Filtration and Conditioning Hydraulic Systems: Do’s and Don’ts
August 17th, 2018Tight 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 slight filtration problem is going to cause trouble. Equipment conditioning fails next, with heat reducing the system’s formerly efficient fluid workings. Avoiding these pitfalls, we’re […]
Chelsea Power Take-Off: Uses and Applications in Hydraulics
July 26th, 2018A 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. Chelsea power take-offs push that fluid-mechanical principle to the limit. They’re built for heavy-duty applications, for big trucks and other workhorse usage domains. Look, there’s […]
Denison Vane Pumps: Single, Double, and Triple Configuration Differences
July 11th, 2018Vane 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 those rotating elements that impart fluid energy. Applied to Denison vane pumps, the principle is the same, but the device architecture is more refined. Starting […]
Parker Axial Piston Fixed Pumps Uses and Applications
June 25th, 2018Imagine 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 rep justifies the failure by talking about high operating pressures, but the excuses are far from satisfying. Parker axial piston fixed pumps won’t give out […]
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 […]
