👉 The introduction fluid is a critical component in various fluid-based systems, such as hydraulic or pneumatic systems, designed to introduce or circulate a fluid into the system at the start or as needed. This fluid serves multiple purposes: it lubricates moving parts, reduces friction and wear, dissipates heat, and acts as a sealant to prevent leaks. In hydraulic systems, the fluid also transmits power from the pump to the actuators, enabling precise control and movement. The introduction fluid can be oil-based, water-based, or even air, depending on the specific application requirements, ensuring optimal performance and longevity of the system.
