Although not new, global warming is a real and present issue right now. And whether you believe the science or not, we’re currently witnessing evidence of what climate-change scientists have been warning us about for some time: increasing incidence of extreme weather events.
This apparent trend towards wider extremes in temperature has implications for anyone who designs, operates or maintains … Read more
A recent arrival on ‘Planet Brendan’ who works for Bosch Rexoth’s ‘Large Hydraulic Drives’ division in Sweden (a.k.a. Hagglunds division) wrote me this after reading my “6 Hydraulic Mistakes….” report:
“I would have liked more information on why you shouldn’t have filters on the drain line on piston pumps. We actually use that solution in our drive units and we … Read more
If you know something about load sensing hydraulic systems, the above headline appears to be a contradiction. After all, load sensing circuits match pump flow to actuator demand. And this is supposed to increase the hydraulic system’s efficiency. Not reduce it.
HOWEVER, under certain conditions a load sensing hydraulic system can be VERY inefficient. Let me give you a real-life … Read more
