During a recent conversation I had with a member who builds hydraulic power units, this observation was made: “Oil coolers are generally resisted by customers because of initial cost and maintenance, so fitting a bigger reservoir, when possible, is often the preferred solution.”
I recall coming across the very same resistance when I was building hydraulic power units for end-user … Read more
I recently came across an article describing a failure that occurred on a hydraulic machine during the last northern winter. The extreme cold had caused the water present in the hydraulic oil to freeze on the surface of the installed suction strainer. When the hydraulic system was started the ice-clogged suction strainer imploded and the resulting debris destroyed the hydraulic … Read more
A hydraulic machine has lots of moving parts to maintain. In fact, a hydraulic system is one of the most complex systems to maintain effectively. And here’s one more item to add to the list: the machine’s drawings. A machine’s hydraulic (and electrical) schematic diagrams don’t wear out, but they do tend to become inaccurate over time.
Even absent a … Read more
