The energy density of conventional hydraulic accumulators is significantly lower than competing energy domains. In this paper, a novel solution to improve the energy density of hydraulic energy storage, the flywheel-accumulator, is presented. The flywheelaccumulator integrates rotating kinetic and pneumatic energy storage, where the hydraulic fluid is used to change the mass moment of inertia o...

The article presents several current methods of remanufacturing hydraulic components, a trend that is encouraged, on the one hand, by concerns about reducing material consumption in context circular economy - some these materials being expensive or short supply. On other modern can lead to decrease energy devices concerned, due obtaining shapes are difficult achieve classical procedures. Among ...

A task of introduction separation processes damp dispersive materials are very actual for food and processing industry Ukraine other countries, because its solution will allow to resolve by most effective way a problem utilization such waste as alcoholic bard, beer pellets, beet press, coffee barley slime. In cases this is poured out in nearest reservoirs or on ground that leads environment pol...

The research involved the design of pipe positioning equipment for repair natural gas and oil pipelines. This paper presents results hydraulic straightening device its practical implementation. Several concept calculations analyses were carried out during design. final layout was selected from several possible solutions.

in this investigation, the performance of a tower for absorption of sulphur dioxide gas into calcium carbonate solution has been studied. the trays had no downcomer and the tower itself was a scaled down pilot from industrial equipment. the industrial scale tower was used for clean up of 110000 m3/hr gas using 40 m3/hr alkaline solution. the study was composed of two parts. in the first section...

Hydraulic vibratory hammer using the working principle of pile sinking is an important equipment in foundation construction, which can be used for and extracting piles. It has a wider range application than drop by impact method static press-in method, significantly reduce resistance piles during extraction improve efficiency. However, it difficult to avoid resonance phenomenon process starting...
