“…The resulting frictional force generates heat, which increases the temperature in cylinder. In 2017, Ma, Wang, and Gu [9] conducted an experimental study of the friction of piston seals in cylinder as a function of different operating conditions. They found that under high-frequency operating conditions, the seal assembly T is the best.…”

Hydraulics is indispensable in everyday life because of its ability to work with large forces. Hydraulic cylinders are an important hydraulic element and contain different types of seals. This work presents an investigation of the influence of three different shapes and materials of piston seals in a hydraulic cylinder on the friction force. The friction was tested in two hydraulic fluids, water and mineral oil, at six different piston rod travel speeds on a test rig prepared for this purpose. It was found that the proportion of the friction force in mineral oil is between 60 % and 85 % of the friction force generated by the same piston seal in water. However, a long-term test carried out on a test rig provided data on the leakage of the piston seal before the start of the long-term test, after 50 km of travel, and after 100 km of travel of the piston rod at full load.

“…An example of a study that focused on seal geometry is that of Ma et al [ 4 ], wherein the authors present a test rig and the results they obtained after testing two sealing systems of hydraulic cylinder piston rods (the so-called M-sealing system and T-sealing system, respectively). The authors concluded their paper by recommending the M-system for stable operations conditions, while the T-system lends itself to high-frequency working conditions.…”

Optimizing the energy efficiency of hydraulic cylinder modern sealing systems requires, among other things, minimizing the developed friction forces. This can be achieved by manufacturing seals from polymer-based polytetrafluoroethylene-type materials (Virgin PTFE and filled PTFE) or from thermoplastic polyurethane elastomers. This paper presents a procedure for calculating and experimentally determining the friction forces developed in the coaxial sealing systems of hydraulic cylinders pistons. Three sealing systems made from different materials were tested under varying conditions of pressure and velocity on an experimental test stand set up by the authors. The paper concludes with data and recommendations for the selection of the optimum seal material in order to maximize energy efficiency. Our comparative research conducted on the seal materials led to the conclusion that for reducing friction forces in hydraulic cylinders, Virgin PTFE is the most adequate.

“…A test runs on a standard type of wiper seal by Nick Peppiatt in 2003 proved that a single lip wiper seal leaks more than a double lip wiper seal [4,5]. In another study conducted on wiper seals in 2018, test studies were conducted to determine the friction force in constantly developing hydraulic cylinders [6]. These tests on wiper seals are carried out by measuring the leakage amount by pressurizing after the seal is mounted in the cylinder and determining whether this amount is following the standards and customer demands [7][8][9].…”

Although the choice of wiper seal is not paid attention to in applications, the wiper seal is one of the most important elements of the system which isolates the hydraulic or pneumatic system from the external environment. Contamination in hydraulic and pneumatic systems can cause significant damage to metal parts of the cylinder, sealing elements, and other components of the whole system. This is the reason why Kastas Sealing Technologies develops a new test bench to perform wiper seal performance tests. This paper provides us with a technical overview of the design of the wiper seal test rig and performance analysis according to environmental effects on the wiper seal.
