Fluid power represents one of the possibilities of controlled energy transfer. Although nowadays especially political actors on a global level strongly push electric drives, hydraulics is still unavoidable. Fluid power also impacts the carbon footprint, so reducing this impact is a very important trend.

This work focuses on the process parameters of a model disk granulator for using waste silt in calcite production. This entails optimizing the disk’s inclination and rotation frequency, the quantity of supplied silt, the dynamic angle of the bulk material, the amount of added water, and the positions of the scraper, material feed, and wetting nozzle.

The success story presented in this article was developed during the first tranche of the R&D H2020 FF4EuroHPC Project. Partners Optimad, Aidro and CINECA teamed up to address specific business challenge in the manufacturing sector and overcome it with the help of High Performance Computing.

The study investigates the effects of various parameters on the root crack propagation and, consequently, the service life of the polymer gear. The international gear design standard ISO 6336 employs the 30° tangent method to determine the tooth’s critical section location.

In this article, the focus is on a central ventilation system that has a Dantherm RCV 320 installed. All air measurements, such as: air flow, air temperature, room humidity and CO2, were carried out in a residential prefab low-energy building located in Metlika.

This article presents new findings in the field of theoretical and practical aspects of the logistics of autonomous vehicles in the industrial sector, which are being investigated as part of an applied research project. The aim of the project is to use intelligent approaches and limited computing power to find optimal paths, temporal movement plans and task scheduling for a fleet of automated guided vehicles.

With the ability to drill to ever greater depths, new opportunities for oil production have emerged. It is estimated that currently more than 90% of all oil wells require artificial lifting. Currently, relatively old technologies are used for production, which have significant drawbacks that reduce oil companies’ revenues.

Renovation and upgrading of business or of work processes enables companies to manufacture and supply individualized products and to reduce production cycle time and labour costs. In the example of Robeta d. o. o. we analysed the existing state of the process of selling and ordering a motorhome (creating an order for the final product) and the production process.

Over time, the hydraulic component industry for oil hydraulics has gained a monopoly in development. Only components for oil hydraulics have been developed. Compared with oil, water as a hydraulic fluid has a better ecological effect, because it does not pollute the environment. Ecology has restarted the development of water hydraulics, which was used in the early days of hydraulics. The development of water hydraulics is progressing, but can it compete with oil hydraulics?

Hydraulic systems are very common in industry and other technical fields. The most frequently used valves for control are sliding directional control valves, which do not have seals on the control pistons. This causes internal leakage. The stability of the leakage is highly dependent on the purity of the hydraulic fluid. The thesis deals with the influence of the purity of the hydraulic oil on the durability and volumetric efficiency of the sliding directional control valve under consideration. As part of the thesis, a hydraulic test rig was designed and assembled, on which three durability tests of a hydraulic 4/3 directional control valve were performed.
