👉 The deputy fluid, also known as the secondary fluid or auxiliary fluid, is a critical component in certain mechanical and hydraulic systems, often used to assist the primary fluid in performing its functions. It typically serves as a backup or supplement, providing additional lubrication, cooling, or pressure to ensure the smooth operation and longevity of the system. In some applications, it can also help maintain system integrity under extreme conditions or when the primary fluid supply is interrupted. This secondary fluid is usually inert, meaning it does not react chemically with the primary fluid, ensuring that the system remains stable and efficient.
