Hydraulic systems are impressive constructs. Arguably speaking, they’re even more sophisticated than an electrical circuit. In point of fact, most modern fluid-based systems include electrical and electronic elements, which either...
When you operate a pump, it is of the utmost importance that you take care to keep it properly functioning. Pumps can be hardy machines that work to keep a...
Machines and hygiene-sensitive applications are not naturally compatible. Generally speaking, oily machines and dirty mechanical gears should be kept far away from the food industry. To quash such food hygiene...
Let’s cut straight to the meat of the article. Open loop fluid systems start by sending a fluid stream through the system inlet, where it’s then picked up and boosted...
In hydraulics equipment, factory-branded pump and valve assemblies are put under a big microscope. Well, the instruments aren’t optical microscopes, but they do analyze the performance of these key system...
Along with the piston-driven pumps and actuators that form the main arteries of a hydraulic system, full-service hydraulic equipment manufacturers provide hundreds of different accessories. The system fittings refine certain...
Much like any other engineering discipline, hydraulics technology is rife with acronyms. The latest of which, NFPA cylinders, requires decoding. NFPA, strictly speaking, isn’t a descriptive acronym, it’s a shorthand...
Positive displacement pumps rule the hydraulics sector. Granted, an attempt by the sector to switch to non-positive displacement could be made, but the equipment based on this pump type would...
A system malfunction is taking shape, and a hydraulic fluid overheating problem is causing major headaches. If the equipment owner is to avoid popping a painkiller, he needs to know...
When Low-Speed Parker Geroter Motors run, they deliver massive quantities of torque. It’s this architecture that expedites traction-intensive fluid equipment applications. Tractors, construction equipment, forestry tools, they all benefit from...
Focusing once again on the mobile hydraulics sector, the moment has come to talk about equipment charging. Dynamically energizing the hydrostatic feed loop, a charge pump keeps the equipment responsive....
There’s a simple mathematical progression that rules fluid technology. Applying the principle to hydraulic and pneumatic systems, it goes something like this: for every high-pressure, super-sized fluid system, a comparable...
Hydraulic pressure intensifiers are built to deliver great quantities of pressure through a smaller than average package. Proven to take lower input energies and convert those fluid energies to higher...
Across two dimensions, a hydraulic flange misalignment error is causing trouble. The two collars are fastened evenly. All the way around, the bolts clamp the two faces together, with a...
In-hand, a Fairey Arlon replacement filter feels hefty and solid. The component is cylindrical, filled with microglass, a media that functions well in hydraulic applications, and ready for duty. Slipping...
Hydraulic hoses add flexibility to what would otherwise be an entirely rigid system. That’s an ironic perk, considering the very flexible nature of the energy transmission fluid. But it’s true,...
Tight dimensional tolerances exist between moving hydraulic components. There’s just not much clearance between the precision-manufactured parts as they slide past one another. Because of this tight-knit build, even a...
A power take-off is a singularly focused piece of hydraulically powered equipment. The device receives energy from a power source, then that energy is transmitted to a separate fluid-powered device....
Vane pumps work on a well-recognized principle. Mounted off-centre, a rotor spins in its pump housing. A number of bladed, or vanes, are fitted around this central section, and it’s...
Imagine a key hydraulic application. A generic fixed piston pump has decided to quit. The drive shaft stops spinning, the swash plate fails, and the cylinder block freezes. A company...
Everyone 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...
Hydraulic 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...
The 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...
What 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...
