👉 Disk fluid, also known as lubricant or thin film, is a critical component in the operation of rotating machinery such as turbines and pumps. It forms a thin, protective layer between moving surfaces, reducing friction and wear by minimizing direct contact between these surfaces. This fluid, often a specialized oil or grease, ensures smooth operation, enhances efficiency, and extends the lifespan of the machinery by dissipating heat and preventing metal-to-metal contact. The properties of disk fluid, such as viscosity and thermal stability, are carefully engineered to meet the specific demands of different operating conditions, making it indispensable in maintaining the reliability and performance of mechanical systems.
