“…By avoiding the use of antioxidant additions, it revealed a cleaner and more sustainable production. Olszak et al [83] studied the working fluids which are generated form vegetable oils. Compared to raspberry seed oil, blackcurrant seed oil was considered as a better option for hydraulic couplings.…”

In order to cope with the shortage of non-renewable energy and the increasingly environmental pollution, sustainable vegetable oils, as competitive alternatives, have widely been held in the good graces of the researchers. Vegetable oils are suitable for a wide range of applications such as biofuels and biodiesel. However, the development of vegetable oils is limited due to the characteristics of unsatisfactory oxidation stability and poor cold-flow properties. Chemical modification is considered as an effective solution to enhance the performance. The research progress of the chemical modification methods and applications of vegetable oils in recent years are summarized in this review. Reducing the content of carbon–carbon double bonds and increasing the degree of saturation are the keys to improve the physicochemical properties of vegetable oils. The prospects for the development direction and challenges of vegetable oils are proposed. Future research may focus on the use of multifunctional catalysts to optimize reaction conditions or to introduce active groups with lubricating properties in epoxidation reactions and explore the combination of chemical and auxiliary methods.

“…to reduce environment impact but on the other hand many industries are still using hydraulic systems 2 . Many studies are being conducted with the aim of replacing environmentally harmful hydraulic uids with ones that are compatible with nature and people 1,3,4 . Pneumatic and electric systems are much more environmentally friendly, because they don't have direct in uence the environment.…”

Different applications or industries use different systems for linear actuation, such as hydraulic, pneumatic, or electric. Electric systems are becoming more popular and are already replacing hydraulic systems in various applications. These are known to be potentially harmful to the environment, as large amounts of fluid can be released into the environment in the case of a pipe failure or other accident. This paper presents the results of a comparison between hydraulic, pneumatic and electric systems under variable conditions but with similar loads in all three systems. The common feature of all three systems is the input power, which was limited to 1.1 kW. There was no hydraulic accumulator in the hydraulic system and no pressure vessel in the pneumatic system, so no stored energy could affect system behaviour or results. The main difference between the observed systems was the displacement and power consumption profile. The smoothest response and the lowest energy consumption was achieved with the electric system, although both hydraulic and pneumatic systems can achieve a smooth response with a few modifications.

“…A critical element in hydraulic systems is the hydraulic oil, the main function of which is the transmission of fluid energy. The hydraulic oil also has additional functions, such as lubrication of moving parts, heat transfer, sealing of moving parts, corrosion protection, and contaminant discharge (Olszak et al 2020). The failure to perform one of these functions may result in components corrosions, orifice clogs, deterioration of the chemical properties and viscosity of the oil, and loss of oil additive properties.…”

Hydraulic systems are extensively used in industries. However, these systems must be free of contaminants to ensure their durability. When the contaminants entering the system are not removed with a suitable filter, sensitive parts such as pumps, motors, and actuators would be damaged. Therefore, hydraulic filters are critical elements in hydraulic systems. In this study, the flow and pressure drop in hydraulic filters were investigated experimentally and numerically. Although the main function of this device is to filter oil, it has many other functions in the system. Experiments were performed at eight Reynolds numbers in the range of 1250 -2350 at a constant viscosity. In the experiments, the pressure between the inlet and outlet of the filter was measured differently. The numerical results were used for detailed analysis of the flow after experimental verification. The analyses were performed using eight Reynolds numbers at laminar boundaries to examine the flow in the hydraulic filter. The results show that all surface areas of the filter element are not used homogeneously for fluid passage. The resultant pressure drop is due to the Dean vortex formed at the outlet of the hydraulic filter. The findings of this study can help better understand the flow recirculation regions that produce pressure drops and contaminant accumulation regions throughout a hydraulic filter from the inlet to the outlet of the flow path.
