Understanding Open and Closed Loop Systems in Fluid Power
February 26th, 2019Let’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 by a hydraulic pump. The hydraulic oil leaves its reservoir, passes through a pump outlet port, and it’s channelled towards an actuator or another active […]
Factory Pump and Valve Assembly and Testing: Meeting Pump Curve Accuracy
February 14th, 2019In 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 components in great detail. Needless to say, the graphs produced by these analytical programs look quite outlandish, at least that’s how they appear to a […]
What are the Most Common Hydraulic System Accessories?
January 29th, 2019Along 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 performance-oriented qualities and generally improve the interface that forms between the components of a fluid circuit and its mechanical parts. Starting with filters and strainers, […]
What are NFPA Cylinders for Pumps?
January 15th, 2019Much 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 way of referring to a regulatory body, one that’s known as the National Fluid Power Association. Equipped with many resources, one of this regulatory body’s […]
Positive Displacement Pumps: Important Things that You Should Know
December 13th, 2018Positive 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 be unable to produce a positive internal seal. Yes, the gear would create a continuous flow, but that flow would vary as pressure changes took […]
