Fundamentals of Piston Pumps
June 8th, 2018Everyone knows how a single piston operates. In a sealed chamber, a metal rod slides forward then back. If there’s fluid in the chamber, the sliding rod generates suction as it moves forward, then the force reverses as the rod moves back. However, that basic linear action doesn’t easily translate to spinning force. Something else […]
Hydraulic Uses in Construction Work
May 29th, 2018Hydraulic power is utilized in all kinds of construction work. True, construction sites are full of workers, but for every group of workers, there’s a single fluid-powered crane or excavator doing the same work more efficiently. In fact, a typical day on a building site sees these sturdy lifters and diggers moving more than any […]
Hydraulic Fluid Viscosity and Its Effects in Hydraulic Systems
May 11th, 2018The lifeblood of a mobile hydraulic rig, its hydraulic fluid, keeps the system functioning like a great mechanical workhorse. Thanks to the forces stored in that oily fluid, the heavy equipment reliably moves bulky loads. The parts mesh with the oil to responsively direct that payload, and the operator loses himself in the work until […]
Filtration and Conditioning of Hydraulic Valves
April 30th, 2018What causes hydraulic systems to come to a crunching, lurching halt? Certainly, there are mechanical defects, breakdowns that can be traced back to a worn component. But fluid contamination is what we’re all about today. Hydraulic contaminants impair hydraulic valves, that’s just an unavoidable fact. Well, that’s not quite true, for there are filtration and […]
Parker Industrial Manifold Mounted Valves: Uses and Applications
April 17th, 2018Deep inside a hydraulics manifold, multiple fluid streams are on the move. The big metal block is distributing fluid power throughout the system so that a mobile lifter can control all of its moving parts. In plain terms, that machined block is the nerve centre, the system backbone. As for the Parker industrial manifold valves […]
