In the study presented in this article, low-cost solutions for reducing throttling losses in hydraulic systems have been examined. In this context, two units using fixed displacement pumps were designed. The energy consumption of these hydraulic units during the working process ...
However, as demand for these resources increase around the globe, the mining industry has had to dig deeper mines to find higher-grade ore reserves to keep up. Deep, underground mining is more expensive because more energy is needed to excavate raw materials. This is due to increased demands ...
Using electricity for direct water heating in Brazil is therefore one of the most serious energy issues faced by the electricity sector. Because of that, the electricity grid is designed to supply this peak on the consumption, which implies high transmission and distribution costs for the system ...
Events larger than the design event can occur and when they do, losses can be even larger because of the increased development that occurred after construction of the protection structure—also referred to as the `levee effect’ in floodplain management (Tobin [1995]; Pielke [1999]). This was...
As is well known, kinetic energy can be generated by raising the potential energy of energy-storing media and converting the same. As a typical example, storage power plants having pump-fed power storage plants, wherein during times of an excess of electrical energy, the pumps are used to ...
Suitable adjustability may be provided via an appropriate hinge mechanism in combination with one or more hydraulic jacks or the like (not shown). Alternatively, any other variety of lifting and/or height-adjustment devices well-know to those skilled in the art may be used with equal efficacy....

Energy efficiencyThe current approach to hydraulic fracturing requires large amounts of industrial hardware to be transported, installed and operated in temporary locations. A significant proportion of this equipment is comprised of the fleet of pumps required to provide the high pressures and flows ...
