Rõhurelli

Rõhurelli is an Estonian term that translates to "pressure oil" or "hydraulic oil." It refers to a type of fluid used in hydraulic systems to transmit power. Hydraulic systems are found in a wide variety of applications, including construction equipment, automotive brakes, aircraft landing gear, and industrial machinery. The primary function of rõhurelli is to transfer force from one point to another through the medium of a liquid under pressure.

The specific composition of rõhurelli can vary depending on the intended application. However, it typically consists of a base oil, such as mineral oil or synthetic esters, along with a package of additives. These additives are crucial for enhancing the fluid's performance and protecting the hydraulic system. Common additives include anti-wear agents to reduce friction and abrasion, antioxidants to prevent degradation, rust and corrosion inhibitors to protect metal components, and viscosity modifiers to ensure consistent performance across a range of temperatures.

The effectiveness of a hydraulic system relies heavily on the properties of the rõhurelli. Key characteristics include viscosity, which determines the fluid's resistance to flow, and thermal stability, which indicates its ability to withstand high temperatures without breaking down. The fluid must also be incompressible to efficiently transmit pressure. Maintaining the correct level and quality of rõhurelli is essential for the longevity and optimal performance of any hydraulic system. Contamination or degradation of the fluid can lead to system malfunctions and costly repairs.
