The History and Development of Hydraulic Machines
April 12th, 2017Fluid power has come a long way. It began with the end of the hunter-gatherer era, an age when early man used primitive water irrigation networks to feed settlers. Early mining operations also got in on the act by using jets of water to literally carve out mineral claims. Here’s a brief look at some […]
Factors that Affect Hydraulic Power and Performance
March 29th, 2017The moving parts of a hydraulic system are driven by fluid forces. Curiously, that term has a double meaning. There’s a fluid contained in the hoses, actuators, and pumps, but the second meaning describes the way in which the equipment moves. It moves with mercurial power, with understated strength. What about the moments when that […]
What are Gerotor Motors?
March 7th, 2017In order to understand how Gerotor Motors operate, we need to cut into one to see how its parts work. The teardown shows the discrete parts in motion. Unlike common motor geometries, there are two gyrating rotors inside this positive displacement mechanism. Primarily, the outer rim of the internal rotor is equipped with a number […]
Costly Mistakes That Most Hydraulic Users Make and How They Can Be Avoided
February 22nd, 2017Most hydraulic equipment owners and operators are a canny group, but that fact doesn’t seem to wholly eliminate costly mistakes. The errors stubbornly persist. Hard-earned lessons, however, are for gamblers and speculators, not for smart hydraulic users. This latter faction doesn’t subscribe to a wild throw of the dice, not when there’s a way to […]
Cleaning Procedure and Flushing of Hydraulic Cylinders
February 10th, 2017Ideal hydraulic systems don’t suffer from fluid contamination. They’re perfect machines, so there are no losses, just pure efficiency. Meanwhile, back in the real world, hydraulic cylinders accumulate dirt, the muck that hampers fluid power transmission. Let’s see what we can do about this build-up by establishing a fundamental cleaning procedure and flushing the muck […]
