machines with electrohydrostatic actuation systems. In the machine manufacturing industry, more and more drive systems are being converted from the servo-hydraulic throttle principle to electrohydrostatic actuation systems (EAS). The 4-quadrant capability of the electrohydrostatic pump unit and servo drive used in this technology, in combination…
Try this trick to avoid buying a pressure compensated pump
Hydraulic piston pumps are the current standard for power, control and efficiency, but such a position in the hierarchy comes with more significant investment and responsibility. Piston pumps are expensive, complicated and involved compared to their lessor counterparts, such as the venerable gear pump. Inexpensive piston pumps still start in the four-figure range, and once…
